Plunge pool

From Wikipedia, the free encyclopedia

A plunge pool is a pool, lake, or pond that is small in diameter, but deep. The term can also refer to a small deep swimming pool used to cool off.

Another type of plunge pool is formed under a vertical displacement of water, for example a waterfall or rapids. Because of the hydraulic action acted there, the plunge pool interiors are irregular and rough. Plunge pools are created by the presure of the water either from a waterfall or rapids. the water swirls around fallen rocks and gradually makes a deep pool.

Also a plunge pool is created becuse of vertical erosion taking place underneath a waterfall
