  • Beschreibung: This study demonstrates an application of resistivity surveys to understand local hydrological conditionsand basement configuration in Kirana Hills region of District Chiniot. Schlumberger configuration has been applied toacquire vertical electrical sounding (VES) data. The apparent resistivity curves were calibrated with theoretical curvesto compute true resistivity and depth of different layers. Maps of true resistivity at various depths were generated tostudy the lateral resistivity variation in the area. VES sounding data were compared with available lithological columnsto establish relationship of lithology and resistivity. Resistivity values are laterally variable due to lithology and qualityof water. Very low resistivity values were observed within alluvial sediments close to the Kirana Hills due to presenceof high Total Dissolved Solids in water. Resistivity value layers in unconsolidated sediments increases in the southernand western parts of the area where relatively better quality of groundwater occurs. In the northern and eastern parts ofthe study area very high resistivity (greater than 100 Ωm) is recorded at depth greater than 40m that indicates hard rockbasement. The resistivity survey in the area is useful to differentiate zones of low and high Total Dissolved Solidsgroundwater and also determine the zones where subsurface basement is shallow. Therefore, resistivity survey inKirana Hill regions is helpful in solving hydrological issues of the study area.
