Hydrological Framework And Estimation Of Aquifer Hydraulic Parameters Using Geoelectrical Data; Vicinity Of Rawalpindi, Islamabad

Abstract

The main objective of this research is to carried out the Electrical resistivity survey in Islamabad different regions to determine the depth of water and to propose new well location to full fill the demands of protective fresh water aquifers. The methodology used for this procedure is Vertical Electrical Sounding using the Schlumberger configuration. The maximum spread is about 1m to 150m. According to our results, it is concluded that potential of groundwater zone in the study area exists at the depth greater than 36m. Dar Zarrouk parameters calculations used to find the aquifer properties and their capacity. VES-05, VES-07 and VES-08 have high longitudinal conductance values which makes them the highest priority in terms of groundwater. Based on the results of Transverse resistance at VES-02 and VES-04 shows the high transverse resistance values which indication of high transmissivity and have good groundwater potential. Combining these results, probable well location can be at VES-01, VES-04.
