Remote sensing and geographical information system (GIS) has become one of the leading tools in the field of groundwater research, which helps in assessing, monitoring, and conserving groundwater resources. This paper mainly deals with the integrated approach of remote sensing and GIS to delineate groundwater potential zones in hard rock terrain. Digitized vector maps pertaining to chosen parameters, viz. geomorphology, geology, land use/land cover, lineament, relief, and drainage, were converted to raster data using 23 m×23 m grid cell size. Moreover, curvature of the study area was also considered while manipulating the spatial data. The raster maps of these parameters were assigned to their respective theme weight and class weights. The individual theme weight was multiplied by its respective class weight and then all the raster thematic layers were aggregated in a linear combination equation in Arc Map GIS Raster Calculator module. Moreover, the weighted layers were statistically modeled to get the areal extent of groundwater prospects with respect to each thematic layer. The final result depicts the favorable prospective zones in the study area and can be helpful in better planning and management of groundwater resources especially in hard rock terrains.

“…A number of workers such as Edet and Okereke (1997), Murthy (2000), Obi Reddy et al (2000), Pratap et al (2000), Singh and Prakash (2002) and Jaiswal et al (2003), Chowdhury et al (2009), Magesh et al (2012 and Nag and Ghosh (2012) and others have used GIS techniques to delineate ground water potential zone. In recent years, extensive use of satellite data along with conventional maps and rectified ground truth data has made it easier to establish the base line information for ground water potential zones (Tiwari and Rai 1996;Das et al 1997;Thomas et al 1999;Harinarayana et al 2000;Muralidhar et al 2000;Chowdhury et al 2010).…”

“…Similar attempts have been made in the generation of different thematic maps for the delineation of groundwater potential zones in different parts of the country (Obi Reddy et al, 1994;Krishna Moorthy and Srinivas, 1995;Rao et al, 1996;Reddy et al, 1996). Satellite remote sensing has been proved beneficial in hydrogeomorphological mapping (Vaidyanathan, 1964;Prithviraj, 1980;Das et al, 1997; Kumar and Tomar, 1998;Tomas et al, 1999;Pratap et al, 2000;Subba Rao et al, 2001, Sankar, 2002Jagannadha Rao et al, 2003).…”

The role of hydrogeomorphological units and lineaments in tile storage of groundwater from the Muvattupuzha river basin has been investigated using IRS ID LISS Ill data. Other than the usual water bodies such as river course, reservoirs and ponds, the major hydrogeomorphologica[ units identified in this basin in the descending order of their groundwater potential are: valley fills, moderately dissected plateau, pediments, residual mounts, residual mount complex, linear ridges, residual hills and structural hills. Majority of the lineaments trends in NW-SE and WNW-ESE directions. Even though the eastern part of the basin is characterised by moderate to high lineament density, the above area is found to be poor to moderate groundwater prospect zone because of high gradient and structural hills. Tile pump test analyses of dug wells from different hydrogeomorphic units also confirm that valley fills are the most promising unit lot groundwater prospecting than the rest.
