The main objectives of this paper are to assess the hydrogeological characteristics and evaluate the groundwater potentialities in Darasalam area, North Darfur State. Most data on geomorphology, meteorology, hydrology, hydrogeology, geology and GIS techniques were discussed and applied. Superficial deposits, Cretaceous sedimentary rocks intercalated with basaltic extrusive at Shagra basin underlain by undifferentiated basement complex constitute the common geologic units. Three aquifer types were determined include Quaternary superficial and wadifill deposits, Cretaceous Sedimentary aquifer; and fractured basement aquifer. Hantush and Neuman pumping test methods were used to measure the aquifer properties. The regional groundwater flow direction is generally from northeast towards southwest with few exceptions. The maximum hydraulic conductivity and transmissivity in leaky aquifers using Hantush method was found to be 9.306 and 104.98 m2/d respectively. The maximum hydraulic conductivity and transmissivity in unconfined Cretaceous Sedimentary aquifer was found to be 5.306 m/d and 95.472 m2/ drespectively using Neuman method in Daralasalam area. Evapotranspiration was estimated to be 85% where the average rainfall was less than 300 mm/year. The annual ground water recharge in the study area was estimated to be 703 × 1012 m3. The annual abstraction rate was calculated to be 11 x 106 m3 and the subsurface outflow was calculated to be 24×106 m3. The total groundwater storage of Darasalam zones were calculated to be 354.13 x 109 m3 in the study area. |
