Water Resource Management through Remotesensing and GIS in a Watershed of Gundlupet

ABSTRACT Water is essential commodity for the survival of the human being on the Earth. Fortunately, it is available in suf-ficient amount both from the surface and groundwater sources. But unfortunately its distribution in space and time is highly uneven. Therefore, water resources management practices should be identified using the dynamic form of spatial data set collected through remote sensing and the resulting spatial information and related descriptive attribute must be analyzed through sophisticated computer based data analysis system known as Geographical Information System (GIS). Remote Sensing and GIS have been extensively used in management of water resources by various workers in different geo-environment setup. In view of above, watershed of part of Gundlupet taluk which is a semi arid region has been carried out using remote sensing and GIS techniques. Though Gundlupet receives copious rain but the terrain and soil condition is as such that it allows very little storage of water and hence the region faces shortage of water in dry seasons. Strategy for water management has been studied using the IRS LISS III data, geophysical resistivity and has been analyzed through GIS software, finally water prospects map of the area has been prepared and discussed in this paper
