Degraded water quality and floodwaters pose a significant threat to both people and ecology. Both of these pressures are from diffuse sources across the landscape that are concentrated into problems in rivers, lakes and the sea. SCIMAP provides a framework to consider where in the landscape these pressures are coming from and hence where mitigation actions would be most effective. SCIMAP works by identifying where there is a significant source of the pressure, related to attributes such as land cover, topographic position and ground slope gradient, and the connectivity, which is the ease with which material can make it to the channel. The SCIMAP framework considers four environmental pressures: 1. sediment, 2. nutrients (N and P), 3. microbial pollution (FIOs such as E. coli) and 4. flood hazard generation.
On this website, we provide a basic description of the science base that we are developing, we illustrate the SCIMAP approach and how it works, and we provide material for further learning about the approach. You can download the SCIMAP software for Windows or use the web-based my.scimap tool.
SCIMAP FINE SEDIMENT
DESKTOP SOFTWARE FOR WINDOWS
The Windows desktop version of SCIMAP for fine sediment is embedded within a custom build of SAGA GIS
my.SCIMAP, allows for the simple creation and export of sediment risk maps using a web-based version of SCIMAP.
SOURCE MAPPING FOR FIOS
fio.SCIMAP is the web-based version of the source mapping for faecal indicator organisms.
SPATIAL TARGETTING OF NFM MEASURES.
Identifying locations for the placement of natural flood risk management mitigation features, such as storage ponds, flow slowing debris dams and land-use change. Coming soon.
