I didn't quite understand how you were able to make that work. I was able to make the long culvert work (still testing to see how effective it is for my situation), but I was very curious about utilizing this method to add internal boundary conditions for inflows. Hopefully, a few people with calibrated 1D bridge/culvert models can try this out and share their findings. Wow, what a clever and useful idea! Thanks for sharing, Con (and Chris)! I'd love to about the accuracy of this method, beyond its brute functionality in moving water from Point A to B. sajaad ali soomro on September 28, 2016.Good luck! Give it a try and let me know how it works for you.

Krey Price of Surface Water Solutions wrote a detailed explanation on how to use this technique. He first discussed this in The RAS Solution forum. Con Katsoulas, a senior water resources engineering from SMEC in Sydney Australia came up with a method to get around this limitation. But the current limitation doesn’t allow this.īut we’re in luck! Mr.
If your cell size is relatively small and your culvert is relatively long, then your culvert may in reality span many cells between its upstream side and downstream side. One current limitation in HEC-RAS 5 is that when you put a culvert or gate in a 2D Area Connection, flow through the culvert or gate can only go from a cell adjacent to the 2D Area Connection line on the upstream side to a cell adjacent to the 2D Area Connection on the downstream side. However, “Wormhole Culverts” has to be right up near the top of ingenious workarounds. Whether in a training class, giving technical support, or just simply over discussions with other HEC-RAS users, I still learn new ways to use HEC-RAS almost daily. One of my joys in teaching HEC-RAS to professionals and students around the world is seeing the clever ways that people use and apply HEC-RAS. This is one of the coolest workaround ideas for HEC-RAS that I’ve seen in a long time. Written by Chris Goodell | September 27, 2016
