Abstract:

The geo-electrical and Geographic Information System (GIS) techniques have been employed for modeling surface and groundwater bodies of the Kotli city and its surrounding areas in the District Kotli, Azad Jammu and Kashmir, Pakistan. The Landsat 8 imagery is used for modeling the surface water and Vertical Electrical Sounding (VES) method is applied for the delineation of subsurface lithology in the study area. A total number of 21 VES points have been collected by using Schlumberger configuration. The VES data was collected using ABEM Terrameter SAS 4000. The acquired data have been processed by using IPI2WIN (2008) software and the interpretation was carried out in terms of true resistivity and thickness of different layers of sedimentary strata. The groundwater potential zones (good and moderate) have been identified in the area. The thickness of aquifer varies from 20 m to 129 m. Most of aquifers are confined and of “A” (?1 < ?2 < ?3), “K” (?1 < ?2 > ?3) and “H” type (?1 > ?2 < ?3). The VES 1, 2, 10, 11, 12, 20 and 21 south western part of the study area showed poor to weak overburden protective capacity of the aquifers, hence are vulnerable to infiltrating fluids from storage facility or dumps.
