An "eddy" in river dynamics refers to a current that flows in the opposite direction of the main flow of the river. Eddies form when water encounters an obstruction, such as a rock or the riverbank. This obstruction disrupts the main flow, causing some of the water to swirl back upstream in a circular motion. This countercurrent can create areas of turbulence and can affect navigation, fishing, and other activities on the river.

Recognizing the role of eddies is crucial for anyone involved in swiftwater rescue or water navigation, as they can provide opportunities for safer passages or zones to rest and regroup when traversing fast-moving waters. Understanding how eddies function allows rescuers to better plan their movements and positions during a rescue operation.
