Abstract

This study was conducted to estimate the potential runoff coefficient (PRC) using geographic information system (GIS) based on the area's hydrologic soil group (HSG), land use, slope and determine the runoff volume. The soil map of Egypt was extracted from the soil map of the world and then was used in building a soil hydrological group map. Landsat image 5/7 TM/ETM was incorporated with land cover data to generate land use and land cover (LULC) map. Slope map for Egypt was generated from a 30 m DEM. The GIS technique was used to generate PRC map. Annual runoff depth is derived based on the annual rainfall surplus and runoff coefficient per pixel using raster calculator tool in ArcGIS. A variation from as low as 0 to a maximum of 180 mm was observed due to divergence in topography and climate in Egypt
