SCIMAP is being used in the Defra funded River Eden Demonstration Test Catchment (EdenDTC) project. This project is investigating the dynamics of water quality from agricultural land using state of the art, real time, water quality monitoring to gain new insights. This new insight will then be used to design mitigation measures to reduce the [...]
Durham Wildlife Trust is using SCIMAP to identify areas with high fine sediment pollution risk within the River Wear catchment. The trust exists to protect wildlife and is therefore committed to tackling the problems that excess fine sediment cause in aquatic ecosystems; problems such as increased turbidity, reduced visibility and the smothering of the channel [...]
Understanding nutrient connectivity at the landscape scale: The use of the SCIMAP approach in the UK and Ireland.
You can download the 2011 version of SCIMAP for non-commercial use under a Creative Commons license. This version has the SCIMAP-Forward based calculations for fine sediment predictions, a method to buffer your catchment to prevent no-data leaking into you area of interest and the network index landscape scale connectivity calculations. If you want to use [...]

Within SCIMAP, the hydrological connectivity is based on the ‘Network Index’ (Lane et al. 2004). This index calculates the level of landscape wetness for each point to both generate runoff and for there to be a continuous flowpath to the river or lake. In many applications of SCIMAP, the topographic wetness index is used to [...]
