Chute spillway Chute spillways carry supercritical flow through the steep slope of an open channel. There are four main components of a chute spillway: The elements of a spillway are the inlet, the vertical curve section (ogee curve), the steep-sloped channel and the outlet. In order to avoid a hydraulic jump, the … See more Open channel spillways are dam spillways that utilize the principles of open-channel flow to convey impounded water in order to prevent dam failure. They can function as principal spillways, emergency spillways, or both. They can … See more Chute spillways The flow coming into the spillway is subcritical. The slope of the chute causes the flow velocity to increase. Typically, supercritical flow is maintained in the chute. Stepped spillway See more Every dam needs some form of energy dissipation in its discharge structure to prevent erosion and scour on the downstream side of the dam, since these phenomena can … See more Different agencies have different methods and formulas for quantifying flows and conveyance capacities for chute spillways. The Natural Resources Conservation Service (NRCS) produced handbooks on dam design. In the National Engineering Handbook, Section … See more Cavitation is the formation of a void, such as a bubble, within a liquid.
