▼ ABSTRACT Most sandy beaches around the world have been under the threat of being eroded in the past six decades, resulting in shoreline retreat; thus, calling for various shoreline protection devices to be constructed to preserve the well-being of coastal habitants. To achieve this purpose, research on shoreline changes and development of numerical or mathematical models for predicting shoreline changes would help attain the goal of sustainable use of coastal land. This thesis reports preliminary engineering applications of GENESIS that have become a popular tool for modeling long-term shoreline changes. The aim of this study is to predict the potential shoreline change in the light of different layouts of shoreline protection devices. The topics addressed in this report include the discussion on the parameters in GENESIS; shoreline changes in the lee and/or on the back of single groin and single detached breakwater with normal or oblique wave incidence; comparison on the efficiency of beach accretion as a function of gap width between structures and the sequence of their construction, as well as assessment on the restraint from the two different boundary conditions used in GENESIS. The results of modeling using GENESIS are then verified using the result based on the empirical parabolic bay shape equation and a physical scale model, in order to test the feasibility of applying GENESIS for practical engineering uses. From the results of this study, it can be stated that GENESIS is valuable reference tool for engineering design, despite some shortcomings in setting up boundary conditions and the invariant nature of and values which do not respond to the process of changing shoreline curvature. However, the GENESIS system would have a positive contribution to the modeling of shoreline changes upon the construction of protective devices on a coast. Advisors/Committee Members: John R.C.

▼ Urban areas are major concentrations of culture, acting as centers of trade, industry, innova - tion, and daily living. Since the industrial revolution, cities have continuously developed and further concen - trated human capital. Urban areas face a multitude of challenges, from efficient transportation to resource distribution to public safety and crime prevention. To - day, the number of people who reside in cities outnum - bers the number of people who reside outside of cities, and the proportion of the population that lives in urban areas is expected to increase to nearly 70% by 2050. As this occurs, we must make sure our cities can effectively day, the number of people who reside in cities outnumbers the number of people who reside outside of cities, and the proportion of the population that lives in urban areas is expected to increase to nearly 70% by 2050. As this occurs, we must make sure our cities can effectively provide residents with the resources and services they need not just to live but to thrive. Meanwhile, climate change threatens the health and safety of all our living spaces, especially in cities. In the near future, our cities will not only have to accommodate more people, they will also have to adapt and respond to the effects of climate change in order to maintain conditions that are safe, healthy, and liveable. The effects of climate change are far-reaching. They include increased precipitation and other extreme weather events—which result in a heightened risk of flooding and the endangerment of lives and property—and the increased fragility of ecosystems and biodiversity as they also attempt to adapt to changing living conditions. Urban environments are especially vulnerable due to large amounts of impervious surfaces, which prevent rain water infiltration and absorb heat, and limited space for ecosystems that can help mitigate these effects. This project is located in the watershed of the Watts Branch, a tributary of the Anacostia River, and spans parts of both Prince George's County, Maryland, and the District of Columbia. It crosses densely populated urban neighborhoods, some of which are home to socially and economically vulnerable populations. Some of its residents are low-income families or live in affordable housing communities. Washington, D.C. and the State of Maryland have both experienced catastrophic flooding events in the last several years, largely driven by precipitation. Flooding in the Federal Triangle has threatened not just homes and businesses but also irreplaceable national historical documents and artifacts. Similarly, catastrophic and fatal flash flooding suffered in Ellicott City, MD, in 2018, disrupted that city's leading industry, tourism.2 These events are devastating—as they will occur more frequently as climate change continues to have greater impacts, it is thus essential to ensure that this community is protected against these impacts. One way to address multiple challenges within an urban environment is… Advisors/Committee Members: Jones, Stan (advisor), Gronewold, Andrew (committee member).

▼ The objective of this research is to use geographic information systems (GIS) to quantify shoreline position change during 1954 and 1999 for Sapelo Island and Jekyll Island in Georgia, USA. Shorelines from multiple years were manually traced from digital raster graphics, aerial photographs, digital orthophoto quad quadrangles and a lidar image using ArcView GIS software, Version 3.3. This study showed that the northern ends of Jekyll and Sapelo islands are eroding, whereas the southern ends are accreting. Mann-Whitney test (two-tailed) indicated that the mean accretion rates and annual change rates (regardless of direction) of the two islands differed statistically during 1954-1974,1974-1993 and 1954-1999. The mean recession rates were significantly different during 1954-1974 and 1974-1993, but not so for 1954-1999. Human activity exerted a heavy influence on the shoreline change. Quantifying shoreline change provides useful data on the effects of engineering structures on erosion and is important for coastal zone management and planning.

▼ Assessing the possible impacts of future climate change is a major issue currently requiring attention by governments worldwide. By assessing the likely impacts of climate change for the full range of environmental and regional sectors, governments will be able to prioritise adaptive strategies to manage the climate change impacts in an economically responsible way. This study represents a portion of a NSW state government funded study assessing the possible impacts of climate change to the NSW coastline. As part of this study, a modelling approach capable of assessing the impact of climate change to the existing shoreline has been developed. The developed modelling approach, based on existing coastal engineering theory, has been designed specifically to assess the impact of climate change on shoreline response for an open coast beach. The time stepping model further develops the Miller and Dean (2004) cross-shore model using a geometric representation of the cross-shore profile. The geometric approach has been applied using Bruun Rule style conservation of mass principles. To assess the possible shoreline response to the combined impact of climate change driven sea level rise and variations in wave climate, developed cross-shore and longshore models have been dynamically linked. Combining of the modelling programs has enabled an efficient way to assess the likely impacts of climate change on shoreline response. Specifically, the assessment of the likely impacts of climate change variations predicted by McInnes et al. (2007) on Wooli Wooli Beach has been undertaken using this developed modelling approach. Summarising the findings specific to Wooli Wooli Beach, using the developed assessment approach, accounting for the combined impact of climate change on cross shore and longshore sediment transport processes, the results indicate there is a significant non-uniform alongshore response to the climate change forcing. The results show that greatest shoreline recession is likely to occur along the southern section of Wooli Wooli beach, adjacent to the northern training wall of the Wooli Wooli River. North of this location the shoreline recession results are reduced, with the northern section of Wooli Wooli beach exhibiting the smallest recession. Alongshore, for the three assessed climate change scenarios, at the southern end of Wooli Wooli beach where the predicted erosion is of the greatest magnitude between 73m and 83m of shoreline recession is predicted. Comparing the various scenario results, it is evident that the projected increases in sea level dominate the shoreline response at Wooli Wooli. Projected changes in wave climate are predicted to have an effect of the future shoreline evolution, though the magnitude of change is comparably less than that resulting from sea level rise in isolation. In the broader context of shoreline response to climate change, the Wooli Wooli assessment results highlight some interesting trends. The results indicate that shoreline response to sea level rise is highly non-uniform for…

