81-668: The Yarlung Tsangpo , also called Yarlung Zangbo ( Tibetan : ཡར་ཀླུངས་གཙང་པོ་ , Wylie : yar kLungs gTsang po , ZYPY : Yarlung Zangbo ) and Yalu Zangbu River ( Chinese : 雅鲁藏布江 ; pinyin : Yǎlǔzàngbù Jiāng ) is located in the Tibet Autonomous Region , China . It is the longest river of Tibet and the fifth longest in China. The upper section is also called Dangque Zangbu meaning "Horse River." Originating at Angsi Glacier in western Tibet, southeast of Mount Kailash and Lake Manasarovar , it later forms

162-495: A downstream direction, red gates in an upstream direction. The events are typically conducted on Grade/Class II to Grade/Class IV water, but the placement of the gates, and precision necessary to paddle them fast and "clean" (without touching a pole and adding 2 seconds to the total time), makes the moves much harder than the water's difficulty suggests. Pro level slalom competitions have specific length (350 cm (140 in) for kayaks – new rules), width, and weight requirements for

243-444: A flipped boater to regain an upright position. There are a variety of different styles of rolling, but in whitewater paddling the styles which offer protection of the face receive special emphasis. The roll is normally used instead of a T rescue (so named because two kayaks form a T shape when used). If the roll does not end with the kayaker upright they can set up again and make additional attempts. Multiple failed rolls usually result in

324-460: A heavy metal shaft and poly-synthetic blades. Advances in technology today include carbon fiber shafts with foam and carbon fiber blades on the high end, and low flex but light plastic on the low end, sometimes with rubber grips. Paddles with blades included historically measured over 200 cm, but now usually measure between 185 and 205 cm. Also the industry has begun to offer bent shafts that are ergonomically shaped to relieve stress off of

405-498: A kayak wedged in such a way that it cannot be removed without a mechanical advantage system, such as between rocks and/or underwater), and will resurface more quickly and controllably when coming off larger drops. Creek boats usually have increased "rocker," or rise, fore and aft of the cockpit for manoeuvrability. Extreme racing is a competitive form of this aspect of whitewater kayaking, in which kayakers race down steep sections and/or generally dangerous sections of whitewater. Slalom

486-598: A kayaker and inventor in Liberty, South Carolina further perfected rotational moulding for kayaks with his company Perception Kayaks. Bill advanced the sport of whitewater kayaking beyond any of his predecessors through consistent innovations in manufacturing and design. His patented processes are still used to this day. In 1980 the manufacturer Prijon in Rosenheim introduced polyethylene to Europe which made WW boating virtually maintenance and repair free in giant contrast to

567-412: A pole on the sidewalk and swinging around it with legs outstretched to end up running in the other direction, momentum intact. In a kayak this can be achieved by putting a vertical paddle blade in the opposing current when crossing from one current to another. The hardest part of the duffek is keeping your paddle vertical right by your knee, and keeping the power face always facing exactly perpendicular with

648-502: A result, in all modern Tibetan dialects and in particular in the Standard Tibetan of Lhasa , there is a great divergence between current spelling, which still reflects the 9th-century spoken Tibetan, and current pronunciation. This divergence is the basis of an argument in favour of spelling reform , to write Tibetan as it is pronounced ; for example, writing Kagyu instead of Bka'-rgyud . The nomadic Amdo Tibetan and

729-446: A selected few. 1905, Alfred Heurich, an architectural student from Leipzig , Germany , invented the "Faltboot", a folding kayak called Folboat in the US . Heurich went on to paddle over 100,000 km (62,000 mi) on rivers and lakes. 1907, Alfred Klepper, a master seamster from Rosenheim , bought the patent, improved the rigidity with a lever system and started production. Born

