Description :
A model, the Tillage-Controlled Runoff Pattern model (TCRP model) was developed to create a runoff pattern with flow in the direction of the plough-lines for all tilled fields within a catchment. The model needs a digital elevation model (DEM), a landuse map and the major tillage orientation per tilled field as input. Runoff patterns created with the model could be used in any raster-based erosion model. The effect of the runoff pattern on simulated erosion patterns is shown for one field using the erosion model LISEM.
