Description :
MEFIDIS (short for Physically Based Distributed Erosion Model) was developed to simulate the consequences of climate and land-use changes for surface runoff and erosion patterns during extreme rainfall events. The model relies on physically based runoff and soil detachment equations, dividing the simulation area into spatial homogeneous units and using a dynamic approach for runoff and suspended sediment distribution. It was evaluated with measured runoff and net erosion data for 16 events in the Lucky Hills 103 (USA) and Ganspoel (Belgium) catchments, using a single parameter set for each catchment and simple assumptions (wet or dry) on pre-storm soil moisture.
