What Causes Whirlpools in Rivers - MyWaterEarth&Sky
Whirlpools in rivers are caused by irregularities in the riverbed, constrictions, and differential current speeds. Eddies form as water encounters obstacles, creating swirling currents that intensify into vortexes. These dynamic water movements shape river ecosystems and influence sediment transport.
Whirlpool - Wikipedia
In narrow ocean straits with fast flowing water, whirlpools are often caused by tides. Many stories tell of ships being sucked into a maelstrom, although only smaller craft are actually in danger. [2] . Smaller whirlpools appear at river rapids [3] and can be observed downstream of artificial structures such as weirs and dams.
