The aim of this study is to the evaluation of the general hydrogeology condition of the Al-Khassa sub-basin area. Pumping test has been done for five wells in the area. The hydrogeological characteristics (transmissivity, hydraulic conductivity and storage coefficient) were determined in the area by input data which obtained from the pumping test process into the (AquiferWin32, Version 5) software program. The data were analyzed using Copper-Jacob, Theis and Hantuosh methods for pumping, the values of hydraulic characteristics range from: transmissivity (0.98 to 19.57) m²/day in (W7-W9-W10-W12) sites and 416 m²/day in W1, hydraulic conductivity (0.051 to 0.305) m/day in (W7-W9-W10-W12) sites and 5.012 m/day in W1, storage coefficient 0.021 to 0.065, intendment that the water is pumped from semi-confined aquifer. By using the lithological information, the saturated thickness of where the minimum thickness of 47 m is observed in site W4, and a maximum thickness of 83 m are obtained in site W1, with an average of 67 m. Groundwater flow was 0.364 MCM annually. The flow direction of groundwater was drawn by calculated head values of the eleven wells, it was from the recharge areas in northeast and southeast towards the discharging areas at west.
