Groundwater resources of coastal regions in developing countries are mostly affected due to the combination of natural disasters as well as poor storm water management. By identifying the suitable places for the construction of Managed Aquifer Recharge (MAR) structures will improve the groundwater potential in an area and also sustain the groundwater resources. The present study was carried out in northern coastal part of Tamil Nadu, India. The objectives of this study are to delineate the groundwater potential zones (GWPZ) and to identify the optimal locations for the construction of MAR structures. Geomorphology, geology, slope, lineament density, drainage density, rainfall, regional groundwater level and land use of the study area were selected as the key factors for this study. The selected factors are processed with combination of Analytic Hierarchy Process (AHP), Multi-Criteria Decision Making (MCDM) technique and Boolean logical approach to delineate GWPZ and to identify the optimum locations for the construction of MAR structures. The processed results specifies that 2.0% (51 km2) from total study area falls under Excellent; 32% (938 km2) are good; 4.0% (115 km2) are above average; 59% (1759 km2) are fair and 3% (92 km2) has poor groundwater potential. Eventually, the Boolean logical method was attempted and identified the suitable areas for constructing MAR structures such as check dams, percolation ponds, flood and furrows and ditch and furrows. Based on the regional hydrological setup, feasible locations for construction of check dams were proposed, which will augment the groundwater resources of the study area. These check dams will be beneficial for the surrounding regions by improving the groundwater recharge through cropping the surface runoff during the monsoon as well as flood periods.
