Description

technical field [0001] The invention belongs to the technical field of joint scheduling optimization of surface water and groundwater, and in particular relates to a joint scheduling optimization method of surface water and groundwater based on an improved pollen algorithm. Background technique [0002] At present, the water resources in the arid areas of our country are relatively short, which has seriously affected the sustainable development of the arid areas. At this stage, the joint dispatching of surface water and groundwater has become an important measure to solve the shortage of water resources in arid areas. As an important part of the joint regulation of groundwater and surface water, the operation mode of the reservoir has received special attention; however, the optimal regulation of the reservoir is nonlinear, high-dimensional and complex. At present, the optimal dispatching methods of reservoirs are mainly divided into traditional methods and optimization met...
