Description :
The AA. present a topography based hillslope erosion and deposition model that is based on the WATEM/SEDEM model structure and works on a millennial time scale. Soil erosion, transport and deposition are calculated using slope and unit contributing area. The topography is iteratively rejuvenated by taking into account modelled erosion and deposition rates, thereby simulating topographic development backwards in time. The model is spatially evaluated, using detailed estimates for historical soil erosion and show that the model can simulate realistic soil redistribution patterns.
