The lake threatens to burst through its unstable dam, which would threaten the lives and livestock of over 6000 villagers living around the Tamakoshi River.In 2012, the UNDP reported that an early warning system installed by the authorities in the late 1990s, which became defunct through lack of maintenance, will be replaced by a more modern warning system for glacial floods from the lake.
Nepal measures about 880 kilometers (547 mi) along its Himalayan axis by 150 to 250 kilometers across. It has an area of 147,516 km2 (56,956 sq mi).
The Himalayas, or Himalaya, are a mountain range in Asia separating the plains of the Indian subcontinent from the Tibetan Plateau. The range has some of the planet's highest peaks, including the highest, Mount Everest. Over 100 peaks exceeding 7,200 m (23,600 ft) in elevation lie in the Himalayas. By contrast, the highest peak outside Asia is 6,961 m (22,838 ft) tall.
The Kingdom of Bhutan is a sovereign nation, located towards the eastern extreme of the Himalayas mountain range. It is fairly evenly sandwiched between the sovereign territory of two nations: first, the People's Republic of China on the north and northwest. There are approximately 477 kilometres of border with that nation's Tibet Autonomous Region. The second nation is the Republic of India on the south, southwest, and east; there are approximately 659 kilometres with the states of Arunachal Pradesh, Assam, West Bengal, and Sikkim, in clockwise order from the kingdom. Bhutan's total borders amount to 1,139 kilometres. The Republic of Nepal to the west, the India to the south, and the Union of Myanmar to the southeast are other close neighbours; the former two are separated by only very small stretches of Indian territory.
A moraine-dammed lake occurs when the terminal moraine has prevented some meltwater from leaving the valley. Its most common shape is that of a long ribbon. Example of moraine dammed lakes include:
Rolwāling Valley , knows as a (Gaurishankar) rural municipality, is a section of the Himalayas in east-central Nepal along the Tibet border. Rolwaling Himal includes Melungtse 7181m and Melungtse II 7023m inside Tibet and Gaurishankar 7134m on the Nepal border with some 50 additional peaks over 6000m, all extending from the Nangpa La pass where the Mahalangur section begins, southwest to the Tamakosi River. The Labuche Himal section rises beyond the Tamakosi to the northwest. Rolwaling Himal is bounded on the south by the Rolwaling Valley which contain several small sherpa villages Tasi Nam, Simigau and Beding under rolwaling valley, Tasi Nam is the largest town of the area. Five to six days are required to reach Namche Bazaar after Tasilapcha pass. Visitors can trek to Everest base camp by crossing Tasilapcha or fly from Kathmandu to Lukla.
Saiful Muluk is a mountainous lake located at the northern end of the Kaghan Valley, near the town of Naran in the Saiful Muluk National Park. At an elevation of 3,224 m above sea level, the lake is located above the tree line, and is one of the highest lakes in Pakistan.
The Gandaki River, also known as the Narayani and the Gandak, is one of the major rivers in Nepal and a left bank tributary of the Ganges in India. Its total catchment area amounts to 46,300 km2 (17,900 sq mi), most of it in Nepal. In the Nepal Himalayas, it is notable for its deep canyon. The basin also contains three mountains over 8,000 m (26,000 ft), namely Dhaulagiri, Manaslu and Annapurna I. Dhaulagiri is the highest point of the Gandaki basin.
The Kosi or Koshi is a trans-boundary river which flows through Tibet, Nepal and India. It drains the northern slopes of the Himalayas in Tibet and the southern slopes in Nepal. From a major confluence of tributaries north of the Chatra Gorge onwards, the Kosi River is also known as Saptakoshi for its seven upper tributaries. These include the Tamor River originating from the Kanchenjunga area in the east and Arun River and Sun Kosi from Tibet. The Sun Koshi's tributaries from east to west are Dudh Koshi, Bhote Koshi, Tamakoshi River, Likhu Khola and Indravati. The Saptakoshi crosses into northern Bihar, India where it branches into distributaries before joining the Ganges near Kursela in Katihar district.
