| Abstract | ||
| Anomalous seepage and groundwater accumulation in the basements of shops and houses in Jodhpur City, Rajasthan, are weakening foundations and reducing the lifespan of buildings due to damp walls and erosion. Therefore, identifying favourable fractured zones for groundwater seepage becomes crucial in this area. To investigate groundwater seepage flow paths, integrated geophysical surveys were conducted using self-potential (SP), geo-electrical resistivity, and very-low-frequency (VLF-EM) electromagnetic methods. Seventy-one vertical electrical soundings (VES) were carried out, along with three SP and three VLF profile lines using the Schlumberger array arrangement. The SP anomalies indicate groundwater flow through fractured formations. Geoelectrical and VLF cross-sections revealed the presence of fractured and semi-fractured rhyolite at depths ranging from 10 to 45 metres. The integrated results demonstrate that groundwater seepage flow paths are influenced by joints, cracks, and fractured zones, serving as conduits for groundwater flow in the study area. | ||
