In HEC-RAS 5.0 can you model a bridge inside a 2D Flow Area? I see examples on levees, lateral connections and dams, but no one successfully placing a bridge inside the 2D area.
Have you found any answers to your question? I’ve found you can only model a bridge as a weir/culvert combination. It would be nice if they could add bridge functionality in future releases. I haven’t heard anything though.
According to the latest Manual, April 2015, Page16,
Cannot use the HEC-RAS bridge modeling capabilities inside of a 2D flow
area. You can do culverts, weirs, and breaching by using the SA/2D Area
Conn tool.