810-504: Is a technical competitive form of kayaking, and one of the whitewater events to appear in the Olympic Games . Racers attempt to make their way from the top to the bottom of a designated section of river as fast as possible, while correctly negotiating gates (a series of double-poles suspended vertically over the river). There are usually 18–25 gates in a race which must be navigated in sequential order. Green gates must be negotiated in

891-430: Is all about always having your paddle in the water, however holding the paddle properly is best learned in the air. To properly hold a paddle you should try to make a box with your arms and paddle, shaped with 90 degree angles at your elbows and wrists. The blades on the paddle need to be equidistant from each hand, and the power face of the blade, or scoop, should be facing your stern. This position ensures your hands are in

972-436: Is almost the forward stroke exactly backwards, although often it is shorter and the paddler may need to time "peeks" at his destination during the stroke to ensure tracking. This is an important stroke to learn as paddlers move from flat-water to whitewater, as it is a flip prevention stroke. The low brace is a manipulation of the ready position in kayaking. With the box commented on above, the paddler rotates their elbows up so

1053-399: Is an onomatopoeia which mimics the sound that is usually created when the hull of the kayak makes contact with water at the base of the waterfall. Another type of boof is the "rock boof" which is a move that uses a glancing impact with a boulder at the top of a ledge to bounce the boater over a downstream feature, often finished with a mid-air eddy turn. Rock boofs result in sounds both at

1134-458: Is an adventure sport where a river is navigated in a decked kayak . Whitewater kayaking includes several styles. River running; where the paddler follows a river and paddles rapids as they travel. Creeking usually involving smaller, steeper, and more technical waterways. Creek boats tend to be short but high volume to allow for manoeuvrability while maintaining buoyancy. Slalom requires paddlers to navigate through "gates" (coloured poles hanging above

1215-851: Is as old as the Stone Age . The raft , the catamaran , the canoe and the kayak evolved depending on the needs and environment of the indigenous peoples in different parts of the world. The modern day kayak most likely originated about 8,000 years ago along the Siberian coast line by the Yupik and then transformed from the open canoe, via the Aleut and Inuit , into an enclosed kayak. The first boats made were hard to sink because they contained inflated seal bladders, which made them ideal for navigating whitewater. The Greek , Herodotus , 484-425 BC, wrote in his travel diaries about boats with which merchandise

1296-589: Is called uchen script while the hand-written cursive form used in everyday writing is called umê script . This writing system is used across the Himalayas and Tibet . The script is closely linked to a broad ethnic Tibetan identity, spanning across areas in India , Nepal , Bhutan and Tibet. The Tibetan script is of Brahmic origin from the Gupta script and is ancestral to scripts such as Lepcha , Marchen and

1377-666: Is designed as a simple means for inputting Dzongkha text on computers. This keyboard layout was standardized by the Dzongkha Development Commission (DDC) and the Department of Information Technology (DIT) of the Royal Government of Bhutan in 2000. It was updated in 2009 to accommodate additional characters added to the Unicode & ISO 10646 standards since the initial version. Since

1458-633: Is in the middle of the consonant and vowel, it is added as a subscript. On the other hand, when the ར /ra/ comes before the consonant and vowel, it is added as a superscript. ར /ra/ actually changes form when it is above most other consonants, thus རྐ rka. However, an exception to this is the cluster རྙ /ɲa/. Similarly, the consonants ར /ra/, and ཡ /ja/ change form when they are beneath other consonants, thus ཀྲ /ʈ ~ ʈʂa/; ཀྱ /ca/. Besides being written as subscripts and superscripts, some consonants can also be placed in prescript, postscript, or post-postscript positions. For instance,

1539-402: Is likely to include running ledges, slides, and waterfalls on relatively small and tight rivers, though some will allow for very large and big volume rivers in their definition. Kayaks used for creeking usually have higher volume (more gallons or litres of displacement) and more rounded bow and stern , as these features provide an extra margin of safety against the likelihood of pinning (getting

