Abstract:Groundwater modelling requires data from electrical resistivity surveying and pumping test, which consumes more time and cost for its collection for a larger area. In this study, using remote sensing data and GIS tools, a sequential process is proposed for finding the suitable vulnerable smaller area for groundwater modelling from a relatively larger area. The chosen larger area, Cheyyar river basin, Tamil Nadu, India spreading 4358 km2, has groundwater decline due to aquifer groundwater exploitation. Groundwa… Show more
