The study was conducted to find out the groundwater potential zones (GWPZ) by using geospatial techniques in Phonda basin in Sindhudurg district of Maharashtra (India). Analytical Hierarchical Process (AHP) was used to demarcate the GWPZ using thematic layers: geology, geomorphology, lineament density, drainage density, elevation, slope, soil, rainfall and land use land cove (LULC). The ranks were assigned for each individual parameter of thematic layer and weights assigned to each thematic layer and final groundwater map was prepared by intersection all thematic layers in Arc GIS environment. GWPZs were categorized as: low, moderate, high and very high. Geological factors are influencing groundwater potentials according to geological formations and human activities. Geological influence approach of delineating the GWPZ is useful for planning and monitoring the groundwater resource for sustainable development.
The groundwater potential zones were detected and delineated using AHP and geospatial techniques.
Thematic layers: geology, geomorphology, lineament density, drainage density, elevation, slope, soil, rainfall and land use land cove (LULC) were used for analyses.
The groundwater potential zones were categorized as low, moderate, high and very high.
Very high groundwater potential is estimated in the area with Deccan basalt having vesicular and vertical joints.
Geological influence approach of delineating the GWPZ is useful for planning and monitoring the groundwater resource.
