Testing of SWMM Model’s LID Modules (PRESENTATION)
EPA’s Storm Water Management Model (SWMM) is a computational code heavily relied upon by industry for the simulation of wastewater and stormwater infrastructure performance to . design and build multi-billion-dollar, multi-decade infrastructure upgrades. Since the 1970’s, EPA a...
SWMM Modeling Methods for Simulating Green Infrastructure at a Suburban Headwatershed: User’s Guide (PUBLISHED REPORT)
Urban stormwater runoff quantity and quality are strongly dependent upon catchment properties. Models are used to simulate the runoff characteristics, but the output from a stormwater management model is dependent on how the catchment area is subdivided and represented as spatial...
SWMM LID Module Validation Study (PRESENTATION)
EPA’s Storm Water Management Model (SWMM) is a computational code heavily relied upon by industry for the simulation of wastewater and stormwater infrastructure performance. Many municipalities are relying on SWMM results to design multi-billion-dollar, multi-decade infrastructu...
SWMM5 Application Programming Interface and PySWMM: A Python Interfacing Wrapper (PRESENTATION)
In support of the OpenWaterAnalytics open source initiative, the PySWMM project encompasses the development of a Python interfacing wrapper to SWMM5 with parallel ongoing development of the USEPA Stormwater Management Model (SWMM5) application programming interface (API). ...
Stormwater Management Model (PRESENTATION)
SWMM is a model for urban hydrology. It has a long history and is relied upon by professional engineers in the US and around the world. SWMM provides both gray and green Infrastructure modeling capabilities. As such, it is a convenient tool for understanding the tradeoff between ...
Toolkit of Available EPA Green Infrastructure Modeling Software. National Stormwater Calculator (PRESENTATION)
This webinar will present a toolkit consisting of five EPA green infrastructure models and tools, along with communication material. This toolkit can be used as a teaching and quick reference resource for use by planners and developers when making green infrastructure implementat...
Storm Water Management Model (SWMM) (COMMUNICATION PRODUCT)
Stormwater discharges continue to cause impairment of our Nation’s waterbodies. Regulations that require the retention and/or treatment of frequent, small storms that dominate runoff volumes and pollutant loads are becoming more common. The U.S. Environmental Protection Agency (E...
