Whitewater, the Glossary
Whitewater forms in the context of rapids, in particular, when a river's gradient changes enough to generate so much turbulence that air is trapped within the water.[1]

Alluvium
Alluvium is loose clay, silt, sand, or gravel that has been deposited by running water in a stream bed, on a floodplain, in an alluvial fan or beach, or in similar settings.
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 paddles.
Canoe freestyle
Canoe freestyle (also known as playboating) is a discipline of whitewater kayaking or canoeing where people perform various technical moves in one place (a playspot), as opposed to downriver whitewater canoeing or kayaking where the objective is to travel the length of a section of river (although whitewater paddlers will often stop and play en route). Whitewater and canoe freestyle are whitewater sports.
See Whitewater and Canoe freestyle
Canoe slalom
Canoe slalom (previously known as whitewater slalom) is a competitive sport with the aim to navigate a decked canoe or kayak through a course of hanging downstream or upstream gates on river rapids in the fastest time possible.
See Whitewater and Canoe slalom
Catamaran
A catamaran (informally, a "cat") is a watercraft with two parallel hulls of equal size.
Central Finland
Central Finland (Keski-Suomi; Mellersta Finland) is a region (maakunta / landskap) in Finland.
See Whitewater and Central Finland
Colander
A colander (or cullender) is a kitchen utensil used to strain foods such as pasta or to rinse vegetables.
Eddy (fluid dynamics)
In fluid dynamics, an eddy is the swirling of a fluid and the reverse current created when the fluid is in a turbulent flow regime.
See Whitewater and Eddy (fluid dynamics)
Elevation
The elevation of a geographic ''location'' is its height above or below a fixed reference point, most commonly a reference geoid, a mathematical model of the Earth's sea level as an equipotential gravitational surface (see Geodetic datum § Vertical datum).
Fluid dynamics
In physics, physical chemistry and engineering, fluid dynamics is a subdiscipline of fluid mechanics that describes the flow of fluids—liquids and gases.
See Whitewater and Fluid dynamics
Foam
Foams are materials formed by trapping pockets of gas in a liquid or solid.
French Alps
The French Alps (Alpes françaises) are the portions of the Alps mountain range that stand within France, located in the Auvergne-Rhône-Alpes and Provence-Alpes-Côte d'Azur regions.
See Whitewater and French Alps
Granite
Granite is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase.
Igneous rock
Igneous rock, or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic.
See Whitewater and Igneous rock
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) rapid. Whitewater and international scale of river difficulty are whitewater sports.
See Whitewater and International scale of river difficulty
Kayak
A kayak is a small, narrow human-powered watercraft typically propelled by means of a long, double-bladed paddle.
Kayak roll
A kayak roll or Eskimo roll is the act of righting a capsized kayak by use of body motion and/or a paddle.
Limestone
Limestone (calcium carbonate) is a type of carbonate sedimentary rock which is the main source of the material lime.
List of whitewater rivers
A whitewater river is any river where its gradient and/or flow create rapids or whitewater turbulence.
See Whitewater and List of whitewater rivers
McKenzie River dory
The McKenzie River dory, or drift boat, is an adaptation of the open-water dory converted for use in rivers.
See Whitewater and McKenzie River dory
Murchison Falls
Murchison Falls, also known as Kabalega Falls, is a waterfall at the apex of Lake Albert on the Victoria Nile in Uganda.
See Whitewater and Murchison Falls
Packraft
Packraft and trail boat are colloquial terms for a small, portable inflatable boat designed for use in all bodies of water, including technical whitewater and ocean bays and fjords.
Personal flotation device
A personal flotation device (PFD; also referred to as a life jacket, life preserver, life belt, Mae West, life vest, life saver, cork jacket, buoyancy aid or flotation suit) is a flotation device in the form of a vest or suit that is worn by a user to prevent the wearer from drowning in a body of water.
See Whitewater and Personal flotation device
Portage
Portage or portaging (CA) is the practice of carrying water craft or cargo over land, either around an obstacle in a river, or between two bodies of water.
Raft
A raft is any flat structure for support or transportation over water.
Rafting
Rafting and whitewater rafting are recreational outdoor activities which use an inflatable raft to navigate a river or other body of water. Whitewater and rafting are whitewater sports.
Rapids
Rapids are sections of a river where the river bed has a relatively steep gradient, causing an increase in water velocity and turbulence. Whitewater and Rapids are rivers.
River
A river is a natural flowing freshwater stream, flowing on land or inside caves towards another body of water at a lower elevation, such as an ocean, lake, or another river. Whitewater and river are rivers.
River bugging
River bugging is a whitewater sport where a single person navigates a stretch of river in a craft known as a river bug. Whitewater and river bugging are whitewater sports.
See Whitewater and River bugging
River surfing
River surfing is the sport of surfing either standing waves, tidal bores or upstream waves in rivers. Whitewater and river surfing are rivers and whitewater sports.
See Whitewater and River surfing
Sieve
A sieve, fine mesh strainer, or sift, is a tool used for separating wanted elements from unwanted material or for controlling the particle size distribution of a sample, using a screen such as a woven mesh or net or perforated sheet material.
Spray deck
A spraydeck (sprayskirt in N. America, akuilisaq or tuiitsoq in Greenland) is a flexible waterproof cover for a boat (in particular for a kayak or a canoe) with holes for the passengers' waists.
Standing wave
In physics, a standing wave, also known as a stationary wave, is a wave that oscillates in time but whose peak amplitude profile does not move in space.
See Whitewater and Standing wave
Stream gradient
Stream gradient (or stream slope) is the grade (or slope) of a stream. Whitewater and stream gradient are rivers.
See Whitewater and Stream gradient
Turbulence
In fluid dynamics, turbulence or turbulent flow is fluid motion characterized by chaotic changes in pressure and flow velocity.
Wave
In physics, mathematics, engineering, and related fields, a wave is a propagating dynamic disturbance (change from equilibrium) of one or more quantities.
Weir
A weir or low-head dam is a barrier across the width of a river that alters the flow characteristics of water and usually results in a change in the height of the river level. Whitewater and weir are rivers.
Whitewater canoeing
Whitewater canoeing is the sport of paddling a canoe on a moving body of water, typically a whitewater river. Whitewater and whitewater canoeing are whitewater sports.
See Whitewater and Whitewater canoeing
Whitewater kayaking
Whitewater kayaking is an adventure sport where a river is navigated in a decked kayak. Whitewater and Whitewater kayaking are whitewater sports.
See Whitewater and Whitewater kayaking
Wildwater canoeing
Wildwater canoeing is a competitive discipline of canoeing in which kayaks or canoes are used to negotiate a stretch of river speedily. Whitewater and Wildwater canoeing are whitewater sports.
See Whitewater and Wildwater canoeing
Youghiogheny River
The Youghiogheny River, or the Yough for short, is a U.S. Geological Survey.
