HEC-RAS: spillway approach height for overflow gate
Thank you for your suggestion. You are right, of course, in that if all else fails I could use a user-defined curve. However, the whole point of the Rehbock equation (and the beauty of a sharp-crested weir ;)) is, that I can dynamically calculate a relatively precise weir coefficient without...- MarkusV

HEC-RAS: spillway approach height for overflow gate
Hello everyone, I am trying to model a simple (open top) overfall weir in HEC-RAS 4 (e.g. a stop log weir). HEC-RAS can handle sharp crested overfall gates like this with the Rehbock equation. The weir coefficient according to Rehbock needs the weir height ("spillway approach height" in...- MarkusV
