GROUNDWATER POTENTIAL MODELLING USING REMOTE SENSING AND GIS TECHNIQUES IN PATHRI RAO WATERSHED, HARIDWAR DISTRICT, INDIA

Abstract

Geographical Information System (GIS) and Remote Sensing techniques have been used to develop a methodology for evaluating the groundwater in the Pathri Rao Watershed, Haridwar District, India. Digital satellite data used to prepare thematic maps for the hydrogeomorphology, slope, drainage density and landuse of the area. All thematic maps have been integrated with GIS environments to identifying potential areas for delineate groundwater exploration. The result showed that most promising area for groundwater development is the southern part whereas the high area occupied by Siwalik rocks indicates very poor groundwater potential. The groundwater potential zones map generated through this methodology was verified with the yield data to ascertain the validity of the model developed in the study area by assigning suitable weights to the different attributes affecting on the groundwater potential. The verification showed that the groundwater potential zones demarcated through the model are in agreement with the bore well yield data. Thus, this study has clearly demonstrated the capabilities of remote sensing and GIS technique in delineation of different groundwater potential zones .
