Identification of Potential Runoff Harvesting Sites in Wadi Elrawakeeb-Alsayal Watershed

Abstract

To identify the suitable areas for potential runoff harvesting in Wadi Elrawakeeb and Wadi Alsayal desertified watershed, spatial suitability analysis was applied considering three major factors; potential surface runoff, inhabited sites, sites planted with field crops, and two additional factors; sub-basins average runoff and outlet locations of sub-basins. Obtained results showed that; most, middle and least suitable areas for water harvesting in the studied watershed are located at the sub-basins outlets, which are formed by the longest flow paths of both Wadis.
