A lazy river is a water ride found in water parks, hotels, resorts, and recreation centers, which usually consists of a shallow (2.5–3.5-foot (0.76–1.07 m)) pool that flows similarly to a river.
[1] There is generally a slow current, usually just enough to allow guests to gently ride along lying on rafts.
The current is generated by means of a gradual slope in the terrain, aided by a pumping mechanism that allows for the river to continue flowing indefinitely.
Torrent rivers appear at all of the Schlitterbahn water parks and Aquaventure in Dubai and the Bahamas.
Water flows similarly to a lazy river but because of the depth can be used for aquatic therapy and swimming or walking against the current.
