Abstract
A procedure is presented for ground water exploration in terms of depth and quality in an alluvial terrain with shallow groundwater occurrence. The study area forms a part of the marginal Gangetic terrain with a clay-sand sequence. Variation in groundwater quality has been mapped in earlier research on the basis of field sampling and chemical analysis of groundwater. In the present study, a scheme of image processing and GIS techniques using false colour composites, vegetation indices, density slicing, image registration, overlaying, and supervised classification has been applied on IRS-1B LISS II data. Various zones established within the terrain based on our research are in conformity with ground water salinity and depth contours.
