What’s the equation used by Hec Ras to solve the flow through a Radial Gate (Variables: Trunnion Exponent, Openning Exponent, Head Exponent, etc. ) – Radial Methodology. I think there is a bug there, because when I calculate it manually I realize that “discharge coefficient” is 1.35. Any reference or book ?
Wanted to follow up and see if you figured this out. I am having an issue myself with figuring out a possible bug in how RAS calculates flow through a radial gate as the ratio of tailwater to headwater energy depths transitions past 0.67 (the threshold by which RAS supposedly alters how it calculates flow through a radial gate.
