Several conventional methods such as geological, hydrogeological, geophysical and photogeological techniques are being used to delineate groundwater potential zones (McNeill 1991 Lillesand and Kiefer 1994 Teeuw 1995 Meijerink 1996 Sander et al. Several factors such as geomorphology, land use/land cover, geological structures, fractures, groundwater table distribution, slope and drainage-all contribute in the movement and occurrence of groundwater in an area (Arkoprova et al. The spatially complete and temporal nature of the remote sensing data provides excellent opportunities to hydrogeologists for improving the understanding of the hydrogeological system (Hoffmann and Sander 2007) in any area. Geospatial technology is a rapid and cost-effective tool in producing valuable data on geology, geomorphology, lineaments and slope, etc., that plays a significant role in deciphering groundwater potential zone. Remote sensing and GIS study with its advantages of spatial, spectral and temporal availability of data covering large and inaccessible areas within a short time has come out as an efficient tool to provide the appropriate platform for convergent analysis of large volumes of multi-disciplinary data and decision making for groundwater studies. A groundwater development program requires a large volume of data from various sources. This alarming situation calls for a cost- and time-effective technique for proper evaluation of groundwater resources and management planning. ![]() The significant contribution made for the Green Revolution has further accelerated the rapid decline in groundwater levels. Groundwater is the main source for more than 85% of rural domestic supply and it is rapidly depleting in many areas owing to large-scale withdrawal. The rapid development of this groundwater resource for many purposes has resulted in expansion of irrigation and overall economic development, and thereby improving the lifestyle in India. The outcome of the present study will help local authorities, researchers, decision makers and planners in formulating proper planning and management of groundwater resources in different hydrogeological situations. Finally, the study area has been categorized into four distinct groundwater potential zones-excellent 1.5% (6.45 sq. Weighted index overlay modeling technique was used to develop a groundwater potential zone map with three weighted and scored parameters. The weights assigned to each factor have been computed statistically. To assign weights and ranks to different input factor maps, multi-influencing factor (MIF) technique has been used. Different thematic layers such as hydrogeomorphology, slope and lineament density maps have been transformed to raster data in TNT mips pro2012. The objective of this study is to delineate groundwater potential zone for the assessment of groundwater availability using remote sensing, GIS and MCA techniques. The area is characterized with dry climate and hard rock terrain. The study area belongs to Kashipur block, Purulia district, West Bengal. Assessment, planning and management of groundwater resource are becoming crucial and extremely urgent in recent time. Demand of groundwater resources has increased manifold with population expansion as well as with the advent of modern civilization. ![]()
