- Abstract:
- Caidian East Lake water system is a complex system composed of storing lakes, drainage channels, pumping stations and gates. At present, there is lack of combined dispatching in the water system, and the contradiction between regional drainage dispatching and water environmental protection is prominent. Therefore, a reasonable dispatching scheme was proposed to make full use of the lake regulation and storage capacity according to the actual demand of regional drainage, and the dispatching performances before and after typical rainfall were compared and analyzed by using the hydraulic model. The recommended optimized dispatching scheme effectively reduced the drainage pressure and risk in the areas requiring priority protection, gave full play to the regulation and storage capacity of Houguan Lake, and increased the maximum water level of Houguan Lake by 0.52 m and the duration by 769.3 h. In addition, the influence of water pollution caused by drainage was also reduced as far as possible.
