A circular water current, also known as an EDDY, is a swirling motion of water that can occur in rivers, oceans, and other bodies of water. Eddies are created when the flow of water is disrupted by obstacles such as rocks or other objects. They can also be caused by changes in the direction of the wind or the tide. Eddies can be small or large, and they can move in either a clockwise or counterclockwise direction. They can also be short-lived or long-lasting. Eddies can have a significant impact on the environment, affecting the movement of fish, sediment, and other materials.
