Soil erosion and sediment transport modelling using hydrological models and remote sensing techniques in Wadi Billi, Egypt

Abstract Modelling soil erosion and sediment transport are vital to assess the impact of flash floods. However, limited research works have studied transport, especially in Egypt. This paper employs HEC-HMS lumped hydrological model predict load due flood event 9th March 2014 Wadi Billi, The Modified USLE has been used calculate total upland erosion, while Laursen-Copeland simulate streams’ potential. Normalized Difference Vegetation Index (NDVI) applied over Landsat 8 image captured on 20th February using ArcMap 10.5 determine vegetation cover based its spectral footprint. resulted sedigraph showed accumulation more than five thousand tons sediments at Wadi’s outlet. results crucial design a suitable stormwater management system protect downstream urban area use water for groundwater recharge.
