Surface Water Quality Modeling Training

EPA’s Water Modeling Workgroup (WMW) sponsors an ongoing series of two-hour webinars to help water quality professionals better understand surface water quality models and how they can be used to address water quality problems. Under An Introduction to Water Modeling, the first three webinars cover modeling basics such as selecting, developing, and running hydrology and water quality models. Subsequent webinars focus on modeling specific pollutants and parameters (for example, nutrients, sediment, metals), specific types of models, and modeling at different scales.

Topic and Description


An Introduction to Water Modeling
For general information on modeling
Water Quality Modeling
Particularly at medium scales, such as a single river, lake, or reservoir
Dissolved Oxygen
Modeling Frameworks
Land Use and Watershed Modeling
Possible at larger watershed scales, such as the upper Mississippi basin

Upcoming webinars

Using the Water Quality Simulation Program (WASP) to Simulate Toxicant Concentrations in Surface Waters and Sediments

EPA’s Water Quality Analysis Simulation Program (WASP) is a differential, spatially-resolved, mass balance, fate and transport modeling framework structured to allow users to simulate concentrations of environmental contaminants in surface waters and sediments. Specific case-study applications of the WASP Advanced Toxicant Module will be presented to provide real-world examples.

Updates to EPA’s Storm Water Management Model (SWMM)

This presentation will be an update to the February 2018 WMW Webinar “Introduction to SWMM”. EPA’s Storm Water Management Model (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 drainage systems in urban and non-urban areas.  SWMM is a dynamic hydrology-hydraulic water quality simulation model. It is used for single event or long-term (continuous) simulation of runoff quantity and quality.
