The Loop, River Dart
The Loop is a section of the River Dart, Dartmoor, also known as the Dart Loop. It is perhaps the most popular section of whitewater for kayakers and canoeists in England. This section is preceded by the Upper Dart, and followed by The Lower. Overview ''The Loop'' is named as such because of the shape of its meander, much like a loop of string. This section's length is approximately 3 miles (4.8 kilometres), but to drive by car from start to finish is only 1.3 miles (2 kilometres) because of river and road geography. This section is graded at 2, with three rapids rated at grade 3. In very high water, some of the grade 2 sections will become continuous and push towards grade 3. Whitewater rapids List of rapids Most of the rapids have been named by watersports enthusiasts, and are officially referred to in guidebooks, such as ''English White Water: The British Canoe Union Guidebook''.https://books.google.com/books?id=SGt7MpOWhikC&lpg=PP1&dq=English%20White%20Water%3A&pg ...

Rapids
Rapids are sections of a river where the river bed has a relatively steep gradient, causing an increase in water velocity and turbulence. Rapids are hydrological features between a ''run'' (a smoothly flowing part of a stream) and a ''cascade''. Rapids are characterized by the river becoming shallower with some rocks exposed above the flow surface. As flowing water splashes over and around the rocks, air bubbles become mixed in with it and portions of the surface acquire a white color, forming what is called "whitewater". Rapids occur where the bed material is highly resistant to the erosive power of the stream in comparison with the bed downstream of the rapids. Very young streams flowing across solid rock may be rapids for much of their length. Rapids cause water aeration of the stream or river, resulting in better water quality. Rapids are categorized in classes, generally running from I to VI. A Class 5 rapid may be categorized as Class 5.1-5.9. While Class I rapids are eas ...

Playspot
In kayaking, a playspot is a place where there are favorable stationary features on rivers, in particular standing waves (which may be breaking or partially breaking), 'holes' and 'stoppers', where water flows back on itself creating a retentive feature (these are often formed at the bottom of small drops or weirs), or eddy lines (the boundary between slow moving water at the rivers' edge, and faster water). Playspots exist both in natural and artificial whitewater. Playboating Playboating is sometimes performed on dynamic moving features such as haystacks (large boils) and whirlpools, or on flat water (this is often referred to as flatwheeling). Playspots are found on natural whitewater, on artificial weirs, on artificial whitewater courses, and occasionally on tidal races in the sea. Popular Playspots Natural year-round playspots Europe * The Rabioux wave on the Durance in France * Hawaii-sur-Rhône on the Rhône River, in Lyon, France North America * Lunch Counter on the ...

Buckfastleigh
Buckfastleigh is a market town and civil parish in Devon, England situated beside the Devon Expressway ( A38) at the edge of the Dartmoor National Park. It is part of Teignbridge and, for ecclesiastical purposes, lies within the Totnes Deanery. It is 18 miles (29 km) east-northeast of Plymouth, 20 miles (32 km) southwest of Exeter and has a population of 3,661. It is a centre of tourism and is home to Buckfast Abbey, the South Devon Railway, the Buckfastleigh Butterfly Farm and Otter Sanctuary, the Tomb of Squire Richard Cabell and The Valiant Soldier. With 13 letters, Buckfastleigh is one of the longest place names in England with no repeated letters, tied with Buslingthorpe, Leeds and Buslingthorpe, Lincolnshire, but exceeded by Bricklehampton in Worcestershire with 14 letters. Geography Geographically, Buckfastleigh straddles the confluence of two small streams from Dartmoor which feed into the River Dart just to the east of the town. About one mile to the north lies Buckf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holne Bridge
Holne Bridge is a Grade II* listed medieval bridge over the River Dart, Dartmoor, Devon, England. It is on the road between Ashburton and Two Bridges, about 1.5 miles or 2.5 km from Ashburton, and connects Holne Chase to Ausewell. The narrowness of both this bridge and nearby New Bridge means that the length and width of vehicles on this road are restricted. The bridge is constructed of local granite and has four arches, three of which are semicircular, the other segmental. It was rebuilt in 1413, at the same time as the building of the nearby New Bridge. The two central pillars have cutwaters on both sides; on the north side of the bridge these extend up to road level and provide triangular refuges for pedestrians. Whitewater Holne Bridge is an official BCU access and egress point for kayakers and canoeists A canoe is a lightweight narrow watercraft, water vessel, typically pointed at both ends and open on top, propelled by one or more seated or kneeling paddler ...

Squirt Boating
Squirt boating is a form of whitewater kayaking where the boat is designed to be as low in volume as possible while still allowing the paddler to float. Squirt boats are designed to use both surface and underwater currents to maneuver within the water. These maneuvers can be used to effect navigational control or to perform tricks. Overview Physically, a typical squirt boat is similar to a whitewater kayak (K1) or covered canoe (C1) but is distinct in the following ways: * The side profile of a squirt boat is very flat when compared to a whitewater kayak or C1. * The volume of a squirt boat is generally less than half of the volume of a normal kayak of the same length. This often ranges from 24–35 gallons (90–130 liters) for a squirt boat, but 50–70 gallons (190–260 liters) for a typical kayak. * Squirt boats often have foot bumps that enable the boat to maintain an ultra-low volume while still providing room for the feet. * When in the water, 70–80% of the boat will be ...

River Webburn
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle. Water generally collects in a river from precipitation through a drainage basin from surface runoff and other sources such as groundwater recharge, springs, a ...

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. The moving fluid creates a space devoid of downstream-flowing fluid on the downstream side of the object. Fluid behind the obstacle flows into the void creating a swirl of fluid on each edge of the obstacle, followed by a short reverse flow of fluid behind the obstacle flowing upstream, toward the back of the obstacle. This phenomenon is naturally observed behind large emergent rocks in swift-flowing rivers. An eddy is a movement of fluid that deviates from the general flow of the fluid. An example for an eddy is a vortex which produces such deviation. However, there are other types of eddies that are not simple vortices. For example, a Rossby wave is an eddy which is an undulation that is a deviation from mean flow, but doesn't have the local closed streamlines of a vortex. Swirl and eddies in engineering The propensity of a fluid to swirl is used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Playboating
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). Specialised canoes or kayaks (boats) known as playboats are often used, but any boat can be used for playing. The moves and tricks are often similar to those performed by snowboarders, surfers or skaters, where the athlete completes spins, flips, turns, etc. With modern playboats it is possible to get the kayak and the paddler completely airborne while performing tricks. The competitive side of playboating is known as freestyle kayaking (formerly called rodeo). Playspots Playspots are typically stationary features on rivers, in particular standing waves (which may be breaking or partially breaking), hydraulic jumps, 'holes' and ' ...

Newbridge, River Dart
Newbridge or New Bridge is a Grade II* listed medieval bridge over the River Dart, Dartmoor, Devon, England. It is on the road between Ashburton and Two Bridges, and connects Aish Tor to Holne Chase. A car park is located next to the bridge and is often frequented by families, walkers, and watersports enthusiasts, though the narrowness of both this bridge and Holne Bridge means that the size of vehicles is restricted on this road. The bridge is constructed of local granite and has three semicircular arches, one smaller than the others. It was built in 1413, at the same time as the nearby Holne Bridge was reconstructed. The two pillars have cutwaters to deflect the flow of water; these extend up to road level and provide triangular refuges for pedestrians.
