If you’re in the neighborhood, or just want a nice trip to Australia, consider taking this excellent course in 1D/2D Modelling using HEC-RAS the week of 4 June, 2018, hosted by ICEWaRM and the Australian Water School. This will be a great opportunity to get some training on the new features just introduced in the […]

Take a look at the water surface profile in Figure 1 below. The two profiles are for Class A low flow (subcritical throughout) with identical boundary conditions, flow conditions, and geometry. The only difference is the bridge modeling approach: the blue line is calculated using the energy method; the red line is calculated using the […]
A fantastic blog post by Mr. Juha Aaltonen of the Freshwater Centre of Finnish Environment Institute SYKE. In his post, Mr. Aaltonen discusses river ice breakups and the advantages of incorporating uncertainty into river ice modeling in HEC-RAS. He was able to do this by harnessing the power of the HECRASController as detailed in “Breaking […]

This forum was developed for those who use HEC-RAS to simulate river ice covers and river ice jams. Please post your questions, comments, and […]
I’ve been seeing some cool applications of HEC-RAS from around the world lately. Here are some articles showing a few ways we’ve been putting HEC-RAS to use down under. Making Middle Zealand Did you know that the only thing keeping New Zealand’s two main islands from being split into three is a little 2-km wide […]
New geospatial editing tools are currently in development for the next version of HEC-RAS-Version 5.1. While no date has been set for the release of Version 5.1, it is expected sometime within the next year or two. But no guarantees! This will be an exciting new addition to HEC-RAS in that users will no longer […]
A recent question was posted on the HEC-RAS blog regarding the optimal shape of the SA/2D Area Connection alignment for a wormhole culvert – in particular, whether a “Z” shape or “S” shape would be preferable. My apologies in advance for the drawn-out response, but I’ve had this question come up a number of times in class and […]
JBA Consulting will be hosting another HEC Software Workshop this summer. Back for 2017 25 – 27 JulyCCT Venues, Barbican, London EC1 This is the second software workshop in Europe dedicated to the HEC hydraulic and hydrological modelling software – HEC-RAS, HEC-HMS, HEC-DSS and HEC-ResSim. We are working with the team at Hydrologic Engineering Center plus other […]
Lately, I’ve seen a lot of basic bank station issues for models I have reviewed. Some real basic stuff. So I thought it would be good to go back to the basics a bit here and review proper placement of bank stations for cross sections in HEC-RAS. What do bank stations do for us? First […]
Version 5 of HEC-RAS allows the use of rating curves for inline structures (and lateral structures). Rating curves can be added through the Outlet RC feature in the inline structure editor. Inline structure rating curves can be useful for evaluating the impacts of structures, such as labyrinth dams, where it may be difficult to correctly […]
