Degraded water quality and floodwaters pose a significant threat to both humans and the ecosystem. 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 for considering where these pressures originate in the landscape and, therefore, 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 reach 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 scientific foundation we are developing, explain the SCIMAP approach and how it works, and offer materials for further learning. You can use SCIMAP within SAGA-GIS, use the QGIS Plugin or use the web-based my.scimap tool.
SCIMAP FINE SEDIMENT
SCIMAP-Sediment is focused on the mobilisation and connectivity of sediment within catchments. More Details.
SCIMAP FLOOD
SPATIAL TARGETTING OF NFM MEASURES.
Identifying locations to place natural flood-risk management mitigation features, such as storage ponds, flow-slowing debris dams, and land-use changes. More details.
SCIMAP FIO
SOURCE MAPPING FOR FIOs
SCIMAP-FIO is the version of the source mapping for faecal indicator organisms. More details.
