Hydrodynamic Forces on High-Head Gates
What effects do intake geometry and approach flow conditions have on hydrodynamic forces for high-head gates
Need and Benefit
Due to aging infrastructure and changing operating requirements, much of Reclamation's infrastructure will continue to see the need for extensive modifications or new designs as well as analyses to ensure existing designs can function under new operating conditions. For high-head gates, this will require an improved understanding of the hydrodynamic forces for various configurations and geometries. The research documented by Naudascher (1991), which provides design guidance for relatively simple geometries can be extended to include additional intake geometries and approach flow conditions upstream of the gate for accurately predicting hydrodynamic forces.
