ABSTRACT
The model EROSION 3D was developed with the intention to create an easy-to-use tool for erosion prediction in soil and water conservation planning and assessment. EROSION 3D model has been applied in different parts of the world to test its applicability under different hydrological conditions. Since the model operates on a grid-cell basis EROSION 3D allows generating drainage paths by which water and sediment can be routed from the top to the bottom of the respective catchment. The equation developed on the basis of extensive erosion data describes the average annual erosion as a function of various empirically determined factors with which the influences of climate, soil and agriculture on erosion are mapped. The comparison showed that simulated soil loss was generally too high which can be due to weak input data. It implied that the input data required for the simulation of soil erosion should be of good quality.
