It is also valuable resource for drinking, domestic, livestock use, and irrigation, especially in arid and semiarid regions. The present study investigates the groundwater recharge potential zone as well as to identify potential sites for Groundwater recharge structures using integrated remote sensing (RS), geographical information system (GIS) and multi-criteria decision analysis (MCDA) techniques for augmenting groundwater resources in the Panam basin, middle Gujarat region, India, which has been facing water shortage problems for the past few years. The methodology was implemented at a large catchment scale in Panam Basin with an area of 2348 sq. km. The factors which influence the groundwater recharge are: Lineament density, Stream density, Runoff, Slope, LULC and Soil, have been studied separately as well as utilized to generate thematic layers to identify potential sites of groundwater recharge structures, using GIS and remote sensing techniques. Different themes and their corresponding features were assigned proper weights supported their relative contribution to groundwater recharge within the territory, and normalized weights were figured by applying the Saaty’s analytic hierarchy process (AHP). All the thematic layers have been reclassified and integrated in GIS environment with application of overlay technique to delineate groundwater Recharge Potential zones and identify potential sites.EnglishThesis