1620-442: Is most common. Most have the ability to be "welded" after significant damage. Earliest models were typically fiberglass and it was common to join a club to learn how to build your own. Today most composite kayaks are reserved for slalom or squirt boating. There are three main categories of differences between kayak paddles: composition, twist/feather, and shaft shape/length. Earlier paddles were often made of wood and then later with

1701-528: Is simply read as it usually is and has no effect on the pronunciation of the consonant to which it is subjoined, for example ཀ་ཝ་ཟུར་ཀྭ (IPA: /ka.wa.suː.ka/). The vowels used in the alphabet are ཨ /a/, ཨི /i/, ཨུ /u/, ཨེ /e/, and ཨོ /o/. While the vowel /a/ is included in each consonant, the other vowels are indicated by marks; thus ཀ /ka/, ཀི /ki/, ཀུ /ku/, ཀེ /ke/, ཀོ /ko/. The vowels ཨི /i/, ཨེ /e/, and ཨོ /o/ are placed above consonants as diacritics, while

1782-615: Is solely for the consonants ད /tʰa/ and ས /sa/. The head ( མགོ in Tibetan, Wylie: mgo ) letter, or superscript, position above a radical is reserved for the consonants ར /ra/, ལ /la/, and ས /sa/. The subscript position under a radical can only be occupied by the consonants ཡ /ja/, ར /ra/, ལ /la/, and ཝ /wa/. In this position they are described as བཏགས (Wylie: btags , IPA: /taʔ/), in Tibetan meaning "hung on/affixed/appended", for example བ་ཡ་བཏགས་བྱ (IPA: /pʰa.ja.taʔ.t͡ʃʰa/), except for ཝ , which

1863-564: Is the deepest, and possibly longest canyon in the world. The Yarlung Tsangpo River has three major waterfalls in its course. The largest waterfall of the river, the "Hidden Falls", was not publicized in the West until 1998, when its sighting by Westerners was briefly hailed as a "discovery." They were even portrayed as the discovery of the great falls which had been the topic of stories told to early westerners by Tibetan hunters and Buddhist monks , but which had never been found by Western explorers at

1944-410: Is the duffek. In a river current generally moves downstream, but behind rocks or on shore the water may be still or actually move upstream. When a paddler moves from one of these currents to the other they can use the duffek stroke to quickly turn their boat into the direction of the current. A good visual representation of the duffek in real life is thinking about someone running down a sidewalk, grasping

2025-422: Is the essential - and some would say most artful - form of kayaking. Whereas its derivative forms (described below under the headings of Creeking, Slalom, Playboating and Squirt boating) have evolved in response to the challenges posed by riverrunning, such as pushing the levels of difficulty and/or competing, riverrunning, of its own right, is more about combining one's paddling abilities and navigational skills with

2106-550: The Austrian , Edi Hans Pawlata reinvented the Eskimo roll . 1927, Franz von Alber, and then Klaus and Arndt von Rautenfeld, claimed to have independently developed a roll with their sea kayaks. In the early 1930s, Walter Frentz, Herbert Rittlinger and a handful of others became pioneers and advocates of WW kayaking with documentaries and books. 1933, Adolf Hitler started to dissolve kayak clubs. They did not serve his plan and

2187-898: The Latin script . Multiple Romanization and transliteration systems have been created in recent years, but do not fully represent the true phonetic sound. While the Wylie transliteration system is widely used to Romanize Standard Tibetan , others include the Library of Congress system and the IPA-based transliteration (Jacques 2012). Below is a table with Tibetan letters and different Romanization and transliteration system for each letter, listed below systems are: Wylie transliteration (W), Tibetan pinyin (TP), Dzongkha phonetic (DP), ALA-LC Romanization (A) and THL Simplified Phonetic Transcription (THL). The first version of Microsoft Windows to support

