swmm6

A library of 3,800+ EPA SWMM5 (.inp) models — hydrology, hydraulics, LID, force mains, pumps, weirs, orifices, and dynamic-wave routing, plus XPSWMM conversions and training examples — each with an auto-generated Markdown summary.

An open-source Web UI for OpenSWMM 6. Analyze .inp models combined with GeoJSON layers, customize visualization colors, overlay Google Street View, and run simulations on your browser.

Browsable catalog of proposed new features and enhancements for the EPA SWMM5 engine.

Interactive single-file browser tool for exploring SWMM5 subcatchment runoff — width, slope, imperviousness, and infiltration effects on the hydrograph.

Full-stack web app for uploading, discretizing, and batch-running SWMM models through the browser instead of file-by-file: multi-scenario runs, discretization change summaries, and AI-powered report generation, with bundled EPA SWMM5 and SWMM6 engines.