Shoreline change is affected by a multitude of complex processes operating at various spatiotemporal scales. Comprehensive multi-year simulations of shoreline changes and forecasts are feasible with process-based models. However, these detailed and computationally expensive numerical simulations do not always lead to increased predictive skill in comparison to simpler shoreline models (Davidson et al., 2013). ShoreFor (Davidson et al., 2013) employs the concept of (dis-) equilibrium of shoreline location following Wright and Short (1985). In this research, the current ShoreFor model (Splinter et al., 2014) is used as baseline. ShoreFor seeks for an optimum decay factor that best describes the morphological response of a coastal system to the corresponding hydrodynamic forcing. This parameter is measured in days and effectively controls the shoreline response timescale. Currently, the ShoreFor model provides a single value for φ, representing a single dominant shoreline response timescale. As morphological systems can contain multiple dominant timescale responses, a new approach to multi-timescale shoreline change modelling is proposed. Three video-derived datasets are used to improve the model towards a generally applicable one which incorporates multiple temporal scales: Narrabeen (Australia), Nha Trang (Vietnam) and Grand Popo (Benin). Each dataset has different hydrodynamic- and morphological characteristics. The storm timescale is a dominant mode of shoreline response for Narrabeen, whereas for Nha Trang and Grand Popo the seasonal timescale is the most dominant. Furthermore, all sites are subjected to more modes of shoreline response such that the application of a single memory decay factor will hamper shoreline modelling. The existing model is improved using 3 steps.In the first step, the raw wave- and shoreline signals are filtered to distinguish temporal scales. Then filtered temporal scales in shoreline position are forced with the corresponding scales in the wave signals. For each temporal scale, a distinct memory decay factor φ is found. In the second step, the effect of small temporal scales in wave forcing on larger temporal scales in shoreline position is accounted for. The improved model takes this effect into account using the envelope of the filtered wave signals. The envelope is used to force the model and to calculate shoreline change with the same timescale. In the third and final step, the effect of large temporal scales in shoreline position on smaller scales in shoreline response is accounted for. The efficiency with which waves induce cross-shore sediment transport can be dependent on the large scale shoreline variation. A time varying response factor c is introduced that controls the efficiency with which waves induce cross-shore sediment transport. The dynamic response factor varies over time with the shape of the larger scale shoreline signal: it represents the effect of the large scale shoreline variation on the smaller scale shoreline response.

The unprecedented changes in climate we are experiencing today drive sea level variations that influence the morphology of coastlines. Many areas experience high rates of sea level rise combined with tectonic movements that abruptly change coastal morphology. One problem with assessing these areas is the lack of data available. Although recent developments have improved our ability to gather information from shallow coastal areas, these systems are expensive and require highly skilled operators and analysts. To alleviate this problem, a portable survey system was developed and tested on the coast of Crete, Greece to determine shoreline changes since the Bronze Age. Results of the survey indicate that the shoreline submerged 10.3 m and moved a minimum of 28 m inland over the past 3463 years. By understanding shoreline change in areas faced with sea level rise compounded by tectonic movement, we can improve our planning and disaster management capabilities.

Developing a better understanding of beach response to a variety of forcing mechanisms is necessary in efforts to predict and mitigate the effects of both short-term events and long-term trends on shoreline change. The evolution of beach morphology has been studied on time scales of days to weeks but rarely repeatedly during large swell events due to the limitations posed by traditional surveying methods. With the advent of Terrestrial Laser Scanning (TLS), studying the beach response to individual storm events and even wave events has become possible. TLS was used to quantify morphological changes at Waikiki Beach, a high traffic and economically important beach, on Oahu, Hawaii's south shore. TLS scans were generated approximately every 30 minutes for a 3-day period starting at the peak of an August/September 2011 swell event that was the largest south swell on record since September 2005 (Caldwell, 2007). A digital elevation model (DEM) of Waikiki was produced to calculate relative subaerial cumulative beach volume change over the course of the study period and three sections of Waikiki were used for analysis. These three sections accreted between ~11 and 29 m3/m of sediment on the subaerial beach during the study period, with most accretion occurring during the falling tide following the highest tide of the day. Little or no cumulative beach volume change was observed preceding these accretionary phases. Pressure sensors deployed at the study site were used to obtain estimates of the incident and nearshore wave conditions in approximately 6.9 and 1.5 meters water depth respectively. The observed nearshore swell wave height was tidally modulated, and we speculate that the water level associated with the highest tide of the day allows wave energy to reach the shore and deposit sediment onto the subaerial beach. A one-dimensional numerical model, XBeach, was implemented to compare with the observations and the model is shown to inaccurately predict the subaerial beach response. The model is forced with observed incident wave and tidal conditions and predicts erosion of the subaerial beach between ~5 and 10 m3/m instead of the observed accretion. The model results from XBeach reveal a disparity between observations of accretion and the modeled erosion of Waikiki's subaerial beach. In addition, the one-dimensional XBeach model fails to accurately predict nearshore infragravity wave conditions and subaerial beach response in Waikiki during swell events of this magnitude. This thesis demonstrates the utility of TLS in studies of morphologic change on beaches with an adequate vantage point for studying the evolution of beach morphology, especially on time scales previously too short for traditional survey methods. It also reveals accretionary characteristics of subaerial beach response in Waikiki to this large swell event and tidal levels, as well as limitations of the one-dimensional XBeach model in predicting subaerial cumulative beach volume response in Waikiki.

