In fluid dynamics, an eddy is the swirling of a fluid and the reverse current created when the fluid is in a turbulent flow regime. [2] The moving fluid creates a space devoid of downstream-flowing fluid on the downstream side of the object.
The name "Bilgola" is derived from an Aboriginal term Belgoula meaning "swirling waters", or perhaps "a pretty beach with steep slopes, studded with cabbage palms". [2] The word Belgoula was noted in Surveyor James Meehan's records of 1814. Robert Henderson received a grant of 100 acres (0.40 km 2) in 1822 which he named "Belgoola". The ...

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).
The nature of eddies are such that the center of the eddy, the outer swirling ring, and the surrounding waters are well stratified and maintain all of their distinctive physical, chemical, and biological properties throughout the eddy’s lifetime, before losing their distinctive characteristics at the end of the life of the cold core ring.
Just as three consecutive La Niñas finally stop affecting global weather patterns, conditions in the swirling waters of the Pacific Ocean strongly suggest an El Niño could arrive in the coming ...
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 ...
The river's English name is due to the large number of large rounded holes (kettles) in the sandstone in and around the river, carved out by the swirling waters of the river. The river's Dakota name Céġa watpa [2] entered into English via the Anishinaabe people's Akiko-ziibi, both meaning "Kettle River". [3]
