Abstract
Sustainable water resource development and management necessarily depends on proper planning, implementation, operation and continuous monitoring. In India, potable water supply to all people in both rural and urban is a major unsolvable problem to the government because of increasing population and decreasing water resources. The Remote sensing and GIS technology has a vital role to play in water resource studies, and it has to be effectively used to replace, complement and supplement the earth resources with time and cost effective methodologies. In this study, digital image processing based interpretation and classification of Landsat ETM+ Imagery was used to identify and extract landform features, and SOI toposheet number 58 F/4 and 58F/8 with 1:50000 scale was used to delineate watershed. All the spatial and non spatial, statistical data were entered in GIS software to analyse and produce a model. The model used to select appropriate site for construction of farm ponds, loose rock check dams, water absorption trench and recharge beds in and around the study area for rain water harvesting and improving the level of ground water permanently.
