Online Course: Dam Breach Modelling with HEC-RAS

Advancement in tools allow more efficient production of inundation data than ever before

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. Certification of continuing professional development (CPD) hours will be provided to all course attendees.

Date: Tuesday, 3 December 2019 - Tuesday, 10 December 2019

Time: 11:00am (Australia/Sydney; find your local time)

– The course is delivered through 12 units via the learning platform
– 3 live and interactive sessions of 2 hours over three weeks:
       – Tuesday 26 November, 11:00am (Australia/Sydney Time)
       – Tuesday, 3 December, 11:00am (Australia/Sydney Time)
       – Tuesday, 10 December, 11:00am (Australia/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.
– Also 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.

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

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).

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

Previous attendees comments of HEC-RAS Courses: 
“The explanation on how things work behind the user interface was very helpful”
“These online courses are a great, low-cost format, and would be happy to do more of these.”
“Both the 1D & 2D Courses have been very helpful for me. Thank you”
“The highly interactive nature of the session, allowing time for questions but also proceeding at a decent speed.”
“The ability to interact as required via chat was hugely beneficial. The clarity of instruction was excellent.”
“I found going through the all the exercises together was very useful. It has become really easy to replicate what I learnt in the session for my projects.”
