AbstractIn Kordofan Province, ground water is obtained from the Nubian aquifer, the Umm Ruwaba aquifer, and the surficial aquifer. During the rainy season, additional water supplies are recovered from pools, streams and excavated ponds. The annual rainfall in the Province ranges from a high of approximately 900 mm. in the Nuba Mountain area to a low of less than 200 mm. in the northern desert regions. Although most of the precipitation is lost by evapotranspiration, a small percentage of the rainfall recharges the principal aquifers in the Province. The stream beds are the main source of infiltration. Because of the large extent of the area underlain by the principal aquifers, a small rate of recharge results in a large ground water increment,
