Steve Hughes, Senior Analyst, tells us how he uses the free HEC-RAS software on his projects and what his clients think of it.
How do you use the HEC-RAS software?
I have used HEC-RAS for a range of purposes. We use the 1D/2D capabilities as part of scour assessments and scour protection design projects. It gives us reliable estimates of design flow depths and velocities.
I have also recently used the 1D/2D functions to look at floodplain inundation and floodplain depth/velocity/volume as part of flood risk assessments.
Within these studies we examined the impact of raising existing flood embankments on flood risk to the site and elsewhere in the catchment.
Why do you choose to use it over other software?
I’m very familiar with HEC-RAS and find it very easy to set up a model (even in 1D/2D). The reference and user manuals are excellent and the error reporting is also very useful in fixing errors and troubleshooting. Plus, it’s free!
What are your favourite features?
RAS Mapper and the new dereferencing tools make floodplain mapping in 1D or 1D/2D very simple – basic model setup can be achieved in a short time.
What interesting projects have you used it on?
Loads! Floodplain inundation studies, flood risk assessments, culvert design projects, scour related projects. A recent client was very impressed with the clarity of the outputs and the animations.
Want to know more?
Join us in London on 25-27 July for our European HEC Software Workshop. You can buy tickets for just the one day workshop or just the two-day course. Better still, why not join us for both the workshop and the course and immerse yourself in the world of HEC-RAS.
The HEC-RAS software developers are coming over from the Hydrologic Engineering Center to facilitate the day. This gives you the best insight possible into how the software could benefit your projects going forward.
