Toolkit of Available EPA Green Infrastructure Modeling Software: Watershed Management Optimization Support Tool (WMOST)
Detenbeck, N. Toolkit of Available EPA Green Infrastructure Modeling Software: Watershed Management Optimization Support Tool (WMOST). Safe and Sustainable Water Reources (SSWR) Webinar Series, NA, October 26, 2016.
Stormwater discharges continue to cause impairment of our Nation’s waterbodies. Conventional stormwater infrastructure, or gray infrastructure, is largely designed to move stormwater away from urban areas through pipes and conduit. Runoff from these surfaces can overwhelm sewer systems and end up contaminating local waterways. When stormwater runs off impervious streets, parking lots, sidewalks, and rooftops, it carries pollutants such as motor oil, lawn chemicals, sediments, and pet waste to streams, rivers, and lakes. Runoff flows can also cause erosion and flooding that can damage property, infrastructure, and wildlife habitat. In addition to runoff problems, impervious surfaces also prevent water from penetrating the soil and recharging groundwater supplies. Green infrastructure (e.g., rain gardens, green roofs, porous pavement, cisterns) is becoming an increasingly attractive way to recharge aquifers and reduce the amount of stormwater runoff that flows, untreated, into wastewater treatment plants or waterbodies. It provides many environmental, social, and economic benefits that promote urban livability, such as improved surface water quality, water conservation, and aesthetic and property value. Green infrastructure is also incorporated into municipal separate storm sewer system (MS4) and National Pollutant Discharge Elimination System (NPDES) stormwater permits for retention requirements for various states across the Nation. EPA researchers have been studying green infrastructure practices and developing models and tools to help communities manage their stormwater runoff and address nutrient impairment. This webinar will present a toolkit consisting of five EPA green infrastructure models and tools, along with communication material, that can be used as a teaching tool and quick reference resource for use by planners and developers when making green infrastructure implementation decisions and can also be used for low impact development design competitions. Models and tools included: Green Infrastructure Wizard (GIWiz), Watershed Management Optimization Support Tool (WMOST), Visualizing Ecosystem Land Management Assessments (VELMA) Model, Storm Water Management Model (SWMM), and the National Stormwater Calculator (SWC).
Watershed Management Optimization Support Tool (WMOST) is a software application designed tofacilitate integrated water resources management across wet and dry climate regions. It allows waterresources managers and planners to screen a wide range of practices across their watershed or jurisdictionfor cost-effectiveness and environmental and economic sustainability. WMOST allows users to select up to 15stormwater management practices, including traditional grey infrastructure, green infrastructure, and otherlow impact development practices.
