English Abstract
The focus of this study was to conduct runoff estimation in Gedaref State based on rainfall storm values as a first step in rainfall harvesting and to enable proper planning and management of available resources, that the management of surface water resources is an important step towards water scarcity resolution.
Towards this purpose, the study objectives were set to carryout the task of characterizing the hydrological system at Gedarif basin and some of its catchments using Arc Gis tool.
The study is based on the available data in Gedarif Metrological Station, the Wadi Admin of Ministry of Ministry of Irrigation, USGS and (SKAP) map album.
The data processing and analysis were done in GIS environment.
For the extraction of the watersheds characteristics and the subsequent prediction of its runoff depths, the study relied mainly on the use of models as the most feasible approach.
SCS-CN method was used in GIS environment to estimate runoff depths and volumes and maintain their spatial location and simulate the real flow system in the Gedaref state and some of its watersheds using soil, land use and hydrologic condition data.
Rainfall analysis was done ; June to October is the main rainy season.
July-August are considered to be wettest two months of the year where about 70 % of the rain falls within these two months The average annual rainfall of Gedarif is 586 mm, the mean aerial precipitation is 567 and The estimated runoff depths vary between 199mm and 575mm.
The analysis found that, Khor Abu Fargha’s maximum runoff depth is 556mm, Rawashda 543mm and Ghamida 550mm.
Minimum runoff estimated is 481mm at Abu Fargha, 463mm at Rawashda and 384mm at Wadi Abu Ghamida.
The study of Gedaref State basins revealed the potentiality of the area for rainfall water harvesting, that the Surface water is normally available in large amount during the rainy season, but is scarce in the dry season.
