The Eshtehard Plain in Tehran Province, Iran has been investigated by Vertical Electrical Soundings (VES) using the Schlumberger array in order to determine the aquifer characteristics and groundwater potential of the subsurface layers. The main goals of this survey were to determine the aquifer parameters such as thickness, depth, aquifer type and boundaries and high yield potential zones. For those purposes 65 VES's with maximum 1000 m current electrode separation were conducted within the area. Four main geo-electrical layers were identified by correlation of interpreted VES data with some existing boreholes. The results were presented in the form of resistivity, aquifer thickness and Transverse Resistance (RT) maps. According to, the thickness map, average thickness of the alluvial aquifer ranges between 50 and 175 m. The zones with maximum transverse resistance (1000-2000 ohm m2) in south of Eshtehard city and west of the plain represent the areas with highest degree of quality and quantity of groundwater. © Medwell Journals, 2019.
