عنوان المقالة:دراسة ارتفاع مناسيب المياه الجوفية في بعض احياء مدينة سامراء باستخدام تقنية المسح الكهربائي ثنائي البعدين Study of Groundwater Level in Samarra City by Using 2D Resistivity Imaging Technique
The study included applying 2D electric resistivity imaging in thirteen locations which had been identified based on primary geological and topographical information of the study area, as well as the availability extent of convenient areas and locations for survey work. Land survey were also performed to determine the elevation above sea level depending on tripling points available in the region; in addition to analyzing water samples to determine their chemical content.ABEM Terrameter LS was used for data collection, and field work was conducted in Samarra city. Wenner-Schlumberger array was applied to survey 2D linear sections by different distance between electrodes. The maximum penetrating depth was 74 meters. Two-dimensional data were analyzed and inversions by RES2DINV software. The results showed that the reasons behind the rise of groundwater levels in some locations without others are due to the existence of lenses or suspended water assemblages resulted from rain water and sewage leakage and not due to the effect of main aquifers in the region. Geoelectrical survey sections also showed the presence of dry layers and impermeable layers separating sub-surface water from the main aquifer in the region.