▼ This thesis utilises a range of methodologies to investigate the historical shoreline change and beach morphodynamics at Rapahoe Bay, West Coast, New Zealand. Rapahoe Bay is a small embayment located 15 km north of Greymouth, and contains a complex and dynamic environment under a dominant swell condition. The objectives of this thesis include the investigation the coastline history through aerial photographs and relevant literature, identify and quantify historical shoreline change and the processes that have induced change, examine the short term and seasonal changes in beach profile, identify and quantify wave and transport process and to test the applicability of the zeta shoreline curve on a composite beach. This combined approach investigates the dynamics and process drivers involved in coastline change. This thesis contributes to the research gap of understanding morphodynamic behaviour and controls of composite beach under a dominant swell. Composite beaches types are a variation from mixed sand and gravel beaches with distinct morphological differences. This thesis provides an insight in to the morphodynamic behaviour of composite beaches. The study area contains a small village based by the shoreline and the potential coastal hazard that threatens people, property and infrastructure. Therefore the results from this thesis have an important management implication towards mitigating coastal hazards. The historical coastline change was induced through a combination of wave processes and transport, composite beach morphodynamic behaviour, anthropogenic influence and planform shape. Results show that human infrastructure restricted the retreat of a small hapua landward of the gravel barrier. A combination of change in sediment supply, consistent sediment transport and a high wave energy environment resulted in rapid landward retreat through gravel rollover and coastal erosion. The gravel barrier morphodynamics include increase in crest elevation, steeper shore gradients as a response to high swells resulting in erosion or rollover. The wave environment includes a sediment transport hinge point due to a dominant wave refraction and changes in the shoreline orientation, which further induces coastal erosion. The valid applicability of the zeta planform shape concludes that the shoreline may further iii retreat due to geological controls, potential sediment transport and the transgressive nature of the composite beaches. The combination of methods and results provide both quantified historical change and also potential future scenarios of coastline reshaping. These methods and results are applicable not only to Rapahoe but along other West Coast composite beaches, and the validity of the combination of methods provides a greater understanding of the behaviour of morphodynamic composite beaches and provides quantified results of historical shoreline change and sediment transport at the field site.

▼ The Virginia barrier islands stretch from Assateague Island in the north to Fisherman's Island in the south. This string of islands is subject to frequent North Atlantic extra-tropical storm and hurricane influence. In addition, sea level rise has the potential to cause continued shoreline loss and inlet widening for this island group. This dissertation describes the effect of sea level rise, changes in wave height, and teleconnection pattern (AO, NAO, and MEI) correlations to shoreline location changes to the islands and inlet location and width changes. Locations of island shorelines were determined from satellite and aircraft images using ArcGIS software and the USGS Digital Shoreline Analysis System (DSAS). Geographically registered images were digitized, and multiple transect locations on each island were measured from a common offshore baseline using DSAS. The resulting distances along with the remote sensing image dates were used to construct time series of shoreline location for each island. Data frequency was controlled by image availability, and ranged from weekly to semi-monthly. Approximately 250 shorelines per island from 1990 to 2014 were digitized. The results were then interpolated to give a monthly shoreline location for each transect. The combined observations were analyzed by empirical orthogonal function (EOF) and wavelet analysis. The analysis shows that the barrier islands are moving to the south as well as becoming narrower. As a group, the shoreline movement is primarily correlated with sea level change (r2 = 0.41). The islands also respond to storms and other episodic events. The response can be resilient or catastrophic depending on the extent of shoreline loss which precedes the event. If the island shoreline has narrowed to a width that cannot withstand wave and high water level induced loss, the island and associated shoreline is permanently lost. The rate of shoreline loss returns to the pre-storm rate within several weeks after the events unless island shore is permanently lost during the event. Increased losses of island length were concentrated in years 2004-2005 and 2009-2010. Wavelet analysis confirmed and explained the EOF results by showing the presence of shoreline change cycles which become more intense at times of shoreline loss. A large reversal of shoreline loss was caused by the placement of 3.5 million m3 of sand on the south end of Wallops Island in 2012 and the attachment of a large offshore shoal to the north end of the same island. Wreck and Ship Shoal Islands have had a net shoreline gain over the study period but with continued southward migration. There are ten inlets between the Virginia Barrier islands. Five of these had width increases of more than 100% during the study period. Two of the five widened by more than 200%. As the barrier islands have become shorter, the inlets have become wider. Due to the episodic nature of the loss of some islands, the inlet width gains have also been episodic.

▼ The study of shoreline change in New Zealand is very important, particularly now given the threat of climate change and its associated sea-level rise. Yet, there has not been a comprehensive study on shoreline change around New Zealand for over three decades, since Gibb's (1979) nationwide synoptic overview. Because Gibb's (1979) study was synoptic, the reasons behind the measured shoreline changes were unable to be determined. The role of vegetation change, such as the introduction of Ammophila arenaria (marram grass), is just one of the potential causes of shoreline change Gibb (1979) was unable to consider. In addition, Gibb (1979) did not have the benefit of modern shoreline mapping technology, such as Geographic Information Systems (GIS) and Global Positioning Systems (GPS). This study examined four study sites: Mason Bay, Stewart Island; Kaitorete Barrier, Canterbury; Big Bay, Fiordland; and Tahakopa Bay, the Catlins. These four study sites are located in some of the most isolated areas of New Zealand, and are among the least affected by human occupation. In examining the shoreline change at these sites, modern shoreline mapping technology was used. Aerial photographs dating from 1943 were added to GIS software (ArcGIS) and orthorectified. The location of the shoreline, as indicated by the seaward extent of the dune vegetation, was mapped for each aerial photograph. GPS data taken at the shoreline of the sites during 2011 (except Big Bay) were added to the maps. Environment Canterbury (ECan) beach profiles were plotted from eight locations along the length of Kaitorete Barrier. The temporal and spatial decadal shoreline changes were then analysed. This study reached three main conclusions. (1) The introduction of Ammophila is able to force shoreline progradation, as shown at Mason Bay. There was spatial variability in progradation alongshore at Mason Bay, as with all four of the study sites. (2) A dwindling modern sediment supply may be significant on coastlines with strong alongshore littoral sand transport systems. It is considered that a dwindling modern sediment supply to Kaitorete Barrier has encouraged the naturally-occurring process of shoreline reorientation to continue; this is likely to continue into the future. (3) The two most remote, and least affected by human influence, of the four study sites – Big Bay and Tahakopa Bay – experienced virtually no shoreline change over the last 54 and 63 years respectively.

