Application of River Network Hydrodynamic Model in Determining Water Distribution Scale of Haishu Plain

The water distribution network is an important part of the plain water environment improvement system. To make efficient use of the regional water diversion source, scientifically distribute the water diversion flow and improve the water environment carrying capacity of Haishu Plain, the river network hydrodynamic model is used in this paper to simulate the water intake location, reasonable water quantity and influence range of water transfer in Haishu Plain. The simulation results have high accuracy, which can provide a scientific basis for the scale, water transfer mechanism and project layout of water transfer construction in Haishu Plain and show a strong reference value for the study of water diversion and distribution scheme of coastal plain river network.

海曙区生态活水方案研究

针对城市枯水期水环境问题,研究海曙区生态活水方案,建立研究区MIKE11水量水质耦合模型,统筹考虑不同水源与退水闸碶联合调度,拟定生态活水方案,模拟分析不同方案下水环境改善效果。结果表明,海曙区皎口水库按1.74m^3/s规模下泄,高桥泵站和黄家河泵站分别以13.44、1.00m^3/s规模引水,保丰闸、行春碶和屠家堰配合退水,可取得较好的水环境改善效果。研究成果可为类似区域提供借鉴。
