Abstract

The Limburg Soil Erosion Model (LISEM) and the EROSION 3D model were applied to the Skuterud catchment in the Ås municipality, for which measured discharge data, at the outlet, was available. The goal of this study was to investigate how the differences of two physically based models will influence the result of one and the same problem, to give an in-depth insight of what are the sources of uncertainty in modelling processes. Special attention was given to the dependency of the model results on effects of grid cell size and time resolution. The grid cell size of the maps was easily adapted by using digital elevation models (DEM) obtained from airborne light detection and ranging (LIDAR) data. Furthermore the predicted erosion patterns were compared with an orthographic picture to validate the simulation results also in a spatial context. With both models, it was possible to simulate a satisfactory accurate hydrograph and total amount of surface discharge. However, the output maps produced by the models showed quite different erosion and deposition features