▼ In this thesis, a numerical simulation model is applied to investigate the long-term shoreline changes behind detached breakwaters. The model includes three components, namely a wave model, a current model, and a shoreline change model. In the numerical simulations, various combinations of wave conditions and the placement of detached breakwater are chosen to explore the effect of detached breakwaters on the shoreline change. The results of calculation show that with incident wave angles within 0~45, wave height in the range of 0.5~1.5m, or the offshore distance to the detached breakwaters being 60~120m, the larger in any one of these three parameters is, the bigger the erosion distance onshore from the original shoreline and the extent of salient offshore are behind detached breakwaters. When incident angle of the wave increases, shoreline plan form becomes skewed, and the time required to arrive at equilibrium also increases, in addition to the position of the top of salient moves downcoast. Within the wave periods of 7~10 seconds tested, waves with large period are found to show slight decrease of the erosion distance onshore and the extent of salient offshore behind detached breakwaters. The plan form of the salient is not affected by wave period. However, the larger the wave period is, the sooner the long-tern shoreline will result. Moreover, for a detached breakwater constructed in the range of offshore distances within 1.0ï¼S/Bï¼2.0, variable offshore distances do not produce much difference in the erosion distance onshore and the extent of salient offshore behind detached breakwaters, and salient only will form. In the case of the S/B =< 0.8, a tombolo will result. Finally, the results of shoreline plan form from the numerical modeling are verified by the empirical parabolic bay shape equation of Hsu and Evans (1989), a small-scale hydraulic model, and two numerical models based on GENESIS and LITPACK. Overall, the result are in good agreement with these four different approaches, and therefore, the present model is suitable for practical engineering applications.

▼ This study examines lacustrine shoreline sediment records of the Bonneville lake basin in North America. One of the most straightforward, robust, and useful characteristics of lacustrine shorelines is that shoreline features always form at water's edge to mark where the lake surface level is. Hence, mapping shoreline elevations enables researchers to reconstruct such physical dimensions of a paleolake as surface area, depth, and volume through geographic surveying, geomorphology, stratigraphy, sedimentology, tephrochronology, and radiocarbon dating. Good age control also makes it possible to put together lake size data from different time periods to chronicle details of when and how the lake changed its size in the past. Based on 200 radiocarbon dated shoreline data, this study presents a lake size change chronology of the Bonneville basin during the ice ages from 43,000 to 10,000 calendar years before present. Comparing the Bonneville basin lake record with the well resolved, high resolution ?18O records from the Greenland ice sheet, Venezuelan varved ocean sediments, and Chinese cave stalagmites reveals that timing, magnitude, and duration of all major lake change events in the Bonneville basin are in phase with large-scale climate change events. Close synchroneity of Bonneville lake events with Asian and East Asian monsoon intensity fluctuations during the last deglaciation also illustrates that the Bonneville basin lake system was highly sensitive or responsive to hemispheric scale, abrupt climate change events.

▼ The vulnerability of a coast is related to its geomorphic condition, slope status, past shoreline change, rate of relative sea-level rise (SLR), tidal range and exposure to waves. A Coastal Vulnerability Index (CVI) was developed by Gornitz and Kanciruk in 1989 which has been adopted and modified by subsequent researchers and organizations. The coast of Bangladesh is considered to be one of the most vulnerable in the world, but a thorough assessment of its vulnerability has not been undertaken previously. This study has developed a vulnerability index for the entire coast of the country based on these six physical variables. A total of 957 cells of the coast (excluding river mouths) have been divided into five vulnerability classes for all of the variables except SLR. The SLR variable has been divided into four vulnerability classes. The geomorphology variable has been mapped from satellite imagery to classify the coast into categories such as mud flat, sandy beach, mangrove or cliff. Elevation obtained from SRTM, ASTER and GTOPO datasets has shown contradictory results, indicating overestimated elevation in dense forested areas, especially in the Sundarbans coastal zone. Therefore, slope has been used in preference. The shoreline of the coast has been detected using a band ratio approach to discriminate the water line on Landsat images over a 20- year period from 1989 to 2009. Rates of shoreline change have been calculated using the End Point Rate (EPR) method in the Digital Shoreline Analysis System (DSAS) extension in ArcGIS®. The coast has been observed to be very dynamic with recorded erosion of 285 m/yr and accretion of 633 m/yr. Sea-level rise has been calculated using tide-gauge data indicating high variability along the coast. However, relative sea-level change along the Bangladesh coast is still unclear. Similarly, tidal range obtained from secondary sources has been found to be variable throughout the coast, with the highest tidal range around the Feni River estuary, including Sandwip Island. Although most of the studies have considered wave heights as a variable in the CVI calculation, this study has considered surge height because of the frequent cyclones hitting the coast. Coastal vulnerability indices for the Bangladesh coast have been calculated using four formulae: i) product mean ii) average sum of squares, iii) square means of product mean, and iv) sum of product methods. Additionally, the fourth formula has been modified to explore a more reliable vulnerability measure for the coast. Different formulae have…

▼ In Alabama, the term "coastal shoreline" applies to the Gulf shoreline and the shorelines of estuaries, bays, and sounds connected to the Gulf of Mexico and subject to its tides. However, Alabama shoreline studies have yet to include Little Lagoon, which has been connected to the Gulf of Mexico for most of the last 200 years, according to historical charts. This study used historical nautical charts, aerial photographs, and LIDAR derived shorelines from 1917 to 2004 to analyze shoreline change on Little Lagoon and its adjacent Gulf shoreline. The high water line was used as the common reference feature, and all shorelines were georeferenced, projected, and digitized in a Geographic In-formation System. Between 1917 and 2001, the Gulf shoreline eroded an average of 40 m over 12.7 km, with some transects eroding almost 120 m while others accreted almost 60 m. The greatest changes to the Gulf shoreline were found near natural inlets, downdrift of jetties, and coincident with nourishment projects. Between 1955 and 1997, Little Lagoon shrank 0.5%, or 51.4 km², from 10,285.9 km² to 10,234.5 km². The greatest changes to Little Lagoon were found on its southern shoreline and near inlets, human development, and hurricane overwash fans. A correlation analysis conducted on the Gulf shoreline and Little Lagoon' s southern shoreline indicated that although weak overall correlation values exist when the entire 12.7 km study area is compared, strong correlation values are obtained in some areas when compared over one kilometer sections. The strongest correlations were found in the same locations as the greatest changes. Advisors/Committee Members: Campbell, James B. Jr. (committeechair), Kennedy, Lisa M.

