Hydraulic Characteristics of the Dammam Aquifer in Al-Rahba Area, Najaf, Western Iraq

The present study seeks to evaluate the hydraulic properties of the aquifer strata. In the absence of observation wells adjacent to the pumping wells, four wells in the research area (P.W1, P.W2, P.W3, and P.W4) were utilized for the single pumping test experiment, employing the Cooper-Jacob and Theis Recovery methodologies as a basis. The transmissivity values of the aquifer in the studied area varied from 0.43 to 1198.61 m²/day. The specific capacity values varied from 1.60 to 3811.76 m²/day, while the hydraulic conductivity ranged from 0.01 to 19.83 m/day. Clay in the aquifer accounts for the substantial difference in values of W.P4. Both transmissivity and hydraulic conductivity are markedly low.
