In this study from the GIS Development site,  the hydrogeophysical parameters generated from vertical sounding, geohydrological, inferred fractures and geomorphic zones derived from remotely sensed data have been analysed in Kewta watershed of upper Barakar Basin, Hazaribagh. The study area is part of lower Hazaribagh plateau and is part of pediplain developed over Chotanagpur granite gneiss and meta- sedimentary.

The study area falls between latitude 240 09' - 240 13' and longitude 850 20' - 850 28'. Topography varies from 600 - 450 m.s.l. In study area electrical resistivity survey ( VES ), remote sensing and routine geohydrological studies have been carried out. DBTM has also been prepared to understand the aquifer storage and retrieval system. An attempt has been also made to estimate the groundwater reserves of entire aquifer system Various spatial and non-spatial data base related to groundwater has been analysed in GRAM++ window based Geographic Information System ( GIS ) for planning and management of groundwater.

The results indicate that there are numerous sub-surface basins/ underground reservoirs, which can be used for groundwater storage and retrieval. Reserve estimation indicates that entire aquifer has storage capacity to irrigate 50 per cent geographical area of watershed. However, the present replenished groundwater reserve has potential to irrigate only 30 per cent of the geographical area of the study area and it has not been fully utilised. With the help of DBTM, old river channel has been also traced out.
