Hydrology Tool Set (HTS) includes a suite of tools that have been developed through a collaborative research effort of Canadian Rivers Institute (CRI), University of New Brunswick (UNB), Agriculture and Agri-Food Canada (AAFC) and Environment and Climate Change Canada (ECCC). The suite of hydrology tools have been developed as part of a larger research effort aimed at evaluating the impacts of agricultural production practices on groundwater and surface water quality and on the quality of downgradient aquatic ecosystems.
The various tools included in the suite can be used for advancing the understanding of local and watershed scale hydrology, such as stream hydrograph separation, water balance (e.g. evapotranspiration, drainage, infiltration, aquifer storage, etc.), soil moisture dynamics, crop water deficit and excess, crop irrigation requirements, etc. The tools included in the suite can be used in many areas of environmental research, such as the assessment of the impact of agricultural practices, urbanization, climate change etc. on surface water and groundwater.
All the tools included in HTS have been developed using several principles as follows:
ETCalc is a tool that integrates several customizable methods for calculating daily Potential Evapotranspiration (PET), Reference Evapotranspiration (ETR) and Actual Evapotranspiration (ET) based on user provided meteorological data and crop coefficients. The tool provides various output and data visualization options through a user-friendly interface and a streamlined process.
SepHydro is a tool that offers several customizable filtering algorithms for performing hydrograph separation (or baseflow separation) and assessing surface runoff and groundwater contributions to streamflow based on user provided daily streamflow data. The tool provides various output and data visualization options through a user-friendly interface and a streamlined process.
SWIB (Soil Water Stress, Irrigation Requirement and Water Balance) is a tool that allows users to estimate daily crop water stress (either as water deficit or water excess), crop irrigation requirements and the impact of irrigation on aquifer storage, as well as a series of water balance components, based on daily measured soil moisture and precipitation. The tool provides various output and data visualization options through a module-based user-friendly interface.