▼ Rising sea level is threatening coastal areas, particularly those in the Caribbean which rely heavily on tourism and marine resources to support local economies. The purpose of this study is to analyze shoreline position along the south coast of Jamaica to determine the locations and rates of coastal change. IKONOS satellite imagery sets for 2003, 2007 and 2012 were used to monitor land use and shoreline changes along Black River Bay, including Galleon Beach Fish Sanctuary, in St. Elizabeth, Jamaica. In particular, the effect of Hurricane Ivan in 2004 on shoreline changes was evaluated. Erosion rates were significantly higher during 2003-2007, the period including Hurricane Ivan (-0.90 m/yr), with reduced erosion rates and some recovery by deposition observed during the post-hurricane period (0.21 m/yr). Little to no changes were observed along limestone headlands and mangrove swamps with highest rates on sandy beaches lacking offshore coral reef protection and exposed to storm waves. Overall, shoreline recession averaged -0.31 m/yr during the study period with a peak erosion rate of -1.13 m/yr at Parrottee Point. Within the next 10 to 30 years, an expected 9 km of mangrove swamps and over 100 buildings are at risk due to sea level rise and shoreline erosion. Advisors/Committee Members: Robert Pavlowsky.

▼ This dissertation combines three separate studies that measure coastal change using airborne laser data. The initial study develops a method for measuring subaerial and subaqueous volume change incrementally alongshore, and compares those measurements to shoreline change in order to quantify their relationship in Palm Beach County, Florida. A poor correlation (R2 = 0.39) was found between shoreline and volume change before the hurricane season in the northern section of Palm Beach County because of beach nourishment and inlet dynamics. However, a relatively high R2 value of 0.78 in the southern section of Palm Beach County was found due to little disturbance from tidal inlets and coastal engineering projects. The shoreline and volume change caused by the 2004 hurricane season was poorly correlated with R2 values of 0.02 and 0.42 for the north and south sections, respectively. The second study uses airborne laser data to investigate if there is a significant relationship between shoreline migration before and after Hurricane Ivan near Panama City, Florida. In addition, the relationship between shoreline change and subaerial volume was quantified and a new method for quantifying subaqueous sediment change was developed. No significant spatial relationship was found between shoreline migration before and after the hurricane. Utilization of a single coefficient to represent all relationships between shoreline and subaerial volume change was found to be problematic due to the spatial variability in the linear relationship. Differences in bathymetric data show only a small portion of sediment was transported beyond the active zone and most sediment remained within the active zone despite the occurrence of a hurricane. The third study uses airborne laser bathymetry to measure the offshore limit of change, and compares that location with calculated depth of closures and subaqueous geomorphology. There appears to be strong geologic control of the depth of closure in Broward and Miami-Dade Counties. North of Hillsboro Inlet, hydrodynamics control the geomorphology which in turn indicates the location of the depth of closure.

▼ Anthropogenic stabilization of erosional shorelines by hard-armoring structures is used for protection of property, especially if buildings, historical monuments, cultural resources, or other infrastructure are present. The post-installation effects of shoreline stabilization structures on adjacent shorelines in the back-barrier marshes of coastal Georgia are a concern, and interest in living shorelines as erosion control devices has increased because of their use of natural materials and vegetation. AMBUR shoreline analysis software was used to calculate pre-and post-installation shoreline change rates of shorelines adjacent to riprap and bulkhead structures. There was no significant difference between the post-installation shoreline change rates of the structures, but individually there is erosion immediately adjacent to four of the structures after installation (the end-around effect). Vegetation percent cover, stem height, and stem densities were measured in addition to shoreline change rates. Analysis of vegetation showed similarities between shorelines adjacent to living shorelines and control sites. There are significant differences in to vegetation cover between riprap structures and the control sites, and these results showed that installation of riprap structures significantly changes the vegetation cover of the adjacent, unprotected shorelines. These results provide novel methodologies and initial data for determining the influence of erosion control structures on back-barrier shorelines. The researcher identified limitations with available data sets and supplied needed results to researchers for future study and to coastal managers for better informed decision making about the effects of shoreline stabilization structures on adjacent shorelines.

▼ Coastal erosion is, more than ever, a global problem. By adopting a high-efficient, cost effective and reliable numerical model, it would help predict and manage erosion, as well as alleviate many coastal problems. This thesis reports the results of a though out investigation on the popular one dimension long-term shoreline change model – GENESIS, analyze its suitability, sensitivity and technical difficulties likely to encounter while using the model, with the aim to predict the effect of coastal structure on shoreline changes. Prior to perform a modeling task, this report provides constructive recommendation on the setting of the length of shoreline to be covered in the modeling, boundary conditions, grid space, transport parameters K1 and K2 and revision of wave angle, followed by verification using results of several physical scale models, in order to enhance the reliability of the modeling and the parameters employed. Finally, reasonable ranges of K values are proposed. For modeling shoreline changes induced by a detached breakwater with normal incident waves, an empirical equation is proposed to determine the K ratio(K2/K1), which offer a useful guide in achieving the results with in a tolerance limits of 12%~-7%. When consider oblique wave incident to single detached breakwater, K1=0.6 is used and the ratio of K2/K1 ≈ 0.25~0.5. For modeling the effect of a single groin, the present study suggests K1=0.6 and K2/K1 ≈ 1~2. On the basis of these principles for setting the K values, the results are then applied to model the shoreline changes due to the installation of detached breakwater and groin. From the results of this study, for normal wave incident to single detached breakwater, it shows that for a small ratio of the offshore distance to the length of the breakwater S/B or a larger wave height, the salient dimension will increase and wave period has almost no effect on the results produced; for small S/B ratio, the maximum downcoast retreat increase, and its quantity is almost not affected by the wave conditions imposed. For oblique wave incident to single detached breakwater, it shows that for a larger wave angle, a small S/B or a larger wave height, the salient dimension will increase and wave period has almost no effect on the results produced; for larger wave angle or small S/B ratio, the maximum downcoast retreat increase, and its quantity is almost not affected by the wave height and wave period. For modeling the effect of a single groin, it shows that for larger wave angle or length of groin, the maximum downcoast retreat increase, and its quantity is almost not affected by the wave height and wave period.

