TY - JOUR ID - TI - Hydraulic Paramters Of Groundwater Aquifers In Khanaqin Basin AU - Hussein Ilaibi Zamil Al-Sudani PY - 2017 VL - 43 IS - 2A SP - 80 EP - 95 JO - Journal of Basrah Researches (Sciences) مجلة ابحاث البصرة ( العلميات) SN - 18172695 2411524X AB - ABSTRACT Estimating the physical properties of water-bearing layers is an essential part ofgroundwater studies. One of the most effective ways of determining these properties is toconduct and analyze aquifer tests. The aim of this research is to carry out hydrogeologicalinvestigation in Khanaqin basin within Diyala Governorate in the east of Iraq to calculatehydraulic parameters of the most important product groundwater aquifers. Cooper-Jacoband Theis Recovery test methods were used to calculate transmissivity and storagecoefficient after field investigation of aquifers extended in the basin. The geographicalposition, elevations, static water levels, depths, thicknesses and maximum yields werecarried out during field work. The results showed that Khanaqin basin has two geologicalunits represented by unconfined and confined aquifers, where (4) wells were used inpumping test. The average transmissivity parameter was ranged between (273-4590m2/day) in unconfined aquifer while this range was (14.47-244.35 m2/day) in confinedaquifer. Transmissivity contour map indicated increasing value of this parameter towardsnorthern 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 groundwatermovement generally flow towards the northern west leading to increase groundwaterdischarge from wells penetrate unconfined and confined aquifers
