OPTIMAL CONJUNCTIVE USE OF SURFACE AND GROUND WATER

Abstract

Optimal utilization of water resources has grinod great importance due to growing agricultural, industrial and social needs. It is essential that optimal conjunctive use is made of the available surface and ground water resources and benefits from these resources are maximized. In the present study a conjunctive use irriga.. tion planning model has been formulated for the area between Eastern Yamuna canal and. Yamuna river. Linear programming technique has been used to maximize the the net annual irtigation benefit from surface and, . ground water. The objective function of the optiMal conjunctive use planning Model incorporates net benefits from the considered fifteen crops, capital costs and operation and maintenance costs of surface water and ground Water pumping systeMs. It is subjected to a —set of constraints namely, crop area constraints4 crop water requirement constraints, canal water diversion constraints, ground water pumping constraints, ground water mining constraints and constraints for crop management and socio.economic needs.
