This study examines the groundwater potential in an arid desert region that has unpredictable drought conditions throughout the year. With the absence of surface water systems, the groundwater aquifer, recharged only by monsoon rains, serves as the source for drinking and daily water use. To evaluate the aquifer characteristics, 128 vertical electrical soundings (VES) were conducted using the Schlumberger electrode configuration. The measured geo-electrical parameters were analysed using Interpex IX1D software, and variations in layer thickness and electrical resistivity (ER) were mapped in an ArcGIS environment using the inverse distance weighted interpolation technique. The Dar-Zarrouk parameters and ER variations indicate the presence of both shallow and deep aquifers, with depth ranging from 60 m to 100 m, covering an area of approximately 760 km2. These aquifers possess a groundwater potential of about 260 billion cubic meters. The study demonstrates that integrating VES data with GIS effectively addresses the challenges in vulnerable regions and provides reliable results for quantifying groundwater potential.
