摘要
The exploration for groundwater in hard rock terrains is a complex task. To overcome this complexity, the integrated approach based on advanced applications of remote sensing and geographical information systems (GIS) lends itself as an efficient and effective result-oriented method for studying the development and management of water resources. Chittoor area, comprised of a hard rock terrain, is located in the drought-prone Rayalaseema region of Andhra Pradesh, India. Using remote sensing and GIS technology, groundwater potential zones, along with zones of water quality suitable for domestic purposes, were delineated and classified. Results indicated that, for the town of Chittoor, 1.64% of the area was classified to have very high groundwater potential, with groundwater quality suitable or moderately suitable for domestic purposes; and 31.68% of the area was classified as high potential, with over 31% being suitable or moderately suitable. Most (62.05%) of the area is of moderate groundwater potential, with groundwater quality mostly suitable or moderately suitable for domestic purposes.
