HEC-RAS 5.0 Benchmarking Study published, "bug fix" Version 5.0.1 released for download 
9 May 2016 Melbourne course attendees update
2D Benchmarking Study Results Published
   
 The draft benchmarking study we discussed during the course lectures has just been published. The final report is now available to download here if you want to have a look at how the new HEC-RAS stacks up against other 2D models.
Hopefully the UK Environment Agency 2D model benchmarking study will be updated soon to reflect the HEC-RAS results.
Do keep in mind that this study only compares models to each other and not to observed results.
Referrals

I'll be back in Melbourne in October teaching a 2D course in conjunction with ICEWARM. The course begins with introductory 1D modelling. 2D components of the course will be held 19-21 October if you have any colleagues who may be interested in attending. 
Click here for more details on the Melbourne course schedule.
 
Registrations are also available for additional courses in Brisbane, Perth, and Sydney. Our Perth course sold out but we have added a second date, so if you happen to have any contacts or colleagues who might be interested, please forward the registration link straight away.
 
We are still compiling expressions of interest for courses to be held in other locations as well, including Hobart, Adelaide, Canberra, Newcastle, and Gold Coast.

 

Keep in mind that anyone you refer directly can receive a $100 discount on the registration fee by using coupon code "referral" at checkout. Members of your own organisation who wish to attend can receive special group discounts. Academic discounts are also available. Contact us for more details or applicable coupon codes.

If you haven't done so already, you may wish to download the new "bug fix" version of HEC-RAS, which has been designated as Version 5.0.1. Be sure to uninstall Version 5.0.0 first. This latest version addresses a couple of the bugs that we encountered during the workshops. 

Hydraulic Structures
   
In response to feedback and questions we received during our recently completed Perth course, one item that will be covered in more detail in future courses will be hydraulic structures. If you have questions on how to add bridges or culverts to your 2D model, please e-mail me.
 
If you'd like to tackle it on your own, check out Chapter 3 of the 2D manual that is accessible through the HEC-RAS Help Menu. Culverts and bridges are covered on Pages 3-63 through 3-65. Currently, HEC-RAS is limited to connecting adjacent cells through an internal connection if a bridge or culvert is added to a pure 2D model without 1D reaches.
 
Bridge openings can be "faked" in by using a gate or series of box culverts, provided the bridge deck along the alignment is reflected in the terrain data or the terrain is lifted to represent the bridge deck or roadway surface. Keep in mind that the adjacent cells at the inlet and outlet would need to be lowered as well. The limitations are expected to be removed in future versions, but for now there are a few workarounds that will still get the job done. 
Customised courses
 
We would be happy to customise a course for your organisation. Customised courses can be very cost-effective (hourly consulting fee only) and can maximise the return on the time invested by your staff by providing only the targeted content that is relevant to your organisation. Targeted courses might focus on d am breach, 1D bridge elements, floodplain risk assessments, water quality studies, sediment transport, bank erosion modelling, development impacts, WSUD, hydraulic structures, coastal and marine environments, TUFLOW model conversions, reviewing consultant deliverables, etc. Please e-mail us to discuss a proposal.
