Live Course: Dam Breach with HEC-RAS

Modelling dam breaches and downstream impacts

Recent dam failures and updated guidelines highlight the need for continuing education around the governing principles of dam breach analyses. Ongoing improvements in both hardware and software allow increasingly detailed models that still require proper input selection to provide meaningful results that improve public safety.

In this course you will learn to build, run, and animate dam breach models from scratch using the free HEC-RAS software. Consisting of three, two-hour interactive mentoring sessions over a three-week period, you will be provided with the unique opportunity to ask questions as you build a model alongside your expert presenters.

Places are limited to allow for greater interaction. Register quickly to secure your place! Live sessions will be recorded and provided to all that cannot attend.

  • The course is delivered through 12 units via the learning platform
  • 3 live and interactive sessions of 2 hours over 3 weeks:
    • Thursday 9 September, 10:00am (Sydney Time)
    • Thursday 16 September, 10:00am (Sydney Time)
    • Thursday 23 September, 10:00am (Sydney Time)
    • Sessions are recorded & uploaded to the learning platform (within 24hrs after session), if you cannot attend live.
  • Workshop guide manual and example data files to complete exercises on your own time in between the live sessions.
  • Pre-and-post-course materials to go through via the learning platform.

Topics covered include

  • 1D vs 2D vs 3D theory for dam breach
  • Level pool vs. dynamic reservoir drawdown
  • Adding a dam as a 1D reach or inline structure
  • Selecting dam breach parameters
  • Setting up and running a dam breach model
  • Diagnosing and troubleshooting a dam breach model
  • Model calibration and sensitivities
  • Exporting inundation and flood wave arrival results


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.

What’s Included

The HEC-RAS Training Series is designed to be taken individually. Each course is highly practical and hands-on ie; not simply a PowerPoint of lectures.

To provide the best desired learning outcomes, setup in a quiet space with dual monitors (ie one screen with the session and the other with the software/exercise that attendees can work on simultaneously). The courses are not designed for a board-room setup.

  • x3, 2-hour sessions and the recordings to view as many times as required in a month;
  • Ability to ask questions to the presenters at anytime through the live session or learning platform;
  • PDF manual of the course. The manual is recommended for ongoing use;
  • Working models, downloaded from the learning platform before starting the course;
  • Exercises / homework to complete between sessions;
  • Pre-reading and viewing materials;
  • Ability to access all the online course materials for a month. The pre-readings and manual are available for ongoing learning;
  • Attendees earn 9+ CPD hours/points (ie with Engineers Australia), 40+ hours for the Series.

Requirements: A good internet connection and the latest version of HEC-RAS. Please note: HEC-RAS Version 5.0.4 and newer will only run on 64-bit Windows operating Systems (including 64-bit versions of Window 7, 8.0, 8.1 and 10). Make sure your operating system is up-to-date with all Microsoft patches for your version, before trying to install HEC-RAS.

Completion: On completion of the course attendees will be issued with a Certificate of Participation.
