Popis: In order to identify the water scarcity or drought situations and its severity, it is very important to understand the water balance process over earth. It is the cyclic process in which the water balance is maintain through continuous processes of evaporation, condensation and precipitation. The atmospheres acquires moisture by evaporation from oceans, lakes, rivers and damp soil or from moisture transpired from plants taken together, this area often referred to as evapotranspiration (Darry and Chorley ,1969,pp-58). And after the process of condensation water vapours are again con- verted in to solid or liquid state and precipitate on the ground. In this way the hydrological cycle is completed. So, the water surplus areas and deficit areas are identified with the help of total evapotranspiration from the earth to the atmosphere and precipitation over the earth. For the present investigation the water balance of Indian states are mainly determined by potential evapotranspiration from earth to atmosphere and reverse of water to the ground surface is determined by precip- itation over the ground surface. With these above mentioned two climatic elements Thornwaite's TMI values are calculated and water deficit and surplus areas are marked.
