Abstract
The study area intendes for agricultural investment and establishment stations of water pumping for human use to the nearby areas, southwest of Samawah city. Twelve Two-Dimension (2-D) survey points were performed by using Wenner-Schlumberger array configuration to take the measurements. The inverse models of two survey point appear the effect of the saline groundwater that raises from Rus Formation, which caused a significant reduction in resistivity of the groundwater-bearing zone within middle Dammam Formation along the fault plane.
Highlights
IntroductionThe electrical survey considers the most important method used to definition and study of the groundwater aquifers [1]
The study area is located at south-west of Samawah city, locally called Shghatia (SH) as shown inIraqi Journal of Science, 2019, Vol 60, No.5, pp: 1095-1103 current flows through earth materials at shallow depth by two main methods [2, 4]
The survey area is characterized by existence the hills of fragments of limestone alternate with flat and depressions areas that filled by quaternary deposition [7, 9]
Summary
The electrical survey considers the most important method used to definition and study of the groundwater aquifers [1]. The fluctuation in chemical and physical weathering processes along the Quaternary period produced these features and structures of the earth’s surface, in addition, weakly of rainfall and absence of vegetation covers [10] These flat and depressions areas extend from many squire kilometers to several hundreds of square kilometers [10], which have important investment and agricultural purposes. B- Dammam Formation (Upper- Middle Eocene), which consider as one most important of groundwater-bearing zone in the southwest of Iraq [15]. It exposed in most of the survey area. After finishing of removal bad data, the field data being of high quality, which reflects the distribution of the subsurface resistivity [3]
