Adding an Internal Structure to a 2D Mesh in HEC-RAS

Thank you for this. That last bit about the checking the cell elevation that the structure is connected to helped me solve the error on my model.

Thank you very much doctor. It would be very interesting to carry out an analysis for bridges with SA/2D connection with a flow that passes under the bridge deck, many times it generates a very large backwater upstream of the bridge, forcing me to enter the pillars and abutments of the bridge as modifications. of terrain in RasMapper. I'm sure I'm making a mistake in entering the data, it would be interesting to see it from your perspective. Thank you very much for your attention doctor.

Awesome quick tutorial! Measuring and copying the coordinates was a game changer thank you

I love the ability to add culvert barrel GIS data to connect cells away from the structure centerline. It would be great if structure breaches had this same ability. Large dam embankments and smallish cell sizes don't play nice

Thank you for your comprehensive explanation.

@Stanford Gibson, Hello! Great content as always. Dear Gibson, where I can report a minor error I have been getting on the new version of the Hec-ras. The new 6.4.1 version is giving an error when starting the water quality simulation, saying that the preprocessed geometry could not be found, it only happens on the non-permanent flux. Best regards and keep up the top tier work.

Thanks for looking for more such videos

It shows culvert elevation is below the terrain. In your case it would give this error as well as it can be seen the bottom of the culvert is below the terrain elevation. How do you fix that?

Thank you for the video. When you copied the coordinates into the barrel GIS data, did that change the length of the culvert?
