| Abstract | ||
| The main objective of the research is to identify the hydrogeological characteristics of the Dammam confined aquifer by selecting carefully nine wells of suitable properties for carrying out the pumping test within study area. The study area is located in Karbala Governorate between longitudes (43˚ 47ʹ 58ʺE - 43˚ 59ʹ 45ʺE), and latitudes (32˚ 26ʹ 54ʺN - 32˚ 33ʹ 16ʺN).The study area has a trapezoidal shape covering an area of about (134.6) km2, which contains many geological formations and represents part of Karbala-Najaf plateau. The producing hydrogeological unit in the area is the Dammam aquifer. Type of this aquifer is karst confined aquifer. In this study, a pumping test was performed on November, 2012, at a wells on Karbala desert area then applying AQTESOLV software version 4.5 for pumping test analysis to determine wells hydraulics for the nine deep wells that partially penetrated the Dammam aquifer and distributed all over the studied area. The results indicate that the transmissivity value for the Dammam confined aquifer ranges from (26.19-4134.6) m2/day and the hydraulic conductivity value ranges from (0.44-45.94) m/day. | ||
