Abstract: Drought is a recurring phenomenon in many parts of the world, bringing significant water shortages, economic losses and adverse social consequences. Hence knowledge of the drought risk area, their occurrence and their course is an essential aspect for planning. In southern state Ramand district is well known for its frequent monsoon failure, drinking water scarcity and worst drought condition, Remotely sensed data and GIS is widely accepted as a tool for the establishment of integrated information. Drought risk area, by nature, is a result of interrelated parameters concerned. The study area taken in to consideration is Sivagangai taluk , part of old Ramanad district historically a drought prone area. Using geomatic tools detailed analysis has been made with respect to rainfall, water level, subsurface formation, and the geomorphology derived out of remotely sensed data products. The collateral data collected from the field have been converted in to spatial themes and overlay analysis helped to derive the pattern of water level variation, ground water quality deterioration and ground water potential changes. Estimation of ground and surface water potential for a considerable period helped to identify the water stress condition and the same has been correlated with respect to individual villages of Sivagangai taluk. The village wise stress condition helped to plan for effective water resources management by providing recharge and remedial measures to combat the drought condition.
