I have a bridge to model in HEC RAS that has a bend in it. Apparently, the road had been widened years ago and the added portion of the bridge had to be put on a slant to avoid conflicts. So the result is a bridge that is perpendicular to the roadway up to the median, then the rest has a 20-degree-from-the-vertical slant. I've seen culverts like this before, but I never modeled one in HEC RAS - I've only done HGL calcs for drainage design for this type. I know there are some bend losses to consider, but when using a bridge, HEC RAS doesn't do losses, does it? I did find a way to enter my own orifice coefficient and calculate this including the bend losses.
Or I could model it as a buried culvert. Two buried culverts? - one for each section and then put no distance between them.
