Description :
An integrated modelling approach (MIRSED) which utilizes the process-based soil erosion model WEPP (Water Erosion Prediction Project) is presented for the assessment of hillslope-scale soil erosion at 5 sites throughout England and Wales. These sites range in size from 48 to 66 km2 and contain a broad range of soil, slope and land-use combinations. Potential erosion is visualized demonstrating the variability that can occur in model output due to uncertainty and providing a tool with which to target areas of high hillslope erosion risk within a catchment or region, whilst still considering the limitations of such a modelling approach.
