- Abstract:
- At present, the rainwater storage and utilization facilities have the problems such as poor performance to reduce the runoff peak and the lag of scheduling decision. A scheduling decision method was thus proposed according to different actual scheduling requirements. Based on the analysis of regional storm water management model (SWMM), the data of the precipitation nowcasting was used to establish the forecast sequence of the near rainfall, and the differential evolution algorithm was applied to drive the SWMM to search for the optimal decision value to obtain the optimal decision scheme. After using Python to complete the establishment of the corresponding decision system, the advantages and limitations of the scheme in practical application were deeply explored by analyzing the characteristics of the decisionmaking scheme. According to the simulation results, the proposed scheme effectively reduced the peak runoff at the regional outlet and reduced the regional waterlogging pressure.
