Storm Water Management Model (SWMM)

The EPA Storm Water Management Model (SWMM) is a dynamic rainfall-runoff simulation model used for single event or long-term (continuous) simulation of runoff quantity and quality from primarily urban areas. The runoff component of SWMM operates on a collection of subcatchment areas on which rain falls and runoff is generated. The routing portion of SWMM transports this runoff through a conveyance system of pipes, channels, storage/treatment devices, pumps, and regulators. SWMM tracks the quantity and quality of runoff generated within each subcatchment, and the flow rate, flow depth, and quality of water in each pipe and channel during a simulation period comprised of multiple time steps. SWMM was first developed back in 1971 and has undergone several major upgrades since then. The current edition, Version 5, is a complete re-write of the previous release. Running under Windows, EPA SWMM 5 provides an integrated environment for editing drainage area input data, running hydraulic and water quality simulations, and viewing the results in a variety of formats. These include color-coded drainage area maps, time series graphs and tables, profile plots, and statistical frequency analyses.

美国环境保护署（EPA）的雨水管理模型（SWMM）是一款动态降雨径流模拟模型，主要用于模拟单个事件或长期（连续）的城市地区径流量及其质量。SWMM的径流部分在多个子流域区域上运行，这些区域降雨并产生径流。模型的输送部分则通过管道、渠道、储存/处理装置、泵和调节器等输送系统传输这些径流。SWMM能够追踪每个子流域内产生的径流量及其质量，以及模拟期间每个管道和渠道的水流速度、水流深度和质量。SWMM最初于1971年开发，自那时以来已经历了多次重大升级。当前的第五版是一个对先前版本的全盘重写。运行于Windows系统下的EPA SWMM 5提供了一个集成环境，用于编辑排水区域输入数据、执行水力学和水质模拟，并以多种格式查看结果。这些包括彩色编码的排水区域地图、时间序列图和表格、剖面图以及统计频率分析。
