RESULTS ASSESSING THE POTENTIAL OF FLOODWATER HARVESTING IN SELEIT AREA WADIS, SUDAN- USING REMOTE SENSING AND GIS

This study focused on investigating the potential of floodwater harvesting from four ephemeral seasonal streams (wadis) in Seleit Area in the north of Khartoum State in Sudan. The area is subjected to severe flashfloods that resulted in huge damages in lives and properties. It aimed, in one hand, to estimate the potential runoff of the rainstorm events that could be impounded in some sites along the wadi course to prevent downstream population from the flash floods threats. And from the other hand, to site some locations that could be suitable to endue new environments for effective use of the floods water by practicing some kinds of irrigated agriculture or rangeland enhancement, as an example. GIS and Remote Sensing were used as assisting tools in calculating the watershed areas of the wadis and in assessing the potential sites for water harvesting systems
