This is a 10-minute slide set about the tool "GIWiz" for the Oct 26, 2016 SSWR webinar presentation on the "Green Infrastructure Toolkit". GIWiz is an interactive web application that connects communities to EPA Green Infrastructure tools & resources. GIWi...

While SWMM has arguably played a pivotal role in pollution control in collection systems since its introduction, traditional applications using the model have been relatively static. They typically involve calibrating and validating SWMM models with data collected and curated for...

The purpose of this research was to determine the viability of installing low-cost storm sewer retrofit devices in multiple locations within an urban watershed.  A major component of this was the necessity for designing, fabricating, and operation of such retrofits which are not ...

The U.S. Environmental Protection Agency’s Storm Water Management Model (SWMM) was used to evaluate the potential concentrations and migration pathways of spores spread by urban stormwater following a hypothetical biological agent terrorist attack or accidental pathogen rel...

This is a presentation to students at UC to familiarize them with the basics of EPA's Stormwater Management Model. I will give one presentation over two days. One day we will just do demonstrations of SWMM without any slides and the second day we will take a deep dive into SWMM a...

Management of waste from wide-area radiological incidents will be complicated by several major issues: 1) the potentially enormous quantities of solid and aqueous waste, lightly contaminated with one or more radionuclides, that will need to be properly managed; 2) the profound im...

Enteric disease remains one of the most common concerns for public health. Wastewater treatment plants (WWTPs) receive domestic wastewater from sewer catchments and represent a snapshot of the enteric diseases that are circulating within the serving population, mirroring communit...

This presentation is an overview of ORD's drinking water, stormwater, wastewater and water reuse models that are being used to design, improve, optimize and enhance the resilience of water systems.  This is being presented by Regan Murray, Caleb Buahin, Terra Haxton and Jeff...

To assist in emergency preparedness for a biological agent terrorist attack or accidental pathogen release, potential contaminant levels and migration pathways of spores spread by urban stormwater were evaluated using a Stormwater Management Model (SWMM) of U.S. Coast Guard Base ...

Our nation's water infrastructure is in need of billions of dollars of repairs, upgrades, and replacements. This presentation provides an overview of recent EPA Office of Research and Development research on the topic of resilient water infrastructure, including free models and t...

Presenting a brief introduction to EPA's National Stormwater Calculator at the EWRI Congress

This is a presentation on how homeowners or developers can use EPA's National Stormwater Calculator for LEED v4 documentation for credits and also to help design their green infrastructure low-impact development controls. 

Harvesting precipitation from rooftops is part of many green infrastructure projects to manage storm water and supplement water supplies.  One of the barriers for implementing rooftop rainwater harvesting in the U.S. is limited risk-based treatment guidance for the use of ro...

Stormwater management seeks to reduce runoff and improve water quality, and EPA's Stormwater Management Model (SWMM) has been used for decades to conduct hydrologic, hydraulic, and water quality simulations that aid in planning, analyzing, and designing stormwater drainage system...

This paper compared simulation results from different model constructions of a Storm Water Management Model (SWMM) after radiological contamination from a hypothetical dirty bomb scenario. The model constructions included a utility-provided combined sewer stormwater model, a high...

The EPA Storm Water Management Model (SWMM) is a dynamic rainfall-runoff simulation model used for single event or long-term (continuous) simulation of runoff quantity and quality from primarily urban areas. The runoff component of SWMM operates on a collection of subcatchment ar...

Models, tools, BMPs that combine GI and gray infrastructure, and associated costs/benefits for eliminating urban CSOs.   

EPA’s National Stormwater Calculator (SWC) is a software application tool that estimates the annual amount of rainwater and frequency of runoff from a specific site using green infrastructure as low impact development controls. The SWC is designed for use by anyone interested in ...

The Storm Water Management Model Climate Adjustment Tool (SWMM-CAT) is a simple to use software utility that allows future climate change projections to be incorporated into the Storm Water Management Model (SWMM). SWMM can accept a set of monthly adjustment factors for each inpu...

This presentation will introduce the Storm Water Management Model (SWMM). SWMM is used throughout the world for planning, analysis, and design related to stormwater runoff, combined and sanitary sewers, and other drainage systems in urban areas. There are many applications for dr...

This paper presents the process used to develop an overland flow model of radionuclide transport following an aerosol deposition from a hypothetical radiological dispersal device explosion. The process included the integration of digital elevation, building, and land cover inform...

Understanding the migration path of pollutants is critical to protecting human and environmental welfare, particularly in population-dense settings with a high fraction of impervious materials that contribute to potentially high pollutant wash off. This research measured the rem...

A brief presentation on some of the publically available water modeling software.

The Watershed Management Optimization Support Tool (WMOST) is an EPA application that allows users to find the most cost-effective solutions to meet water quality and quantity goals through integrated water management, considering solutions in stormwater management (green and gra...