2268-709: The Meghna River near Bhairab Upazila . This old channel has been gradually dying. At present the main channel of the river is called Jamuna River , which flows southward to meet the Ganges , which in Bangladesh is called the Padma . When leaving the Tibetan Plateau , the river forms the world's largest and deepest canyon, Yarlung Tsangpo Grand Canyon . The Yarlung Tsangpo River is the highest major river in

2349-527: The Pabonka Hermitage . This occurred c.  620 , towards the beginning of the king's reign. There were 21 Sutra texts held by the King which were afterward translated. In the first half of the 7th century, the Tibetan script was used for the codification of these sacred Buddhist texts, for written civil laws, and for a Tibetan Constitution. A contemporary academic suggests that the script

2430-538: The Colorado River in the Grand Canyon, accomplished this feat with hand paddles crafted by her father. Boofing, in whitewater kayaking, refers to the raising of the kayak's bow during freefall, while descending a ledge, ducking behind a boulder, or running a waterfall . This technique is used to avoid submerging the bow of the kayak by ensuring it lands flat when it hits the base of the waterfall. The term

2511-543: The Faltboot which had started it all. 1980 Holger Machatschek, together with ESKIMO kayak company in Landsberg, Germany, developed the first 2.2 m (7.2 ft) playboat called Topolino which galvanized kayaking into many new and exciting forms of extreme sports . There are five "sub-categories" in whitewater kayaking, each typically utilizes a unique kayak design: Riverrunning (practitioners use one word)

2592-519: The Indian subcontinent state that the classical orthography should not be altered even when used for lay purposes. This became an obstacle for many modern Tibetic languages wishing to modernize or to introduce a written tradition. Amdo Tibetan was one of a few examples where Buddhist practitioners initiated a spelling reform. A spelling reform of the Ladakhi language was controversial in part because it

2673-583: The South Tibet Valley and Yarlung Tsangpo Grand Canyon before passing into the state of Arunachal Pradesh , India . Downstream from Arunachal Pradesh, the river becomes far wider and is called the Siang. After reaching Assam , the river is known as the Brahmaputra . From Assam, the river enters Bangladesh at Ramnabazar. From there until about 200 years ago it used to flow eastward and joined

2754-732: The Tibetan keyboard layout is MS Windows Vista . The layout has been available in Linux since September 2007. In Ubuntu 12.04, one can install Tibetan language support through Dash / Language Support / Install/Remove Languages, the input method can be turned on from Dash / Keyboard Layout, adding Tibetan keyboard layout. The layout applies the similar layout as in Microsoft Windows. Mac OS -X introduced Tibetan Unicode support with OS-X version 10.5 and later, now with three different keyboard layouts available: Tibetan-Wylie, Tibetan QWERTY and Tibetan-Otani. The Dzongkha keyboard layout scheme

2835-410: The Tibetan script is that the consonants can be written either as radicals or they can be written in other forms, such as subscript and superscript forming consonant clusters . To understand how this works, one can look at the radical ཀ /ka/ and see what happens when it becomes ཀྲ /kra/ or རྐ /rka/ (pronounced /ka/). In both cases, the symbol for ཀ /ka/ is used, but when the ར /ra/

2916-401: The Tibetan script it is /a/. The letter ཨ is also the base for dependent vowel marks. Although some Tibetan dialects are tonal , the language had no tone at the time of the script's invention, and there are no dedicated symbols for tone. However, since tones developed from segmental features, they can usually be correctly predicted by the archaic spelling of Tibetan words. One aspect of

2997-579: The Yarlung River, bounded by the Himalayas in the south and Kang Rinpoche and Nyenchen Tanglha Mountains in the north, has less severe climate than the adjacent northern (and higher-altitude) parts of Tibet, and is home to most of the population of the Tibetan Autonomous Region . The Yarlung Tsangpo Grand Canyon , formed by a horse-shoe bend in the river where it leaves the Tibetan Plateau and flows around Namcha Barwa ,

