| Abstract: | Water is a fluctuating resource making it difficult to measure in time and in space. To demonstrate the efficiency of the
geographic information system (GIS) for groundwater studies, information on the parameters controlling groundwater such as
lithology, geomorphology and lineament analysis were analyzed. LISS-III and Landsat satellite image of the area was used to
infer information on the geologic lineaments and geomorphology. To delineate linear features enhancement and direction, filtering
was performed on single bands of Landsat images. Thematic maps for geology, slope, geomorphology and lineament were prepared
and integrated in GIS by assigning the weights and ranking to various parameters controlling the occurrence of groundwater
to generate the groundwater potential map for the study area. The results indicate that the floodplain of river and its adjoining
areas have very good groundwater potential, whereas the steeply sloping area in the northern part having high relief and slope
possesses poor groundwater potential. |
