Web-based SCIMAP
I would like to introduce the new my.scimap.org.uk web based version of the SCIMAP risk mapping approach. SCIMAP allows you to identify the source areas with a landscape that are most likely to be contributing…
Participatory Action Research in physical geography with SCIMAP
This is the journal paper that used SCIMAP to investigate the use of ‘Participatory Action Research’ to work with stakeholders in addressing environmental issues. “Going with the flow? Using participatory action research in physical geography.”…
Managing multiple non-point pressures on water quality and ecological habitat: Spatially targeting effective mitigation actions at the landscape scale
Sim Reaney, American Geophysical Union Fall Meeting 2014 Abstract Catchment systems deliver many benefits to society and ecology but also produce a range of undesirable externalities including flooding, diffuse pollution from agriculture, forestry and urban…
SCIMAP FIO
My name is Kenneth Porter and I am a first year NERC-funded PhD student. I’ll be working on my project “Risk-based modelling of pathogen export from agricultural catchments under a changing climate” for the next…
Expertise needed to run SCIMAP
Users need to understand the key hydrological processes within their area of interest and basic GIS skills. The user needs to understand what the results are saying and to ensure that the assumptions fit with…
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…
