Flood Frequency: Calculating 100-Year Floods

Everyone knows that a 100-year flood is a really big flood. But not all big floods are 100-year floods, and a 100-year flood is not necessarily the same as a 100-year storm. So…how can you ensure your floodplain structures are designed to handle any flood nature may have in store?

Join returning speaker Doug Beyerlein, P.E., P.H., D.WRE, in our online training webinar as we examine the different flood frequency methods available to an engineer, the key assumptions contained in each method, and how to select the appropriate flood frequency method for the engineering job at hand. We’ll also discuss situations where flood frequency is not the appropriate design parameter and what flow-related method should be used instead.

Specifically, we’ll discuss how engineers use flood frequency as a design standard in sizing many, if not most, structures within a floodplain—ranging from designing culverts and bridges, to determining roadway and building elevations, to sizing flood control structures. Calculating a flood frequency value is not difficult, but selecting the appropriate flood frequency method to calculate the frequency flow value can be.

Learning Objectives
Attendees can expect the discussion and education of the following learning objectives.

  • Understand why flood frequency is not the same as storm frequency.
  • Explore the different methods for calculating flood frequency.
  • Analyze the key assumptions built into each flood frequency method.
  • Learn the regional hydrologic characteristics that are important in flood frequency method selection.
  • Determine when flood frequency is not the appropriate design parameter.

Webinar: Flood Best Practices – Protecting People and Property with GIS

This webinar, which is available live and on demand, is one of the free webinars offered by Forester University.

Sponsored by one of our suppliers of GIS materials, ESRI, attendees can expect the discussion and education of the following learning objectives:

  • Learn how to transition your flood control systems from paper to Web GIS
  • Gain GIS real-world best practices, and how you apply these to better manage your flood control system performance
  • Understand how to use GIS to post flood event response, and gather documentation to recover disaster-related funds and justify post-environmental clearance requirements
  • Get a preview of next generation flood management solutions, and learn how you can use web GIS technology to modernize your existing systems
