عنوان فارسی Mapping Structurally Favourable Zones of Water Seepage Using Remote Sensing and Geophysical Methods in Western Rajasthan, India
چکیده فارسی مقاله The presence of cracks, joints, faults, fractures and lineaments and their interconnectivity influence the water movement in hard rock areas. The groundwater level in Jodhpur city, western Rajasthan, has been rising significantly over the past few years, and this has attracted attention due to the region’s unfavourable impacts. In many parts of the city, particularly around popular markets, water levels have touched the ground. The rise in groundwater levels has caused water seepage in the basements of underground shops and houses throughout the city. Traditional field survey techniques require a lot of money and effort to map water seepage zones. In this study, subsurface signatures of linear features, faults and fractures were quickly and inexpensively mapped using a remote sensing methodology. Fracture zones that are prone to water seepage were identified using an electrical resistivity method. Based on meticulous analysis of satellite imagery, a number of minor and large lineament sets have been mapped, the majority of which cross over Kailana Lake-Takht Sagar and enter the city. According to the study of all available data, fractured zones exist, are linked by Kailana Lake-Takht Sagar, and act as conduits for water seepage. The presence of obvious lineaments also facilitates water seepage.
