Watery swirls, also known as EDDIES, are swirling currents of water that can form in rivers, oceans, and other bodies of water. They are created when the flow of water is disrupted, such as when it encounters an obstacle or changes direction. EDDIES can be small or large, and they can move in either a clockwise or counterclockwise direction. They can also be powerful enough to cause erosion and other damage to the environment.
