Description

SWMM is an open-source software application that can be used for single event or long-term simulations of water runoff quality and quantity. The tool evaluates gray infrastructure stormwater control strategies, such as pipes and storm drains, and is useful for comparing the effectiveness and costs of green or gray hybrid stormwater control solutions, especially in urban areas. Furthermore, SWMM allows engineers to determine the effectiveness of green infrastructure practices as low impact development controls in managing runoff. The software provides an integrated environment for editing input data and running simulations.

Tool Outcome

SWMM presents the results of simulation in a variety of formats. These include color-coded drainage area and conveyance system maps, time series graphs and tables, profile plots and statistical frequency analyses.
