Tracing Deep-Seated Saturated Fractures in Depleted Shallow Aquifer Systems in a Granitic Terrain: An Integrated Hydro-geophysical Approach.

Groundwater depletion in semi arid granitic terrains demands mapping deep fractures for sustainable irrigation. Our study integrating hydro-geophysical scans, and hydrochemistry successfully detected saturated fractures at 49–67 m depth with high yield (3382 lph) in granitic terrain, southern India.

ERT resolved subsurface lithology, while hydrochemistry confirmed fracture-fed groundwater quality. This approach aids sustainable fracture detection in hard rock and water management policies.
