Artificial recharge of aquifers has emerged as a viable solution to counter the increasing depletion and degradation of groundwater in various river basins worldwide. The present study focuses on identifying suitable sites for potential recharge structures in the Kadalundi River Basin (KRB), located in Southern India, which experiences water scarcity during summer season. The study investigates the basin's potential for artificial recharge by analyzing various geo-environmental variables using Remote Sensing (RS), Geographical Information System (GIS), and the Analytic Hierarchy Process (AHP) technique. The considered geo-environmental variables include drainage density, rainfall, soil texture, lineament density, land use/land cover, available space for recharge, slope, geomorphology, and geology. Furthermore, the study identifies suitable locations for four site-specific groundwater recharge mechanisms: rainwater infiltration pits, percolation ponds, injection wells, and pond-cum-injection wells, using a rule-based approach. The groundwater recharge potential map reveals that 10% of the basin falls under a very low recharge potential class, while 28% falls under a low recharge potential class. Moderately suitable recharge potential covers 36% of the basin while 20% and 6% of the basin are classified as high and very high recharge potential zones, respectively. The western and central-eastern parts of the study area mainly consist of high and very high recharge potential zones. Rainwater pits are suitable in most areas except the east and some random locations. Percolation ponds are suitable in the central-eastern and central-western regions. The locations for injection wells and pond-cum-injection wells are distributed randomly across the study area.
