Question

Quizplus · Accepted Answer

The phenomenon described in the question is a hydraulic current, also known as a hydraulic jump. This occurs when water flows over a dam or other obstruction and is pulled back in by the undertow or suction effect, resulting in a turbulent rolling boil of water. A rip current is a strong narrow current that flows away from the shore, while a pillow refers to the gentle swelling of water that occurs behind a boat or other object moving through water. A high-head dam is a type of dam that has a large drop in elevation from the upstream to downstream side.
