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.

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.

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.
