SWMM模型原理及其在翡翠湖区域的应用

SWMM Model Principle and Its Application in the Emerald Lake Region

经济增长与城市化进程的加快,随之而来的环境污染问题日趋严重。其中以城市暴雨径流污染为代表的城市面源污染成为了危害城市水生态问题的主要问题。本文以安徽省合肥市翡翠湖部分区域为研究对象,采用SWMM软件建立研究区域模型。研究结果表明:该模型的计算结果可靠,能够动态模拟实时和规划条件下各排水片区和街区的地表水力水质变化全过程。研究结论对其他城市类似问题具有较好的参考价值。

With the rapid development of urbanization, urban flooding and runoff pollution are becoming increasingly serious. In this paper, some areas of Emerald Lake in Hefei City, Anhui Province, are thought as the object of study. SWMM software is used to establish a model of the study area. Simulation results show that the model′s calculation results are more ideal, reliable. It can be in real time and planning conditions of the dynamic simulation of the drainage patch and neighborhoods throughout the process of surface hydraulic water quality change. The model is a good reference and guide for similar work in other cities.
