Mapping of Groundwater Prospective Zone in Urbanizing Coastal Regions for Sustainable Development

The exploitation of coastal aquifers to meet groundwater demand for drinking, farming, and industry is lowering groundwater levels and aquifer potential. Therefore, mapping the groundwater potential areas is important along the coastline to examine the groundwater scenario. The Groundwater Potential Zone (GWPZ) map was developed using Remote sensing, Geographic information system (GIS), and Multi-Influencing Factor (MIF) techniques along Odisha’s coast. The geomorphology, geology, rainfall, landcover/land use, slope, drainage density, and soil thematic maps were used for determining GWPZ. Approximately 78% of the study region is a “good” GWPZ. The output was cross-validated with Central Groundwater Board (CGWB) water level data. Prospects rated MIF’S GWPZ map with 88% reliability. This research will aid in the preparation of a sustainable groundwater planning map and policy.
