Water modeling basics


    The U.S. Environmental Protection Agency’s (EPA’s) Water Modeling Workgroup has hosted a series of free webinars to help water quality professionals better understand surface water quality modeling and how models can be used to solve common problems that face water quality regulators. The webinars are focused on modeling as it applies to the Total Maximum Daily Load (TMDL), Standards, and Water Quality Permitting Programs, but they are applicable to a wide range of audiences.

    These two-hour webinars cover modeling basics such as selecting, developing, and running hydrology and water quality models to modeling specific pollutants and parameters (e.g., nutrients, sediment, and metals), specific types of models, and emerging issues in water quality modeling. Webinars currently available include:

    • Water Quality Models 101 — What Are These Things?
    • Brick by Brick: How Water Quality Models are Developed
    • Interpreting and Using Water Quality Models
    • Nooksack River QUAL2Kw Temperature Model and Climate Change Scenarios
    • Modeling Nutrients: Nutrient Cycles, Potential Impacts on Water Quality, and Developing Nutrient Endpoints
    • Modeling Nutrients in Rivers, Streams, Lakes, Reservoirs, and Estuaries
    • Sediment Modeling — Part 1
    • Sediment Modeling — Part II
    • Modeling Dissolved Oxygen
    • Watershed Modeling Using Hydrological Simulation Program – FORTRAN (HSPF)
    • Introduction to Environmental Fluid Dynamics Code (EFDC)
    • Introduction to Soil and Water Assessment Tool (SWAT)
    • Introduction to Water Quality Simulation Program (WASP)
    • EPA’s Stormwater Management Model (SWMM)
    • Introduction to EPA’s Watershed Management Optimization Support Tool (WMOST) v3

    Webinars are recorded and archived on EPA’s website at www.epa.gov/waterdata/surface-water-quality-modeling-training.
