HEC-RAS Webinar Series

COURSE DESCRIPTION

HEC-RAS is a rather complicated 1-D and 2-D hydraulics program that can be easily put together but also easily—and unknowingly—misused. And yes, even subtle misuses can have potentially significant effects on a project’s hydraulic results.

But former HEC staffer and expert HEC-RAS user Dr. David T. Williams is here to help…Join him for Forester University’s HEC-RAS Webinar Series!

This comprehensive, four-session series consists of 2 two-part webinars during which Dr. Williams will provide examples of these subtle misuses of HEC-RAS, including common geometric mistakes and misunderstandings of bridge parameters. Course material will be based upon Dr. Williams’ review of submitted models, his discussions with experienced users, his blogs on hydraulic and bridge modeling topics, and his HEC-RAS Steady and Unsteady course lecture notes.

Read brief course descriptions below, follow the links to learn more, and register today—a la carte or for the entire series. All sessions become available on-demand within 24 hours of airing live, so it’s never too late to save 15% and earn 4 PDH / 0.4 CEU with the full-series bundle!

Avoid Costly Mistakes Using HEC-RAS: Geometric Misrepresentations & Understanding Computations

2 PDH / 0.2 CEU
Part I will discuss geometric misrepresentations and misconceptions about how HEC-RAS performs its computations on the geometric layout. Part II will detail how HEC-RAS performs its computations and how to properly configure HEC-RAS to simulate real-world phenomena.


 

Bridge Modeling Using HEC-RAS: Building the Model & Modeling Guidelines

2 PDH / 0.2 CEU
Part I will discuss geometric misrepresentations and the proper placement of cross sections within an HEC-RAS model to properly simulate the hydraulic effects of a bridge. Part II will detail how some of the input parameters should be determined and where within the model they should be placed.

Session I Learning Objectives:

  • Learn how to avoid the subtle mistakes presented
  • Understand the thought process going from existing to project conditions
  • Appreciate the use of graphics for reviewing HEC-RAS models
  • Recognize the symptoms of a faulty HEC-RAS model
  • Determine what is and is not “allowed” in HEC-RAS modeling

Session II Learning Objectives:

  • Learn how HEC-RAS does its computations for various hydraulic conditions
  • Determine what options to invoke for each type of hydraulic phenomena
  • Know the relative magnitude of error that is generated going from one option to another
  • Understand the proper sequence for reviewing HEC-RAS models
  • Appreciate how project limits, model limits, and study limits are different

Session III Learning Objectives:

  • Learn the types of flow through bridges
  • Understand bridge terminology and relation to HEC-RAS
  • Recognize the reason for initial placement of the four cross sections to model a bridge
  • Determine initial expansion and contraction coefficients
  • Know the proper placement and elevations of ineffective flow areas
  • Understand types of flow computations in HEC-RAS
  • Learn the step-by-step creation of a bridge model in HEC-RAS

Session IV Learning Objectives:

  • Know refinement of expansion and contraction coefficients
  • Determine weir coefficients and submergence corrections
  • Understand placement refinement of the four cross sections to model a bridge
  • Understand the details of the various bridge hydraulic methods in HEC-RAS and when to use them
  • Learn how to check for flow consistency of a bridge model
