B)a super-critical flow strikes against a sub-critical flow
C)the two flows of super-critical velocity meet each other
D)the two flows of sub-critical velocity meet each other

Question

Quizplus · Accepted Answer

A hydraulic jump occurs when a super-critical flow (high velocity, shallow depth) transitions to a sub-critical flow (low velocity, greater depth), typically after encountering an obstacle or a change in channel slope.
