WebApr 13, 2024 · The depth of the downstream still water was h 0 = 0.1 m, and the investigation of tsunami force characteristics was conducted by varying the upstream reservoir water depth and deck height. As shown in Figure 13 a, when the relative wave height was h 2 / ( Z d + h ) ≤ 1 , the tsunami wave height was below the top of the bridge … WebThe theoretical evaluation was tested against hydraulic lab ... The main purpose of most control gates is to maintain a constant water depth upstream so that orifice-based ofltakes, usually located just upstream of the gates, will deliver water at a near-constant rate regardless of the flow rate in the main canal. The control gates themselves ... WebSince the preferred (i.e. normal) depth is subcritical, there must be a downstream hydraulic jump. (A quick calculation shows that the upstream depth for this jump is greater than ℎ2, so there is indeed a length of GVF between the area of bed rise and the jump.)

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. The FW flow is assumed to just touch the gate lip, that is, y 2 = h g. The upstream water level required to produce the FW flow is computed from equation 108. WebIf the discharge remains constant but for a larger gate opening, the upstream depth is smaller and the downstream flow depth is larger.
