Abstract A concept for the continuous modelling of erosion, solute and sediment transport at the catchment scale is presented. The simulation is based on the application of the OPUS model designed for single slopes. In order to apply the model at the catchment scale, the study area (54 km 2 ) is discretized into numerous slopes. The simulation results are compared with measurements at different spatial and temporal scales of a mesoscale catchment used for drinking water supply. Three small sub-catchments, ranging between 21 and 29 ha, are used to validate the model at the local scale. Process observations at this scale are used to modify the OPUS model. While fo...
