In this system head control devices are needed to regulate the discharge through the tunnels and the appurtenant structures. For this purpose gated control structures open to the atmosphere were chosen. The gate structures were circular in plan and fitted with gates for flow control. The research described in this report was carried out to study in detail the hydraulic characteristics for a wide variety of flow conditions for one of these structures, the Morris Reservoir Turnout Structure.en-USReport
