Hydrodynamic Interactions at Multi-Gated and Dual Spillways
Publication: World Environmental and Water Resources Congress 2024
ABSTRACT
This study employed computational fluid dynamics (CFD) to investigate hydrodynamic interactions at multi-gated and dual spillways. When spillways with multiple gates or multiple spillways in proximity share the same headwater pool and discharge into a common downstream area, their interactions can significantly influence their flow dynamics. This research focuses on understanding how these interactions can affect the actual discharge, which may differ from the theoretically combined singular operation discharge of each gate or spillway. Discharge through a six-gated spillway S-65E in the Kissimmee River and dual spillways S-333 and S-333N in Miami-Dade County were simulated using CFD. Through numerical modeling, it was discovered that multi-operation scenarios, where more than one gate at a spillway is in operation, or dual spillways operate simultaneously, can lead to a reduction in conveyance capacity of the spillways with potential implications for flood control, water supply management, and hydraulic operations. In some cases, this reduction can be as much as 5%, highlighting the importance of considering hydrodynamic interactions in spillway design and operation.
