Research on Water Saving Irrigation and Optimal Allocation of Water Resources

The agricultural irrigation water of Kaifeng is mainly supplied by the Yellow River and the local underground water. According to the conditions of irrigation area water supply and groundwater reduction for many years, the paper puts forward the optimal allocation and the supplying water programs on using combination of surface water and groundwater. By using variable one-dimensional search technology, the nonlinear programming problem will be turned into linear programming problem. Thus, choose different decision variables and different parameters to use computing in order to get to approach the optimal allocation of water resources.
