In an open channel, what is the specific term for the abrupt transition from supercritical to subcritical flow, characterized by a sudden rise in water depth?

The specific term for the abrupt transition from supercritical to subcritical flow, characterized by a sudden rise in water depth, is a hydraulic jump. A hydraulic jump is a phenomenon in an open channel where rapidly flowing, shallow water, known as supercritical flow, suddenly converts into slower, deeper water, known as subcritical flow. This transition is accompanied by intense turbulence and significant energy dissipation. Supercritical flow occurs when the flow velocity is high and the water depth is relatively shallow. In this regime, the Froude number, a dimensionless parameter that represents the ratio of inertial forces to gravitational forces, is greater th....