3078-509: The arrangement of keys essentially follows the usual order of the Dzongkha and Tibetan alphabet, the layout can be quickly learned by anyone familiar with this alphabet. Subjoined (combining) consonants are entered using the Shift key. The Dzongkha (dz) keyboard layout is included in Microsoft Windows, Android, and most distributions of Linux as part of XFree86 . Tibetan was originally one of

3159-407: The basic Tibetan alphabet to represent different sounds. In addition to the use of supplementary graphemes, the rules for constructing consonant clusters are amended, allowing any character to occupy the superscript or subscript position, negating the need for the prescript and postscript positions. Romanization and transliteration of the Tibetan script is the representation of the Tibetan script in

3240-406: The boat and paddle there are several other pieces of gear that are necessary for whitewater paddling. A buoyancy aid (BA) or personal flotation device (PFD), helmet, and spray deck (sometimes known as a sprayskirt) are considered essential while a throwbag , knife, and safety whistle are recommended as standard pieces of safety gear. Many people also wear a nose clip since flipping the boat

3321-406: The boat and the paddler submerge completely into the river's flow for several seconds and up to half a minute. ‹The template How-to is being considered for merging .›   A variety of different paddle strokes are used to guide, propel and turn the boat in various ways. Some strokes are used in combinations to perform manoeuvres such as the "S-turn". Kayaking, especially in whitewater

3402-428: The boater will pivot the boat to change its direction, and by so doing, diminish the boat's speed and momentum.) A principal design characteristic of riverrunning kayaks (as well as for their closest cousin the slalom boat) is their comparatively longer length and narrower breadth (generally minimum 285 cm in length and maximum 63 cm in breadth). The longer length at the waterline not only helps to carry speed but

3483-415: The boats, which will be made out of kevlar/fibreglass/ carbon fiber composites to be lightweight and have faster hull speed. Plastic whitewater kayaks can be used in citizen-level races. Playboating, also known as Freestyle or Rodeo, is a more gymnastic and artistic kind of kayaking. While the other varieties of kayaking generally involve going from Point A to Point B, playboaters often stay in one spot in

3564-415: The c. 620 date of development of the original Tibetan script. Three orthographic standardisations were developed. The most important, an official orthography aimed to facilitate the translation of Buddhist scriptures emerged during the early 9th century. Standard orthography has not been altered since then, while the spoken language has changed by, for example, losing complex consonant clusters . As

3645-418: The consonants ག /kʰa/, ད /tʰa/, བ /pʰa/, མ /ma/ and འ /a/ can be used in the prescript position to the left of other radicals, while the position after a radical (the postscript position), can be held by the ten consonants ག /kʰa/, ན /na/, བ /pʰa/, ད /tʰa/, མ /ma/, འ /a/, ར /ra/, ང /ŋa/, ས /sa/, and ལ /la/. The third position, the post-postscript position

3726-431: The correct location on the shaft. The forward stroke is the most intuitive paddle stroke in kayaking although proper technique is important to master. To do a forward stroke the paddler holds his paddle vertically, with one hand close to the face, and the other hand outstretched outside of the knee. The paddle enters the water near the toes of the paddler, and the paddle is pushed out with the upper hand and pulled in with

3807-466: The current you are grabbing. In other words, the scoop of the blade always needs to be facing where the current is coming from. This is tricky because as you turn your blade will turn with you unless you twist your wrists to keep it static. If done correctly paddlers can enter and exit opposing currents with one duffek that can be turned into a powerful forward stroke upon completion. Rolling is an essential skill in whitewater kayaking. This technique allows

3888-794: The extreme conditions of the river. The first attempt to run was made in 1993 by a Japanese group who lost one member on the river. In October 1998, a kayaking expedition sponsored by the National Geographic Society attempted to navigate the Yarlung Tsangpo Grand Canyon . Troubled by unanticipated high water levels, the expedition ended in tragedy with the death of expert kayaker Doug Gordon . In January–February 2002, an international group consisting of Scott Lindgren, Steve Fisher, Mike Abbott, Allan Ellard, Dustin Knapp, and Johnnie and Willie Kern, completed

