Abstract|ملخص البحث

The purpose of this paper is to investigate and evaluate the groundwater in the Um Ruwaba aquifer by using new methods and evidence for pumping tests. The geological units of the area are divided mainly into basement complex and sedimentary cover. The basement complex (Precambrian age) consists of metasediments, gneisses, schist and quartzites, and these units have been intruded by granites. The cover consists of sediments of the Um Ruwaba formation (Tertiary to Quaternary age) resting unconformably on the basement. On the surface of these sediments rest superficial deposits which are believed to be of recent age. The hydrogeological studies are mainly concerned with the Um Ruwaba aquifer in the study area. The results of pumping test revealed the wide variation in hydraulic properties depending on geological formation. The paper is obtained the new patented derived from Elhag (2014), which is able to calculate the value of storativity. Where, the aquifer is characterized by low coefficient of transmissibility values, which the average varying from 4.5 to 333 m2 /d, and the average coefficient of storage values ranging between 1.6×10-4 and 8.1×10-3.