▼ This research considered a variety of scientific approaches in Geographic Information Science (GIScience) that can be used to provide geospatial input to reliable decision making systems for sustainable development and preservation planning. Theoretical aspects of GIScience including conceptualizations, modeling, spatio-temporal representations, and spatial analysis were combined with emerging geospatial technologies such as Light Detection and Ranging (LiDAR), very high resolution (VHR), and image fusion in Remote Sensing and Web-based geographic information systems (GIS) services. These methods were used to provide criteria and scientific findings that can be used to create master plans for coastal development and conservation. Questions considered in this dissertation are: (1) How should coastal barrier islands be demarcated and assessed for polices limiting the percentage of development?; ( 2) Can the availability of sandy beaches be estimated and predicted for tourism recreational purposes while regarding criteria of cultural and natural resource preservation?; (3) How effective are revetment rocks as a protector of the mainland from physical processes of erosion, accretion and wave action and what geospatial tools can be used to monitor coastal shorelines?; and (4) What image processing techniques produce optimal VHR satellite images identifying land use land cover (LULC) in coastal environments? With respect to these considerations, this dissertation aimed to geospatially demarcate the land and ocean boundary of Jekyll Island State Park off the coast of Georgia, USA based on different tide level assumptions used by state and federal agencies. Results quantified differences in island size up to 7.2 % depending on jurisdictional sea levels and different back-barrier marshland and ocean-front shoreline elevations in Chapter 2. Beach availability was geospatially assessed for recreational tourism management and vulnerability of shoreline integrity in revetment rock areas in Chapter 3. Finally optimum pansharpening techniques were evaluated using VHR satellite imagery for best geospatial data to identify features in dynamic coastal zones in Chapter 4. These findings will allow coastal managers, residents, and tourists to make appropriate decisions for sustainable development and preservation of coastal barrier islands.

▼ Earth has experienced many glacial cycles over the ̴ 2.5 million year long Quaternary period. During the latter part of the Quaternary, roughly the last 800,000 years, each cycle has been of duration ̴ 100,000 years and has included extended periods of glacial conditions, with ice sheets in the northern hemisphere. In-between those periods, intervals with periglacial or temperate conditions in northern latitudes have occurred. Global sea level has, as a response to the formation and melting of ice sheets, fluctuated over 120 meters. Thus, the global climate cycles have been the main driver for the location of continental coastlines, environmental changes in the past as well as the resulting present-day landscapes. Recent human-induced climate change is now also affecting the landscape. In this thesis, I examine the use of global climate models as input to exploring local landscape evolution over glacial cycles. An approach is proposed for landscape description that is designed for use in long-term safety assessments related to landscape development into the far future. The approach is illustrated by results of work that shows methods applied to a site-specific landscape development model using climate and climate-related data. Site-specific data is utilised to gain site understanding from which conceptual ecosystem models are developed for present day conditions, and to inform landscape narratives. Concentrations of elements are used to infer the characteristics of transport processes in the landscape over time. The results from the above studies are discussed in relation to the general hypothesis in this thesis; that by considering a few well-defined climate-related processes and using site understanding on local properties and processes, it is possible to reduce the uncertainties in future landscape developments for a specific site. Uncertainties include the abundance and distribution of ecosystems and associated properties related to processes governing the transport of matter. I conclude that relevant examples of historical and future landscape evolution for specific sites can be given that are useful for long-term assessments.

Une approche modélisante du potentiel TSL le long des plages du golfe du Lion est proposée sur la base du modèle d'ingénierie côtière Unibest-LT (Deltares). Sont exploités en entrée de modèle des données de houle de 1979 à 2010 (base de données ANEMOC-2 produite par le Cerema à partir d'une approche modélisante également) conjointement à des données topo-bathymétriques haute résolution LiDAR (base de données Litto3D produite conjointement par le SHOM et l'IGN). Le potentiel de TSL annuel est calculé pour 157 profils topo-bathymétriques couvrant l'ensemble des ∿250 km de littoral étudié dans ce travail de thèse.En premier lieu, le potentiel de TSL annuel résultant est d'abord estimé sur la base d'une année de houle type, établie à partir de 31 ans de houle horaire entre 1979 et 2010, puis pour chaque année entre 1979 et 2010. La différence observée avec le potentiel de TSL annuel résultat « type » permet de discrétiser les années en trois situations : anomalie positive, anomalie négative ou proche de la normale. Par ailleurs, un lien est clairement établi entre la variabilité interannuelle identifiée dans les simulations et les tempêtes. En outre, cette analyse interannuelle menée à l'échelle des plages du golfe du Lion amène à affiner les limites des cellules de dérive littorale potentielle, pour lesquelles trois scénarios d'organisation sont établis : habituel, occasionnel, exceptionnel.Enfin, le lien entre potentiel de TSL annuel résultant et variations du rivage est testé, conformément au large corpus bibliographique qui existe à ce sujet en ingénierie côtière. Cependant, les résultats s'avèrent décevants : une remise en cause de la théorie sous-jacente est proposée.
Wave data from 1979 to 2010 derived from a large-scale modelling database (ANEMOC-2) were used together with high resolution topo-bathymetric LiDAR data as inputs within the coastal engineering model Unibest-LT (Uniform Beach Sediment - Longshore Transport). The spatial and temporal coverage of these data offers a unique opportunity to carry out a comprehensive study of potential longshore transport intensity and direction.Over the 250 km-long stretch of coast covering the study area, the longshore drift directions computed with the 30-year mean wave climate closely match those of previous findings based on experimental geomorphological methods.Potential LST rates are then computed for each year individually over the 1979-2010 period. Deviations from the 30-year mean LST rates are used to identify 3 cases: positive anomalies, negative anomalies and close to normal. Storm contributions to longshore transport are brought into light: inter-annual variability in LST rates is strongly correlated to >4 m waves occurences.The relationship between LST rates gradients alongshore and shoreline changes is also investigated : despite the significant amout of papers on that subject, results showned in this thesis appears to be disappointing.In the light of these findings, coastal drift cell boundaries are defined taking into account the 30-year mean potential…

The coastlines of the world are the focus of population growth and urban development this century. It is projected that approximately 2.65 billion people will be living within the coastal zone by 2025. More than half of all Americans now live on or close to the coast with population density expected to increase. Within the Pacific Basin, population growth can increase the economic incentive to develop more land. On islands, this results in development pressures along the shoreline and into the active beach system. Chronic erosion of the shoreline increases resource and population vulnerability to inundation by storm surge, tsunami, and sea-level rise. As population increases along the coastline, the need to understand the highly dynamic coastal region becomes more important. The majority of shoreline change studies have been prompted by realization that coastal erosion threatens private property, public infrastructure, and natural ecosystems (National Academy Study, 1990). Improved understanding of detailed erosion patterns provides managers with a basis for planning appropriate coastal development and resource management, thus improving community resiliency and sustainability. Lack of robust physical processes modeling means that analysis of historical shoreline trends provides a practical, relatively affordable method of predicting future erosion hazards (National Academy Study, 1990). Typically, studies compile and analyze historic and modern shoreline position data to inform planning and policy about past shoreline variability. The methods used are designed to record, analyze, and predict patterns of shoreline change. These are largely dictated by the physical characteristics of the shoreline being studied and the type and quantity of shoreline position data available.

