Here is an answer from HEC for why the bridge modeling skew option only goes up to 45degrees:
"Water will end up "turning" to go through openings, so HEC-RAS contends that even if a bridge is skewed more that 45degrees to the river, the opening water sees will an opening no less that if the...
Thanks so much for your insight. I've uploaded some pics that will paint the whole picture more clearly. You'll notice that there are several bridges very close to each other.
I wanted to make sure i was correct. The skew angle in my case is 51deg (to be exact, 90-39), per my first exhibit. Its...
See attached pdf. I have a new railroad bridge with a 50deg skew to the flow lines. I assume the skew option in the Bridge editor only modifies your geometry. With this in mind I input my geometry as is (projected onto a plane perpendicular to flow), since the skew option will only let me go...
