- The spatial pattern of soil erosion and deposition on catchment scale are predicted by the GeoWEPP model in a small catchment of the Sichuan Hilly Basin. The estimated sediment delivery per unit area and sediment delivery ratio are 2760 t km2 yr-1 and 0.485, respectively. Compared with the results derived by the second soil erosion survey based on remote sensing, the results by the GeoWEPP model are reasonable. According to the spatial pattern of sediments simulated by the GeoWEPP, the slight soil erosion rates for the wood land and patter show that the woodland have good soil and water conservation benefit than cultivated slopes. In the same time, the GeoWEPP are useful tool to establish effective policy for comprehensive treatment of small catchment in view of the soil erosion and deposition could be estimated on time-scale and spatial-scale by the GeoWEPP.