▼ My doctoral work stems from an original motivation to understand more closely why some areas of sandy coastlines erode and others accrete<—>an intriguing fundamental question and one of societal relevance wherever human coastal infrastructure exists. What are the physical processes driving shoreline change, and over what spatial and temporal scales are they manifest? If forces driving the littoral system change, how does the shoreline respond? Can we attribute observed patterns of shoreline change to a particular process? Recent novel numerical shoreline-evolution modeling demonstrated that wave-driven gradients in alongshore sediment transport could produce self-organized, emergent features on spatial scales from sand waves to large-scale capes [Ashton et al., 2001], introducing a new theoretical perspective to the cross-shore-oriented considerations of the coastal scientific community. The unexpected model results inspired fresh hypotheses about shoreline pattern formation and the forcing mechanisms behind them. One overarching hypothesis was that under regimes of high- and low-angle deep-water incident waves, alongshore shoreline perturbations grow or diffuse away, respectively. To test the hypothesis we looked for a correlation between shoreline curvature (showing perturbations to a nearly straight coastline) and shoreline change in observed measurements. High-resolution topographic lidar surveys of the North Carolina Outer Banks from 1996<–>2006 allowed robust, quantitative comparisons between shoreline surveys spanning tens of kms. In Chapter 1 [Lazarus and Murray, 2007] we report that over the last decade, at multi-km scales along the barrier islands, convex-seaward promontories tended to erode and concave-seaward embayments accrete<—>a pattern of diffusion consistent with the smoothing effects of alongshore-transport gradients driven by a low-angle wave climate. Why then, after a decade or more of smoothing, do plan-view bumps in the shoreline still persist? In Chapter 2 [Lazarus et al., in review] we compile evidence suggesting that (a) a framework of paleochannels may control the areas of persistent multi-km-scale shoreline convexity that (b) in turn drive decadal-term transient changes in shoreline morphology by (c) affecting gradients in wave-driven alongshore sediment transport. In Chapter 3, a third investigation of large-scale coastal behavior, we explore an existing premise that shoreline change on a sandy coast is a self-affine signal wherein patterns of changes are scale-invariant, perhaps suggesting that a single process operates across the scales. Applying wavelet analysis<—>a mathematical technique involving scaled filter transforms<—>we confirm that a power law fits the average variance of shoreline change at alongshore scales spanning approximately three orders of magnitude (5<–>5000 m). The power law itself does not necessarily indicate a single dominant driver; beach changes across those scales likely result from a… Advisors/Committee Members: Murray, A. Brad (advisor).

▼ Deficiencies exist in the study of shoreline dynamics of Georgia's barrier islands and the processes that influence change. Previously unexamined shoreline localities that were difficult to assess using existing techniques and software programs provide a basis for the development of new tools and methods for analyzing change. AMBUR (Analyzing Moving Boundaries Using R) was developed to analyze shoreline change along barrier islands with complex shapes and highly curved coastlines. Built using the R programming environment, AMBUR provides a suite of functions for quantifying the rate and magnitude of shoreline movement and performs additional statistical, graphical, and geospatial analyses. The reliability of transect-based analyses is improved using new techniques for curved shorelines too problematic for the traditional perpendicular-transect method. Application of AMBUR to Georgia's barrier islands provides a robust dataset for island-wide shoreline change and assists with classifying the modern behavior of the coast. Historical shorelines from 1855 to 2004 were analyzed and partitioned into oceanfront, backbarrier, and inlet-facing zones. Throughout the 1855 to 2004 era, 41 % of Georgia's oceanfront shoreline eroded at a mean rate of -1.66 m/yr EPR (± 0.06 m/yr) and the remaining shoreline accreted at 2.25 m/yr EPR (± 0.06 m/yr). The backbarrier eroded along 65 % of the shore at a mean rate of -0.35 m/yr EPR (± 0.07 m/yr) throughout the period. More than half of the islands exhibit a net seaward shift in area and regressive behavior, whereas Wolf and St. Catherines Islands are thinning and shortening and are transgressive, erosional hotspots. Reversals of longshore transport currents, primarily due to inlet dynamics and seasonal shifts in climate regimes, promote periods of accretion and erosion along the northern and southern ends of some islands. Stable, migrating, and ephemeral inlet processes at the local level exert the greatest influence over oceanfront shorelines. Backbarrier shorelines are primarily influenced by tidal creek migration, proximity to inlets and confluences of other streams. Human activities are influencing shoreline erosion and accretion rates through uses of hard/soft stabilization and dredging activities.

▼ There is a strong relationship between regional sediment transport and the local processes at tidal inlets and around coastal structures. Many coastal projects require quantitative understanding of these processes and the interactions between them. Regional sediment transport and shoreline evolution models that fully include important coastal processes at local scale are lacking at present. The overall aim of this thesis is to develop a new numerical model of regional sediment transport and shoreline evolution for complex conditions with a simulation domain that may extend over hundreds of kilometers and cover several inlets and river mouths including development of flood shoal and ebb shoal complexes, shoreline response in the vicinity of inlets, barrier elongation and different shore protection measures. The new numerical modeling tool is composed of a one-line model of shoreline change, an inlet reservoir model, and a spit growth model. The shoreline change model was based on the one-line theory (Pelnard-Considere, 1956), employing algorithms for the numerical solution developed by Hanson (1987) and including regional shoreline features introduced by Larson et al. (2002a). The inlet reservoir model is based on a reservoir analogy approach developed by Kraus (2000, 2002) and then refined by Larson et al. (2006) through the introduction of the flood shoal and associated coupling coefficients describing the transfer of sediment between the morphological units. A mathematical model of spit growth and barrier elognation supplied by sediment coming from the longshore sediment transport (LST) was developed based on the spit growth model suggested by Kraus (1999). In order to realistically reproduce the coastal evolution at local scales, an attempt was made in this study through the introduction of several new methods and modifications to improve the above mentioned models. Fine grain size sediment lost into the deep water was included in the shoreline change model through a loss parameter combined with gradients in the LST rate (Donnelly et al. 2004). Wave sheltering effects from the bars was included in the empirical formula for LST through an attenuation parameter for breaking wave height in lee of the bars. Direction of ebb jet at inlets was taken into account in the empirical formulas for the distances from the inlet to the downdrift and updrift attachment bars. Onshore movement of sediment from attachment bars was also included in the inlet reservoir model. For the spit growth and barrier elongation model, a relationship between maximum depth of the channel and the depth of active LST was used to estimate LST rate bypassing the spit. The model was validated against measurements at Hai Hau beach in Vietnam, at Long Island coast in the United States, and at the Badreveln spit in Sweden. At the Hai Hau beach, a 20-year time series of offshore waves hindcasted from the recorded wind data was used to reproduce the nearshore wave climate; measured shorelines in 1910, 1965, and 2000 were employed to calibrate and validate…

