TI  - Discharge Coefficients for Radial-Gated Ogee Spillways
by Laboratory Data and by Design of Small Dams
AB  - Using the measured data on 15 laboratory models in USA, six models and one prototype in
Turkey, the discharge coefficients (C’s) of radial-gated ogee spillways for various gate
openings and lake water surface elevations are computed. Comparison of these C’s for 22
spillways with the ones given by Figure 9-31 of Design of Small Dams does not show close
agreements. It is determined that C depends on both the angle Ɵ and the ratio d/H1, rather
than Ɵ only where d and H1 are the gate opening and the upstream head, and statistically
significant regression equations are computed individually for each one of 22 cases.
