| Abstract |
In this study, capability of an air slot in a siphon spillway for controlling outflow discharge is investigated through hydraulic experiments. Arc and rectangular shapes of air slot are considered and the open area of air slot can be varied. Complex air-regulated flow occurs inside of the siphon spillway when the air slot is installed on it. The same discharge is measured at the same water level inside the reservoir when the water level rises or falls. Nondimensional discharge through the siphon spillway decreases as nondimensional open area of the air slot increases when head differences and water levels of reservoir are constant. The hydraulic experiments show that the control of outflow discharge of siphon spillway is possible by controlling the open area of the air slot. |
