The investigation of side-weir siphons flow along a curved channel
Side weirs are being used commonly in irrigation, field drainage, sewage systems,side channel spillway dams and settling basins to supply needed discharge or put awayexcess discharge without giving harm to the environment. In this study, self-primingsiphon was used instead of side weir. Settled in the different angels (300, 600 and 900)of a curved channel and flat side (00), water level and velocity were measured byopening and closing of the regulating level gate in different discharges and levels. Atthe result of these measurements, water surface profiles and depth averaged velocitieswere found and shown in figures. Froude numbers, siphon spillway discharge anddischarge coefficients were calculated. In addition, siphon spillway and priming,depriming and helicoidal flow were investigated.
