Abstract

To complement the Inabanga Watershed Project (BSWM, 2005), the study reported here was conducted to assess erosion and water resources degradation focussed on the Upper Inabanga Watershed using the Water Erosion Prediction Project (WEPP) erosion model and geographic information system and GIS tools. The study was divided into two sections. The first section was the assessment of the impact of land uses and farm management practices using five runoff experimental plots and two watersheds. The second section of the study was an application of the WEPP and GeoWEPP erosion models. Except for most of the crop management parameters, local climate, soil and topographic parameters were determined and used as inputs to run the model. The WEPP-GeoWEPP watershed simulations predicted that any increase in agricultural areas increased on-site soil loss and sediment yield from the watershed.
