River surfing is a water sport that involves riding on the surface of a river's waves, similar to traditional surfing in the ocean. Surfers use a surfboard to navigate the standing waves created by the river's current, which can be found in various locations around the world. These waves can be formed by natural features like rocks or man-made structures such as weirs. Unlike ocean surfing, river surfing allows surfers to ride the same wave for an extended period, as the water continuously flows. This sport requires specific skills, including balance and paddling techniques, and is often practiced in rivers with consistent flow and suitable wave conditions.
