WebApr 10, 2024 · Sluice gates are common hydraulic structures for controlling and regulating flow in open channels. This study investigates five models’ performance in distinguishing conditions of flow regimes, estimating the discharge coefficient (Cd) and flow rate. Experiments were conducted for different gate openings, flow rates, upstream and … WebThese parameters are; the upstream flow depth, the downstream water depth near the lip of the gate, the tailwater depth (in the submerged flow condition), the gate radius, the gate opening and the ...

WebUpstream, the water surface must rise from a normal depth of 0.97 m to 9.21 m at the gate. The only way to do this on a mild reach is to follow an M1 profile. The same logic applies downstream to determine that the water surface follows an M3 profile from the gate until the depth reaches the conjugate depth of the normal depth at which point a ... Webconstant upstream depth. Figure 2a also indicates that Y2 reaches about 0.1m at Y1 of 0.01m and speciic discharge (q) of 0.01m3/sec/m. Accordingly, igure 2b indicates that the Froude number at the upstream depth boosts as upstream depth declines that can be attributed to the increase in low velocity. On the other hand, an enhancement

WebFor a given gate opening, the following steps summarize the solution process. The limiting upstream water-surface height for FW flow, y 1fw, is determined for the gate opening.
