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.

Abstract

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.
