Some rapids become more technical and more difficult at lower water levels. Second, the classification system does not take into account the type of boat being paddled.
Some rapids may present particular challenges for rafts, while other rapids may be more difficult for a whitewater paddler in a kayak. Finally, major events like landslides, ice storms or floods can change the shape of rapids, thus altering their classification. The bottom line is that assigning numbers to rivers is inherently subjective. Rivers are a natural force subject to change at anytime.

Whitewater Classification System from flat moving water to not advised to run chaos. The classification system for whitewater rivers is not an exact science.
At Wet Planet, we use the following internationally accepted rating system: Class I: Moving water with a few riffles and small waves. Class II: Easy rapids with smaller waves, clear channels that are obvious without scouting. Class III: Rapids with high, irregular waves. Class IV: Long, difficult rapids with constricted passages that often require complex maneuvering in turbulent water.
Class V: Extremely difficult, long, and very violent rapids with highly congested routes, which should be scouted from shore. I have been a commercial river guide for 18 years and the guests that I have taken down the multiple rivers I have worked ask a variety of questions.
I have always explained how the gradient drop makes the water move faster, rocks or objects in the river direct the current, and the turbulence makes the water bubbly which makes the water appear white. Check out some of the content.
Redirected from White water. The term is also used loosely to refer to less-turbulent but still agitated flows. The term is also used as an adjective describing boating on such rivers, such as whitewater canoeing or whitewater kayaking. Four factors, separately or in combination, can create rapids: gradient, constriction, obstruction and flow rate.
Gradient, constriction and obstruction are streambed topography factors and are relatively consistent. Flow rate is dependent upon both seasonal variation in precipitation and snowmelt and upon release rates of upstream dams. Streambed topography is the primary factor in creating rapids, and is generally consistent over time.
Increased flow, as during a flood or high rainfall season can make permanent changes to the streambed by displacing rocks and boulders, by deposition of alluvium or by creating new channels for flowing water. The gradient of a river is the rate at which it loses elevation along its course. Shallow gradients produce gentle, slow rivers while steep gradients are associated with raging torrents. This pressure causes the water to flow more rapidly hence the name and to react differently to riverbed events rocks, drops, etc.
