For both model runs, the pressure method was selected as the bridge modeling methodology since the culvert is submerged but does not overtop the roadway. The velocities are higher for the smaller culvert in the vicinity of the bridge. I guess this has to be due to the flow trying to squeeze...
Absolutely nothing changed. All I did was literally cut and paste the new coordinates for the new rise height, and then hit compute. The roadway does not even come close to overtopping in either scenario. Both are under pressurized flow, basically acting as sluice gates. I am modeling as a...
I am modeling a proposed ConSpan culvert crossing in HEC-RAS 3.1.2. I have input a 32' span by 8' rise ConSpan culvert into the HEC-RAS bridge editor (i.e. I input the coordinates of the ConSpan in the bridge section, not the culvert section). I setup the ineffective flow, etc. for the 32' x 8'...
