A Geospatial Evaluation of SRTM DEM for Representative Groundwater Sampling of Rajnagar Block, Odisha, India

Present research deals with the representative groundwater sampling locations establishment for the geochemical evaluation of the subsurface aquifer systems of Rajnagar Block, Odisha along the east coast of India. The study looks into the hydrological, topographical and geological set up of the area to evaluate the natural influencing factors and the cultural set up of the human habitats and its interrelationship with the subsurface water elemental variation towards that of the anthropogenic ones. The research proposes fifty three discrete ground control points which can replicate the subterranean water chemistry of the concerned water bearing formations from the analysis of existing geological records of Geological Survey of India, hydrologic as well as topographic interpretation of Shuttle Radar Topographic Mission DEM coupled with the reconnaissance survey of the area.
