Abstract:
Severe cavitation damage occurred to concrete in the outlet works at Stampede Dam during flood control releases in the 1982 runoff season. Air slots installed to reduce cavitation damage potential performed poorly during the 1983 runoff season, so a model study was conducted. From the model study, an air slot was designed that provided sufficient air to the flow boundary interface under the high tailwater conditions encountered.
