This resource describes several EPA software tools to help your organization plan for, use, and evaluate Green Infrastructure. Learn about EPA’s:

Green Infrastructure Wizard (GiWiz), a database of EPA’s green infrastructure tools and resources.
Watershed Management Optimization tool (WMOST), designed to facilitate integrated water resource management across wet and dry climates,
Visualizing Ecosystems for Land Management Assessment (VELMA) model, to quantify how effective green infrastructure is at reducing pollution from nonpoint sources.
Stormwater Management Model (SWMM), to support your large-scale stormwater management efforts.
National Stormwater Calculator (SWC), to estimate the annual amount of stormwater runoff from a specific location.
