Abstract
Submerged weir flow is one of the most difficult flow conditions to accurately predict at gated spillways. Previous research work has mostly focused on submerged weir flow measured in small-scale laboratory models. In this paper, we develop a submerged weir flow equation based on field measurements collected with an Acoustic Doppler Current Profiler at several prototype gated spillways in southern Florida. The proposed method is developed using dimensional analysis. This method is compared with field measurements and several previously published submerged weir equations.
