19-624: The Duilong is the largest tributary of the Lhasa River, with a length of 137 kilometres (85 mi) and a basin area of 4,988 square kilometres (1,926 sq mi). The valley of the Duilong River leads south to the Lhasa River, and is contained by two ridges of the Nianqing Tanggula Mountains . The Duilong has hydro-electrical power generation capacity of 4,000  KW. The non-monsoon season lasts from October to May each year, and

38-521: A 2,213 m topographic prominence and is 166 kilometres (103 mi) away from a higher point. Large areas of the eastern sector are snow-covered. Two-thirds of the glaciers, accounting for five-sixths of the area, lie in the eastern section. This section receives the southwest monsoons, which enter the Tibetan plateau at the Yarlung Zanbo river's Grand Bend. The air is forced up by the terrain, and yields

57-648: A 700-kilometre (430 mi) long mountain range , and subrange of the Transhimalaya System, located in Tibet and the Tibet Autonomous Region of China . One source says the Nyenchen Tanglha Mountains range is about 1,000 km (620 mi) in length. Its highest point is 7,090 m (23,260 ft) located 100 km (62 mi) to the northwest of Lhasa . The range is parallel to

76-730: A longitude between 90°E and 97°E. Together with the Gangdise Shan located further west, it forms the Transhimalaya which runs parallel to the Himalayas north of the Yarlung Tsangpo River . The Drukla Chu river rises in the Nyenchen Tanglha Mountains, where it is called the Song Chu river, and joins the Gyamda Chu river. The combined rivers run about 100 kilometres (62 mi) southeast to

According to the Langzhou Glaciers Research Institute, there are a total of 2,905 glaciers in the range covering a total area of 5,898 square kilometres (2,277 sq mi). Most of the peaks in East Nyenchen Tanglha, called the " Alps of Tibet", are unclimbed. Sepu Kangri itself

114-570: The Himalayas in the Transhimalayas , and north of the Yarlung Tsangpo River. Another source says the Nyenchen Tanglha Mountains extend 460 miles (740 km) from Nyêmo County in the west to Ranwu County (the southwestern part of Baxoi County ) in the east. Its highest peak is Mount Nyenchen Tanglha ( Nyainqêntanglha Feng ) at 7,162 metres (23,497 ft). The southern side of

133-570: The Lhasa River , the largest tributary of the Yarlung Tsangpo. West Nyenchen Tanglha includes the four highest peaks in the range, all above 7,000 metres (23,000 ft): Mount Nyenchen Tanglha (7162m), Nyenchen Tanglha II (7117m), Nyenchen Tanglha III (7046m) and Jomo Gangtse (7048m), all located in Damxung County of Lhasa. West Nyenchen Tanglha separates the basins of the Yarlung Tsangpo in

152-689: The Matterhorn of the East Nyenchen Tanglha. Gangdise Shan The Kailash Range , Kailas Range , Gangdisi Mountains , Gangdese Range or Gangdisê Range , is a mountain range on the Tibetan Plateau of Tibet Autonomous Region of China . Kailash Range is the western subrange of the Transhimalaya system, while Nyenchen Tanglha is the eastern subrange of Transhimalaya. Kailash range has Koyul Ridge to its south, Pangong Range (a subrange of Karakoram Range ) to its west, Skakjung pasture & Dumchele border trade village to its south near

171-460: The disputed India-China " Line of Actual Control " (LAC). Kailash Range's tallest peak, Lunpo Gangri (7,095 meters or 23,278 feet), is not very famous. The second highest peak, Mount Kailash (6,638 meters or 21,778 feet), is well-known across the world as it is the most sacred mountain in four religions: Hinduism , Buddhism , Jainism . and Bon (which shares many similarities and influences with Tibetan Buddhism) Indus River system

190-420: The Nyenchen Tanglha Mountains is precipitous, and falls by around 2,000 metres (6,600 ft), while the northern side is fairly level and descends about 1,000 metres (3,300 ft). Most of the mountains are below 6,500 metres (21,300 ft). They contain 7080 glaciers covering an area of 10,700 square kilometres (4,100 sq mi). The Nyenchen Tanglha Mountains have an average latitude of 30°30'N and

209-518: The Yarlung Tsangpo river. The range is divided into two main parts: the West and East Nyenchen Tanglha, with a division at the 5,432 metres (17,822 ft) high Tro La Pass near Lhari Town . The West Nyenchen Tanglha lies to the southeast of Namtso . The range trends to the northeast, and forms part of the northern watershed of the Yarlung Tsangpo River. The northeastern section is drained by

228-579: The conflicting demands for irrigation and hydroelectric power generation. It could not be built in the lower reaches, where the river is paralleled by the Qinghai-Xizang Road, or in the middle reach where it would cover the Yangbajain geothermal field. The chosen location was therefore upstream, controlling a catchment area of 1,580 square kilometres (610 sq mi) with an annual normal runoff of 394,000,000 cubic metres (1.39 × 10 cu ft). If

247-483: The highest rainfall and moistest air of the plateau, which feeds the development of glaciers. There are thirty-two glaciers that are over 10 kilometres (6.2 mi) long. Kyagquen Glacier is the largest, covering 207 square kilometres (80 sq mi) and extending for 35.3 kilometres (21.9 mi). The end of the Qiaqing glacial tongue is at 2,530 metres (8,300 ft) in an area of mountain forests. The glacier foot

266-513: The levels of arsenic in the river, at 205.6 μg/L were higher than the WHO guideline of 10 μg/L for drinking water. The source of the pollution seems to be untreated water from the Yangbajain Geothermal Field power station. It can be detected 90 kilometres (56 mi) downstream from this site. A 1995 paper concluded that proposed Yangjinshi Reservoir would provide a good balance between

285-595: The monsoon season from June to October. 80% of the precipitation is in the monsoon season, when warm and moist air is transported to the Tibet Plateau from the south Indian Ocean. The Qinghai–Tibet Railway approaches Lhasa from the northwest. It descends from the Amdo grasslands to Nagchu and Damshung , and then follows the Toelung River from Yangpachen through Toelung Dechen county into west Lhasa. A new railway bridge

304-654: The south from the endorheic basins of the Changtang in the north. East Nyenchen Tanglha, located in Nagqu , Chamdo and Nyingchi , marks the water divide between the Yarlung Tsangpo to the south and the Nak Chu river (which becomes the Nujiang and Salween in its lower reach) to the north. The rugged and heavily glaciated range counts more than 240 peaks over 6,000 metres (20,000 ft), culminating with Sepu Kangri (6,956 m) which has

323-610: The water level were maintained at 4,360 metres (14,300 ft) above sea level, the reservoir would have a capacity of 81,000,000 cubic metres (2.9 × 10 cu ft) including available storage of 19,000,000 cubic metres (670,000,000 cu ft). The project would include a 4500 kW power station.

342-438: Was attempted twice by Chris Bonington and Charles Clarke in 1997 and 1998, about which experience Bonington and Clarke wrote the book Tibet's Secret Mountain: The Triumph of Sepu Kangri ( ISBN   0756762308 ). The summit was finally reached on 2 October 2002 by Mark Newcomb and Carlos Buhler . In 2005 Mick Fowler and Chris Watts climbed Kajaqiao, and in 2007 Fowler returned with Paul Ramsden to climb Manamcho, known as

361-598: Was built over the Lhasa river to link the station in Liuwu township on the south side of the river to central Lhasa on the north side. The southern Tibetan Plateau is tectonically active, and contains many geothermal springs. Although rivers in Tibet are generally considered to be clean, the water of the Duilong is affected by these springs. A 2015 study reported that during the non-monsoon season
