Limitations of SCIMAP
The key limitation with an application of SCIMAP is the quality of the input data (garbage in, garbage out). Therefore, care must be taken to use datasets with the required level of spatial information. Many…
Where is SCIMAP applicable?
The standard implementation of the SCIMAP framework is applicable where the topographic controls dominate the movement of water and pollutants through the landscape. Therefore, SCIMAP is widely applicable in many parts of the UK. However,…
What are the scale and data requirements for SCIMAP?
SCIMAP can be run across large catchment (2000 km2 +) as well as for targeted sub-catchments (e.g. < 1km2). The normal grid resolution is 5m based on the NextMap DTM product therefore giving large coverage…
What is the scientific basis of SCIMAP?
SCIMAP is based on the identification of locations of critical source areas (Heathwaite et al. 2005). within the landscape. These locations are based on the areas that are most likely to have a source of…
How SCIMAP aids the spatial targeting of diffuse pollution mitigation measures
SCIMAP aids spatial targeting by identifying the locations in the landscape that are most likely to be contributing to an observed diffuse pollution issue. SCIMAP should be used as part of a toolkit whereby a…
Basic description of the SCIMAP framework
SCIMAP is a risk-mapping framework designed to identify where in the landscape diffuse pollution is most likely to be originating. SCIMAP does not try to make quantitative predictions in real world units (e.g. mg l-1)…
Diffuse Pollution, the Water Framework Directive and SCIMAP – an Environment Agency View
Linda Pope, Environment Agency The Water Framework Directive requires the Environment Agency assesses the ecological status of all waterbodies, determine the pressures which are causing waterbodies to not achieve good ecological status and put in…
