HEC-RAS Profile

[MrBdo]

I have modeled a box culvert as a bridge using only the deck/roadway editor. I have listed my points within the editor and everything looks OK as far as the cross sections. I take a loot at the profile and see that the flows that are overtopping are going through the roadway instead of completely over. I'm sure it's something simple. Can anyone help?

You need to attach the geometry file at the very least. I'm guessing that your low chord values at the center of the bridge are higher than along the side, creating an opening on the center for the water to go through.
