Water Whirling is a phenomenon that occurs when water moves in a circular motion, creating a vortex. It is often seen in rivers and streams, where the water is forced to move around an obstacle such as a rock or tree root. This creates a swirling effect, which can be seen from the surface of the water. EDDY is a term used to describe this type of water movement. It is caused by the interaction between the water and the object it is moving around, and can be seen in both fast-moving and slow-moving water.