3969-489: The first descent of the upper Tsangpo gorge section. In November 2020, the chairman of PowerChina announced the construction of a "super" dam on the Yarlung Zangbo which would be the world's largest hydroelectric project. Tibetan script The Tibetan script has also been used for some non-Tibetic languages in close cultural contact with Tibet, such as Thakali , Nepali and Old Turkic . The printed form

4050-535: The force exerted by the water on the upper extremity, predominantly the shoulder, or collisions with objects during 'swimming' incidents. On the other hand, acute rafting injuries more commonly stem from contact with another rafter's paddle or equipment, followed by incidents where the rafter collides with an object while 'swimming.' Chronic injuries are relatively rare in rafting, contrasting with kayaking where they account for 25% to 40% of all injuries, primarily manifesting as shoulder or wrist complaints. In addition to

4131-457: The forward sweep. In paddling momentum is the paddlers best tool for successful advancement, and so ruddering or back sweeps as a way of turning, results in decreased momentum and a higher chance of getting flipped or caught in a hole or wave. To forward sweep right the paddler will need to bring their left blade to their toes like they would in a forward stroke although this time they will drop their right hand from their face, to their biceps, making

SECTION 50

4212-425: The high brace to right themselves. By dropping their elbows and reaching the necessary blade to the surface on the side they are flipping on the paddler can use the power face to pull down on while doing a side crunch to redistribute their weight over their boat. The High Brace is exactly the same technique as the C to C roll when the paddler is closer to being upside down. In order to turn the paddler needs to master

4293-746: The impact on the sport was devastating. World War II brought the paddle sport to a total halt. 1946–48, In some regions, the Allies gradually lifted the ban on river travel in Germany. Paddle clubs were again allowed to form. 1952, Walter Frentz, published an inspiring book In den Schluchten Europas (In the Canyons of Europe) that gained popularity. The book was based on his river trips prior to World War II. Publications in those days told great stories with awesome pictures of first descents but with little information regarding river conditions. The tough times of

4374-693: The kayak/canoe and in 1860 started building six boats that closely resembled Inuit canoes/kayaks, weighing approximately 36 kg (80 lb). In 1866 he published the book A Thousand Miles in the Rob Roy Canoe . The timing was right and the book became a resounding success. With the Industrial Revolution leading to more leisure time in the middle of the 19th century, people in Europe started to enjoy floating down rivers in various contraptions taking in nature previously only available to

4455-546: The longer arcs thus created between stem and stern allow the boater to more efficiently and gracefully carve into, through and out of eddies and other currents. Creeking is perhaps best thought of as a subcategory of river running, involving very technical and difficult rapids, typically in the Grade/Class IV to VI range. While people will differ on the definition, creeking generally involves higher gradient (approaching or in excess of 100 ft per mi (19 m per km)), and

4536-423: The lower hand, keeping the paddle vertical. To incorporate more than just the arms and upper back, paddlers should twist their torsos to reach and twist back while pulling to maximize their reach and power. The blade should leave the water by the paddlers' hips, and the low hand comes up to the face, with the face hand reaching out to outside the knee on its side in order to initiate the next stroke. The back stroke

4617-430: The most of the differential forces in the river's currents. For example, instead of spinning or pivoting the boat to change its direction, a riverrunner will drive the boat in such a way as to make use of the river's surface features (e.g. waves, holes and eddylines) thus conserving the boat's speed and momentum (this is in particular contrast to slalom racing, where, in the attempt to negotiate certain kinds of slalom gates,

4698-405: The movements and environments of rivers themselves. Important to a riverrunner is the experience and expression of the river in its continuity rather than, say, a penchant for its punctuated "vertical" features (e.g. standing waves, play-holes and waterfalls). As for kayak design, a "pure" riverrunning boat can be said to have "driving ability" - a blend of qualities that enables the paddler to make

