Abstract

Water is the main source of domestic, engineering, industrial and agricultural uses which affects the surface and groundwater quality and quantity. Geoinformatics encompasses Survey of India (SoI) toposheet, Satellite Remote Sensing (RS), Geographic Information System (GIS) and Global Positioning System (GPS) for mapping & integration of geology, drainage, lineament, soil types, slope category, land use/land cover and other related features in assessing the ground water resources of a region. The present study aims to map, integrate the Geo-informatics application to delineate groundwater potential zones in hard rock terrain of Chitradurga District, Karnataka. Efforts have been made to evaluate the groundwater level contour (in meters) using SoI toposheets (1:50,000) and False Color Composite (FCC) images of IRS-1C/1D PAN+LISS-III (2005-06). Slope map is prepared by using (SoI) topomap (year-2001) of 1:50,000 scale. Thematic maps have been prepared by adopting Visual Image Interpretation Techniques (VIIT) and are integrated using Arc GIS v10 software. The resultant composite coverage is used to classify the area into excellent, good, moderate and poor groundwater potential zones based on certain weightages. This study demonstrates the potentiality of Geo-informatics technique in preparation of more consistent and accurate baseline information on groundwater prospects. The final results highlight the favorable conditions of groundwater potential zones in hard rock terrain in Chitradurga District, Karnataka, which is a suitable model for exploration in similar geological conditions
