Online Course: Modelling Structures in HEC-RAS – June 2019

Water modelling for bridges and culverts

This course covers the incorporation of bridges and culverts into 1D, 2D, and coupled 1D/2D HEC-RAS models. Includes up to one hour of optional one-on-one screen-sharing time with the instructor to assist with troubleshooting or to set up or optimise your own project model.

These interactive, mentoring sessions provide a unique opportunity to ask questions as you build a model with your presenter, Krey Price, a highly experienced HEC-RAS user with extensive software development and lecturing experience. His career includes 15 years of developing hydraulic models for the U.S. Army Corps of Engineers.

Topics covered in the live and interactive sessions include:

  1. Background theory: Energy vs momentum for low flow, pressure flow, and weir flow
  2. The HDS5 approach for culvert design
  3. Background theory: Delineating appropriate upstream and downstream 1D cross sections
  4. Estimating flow separation and expansion/contraction zones for ceofficients and ineffective flow areas
  5. Entering bridge geometry for deck, abutments, and piers
  6. Linking a 1D bridge reaches to 2D flow areas
  7. Entering bridges and culverts as internal connections in 2D Flow Areas
  8. Introduction to bridge scour for piers and abutments


  • The course is delivered through 10 units via the learning platform
  • 2 live and interactive sessions of 2 hours over two weeks
    • Thursday, 13 June, 10:30 (Sydney Time)
    • Thursday, 20 June, 10.30 (Sydney Time)
    • Sessions are recorded & uploaded to the learning platform, if you cannot attend live
  • Up to one hour optional one-on-one screen-sharing time with the instructor to assist with troubleshooting or to set up or optimise your own project model.
  • Pre-and-post-course materials to go through via the learning platform.
  • Exercise via a 40 page training manual between the 2 week’s live sessions.

Preparation: Pre-course reading and video watching is encouraged. There is also an opportunity to tailor the sessions to your direct questions via the initial survey. After the first week you will be given some exercises to complete, prior to the next session.

Requirements: A good internet connection and the latest version of HEC-RAS 5.0.5.
