Further development of a simple erosion and sediment transport model for catchment management in African catchments

This research aims to address the issues of water quantity and quality. South Africa is a water-scarce country in need of more efficient water resource management. Efficient water resource management depends on information; this study seeks to provide information on the rates of sedimentation of South African reservoirs and river systems. The goal is to build a simple erosion and sediment transport model that can estimate erosion and sediment yield across multiple spatial and temporal scales. The tool (model) will be made freely available to catchment managers across the country, enabling them to quantify rates of sediment and thereby assisting them in the management of scarce water resources.
