Where EPA SWMM goes next. This organization is the research frontier: transient flow, reinforcement learning, model coupling, and the large model corpora needed to test all three.
1729-SWMM5-Models-2030 is a library of 3,800+ EPA SWMM5 .inp models, each with an auto-generated Markdown summary. It spans hydrology, hydraulics, LID, force mains, pumps, weirs, orifices, and dynamic-wave routing, plus XPSWMM conversions and training examples. When you need to prove an engine change holds across thousands of real networks, this is the test set.
ITM_SWMM couples Arturo Leon's Illinois Transient Model with SWMM, for the mixed free-surface and pressurized flow that the standard Preissmann slot only approximates.
openswmm.engine and HydroCouple carry the C engine and the interface specifications for coupling SWMM to other models.
openswmm.gymnasium wraps the SWMM engine as a reinforcement-learning environment. Train a control policy for real-time gate and pump operation against the model instead of hand-tuning rules.
pybme brings Bayesian Maximum Entropy (Serre and Christakos) to Python, for spatial estimation of rainfall and other fields that feed the model.
swmm5-runoff-explorer rebuilds SWMM5 subcatchment runoff in the browser so you can watch the nonlinear reservoir respond to each parameter.
- dickinsonre is the main personal account.
- SWMMEnablement enhances current SWMM with apps and preserves historical engine code.
- Robert-Dickinson-NS-Apps holds the single-file teaching apps.
- CIMM-ORG is the nonprofit behind the SWMM5plus Fortran engine.
Maintained by Robert (Bob) Dickinson, Autodesk Water Technologist and co-developer of EPA SWMM versions 3, 4, 5, and 5+. Fifty-plus years of continuous SWMM work, from punch cards at the University of Florida in 1974 to reinforcement learning on the engine today. Chair of the SWMM5+ Technical Advisory Committee at CIMM.org and member of the EWRI Stormwater Modeling Committee.
