Looking precisely to the above discussion we can conclude that the water is an important natural resource inflow in the being the accumulation of water into the reservoir and an important part of hydrologic cycle should be considered by any irrigation project and its of prime important which should be done accurately .
The various techniques involved in the estimations of inflow suggested that the ANN is the best mostly amongst all the others for calculating inflow .
This concept has already been used for the rain fall –run off process .