All model simulations agree that the temperature in Greece will increase in the range of 1°C to 2°C by the year 2030. In general, mean sea level in Mediterranean is expected to rise at the rate of 5 cm/decade. In particular, sea level will rise about 50cm by the year 2100 (with an uncertainty range of 20-86cm). Delta Nile, Venice and Thessaloniki appear to be the more sensitive areas in Mediterranean. The scope of the current dissertation is the estimation of the future coastline displacements, according to specific, climate change scenarios. The final, expected outcome would be the creation and use of a model, able to determine the future evolution of the shoreline. In order to achieve that, statistical and non-statistical methods were used in order to compute the shoreline change rate of 10 coastal areas of Greece. Furthermore, in the same 10 areas, the known mathematical filter Kalman was originally adjusted and tested using coastal data (shoreline positions), for the first time in this particular dissertation. The change rates that are calculated through the use of the Kalman filter combined with the statistical method of the OLS, constitute the best possible estimation with the lowest uncertainties of the future shoreline positions in all 10 coastal areas of the study. Furthermore, the application of the Binning method in every one of the 10 coastal areas of the study offered the opportunity to calculate partial change rates for certain sub-areas of each shoreline. That way, these sub-areas with similar statistical "behavior" were grouped and points on every shore were identified where the general trend of accretion or recession changes. With the use of the Binning method and the grouping of neighboring sections along the coastline it is easier to build a more precise and detailed profile for each shoreline. Consequently, costal planning can be organized with greater effectiveness regarding protection strategies, with priority to parts of each coast where the greater land losses are estimated by the prediction models. In conclusion, reliable shoreline change rates calculated by the mathematical models (such as the modified Kalman filter algorithm), combined with the advantages of the Binning method, constitute a rather complete and useful mechanism of studying coastal dynamics and shoreline evolution that was tested in the 10 Greek coastal areas of the current dissertation.

▼ Eastern North Carolina has over 300 km of barrier islands that comprise the Outer Banks and act as an important buffer from the Atlantic Ocean and boundary to the Albemarle-Pamlico Estuarine System. These islands also draw millions of visitors and dollars to the state every year. With sea-level rise and the persistence of extratropical and tropical storms, it is critical to examine the recent decadal response to storm events and geologic evolution in order to best prepare for future change. In this study, multiple methods were used to evaluate the recent decadal evolution of Ocracoke Island, NC. Shoreline change rates were calculated using a transect-based approach with imagery from 1949, 1974 and 2006. Other aerial imagery time steps were used to look at the spatial impact of historic storms and to select coring and trenching sites based on visible depositional history. The stratigraphic and sedimentological signature of recent and historic storm events was interpreted using seven vibracores and 32 trench excavations. Additionally, LiDAR data was used to assess morphologic change and to test a storm-impact scale based on storm surge, waves and maximum foredune height.  The average long-term shoreline change rate for all of Ocracoke Island was determined to be - 0.54 m/yr. The majority of the island has been eroding (over 65% of transects), and the average erosion rate was greatest in the most recent period analyzed (1974-2006). The shoreline change rates highlight the narrowing of the island through time. In some regions island width has decreased by as much as 70% (180 m).	  Hurricane Isabel (2003) overwashed a total of 9% of the island area with an average thickness of 0.24 m. The storm-impact scale showed a quantitative relationship between overwash and pre-existing dune conditions along the coast. Sedimentation from Isabel represented up to 26% of total backbarrier subaerial volume and was comparable to dune volume loss. Isabel caused up to 40 m of sound-directed migration of the foredune and substantial oceanside erosion, representing more than 20% of long-term net change in some regions of the island.   Four other distinct storm deposits were interpreted within the cores based on the sedimentological signatures of moderately to well-sorted fine to medium grained sand, coarse shell hash bases, and heavy mineral laminae. However, few cores had multiple deposits, indicating stacked overwash deposits are spatially and temporally variable. This collection of results shows the complexity of barrier island evolution and the necessity to examine soundward migration in three dimensions.  Advisors/Committee Members: Walsh, J. P.

▼ The inner continental shelf off the western half of the barrier island Fire Island, NY, is characterized by a series of obliquely oriented shoreface-connected ridges. The long-term historic shoreline record shows persistent undulations in shoreline shape at an alongshore scale similar to the alongshore scale of the ridges. This suggests that the ridges affect the wave transformation, alongshore sediment transport and corresponding shoreline change. These processes are investigated by utilizing the SWAN (Simulating WAves Nearshore) model, forced with realistic wave parameters, on a simplified, synthetic bathymetry replicating the scales of the shoreface-connected ridges. Results indicate that the relative magnitude of alongshore variations of modeled waves, alongshore transport, and the corresponding shoreline change are highly correlated with the relative orientation of the incoming waves to the ridges. Alongshore variations in both wave height and direction along the breaker line are much stronger when the predominant wave direction is along the main axis of the ridges rather than perpendicular to the ridge crests. This pattern of wave height variation is further explained by evaluating the directional energy spectrum and using a reverse ray-tracing technique. The gradients of the alongshore sediment transport, which lead to shoreline change, also appear to be stronger for waves with an angle of incidence similar to the ridge orientation. These results help explain the relationship between the oblique shoreface-connected ridges and the corresponding shoreline changes and shed light on the connection between the inner-shelf ridges and persistent shoreline undulations for the Western portion of Fire Island.
