摘要
SWMM模型可模拟现实世界径流汇集而成的水文状况,软件将径流水文划分为不同状况的子汇集区,不同子汇集区有不同的物理特性,分别模拟推演各子汇集区,最后把模拟结果汇总到排水渠端口。文章介绍了SWMM模型原理,运用SWMM计算模型,以某地区为例进行模拟与评估分析,旨在模拟预测未来不同时段、不同降雨情况下城市内涝和排水情况,进而降低发生洪涝的可能性。
The SWMM model can simulate the hydrological conditions formed by the convergence of runoff in the real world.The software divides the runoff hydrology into sub-convergence areas with different conditions.Different sub-convergence areas have different physical characteristics.Each sub-convergence area is simulated and deduced respectively,and the simulation results are finally summarized at the drainage channel port.This paper introduces the principle of SWMM model,and uses SWMM calculation model to conduct simulation and evaluation of an area as an example,aiming to simulate and predict urban waterlogging and drainage conditions in different time periods and different rainfall conditions in the future,so as to reduce the possibility of flooding.
