Application of the Sea-Level Affecting Marshes Model (SLAMM) to the Lower Delaware Bay, with a Focus on Salt Marsh Habitat ()
Coastal salt marshes--which provide valued ecosystem services such as flood control, water purification and critical habitat--are vulnerable to ongoing sea level rise, which is interacting with physical and biological attributes of the system to induce complex changes in salt mar...
Future of Water Distribution Modeling and Data Analytics Tools (PUBLISHED REPORT)
The U.S. Environmental Protection Agency (EPA) is responsible for helping communities prepare for and recover from disasters that result in threats to public health and the environment. EPA’s National Homeland Security Research Center’s (NHSRC) mission is to focus on the research...
Modeling Water Age in Premise Plumbing Systems (PRESENTATION)
Water quality in homes and buildings is impacted by a combination of the incoming water chemistry, characteristics of the unique plumbing system, and how the water is used. Modeling premise plumbing systems enables the examination of different aspects of hydraulics and water qual...
Monitoring and Operating Internal Building Drinking Water Distribution Systems to Maintain Drinking Water Quality (PRESENTATION)
Establish adequate sampling points for hot and cold water collection (faucets and shower heads) that represent spatial variability in water. Develop sampling protocol to monitor water quality from the targeted sampling points. Identify critical water quality parameters to be moni...
Numerical Modeling of Premise Plumbing Systems Considering Dispersion Effect (PRESENTATION)
The presence of contaminants in drinking water premise plumbing systems (PPS) remains a significant public health issue. Water quality in plumbing can be affected by various factors such as pipe materials, pipe scales, water chemistry, and water usage patterns. Intermittent water...
Using Hydraulic Modeling Tools to Assess the Resilience of Drinking Water Distributions Systems (PRESENTATION)
Water distribution systems are among the most critical civil infrastructure and must be prepared to withstand or quickly recover from any disruptive incident. With increasing threats to drinking water systems, including natural disasters, water shortages, power outages, bioterro...

AN OVERVIEW OF THE WATER NETWORK TOOL FOR RESILIENCE (WNTR) - Canada (PAPER IN NON-EPA PROCEEDINGS)
WNTR integrates hydraulic and water quality simulation, a wide range of damage and response options, and resilience metrics into a single software framework, allowing for end-to-end evaluation of water network resilience. WNTR includes capabilities to 1) generate and modify water...
An Overview of the Water Network Tool for Resilience (WNTR) (PRESENTATION)
The Water Network Tool for Resilience (WNTR) is a new software package that integrates hydraulic and water quality simulation, a wide range of damage and response models, and resilience metrics into a single software framework, allowing for end-to-end evaluation of drinking water...
Aquatic Sentinels Forecasting Human Exposure To Emerging Contaminants (PRESENTATION)
Most of us have heard the axiom, “canary in the coal mine”. These melodious exposure indicators - a necessity in U.K. mines well into the 20th century - were especially sensitive to methane and carbon monoxide gases, and would cease singing (and oftentimes die) at le...
Let's Get Moving and Write Software: an Open Source Project for EPANET (JOURNAL)
Water infrastructure simulation models, such as EPANET and SWMM, have played a significant role in simulating water distribution, stormwater and sanitary sewer systems. These software packages have played an important, and varying, role to different portions of the water infrast...
Mass Imbalances in EPANET Water-quality Simulations (JOURNAL)
This journal article examines EPANET, which is widely employed to simulate water quality in water distribution systems. However, the time-driven simulation approach used to determine concentrations of water-quality constituents provides accurate results, in general, only for smal...
Modeling Drinking Water Lead Exposure from Premise Plumbing (PRESENTATION)
Exposure to drinking water contaminants, specifically lead, remains an important health concern. Modeling lead release within home plumbing systems includes quantifying the dissolution of lead into the water from all lead sources, and the transport of that lead through the pipes/...
Modeling of Dispersion Effect for Intermittent Flow in Home Plumbing Systems (PRESENTATION)
Modeling tools for water distribution systems have been developed and used for many years, however, only limited attention has been given to home or premise plumbing modeling. Recent issues in Flint, MI highlighted the need for modeling premise plumbing systems (PPSs) and their u...
Modeling of Dispersion Effect for Intermittent Flow in Premise Plumbing Systems (PAPER IN NON-EPA PROCEEDINGS)
Modeling tools for water distribution systems have been developed and used for many years, however, only limited attention has been given to home or premise plumbing modeling. Recent issues in Flint, MI highlighted the need for understanding premise plumbing systems (PPSs) and ...
Open Source EPANET: Community-Based Software Development for Drinking Water Infrastructure Modeling (SUMMARY)
Research summary for EPANET. EPANET was created by the US EPA in the 1990s out of a need to better understand water quality transport processes in water distribution systems. Work ceased in 2000 and it last received a minor update in 2008. In the intervening time, EPANET has bec...
Open Source EPANET: Community-Based Software Development for Drinking Water Infrastructure Modeling - Minneapolis (PRESENTATION)
To better support EPANET stakeholders and the needs of the water community, EPA has initiated an open source software (OSS) project to advance and maintain EPANET.
Resilience Analysis Using the Water Network Tool for Resilience (PRESENTATION)
Recent hurricanes and earthquakes have highlighted the essential role of drinking water infrastructure in our everyday life as well as the vulnerability of this critical infrastructure to disasters. In 2017, the U. S. Environmental Protection Agency and Sandia National Laborator...
Results from the EWRI Summit on the Future of EPANET (PAPER IN NON-EPA PROCEEDINGS)
The Environmental and Water Resources Institute (EWRI) in association with the National Center for Infrastructure Modeling and Management (NCIMM), EPA, and the broad user and open-source software development communities convened an EPANET Visioning Summit in Reston Virginia on Ap...
