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

COURSE DESCRIPTION

This two-part course is the second half of our HEC-RAS Webinar Series. Enroll in the full series to save 15% and earn 4 PDH / 0.4 CEU!

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. The most common mistake we see is related to bridge modeling.

Join Forester University for this live, educational, two-part webinar as returning speaker Dr. David T. Williams (who has taught HEC-RAS and bridge hydraulics to the Federal Highway Administration as well as state and local departments of transportation) presents examples of common geometric mistakes and misunderstandings of bridge parameters using HEC-RAS that could have potentially significant effects on a bridge project’s hydraulic results.

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.

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.

Part I 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

Part II 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
