| ABSTRACT Estimating the physical properties of water-bearing layers is an essential part of groundwater studies. One of the most effective ways of determining these properties is to conduct and analyze aquifer tests. The aim of this research is to carry out hydrogeological investigation in Khanaqin basin within Diyala Governorate in the east of Iraq to calculate hydraulic parameters of the most important product groundwater aquifers. Cooper-Jacob and Theis Recovery test methods were used to calculate transmissivity and storage coefficient after field investigation of aquifers extended in the basin. The geographical position, elevations, static water levels, depths, thicknesses and maximum yields were carried out during field work. The results showed that Khanaqin basin has two geological units represented by unconfined and confined aquifers, where (4) wells were used in pumping test. The average transmissivity parameter was ranged between (273-4590 m 2 /day) in unconfined aquifer while this range was (14.47-244.35 m 2 /day) in confined aquifer. Transmissivity contour map indicated increasing value of this parameter towards northern west direction of the Khanaqin basin. Storage coefficient ranged between (3.5*10-5 ) to (1.14*10-3 ). The increasing of transmissivity parameter as groundwater movement generally flow towards the northern west leading to increase groundwater discharge from wells penetrate unconfined and confined aquifers | ||
