In high-volume water flows, holes can subtly aerate the water, enough to allow craft to fall through the aerated water to the bottom of a deep 'hole'. Some of the most dangerous types of holes are formed by low-head dams , and similar types of obstructions. In a low-head dam, the 'hole' has a very wide, uniform structure with no escape point ...
Ekman pumping - Ekman Pumping is the component of Ekman transport that results in areas of downwelling due to the convergence of water; Haida Eddies - episodic, clockwise rotating ocean eddies that form during the winter off the west coast of British Columbia; Mesoscale ocean eddies - Swirling in the ocean created by its turbulent nature

The fall of water where the stream goes over a sudden drop called a knickpoint; some knickpoints are formed by erosion when water flows over an especially resistant stratum, followed by one less so. The stream expends kinetic energy in "trying" to eliminate the knickpoint. Wetted perimeter
A whirlpool is a body of rotating water produced by opposing currents or a current running into an obstacle. [1] [clarification needed] Small whirlpools form when a bath or a sink is draining. More powerful ones formed in seas or oceans may be called maelstroms (/ ˈ m eɪ l s t r ɒ m,-r ə m / MAYL-strom, -strəm).
