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 slope of the spillway must be steep enough …
