International Scale Of River Difficulty
The international scale of river difficulty is an American system used to rate the difficulty of navigating a stretch of river, or a single (sometimes whitewater) Rapids, rapid. The scale was created by the American Whitewater, American Whitewater Association to evaluate rivers throughout the world, hence ''international'' in the title. It should not be confused with the internationally used whitewater scale, which is published and adapted by a committee of the International Canoe Federation (ICF). The grade reflects the technical difficulty and skill level required associated with the section of river. The scale is of use to various water sports and activities, such as rafting, riverboarding, whitewater canoeing, stand up paddle surfing, and whitewater kayaking. Classification There are six categories, each referred to as ''grade'' or ''class'' followed by a number. The scale is not linear, nor is it fixed. For instance, there can be difficult grade twos, easy grade threes, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paddling
Paddling with regard to watercraft is the act of manually propelling a boat using a paddle. The paddle, which consists of one or two blades joined to a shaft, is also used to steer the vessel. The paddle is not connected to the boat (unlike in rowing where the oar is connected to the boat). Canoeing Canoeing is the activity of paddling a canoe for leisure, navigation or exploration. In America the term refers exclusively to using one or more single blades or paddles to propel a canoe. In the United Kingdom and some other countries in Europe however, canoeing is also used to refer to kayaking, and canoeing is then often called ''Canadian canoeing'' to distinguish canoeing from kayaking. There are sub-varieties of canoeing, such as touring and whitewater or wildwater canoeing, and outrigger canoeing. Traveling in a whitewater raft can involve using either paddles, or a pair of oars, or both. Outrigger canoe racing is a team paddling sport which uses the outrigger canoe. Kayak ...

Hazard Scales
A hazard is a potential source of harm. Substances, events, or circumstances can constitute hazards when their nature would allow them, even just theoretically, to cause damage to health, life, property, or any other interest of value. The probability of that harm being realized in a specific ''incident'', combined with the magnitude of potential harm, make up its risk, a term often used synonymously in colloquial speech. Hazards can be classified in several ways; they can be classified as Natural hazard, natural, Anthropogenic hazard, anthropogenic, technological, or any combination, such as in the case of the natural phenomenon of wildfire becoming more common due to human-made climate change or more harmful due to changes in building practices. A common theme across many forms of hazards in the presence of Potential energy, stored energy that, when released, can cause damage. The stored energy can occur in many forms: chemical, mechanical, thermal hazards and by the populations ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canoeing And Kayaking
The following outline is provided as an overview of canoeing and kayaking: Canoeing – recreational boating activity or paddle sport in which you kneel or sit facing forward in an open or closed-decked canoe, and propel yourself with a single-bladed paddle, under your own power. Kayaking – use of a kayak for moving across water. It is distinguished from canoeing by the sitting position of the paddler and the number of blades on the paddle. A kayak is a boat where the paddler faces forward, legs in front, using a double-bladed paddle. Most kayaks have closed decks. What ''type'' of things are canoeing and kayaking? * Exercise – bodily activity that enhances or maintains physical fitness and overall health or wellness. ** Aerobic exercise – physical exercise that intends to improve the oxygen system. Aerobic means "with oxygen", and refers to the use of oxygen in the body's energy-generating process (the citric acid cycle). * Recreation – activity of leisure, l ...

Degree Of Difficulty
Degree of difficulty (DD, sometimes called tariff or grade) is a concept used in several sports and other competitions to indicate the technical difficulty of a skill, performance, or course, often as a factor in scoring. Sports which incorporate a degree of difficulty in scoring include bouldering, cross-country skiing, diving, equestrianism, figure skating, freestyle skiing, gymnastics, rhythmic gymnastics, surfing, synchronized swimming and trampoline. Degree of difficulty is typically intended to be an objective measure, in sports whose scoring may also rely on subjective judgments of performance. By sport Diving The International Swimming Federation computes the degree of difficulty of dives according to a five-part formula, incorporating height, number of somersaults and twists, positioning, approach, and entry. The total judges' score is multiplied by the dive's degree of difficulty to determine the total score. Figure skating In figure skating, each jump element is as ...

Capsize
Capsizing or keeling over occurs when a boat or ship is rolled on its side or further by wave action, instability or wind force beyond the angle of positive static stability or it is upside down in the water. The act of recovering a vessel from a capsize is called righting. Capsize may result from broaching, , loss of stability due to cargo shifting or flooding, or in high speed boats, from turning too fast. If a capsized vessel has enough flotation to prevent sinking, it may recover on its own in changing conditions or through mechanical work if it is not stable inverted. Vessels of this design are called self-righting. Small vessels In dinghy sailing, a practical distinction can be made between being knocked down (to 90 degrees; on its beam-ends, figuratively) which is called a capsize, and being inverted, which is called being turtled. Small dinghies frequently capsize in the normal course of use and can usually be recovered by the crew. Some types of dinghy are occa ...

Whitewater
Whitewater forms in a rapid context, in particular, when a river's gradient changes enough to generate so much turbulence that air is trapped within the water. This forms an unstable current that froths, making the water appear opaque and white. The term "whitewater" also has a broader meaning, applying to any river or creek that has a significant number of rapids. The term is also used as an adjective describing boating on such rivers, such as whitewater canoeing or whitewater kayaking. Fast rivers 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 Streambed topography is the primary factor in creating rapids, and is generally consistent over time. Increased f ...

Flood Stage
Flood stage is the water level or stage at which the surface of a body of water has risen to a sufficient level to cause sufficient inundation of areas that are not normally covered by water, causing an inconvenience or a threat to life and property. When a body of water rises to this level, it is considered a flood event. Flood stage does not apply to areal flooding. As areal flooding occurs, by definition, over areas not normally covered by water, the presence of any water at all constitutes a flood. Usually, moderate and major stages are not defined for areal floodplains. Definition Flood stage is the water level, as read by a stream gauge or tide gauge, for a body of water at a particular location, measured from the level at which a body of water threatens lives, property, commerce, or travel. The term "at flood stage" is commonly used to describe the point at which this occurs. "Gauge height" (also referred to as "stream stage", "stage of the ody of water, or simply "stage" ...

Canoe
A canoe is a lightweight narrow water vessel, typically pointed at both ends and open on top, propelled by one or more seated or kneeling paddlers facing the direction of travel and using a single-bladed paddle. In British English, the term ''canoe'' can also refer to a kayak, while canoes are called Canadian or open canoes to distinguish them from kayaks. Canoes were developed by cultures all over the world, including some designed for use with sails or outriggers. Until the mid-19th century, the canoe was an important means of transport for exploration and trade, and in some places is still used as such, sometimes with the addition of an outboard motor. Where the canoe played a key role in history, such as the Northern United States, Canada, and New Zealand, it remains an important theme in popular culture. Canoes are now widely used for competition and pleasure, such as racing, whitewater, touring and camping, freestyle and general recreation. Canoeing has been part ...