4779-402: The multilingual ʼPhags-pa script , and is also closely related to Meitei . According to Tibetan historiography, the Tibetan script was developed during the reign of King Songtsen Gampo by his minister Thonmi Sambhota , who was sent to India with 16 other students to study Buddhism along with Sanskrit and written languages. They developed the Tibetan script from the Gupta script while at

4860-477: The paddle more horizontal. They will then move their blade in a semi circle around their boat finishing at their stern. The back sweep is the forward sweep in reverse, move the blade from the stern to the bow in a semi circle. Matching forward sweeps and back sweeps together is the fastest way to turn a boat if needed. When paddling downstream paddlers can use some advanced paddle strokes along with differing currents to quickly turn their boat, one of these strokes

4941-433: The paddler running out of breath and "swimming" (a swim means exiting the boat completely and entering the water). Handpaddling refers to paddling without a conventional paddle. Instead, the kayaker uses plastic hand paddles. This technique is appropriate for paddlers that prefer to roll without a paddle (hand roll). Audrey Adamchak, age 14, thought to be the youngest woman to kayak the classic 225 miles whitewater stretch of

5022-662: The paddlers wrists. Many companies also offer specialized rubber grips to ease the paddlers grip and provide a place to feel where hands should hold the shaft. Small and regular shaft thicknesses may be available as well to offer smaller paddlers more comfort while gripping the paddle. Kayaking and Rafting are considered an extreme sport. While considered not too extreme or difficult, on occasion it can be dangerous and cause serious injuries. Kayaking and rafting exhibit distinct injury rates, with kayaking experiencing 3 to 6 injuries and rafting ranging from 0.26 to 2.1 per 100,000 boating days. In kayaking, acute injuries typically result from

5103-543: The post war era had come to an end and people traveled abroad again looking for adventures with Folboats and canoes. 1955, Herbert Baschin in Stuttgart built the first polyester /fiber kayak. Despite the much improved manoeuvrability and material, Baschin's hard shell was received with skepticism by paddle sport enthusiasts who were in love with their folboats and depended on public transportation. The ice broke when owning an automobile became affordable. The hard shell kayak

5184-424: The power face faces the sky. To brace the paddler takes "the box" and moves it out to the side they are falling over on. Keeping their elbows high they can slap the outstretched blade down on the water and push down and slide it back towards their boat as they redistribute their weight over of their boat, stopping themselves from flipping over. If the paddler is already well on their way to flipping over they may use

5265-451: The river (usually in a hole, pourover or on a wave) where they work with and against the dynamic forces of the river to perform a variety of manoeuvres. These can include surfing, spinning, and various vertical moves (cartwheels, loops, blunts, pistol and donkey flips, and many others), spinning the boat on all possible axes of rotation. More recently, aerial moves have become accessible, where paddlers perform tricks having gained air from using

5346-546: The river). Slalom was originally the only whitewater event to be in the Olympics but Kayak Cross - a new subcategory of slalom involving gates and more natural whitewater elements - featured in the 2024 Paris Olympics. Play boating involves staying on one feature of the river and is more artistic than the others. Squirt boating uses low-volume boats (usually made specifically for the paddler) to perform special moves in whitewater features. Paddling on rivers, lakes and oceans

5427-764: The scripts in the first version of the Unicode Standard in 1991, in the Unicode block U+1000–U+104F. However, in 1993, in version 1.1, it was removed (the code points it took up would later be used for the Burmese script in version 3.0). The Tibetan script was re-added in July, 1996 with the release of version 2.0. The Unicode block for Tibetan is U+0F00–U+0FFF. It includes letters, digits and various punctuation marks and special symbols used in religious texts: Whitewater kayaking Whitewater kayaking

