Simulation of selected events on the Catsop catchment by KINEROS2: A report for the GCTE conference on catchment scale erosion models

Data from the Catsop catchment in South Limburg, Netherlands was simulated with the model KINEROS2. The results of calibration and validation on a split set of runoff and sediment data are reported and the variations in apparent parameters are analyzed. Calibration was performed with regard to the temporal distribution of runoff and sediment rather than single values such as total or peak rates. Based on the simulations, soil erodibility was considerably higher in 1993 than earlier years. Sediment discharge is quite sensitive to hydrologic simulation, as the amount and velocity of runoff affects sediment transport capacity which in turn determines the delivery of soil disturbed by rainsplash. Overall ability of the model to reproduce the measured data was considered relatively good.
