Abstract
The rapidly increasing need for water has put tremendous pressure on groundwater resources in areas where it is the prime source of water. The objective of this study is to delineate groundwater potential zone in Kashipur Block, Purulia district, West Bengal, India with dry climate and hard rock terrain. In the present study, groundwater potential zones for the assessment of groundwater availability in Kashipur Block of Purilia District, West Bengal, has been delineated using remote sensing and GIS techniques. Survey of India toposheets and IRS-1C—LISS III satellite imagery. The raster maps of these factors are allocated to a fixed score and weight computed from multi-influencing factor technique. Each weighted layer is statistically computed to get the groundwater potential zones. Weighted Index Overlay modeling technique was used to develop a groundwater potential zone map with three weighted and scored parameters. Although the area is characterized by hard rock, it has groundwater prospective zones due to fracturing, weathering and the presence of valley fills overlying a planation surface. The results reveal that the modeling assessment method proposed in this study is an effective tool for deciphering groundwater potential zones for proper planning and management of groundwater resources in diverse hydrogeological terrains.
