Evaluation of Hydrogeological Conditions, of the groundwater reservoir west of Samarra by using Data pumping tests in wells Single

Abstract

Geologicall and hydrological evaluation have carried out (50) wells east of Samarra, Its study explained thate and two aquifers were distinguished; Injana as semi-confined aquifer and Quaternary sediments as unconfined aquifer. The study of the lithological section shows that the thickness of the sediments increases as we move to the south of the study area and decrease to the north. Of the movement and groundwater levels of (50) wells. It was shown that the direction of its movement is from west to east, with a slight slope towards the south, as well as studying the hydraulic properties of these wells determine by using the pumping test data in the individual wells to determine the values ​​of the Transmssivity (T), (51.8 m2/day) east of the study area, gradually decreasing to (5.3m2/day) west of the study area. The values ​​of the hydraulic conductivity (K) reached (1.23 m/day) east of the study area and gradually decreased to (0.119m/day) west of the study area.
