SWMM

 

SWMM是国内外普遍使用的暴雨洪水管理模型，可以用于作为雨洪相关的规划、分析和设计，兼做污水管网和合流排水系统分析工具。软件可以用来评估灰色基础措施的雨水控制策略，例如雨水管渠的排水能力，同时SWMM也是一款非常优秀的绿色-灰色基础设施成本效益解决方案工具。SWMM帮助政府部门管理城市雨洪，通过渗透和滞留减少雨水径流，同时减少径流污染的排放，避免对水体造成损害。

 

2022年02月01日，美国环境保护署发布了Storm Water Management Model (SWMM)的最新版本 SWMM 5.2.0。本次更新发布了32位和64位两个版本的程序，同时对软件源代码和Bug进行了更新和修复。官方网站还同时发布了SWMM 5.2.0 用户手册。

 

相对于之前的SWMM 5.1.X 版本的响应式界面优化和添加几项功能，美国环境保护署这次对SWMM进行了非常大的调整，虽然SWMM 5.2.0在整体上还是延续了SWMM 5.1.X的界面风格，但如果详细体验后，会发现大部分的更新和优化还是掩藏在用户界面内部和各个功能上，个人感觉SWMM 5.2.0可能会成为一款跨越式的产品，就像iPhone 4 之于苹果，AutoCAD2008之于Autodesk。
