Detection of water leakage paths using self-potential and geoelectrical resistivity methods: A case study of Kailana Lake-Takht Sagar in the Jodhpur City, Rajasthan, India
Abstract
The present paper characterizes the origin of water leakage from the Kailana Lake-Takht Sagar in the Jodhpur city, Rajasthan, India. Self-potential (SP) method was used to delineate leakage paths; whereas, electrical resistivity method was used to delineate the hydrogeological conditions and identification of fracture zones favourable for water leakage in the study area. Special consideration was focused on the lake, which supports water leakage through cracks, joints, faults and fractures present in the unlined walls or leakage through subsurface structures. The analysis of the integrated results delineates water leakage paths that act as conduits in certain locations through unconsolidated or fractured zones connected from Kailana Lake-Takht Sagar. Additionally, hydrostatic pressure due to increase in the water level of Kailana Lake-Takht Sagar and the presence of many lineaments and its interconnection through Kailana Lake-Takht Sagar, enhance the water leakage problem.
