V.K.Srivastava, Devendra Nath Giri and Pawan Bhardwajal., 2010; Lokesh et al., 2005; Mondal et al., 2007;Rao et al., 2009; Banerji, 2000; Srivastava, 2000 andDasgupta, 1994).The present study area, which is a hard rockterrain, having undulating topography though getsufficient rainfall, suffers from water scarcity fordomestic, agricultural, and industrial purposes due tolimited nature of aquifers (inadequate weathered andfissured zones). Also, sometimes presence of basicand meta-basic dykes and the quartz reefs in the areahave acted as barriers for the flow of water (Singhet al., 1997). Taking into consideration the abovescenario an attempt has been made for mapping ofground water potential zones, by integrating variousthematic maps, as generated from processed andenhanced remote sensing multi band data, digitalelevation model (DEM) created from SRTM dataalong with vertical electrical survey (VES) data andother geo hydrological data in GIS environment.LOCATION, GENERAL GEOLOGY ANDHYDROLOGICAL SET UP OF THE AREAOur study area, Dhanbad district is situated inbetween 23 0 37’30”N - 24 0 56’N lat and 86 0 8’23”E- 86 0 50’18”E long, in Jharkhand state of EasternIndia ( Figure 1). The northern boundary of which ismarked by Barakar river and the southern boundaryby Damodar river, on which two important reservoirsviz Maithon and Panchet are located respectively.The region lies on the eastern part of Chhotanagpurplateau and has an undulating topography with threeFigure 1.
