The irrigation effici encies if improved, we save the losses of water which in turn will command additional area. Advances in irrigation techno logy provide means to control over water delivery rates to achieve a reasonable balance of upstream losses, deep percolation and downstream tail water losses and greater application uniformity over the fields. The surface irrigation methods viz. furrow, border and basin are generally favoured by the farmers though there are certain added advantages if sprinkler and trickle irrigation systems are used under particular set of conditions. As thevuses for water supplies become more competitive, the need increases for utilising the available water more judiciously and save water whereever possible. The one way of saving the water is to improve the overall efficiency of prevailing irrigation systems. The another way is to use less water per unit of production. One of the ways to improve the efficiency is to estimate the losses and take necessary measures to minimise them. The losses in the irrigation system can broadly be classified as transit losses, management losses and nonbeneficial use of applied water.ennullCALIBRATION OF PARAMETRIC HYDROLOGIC MODEL AND WATER BALANCE STUDIES OF SURFACE IRRIGATION METHODSThesis
