Water is the prime resource responsible for sustaining life in the earth. Water within a river basin has to be properly allocated for various uses like generation of electricity, domestic supply, for irrigation, for industrial use, and in some cases for recreation as well. On par with this is the disposal of domestic waste, effluents and other pollutants forming the other side of the water distribution. To add to these are the vagaries of monsoon affecting the basin by extreme drought or flood. Rivers of Tamil Nadu can be grouped into 17 river basins (127 sub-basins) a majority of which are water-stressed. The average annual rainfall is 950 mm with bimodal distribution. Water Balance equation is the general term used to describe the flow of water in and out of a river system. It is illustrated using a water balance graph which plots the precipitation, evapotranspiration on a month wiseinterval. Classification of river basins into surplus basins and deficit basins is the prime requirement for allocation of water in various sectors and exchange of water from surplus basins to the deficit basins. This paper highlights the ways and means to restore, revive and replenish the available water resource in a judicial manner. To some extent the location and nature of surface water bodies (rivers, lakes, tanks, and reservoirs) are controlled by the geology and geomorphology (land forms) of the area and some data is provided on this aspect as well of the study area.
