A hydraulic jump occurs in an open channel when the slope of the channel changes from ______.

MILD slope to STEEP slope
STEEP slope to MILD slope
MILD slope to ZERO slope
STEEP slope to a STEEPER slope

Correct answer: STEEP slope to MILD slope

Solution

A hydraulic jump occurs when the flow transitions from a high-energy state, typical of steep slopes, to a lower-energy state associated with mild slopes, resulting in a sudden change in flow characteristics.
