A water rise takes place on down stream of sloping glacis, when a stream of water moving with high velocity and low depth strikes another stream of flow moving with low velocity and high depth, such breakage in water surface is called______________?
Correct answer: C. Hydraulic jump
- A. Water wave
- B. Water tide
- C. Hydraulic jump
- D. Afflux
Explanation
A hydraulic jump is the abrupt transition from shallow, high-velocity supercritical flow to deeper, low-velocity subcritical flow, with considerable energy dissipation. Afflux is instead the rise in upstream water level caused by an obstruction.
