Assessment of Groundwater potential zone using remote sensing and GIS in Varahanadhi watershed, Tamilnadu, India
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 5
Abstract
Groundwater is an important natural resource for its use in domestic, agriculture, and industries purposes. There has been a tremendous increase in the demand for groundwater due to increase in population, advanced irrigation activities and industrial uses. GIS is an effective tool it provides large information with in short period for planning and managing of groundwater related problems. A case study was conducted to find out the groundwater potential zones in Varahanadhi watershed, Tamil Nadu, India. The thematic maps such as geology, geomorphology, soil, land use and drainage map were prepared in the Arc GIS 9.3 for the study area. The thematic layers were first digitized from satellite imagery, supported by supplementary data such as top sheets and field survey data, finally all thematic layers were integrated using Arc GIS software to identify the groundwater potential zones. From the study the groundwater potential zones were classified in to, Poor, Moderate and Good.
