Salih صبار عبد الله صالح PY - 2013 VL - 5 IS - 1 SP - 81 EP - 100 JO - IRAQI JOURNAL OF DESERT STUDIES المجلة العراقية لدراسات الصحراء SN - 19947801 26649454 AB - The area of study located between (43° 53' 23") and (44° 17' 23") Longitudes and latitudes (34° 27' 19") and(34° 46' 20"),east of Tigris river and boarded by Hamrin Anticline from north, Al Khashib valley from east andShari Lake from south.The climate data which recorded from Tikrit station for the period (1988-2011); Theannual average of rainfall was 169 mm, also the average of evapotranspiration has been calculated according toThornthwaite which indicates a water surplus about 41.35%. According the parameters of water balance the areadivided into five zones (A,B,C,D,E). The recharge has been calculated in each parts depending on soil moistureand the surface runoff. The calculated recharge of the groundwater is about 37 m3/year.Lithological descriptionof wells, and hydraulic properties indicate two groundwater aquifers The shallow one located within Quaternarydeposits which is unconfined while the deeper aquifer is semi confined and located in Ingina formation.Thehydraulic properties of these aquifers calculated according to pumping test analysis, these are 1135.54m2/day,73.334 m/day and 0.0849 for transmissivity, hydraulic conductivity, and storage coefficient respectively.The flow direction of groundwater is radial from the center of sand dunes, and the main flow is to the directionof Tigris River and Shari lake depression.
