Swirling water is a type of water movement that occurs when a current or tide creates a circular motion. The term EDDY is used to describe the swirling water, and eddie is an alternate spelling. Eddies can be found in rivers, oceans, and other bodies of water. They are often caused by obstacles such as rocks, plants, or other objects that disrupt the flow of the water. Eddies can also be created by wind, which causes the water to swirl in a circular pattern.
