Geohydrological Studies in and Around Talupula- Nambulapulakunta, Anantapur District, Andhra Pradesh,Using Remote Sensing Techniques

摘要

Remote sensing techniques using satellite imagery have proved to be an indispensable tool in morphmetric analysis and ground water studies. Remote sensing techniques with an emphasis on lithological and structural identification plays a great role in ground water prospecting and applied on hard rock area of Talupula and Nambupulakuntapalli of Anantapur district. Geohydrological studies have been carried by using satellite data for the study area through visual interpretation of IRS P6 LISS111 imagery 57J/08 of on a scale 1:50000. The area has been visually interpreted to delineate various geology, geo-morphology and geohydrologic units for the development of ground water potential zones. The geohydrological map delineated depicts 4 zones in which high potential zones carries a better ground water resource,when compare to the medium and low potential zones. Where as non potential zones are of barrier lands with hard rock terrain.
