Description :
This study aims to develop a physically based model that incorporates all water erosion controlling processes in a Sahelian environment. The model is calibrated and tested with field data from the 2001 rainy season in the Katacheri catchment in northern Burkina Faso. It is concluded that the modified version of European Soil Erosion Model, EUROSEM, in PCRaster for the Sahel is a fully dynamic erosion model, able to simulate infiltration, runoff routing, pool formation, sediment transport, and erosion and deposition by inter-rill processes over the land surface in individual storms at the scale of both runoff plots and fields.
