Water Resources Optimization In Yellow River Diverting Irrigation Area

The local water resources in Yellow River diverting irrigation area is in short supply, to solve the problem, more than 7 billion Yellow River water were diverted. Recent years, the discharge of Yellow River is decrease, so the water volume diverted from Yellow River will also be in short supply.Aimed at the irrationality use of the water resources, such as attaching importance to yellow River, insufficient use of ground water, the paper gives the maximum net benefits and corresponding water volume both Yellow River water and ground water, through the use of linear programming. The paper also analysis the change of benefits and distribute of the water resources when we have different prices on Yellow River water.In consideration of the short of Yellow River, the paper presents the optimization decision variable, i.e., the yellow River water volumes used for irrigation, by applying the tolerance approach of fuzzy linear programming.In the end, the paper gives more suggestions on combined use of yellow River water and ground water, rational distribution of irrigation wells, and allocation of yellow River diverted into the irrigation area.
