Determine the groundwater aquifers in southwest of Samawah city, (Al Muthanna governorate)‎, southern Iraq, by using 2-d resistivity imaging survey

الملخص EN

The 2-D Resistivity imaging survey conducted within the desert area to meet the region's need of groundwater, due to the absence of any surface water, in addition, there are no any geophysical studies carried out previously.

Ten point survey was performed to study the ground water aquifers in the southwest of Samawah city, Iraq.

The length of the survey line in each point survey is 1200 meters by using 120 electrodes with 10 meters electrode spacing by applying Wenner-Schlumberger array.

There are three main resistivity zones in the study area.

The first resistivity zone ranging between 2.00-10.1 ohm.m, locate at shallow depth, represented Quaternary deposits.

The second resistivity zone ranging between 22.8-51.3 ohm.m, it represents bearing-groundwater zone, located within middle Dammam Formation.

The third resistivity zone was ranging between 115-584 ohm.m, it represents the impermeability zone of lower Dammam Formation.
