OPTIMAL RESERVOIR AND BACK RUNOFF CHANNELS BASED TWO FARMS IRRIGATION TOTAL DISCHARGE PREDICATION SYSTEM

Global water withdrawal for agricultural sector is approximately 70%. However most of this fresh water approximately 50 % is wasted due to inefficient and poorly managed irrigation system. The farming community in under develop countries of the world is wasting a huge amount of fresh water by using outdated and poorly managed flood irrigation (surface irrigation).Runoff estimation/prediction can be very valuable in water management and irrigation scheduling management. In this research article an optimal reservoir precision irrigation system based on runoff estimation between two farms (farm1 and farm2) has been proposed to reduce water waste and to utilize the runoff water in nearby farm i.e farm2 or divert it back to reservoir through back runoff channels from both the farms in case of surplus amount of water left from either irrigation or there is an excessive rainfall.
