【摘要】 为解决我国城市化进程中的水安全和水环境问题,结合海绵城市建设理念和河道综合整治目标,分析暴雨洪水管理模型(storm water management model, SWMM)和MIKE 11模型的适用范围、具备优势和存在不足。结果表明,SWMM广泛应用于径流总量控制和面源污染削减的模拟,但是无法模拟河道中污染物的对流扩散和生化过程;MIKE 11河网模型广泛应用于城市河道水量和水质模拟,可预测特定条件下的河道水环境变化情况,但是无法反映陆域面源污染对河道水质的冲击影响。构建SWMM-MIKE 11耦合模型,利用SWMM进行海绵设施和雨水管网模拟,将SWMM中管网排口径流作为边界条件导入到MIKE 11模型中,可以实现二者优势互补。更多还原

【Abstract】 In order to solve the problems of water safety and water environment in the process of urbanization in China, combined with the construction concept of sponge city and the goal of comprehensive river regulation, the application scope, advantages and disadvantages of SWMM model and MIKE11 model were analyzed. The results show that SWMM model is widely used in the simulation of total runoff control and non-point source pollution reduction, but it cannot simulate the convection diffusion and biochemical process of pollutants in river channels. MIKE 11 river network model is widely used in the simulation of urban river water quantity and quality. It can predict the changes of river water environment under specific conditions, but it cannot reflect the impact of land-based non-point source pollution on river water quality. SWMM-MIKE 11 coupling model can be built by using the SWMM to model the sponge facilities and rainwater pipe network, and importing the pipe network discharge flow of SWMM as the boundary condition into MIKE 11 model, so as to realize the complementary advantages of the two.更多还原
