A raft guide's primary job is to navigate an inflatable raft with passengers down a river in a safe and enjoyable manner. This requires that they continually assess and manage risks during the trip. A skilled raft guide is able to recognize river features and understand their effects on a raft, and what is required to navigate among or around ...

Studies suggest that environmental efficacy ...

The nature of artificial whitewater courses necessitates the need for a drop in the river, and enough water flow to provide hydraulics. When this isn't possible (often in flat low-lying areas), electric pumps are used to lift and re-circulate the water to the top of the course. The shapes of these courses are commonly circular or U-shaped.
The flowing water makes its way over wooden logs or plastic tubes strapped to the base of the river channel, which disrupt the smooth flow of the water, thus providing the ride with its 'rapids'. Most river rapid rides also feature a wave section, where the river channel widens and a wave machine creates waves at a 90-degree angle to the flow ...
The first whitewater slalom race took place on the Aar River in Switzerland in 1933. [1] The early slalom courses were all set in natural rivers, but when whitewater slalom became an Olympic sport for the first time, at the 1972 Munich Games, the venue was the world's first concrete-channel artificial whitewater course, the Eiskanal in Augsburg.
In high-volume water flows, holes can subtly aerate the water, enough to allow craft to fall through the aerated water to the bottom of a deep 'hole'. Some of the most dangerous types of holes are formed by low-head dams , and similar types of obstructions. In a low-head dam, the 'hole' has a very wide, uniform structure with no escape point ...
