摘要
本文介绍了SWMM的相关情况,包括模型的分类、基本理论、数据需求等。阐述了城市暴雨积水预测方法,提出了SWMM与GIS集成的框架,并提出了一种新的自动划分子流域的方法,探讨了利用OSGGIS通过读取SWMM模拟结果,结合地形数据、地物数据等生成三维地形及地物,配合以真实的三维场景从而实现地面水淹过程三维动态仿真的过程。研究结果表明,GIS与SWMM的集成可大大提高计算的效率和计算结果的精度,而实现地面水淹过程的三维动态仿真提供了更为直观和有效的预测手段,可以提高快速反应和应急指挥能力。
In this paper, the model classification, basic theory, data demanding of SWMM are introduced. Next, themethod of simulating and forecasting have been elaborated, the integration frame of GIS and SWMM is proposed, a new methodof sub-watershed partition is suggested, and the method to realize the dynamic visualization of rising and descending waterdepth on the ground is studied, using OSGGIS technology through reading the result of SWMM with DEM data, 3D buildingdata etc. The results show that the application of GIS and RS technology in the process of calculating can extremely improve theefficiency of calculation and the precision of its results. The 3D dynamic simulation realized by integrating GIS technology andSWMM offers a kind of prediction method with more direct-viewing and effective characteristics, which can be applied to establishflood-mitigation measures.