5508-594: The speed and bounce of the wave. Kayaks used for playboating generally have relatively low volume in the bow and stern, allowing the paddler to submerge the ends of the kayak with relative ease. Competitions for playboating or freestyle are sometimes called whitewater rodeo in the US, but more frequently just referred to as freestyle events in UK and Europe. Squirt boating incorporates the use of low-volume boats to perform special moves in whitewater features. Squirt boating predates, and

5589-470: The surrounding vegetation changes from cold desert to arid steppe to deciduous scrub vegetation. It ultimately changes into conifer and rhododendron forest. The tree line is approximately at 3,200 metres (10,500 ft). Sedimentary sandstone rocks found near the Tibetan capital of Lhasa contain grains of magnetic minerals that record the Earth's alternating magnetic field current. The basin of

5670-473: The time. The Chinese authorities contradicted, however, saying that Chinese geographers, who explored the gorge from 1973 on, had already taken pictures of the falls in 1987 from a helicopter. Since the 1990s the Yarlung Tsangpo River has been the destination of a number of teams that engage in exploration and whitewater kayaking . The river has been called the "Everest of Rivers" because of

5751-462: The top of the drop (boat impacting rock) and the bottom (boat bellyflopping into the water). Whitewater kayaks differ from many other types of recreational kayaks in that they are intended specifically to be used in rapids. As a result, they have several features that make them safer and more durable in this environment. It is not recommended to use touring kayaks in whitewater rivers. Rotomolded plastic that can withstand repeated impacts and abrasion

5832-512: The vowel ཨུ /u/ is placed underneath consonants. Old Tibetan included a reversed form of the mark for /i/, the gigu 'verso', of uncertain meaning. There is no distinction between long and short vowels in written Tibetan, except in loanwords , especially transcribed from the Sanskrit .

The valley descends from 4,500 metres (14,800 ft) above sea level to 3,000 metres (9,800 ft). As it descends,

6075-430: Was brought from Armenia to Babylon . The boats were made of a wooden framework that was covered with animal skins. Mules hauled the precious skins back to Armenia. The Russian , Grigori Ivanovitch Langsdorff , reported from his trip around the world (1803–07) on the ease and elegance of paddling Eskimo (Inuit) kayaks/canoes. The Scot , John MacGregor , came back from his North American trip full of excitement about

6156-415: Was critical to the foundation of, playboating. Squirt boats are often fairly long and flat, with low volume throughout the design. Because squirt boats are custom built to the paddlers weight, inseam, and personal preference, they are constructed with composite materials instead of plastic. Many squirt moves are intended to submerge all or part of the craft and paddler, such as the "mystery move," in which both

6237-531: Was easily hauled to rivers and remote put-ins that were not accessible before. In the late 60s the WW sport started to spread from Europe around the world and transformed from adventure trips into a hardcore sport. With it came safety consciousness and protective gear. 1973, Tom Johnson, a racer and trainer from Kernville, California designs and markets the Hollowform: the first roto-moulded polyethylene boat.

The incomplete Dunhuang manuscripts are their key evidence for their hypothesis, while the few discovered and recorded Old Tibetan Annals manuscripts date from 650 and therefore post-date

6480-473: Was mass-produced by a garbage can manufacturing company. These virtually indestructible boats revolutionized the sport and quickly took off in California . Paddlers no longer had to constantly repair their boats during and after trips. They began to be able to use rocks as part of the strategy of negotiating difficult rapids. Hard runs became more accessible to less-skilled paddlers. In 1978, Bill Masters ,

6561-523: Was the Western culture 's invention of a paddle craft that for the first time in human history that allowed hardy enthusiasts to see wild river sections and canyons never before seen by the human eye. The design not only made it suitable for whitewater (WW); it was also easy to travel with and was affordable. World War I stopped any progress. 1920s, boating on WW with Folboats developed. Boaters flocked to rivers and lakes by train or bus. During that time,
