Water Harvesting of the area North of Khartoum Bahri

Abstract

The purpose of this study is to solve the problem of rain water of the area north of the Khartoum Bahri and protect the Villages from the floods, and conduct a comprehensive hydrological study of the water basins passing through that area. The methods used in this study were to collect data from different sources such as Digital Elevation Maps, Urban development maps, Rainfall data. In addition to hydrological, hydro geological studies and survey works. These data were analyzed using hydraulics equations and probability distribution functions𝑓(𝑥). From the results the basins catchment drainage has been identified and planned based on hydrology, geological and topography of the area and it was found that the basins that produce the torrents, mostly located north east of the catchment, the area of these catchment is 11.5 km 2. The maximum out flow for catchment is about 138 m3/s in the central of catchment area, and is considered the best selected area for the construction of water harvesting technique. Normal distribution has been found to be the best fitted distribution for the representation of the annual rainfall in study area. Conclusion and recommendation drawn from this study is to Construct embankment or dike to prevent the water passing in the north-east direction of the study area.
