SWMM
Storm Water Management Model
The United States Environmental Protection Agency (US EPA) Storm Water Management Model (SWMM) is a watershed model that captures processes such as rainfall-runoff dynamics, flow interactions with piped systems and associated water quality implications.

- Model Information
- For more information about this model, go to www.epa.gov
- Spatial Resolution
- The spatial resolution is user defined at the sub-catchment scale.
- Temporal Resolution
- Time series parameters used in the model determine the temporal resolution. Kinematic wave routing model is typically run with 1-5 minute steps. Dynamic routing uses approximately 30 second steps.
- Outputs
- Outputs specifics include flow and water quality characteristics.
- Intended User
- practitioner
- Model Type
- watershed
- Inclusion of Climate Change
- The base version of SWMM has a climate adjustment feature that allows the user to define single or multiple factors by which parameters can be adjusted to account for climate change. The SWMM-CAT add-on incorporates climate change factors directly.
