This study area presents the geophysical and hydrogeomorphological research done to explore for groundwater in certain regions of the Brahmanavellamla watershed in Telangana State, India’s Nalgonda Mandal. The study’s goal was to evaluate the subsurface features and locate prospective groundwater resources in order to alleviate the region’s problems with water scarcity. Hydrogeological structures and underlying lithological differences were identified by means of geophysical surveys, which included Vertical Electrical Sounding (VES). In order to interpret lithological boundaries, define aquifer zones, and evaluate groundwater potential, the resistivity measurements that were acquired were evaluated. Hydrogeomorphological investigation was carried out concurrently to comprehend the impact of surface features on the occurrence and transport of groundwater. Insights into the subsurface hydrogeological environment and the identification of suitable areas for groundwater research were made possible by the integration of geophysical and hydrogeomorphological data. The results of this study provide important direction for water resource planning and development projects in the area, assisting in the sustainable management and usage of groundwater resources in the Brahmanavellamla watershed. The study of subsurface formations in order to get a better understanding of the hydrologic cycle, groundwater quality, and type of aquifers was important for groundwater exploration. There are several methods for exploring groundwater. The surface geophysical technique, namely electrical resistivity is one of the widely used techniques for groundwater exploration. Vertical Electrical Sounding (VES) is a technique that can provide valuable information about the vertical successions of subsurface geo-substances in terms of individual thicknesses and resistivity values. It is a helpful instrument for groundwater examination since it determines aquifer thickness in a particular area quickly and accurately. The purpose of this inquiry was to locate twenty well-site locations for water delivery functions utilizing surface geophysical techniques. However, hydrogeological and geological investigations were also included in addition to geophysical surveying efforts to improve the research. The resistivity values were compared with the hydrogeology and geomorphology of the area and suggested a few locations for drilling of bore wells in the area. This comparative study will be helpful to the local authorities for drilling of more bore wells to mitigate the water demand in the area.
