What is the cause of eddy?

The circular movement in the sea which others call "whirlpool" may cause fear to swimmers. Why is this so? Is this a frequent occurrence in one area because something abnormal is down there?

Separate topics with commas, or by pressing return. Use the delete or backspace key to edit or remove existing topics.

You can leave an optional "tip" with Mahalo's virtual currency, Mahalo Dollars. If you are asking a difficult question that might require some research, or if you'd like a wide variety of feedback, a higher tip often leads to more answers to your question.

And eddy, in both air and water currents, is caused either by the air or water moving over an uneven surface...like rocks at the bottom of the river, or by something moving thru the material...like the eddies that are formed behind a Boeing 747 as it flies (also called wake turbulence).

An eddy is caused when a fluid passes an obstacle. The swirling fluid can set up a reverse current on the downstream side of the obstacle, so that there is a calm area with no downstream moving fluid.