A glacial lake outburst flood (GLOF) is a type of outburst flood caused by the failure of a dam containing a glacial lake. An event similar to a GLOF, where a body of water contained by a glacier melts or overflows the glacier, is called a jökulhlaup. The dam can consist of glacier ice or a terminal moraine. Failure can happen due to erosion, a buildup of water pressure, an avalanche of rock or heavy snow, an earthquake or cryoseism, volcanic eruptions under the ice, or massive displacement of water in a glacial lake when a large portion of an adjacent glacier collapses into it.
Bhote Koshi in Nepal and Poiqu in Tibet, both names roughly mean "Tibetan river," is the name given to the upper course of the Sun Kosi river. It is part of the Koshi River system in Nepal.
Phewa Lake, Phewa Tal or Fewa Lake is a freshwater lake in Nepal formerly called Baidam Tal located in the south of the Pokhara Valley that includes Pokhara city; parts of Sarangkot and Kaskikot. The lake is stream-fed but a dam regulates the water reserves, therefore, the lake is classified as semi-natural freshwater lake. It is the second largest lake in Nepal; the largest in Gandaki Province after the Rara lake in the comparison to Nepal's water bodies. It is the most popular and most visited lake of Nepal. Phewa lake is located at an altitude of 742 m (2,434 ft) and covers an area of about 4.43 km2 (1.7 sq mi). It has an average depth of about 8.6 m (28 ft) and a maximum depth of 24 m (79 ft). Maximum water capacity of the lake is approximately 43,000,000 cubic metres (35,000 acre⋅ft). The Annapurna range on the north is only about 28 km away from the lake. The lake is also famous for the reflection of mount Machhapuchhre and other mountain peaks of the Annapurna and Dhaulagiri ranges on its surface. The Tal Barahi Temple is situated on an island in the lake. It is located 4 km from the city's centre Chipledhunga.
A supraglacial lake is any pond of liquid water on the top of a glacier. Although these pools are ephemeral, they may reach kilometers in diameter and be several meters deep. They may last for months or even decades at a time, but can empty in the course of hours.
Bhimeshwar,, is a municipality in north-eastern Nepal and the headquarters of Dolakha District in Bagmati Province that was established in 1997 by merging the former Village development committees Charikot, Dolakha Town, Makaibari and Mati. At the time of the 2011 Nepal census it had a population of 32,486 people living in 8,639 individual households. The town is located at an altitude of 1554 metres (5101 feet). The name of the district Dolakha came from Dolakha Town situated north-east of the headquarters Charikot Bazaar.
The Sunkoshi, also called Sunkosi, is a trans-boundary river that originates in Tibet Autonomous Region and is part of the Koshi or Saptkoshi River system in Nepal.
West Rapti drains Rapti Zone in Mid-Western Region, Nepal, then Awadh and Purvanchal regions of Uttar Pradesh state, India before joining the Ghaghara—a major left bank tributary of the Ganges known as the Karnali inside Nepal.
Imja Tsho is a glacial lake created after melt water began collecting at the foot of the Imja Glacier on the lower part of the glacier in the 1950s. A 2009 study described this lake of melt water as one of the fastest-growing in the Himalaya. Held in place by a terminal moraine, Imja Tsho threatens downstream communities with the potential for a glacial outburst flood.
The glaciers of Bhutan, which covers about 3 percent of the total surface area, are responsible for feeding all rivers of Bhutan except the Amochu and Nyere Amachu.
The lakes of Bhutan comprise its glacial lakes and its natural mountain lakes. Bhutanese territory contains some 2,674 high altitude glacial lakes and subsidiary lakes, out of which 25 pose a risk of GLOFs. There are also more than 59 natural non-glacial lakes in Bhutan, covering about 4,250 hectares (16.4 sq mi). Most are located above an altitude of 3,500 metres (11,500 ft), and most have no permanent human settlements nearby, though many are used for grazing yaks and may have scattered temporary settlements.
Climate change in Nepal is a major problem for Nepal as it is one of the most vulnerable countries to the effects of climate change. Globally, Nepal is ranked fourth, in terms of vulnerability to climate change. Floods spread across the foothills of the Himalayas and bring landslides, leaving tens of thousands of houses and vast areas of farmland and roads destroyed. In the 2020 edition of Germanwatch's Climate Risk Index, it was judged to be the ninth hardest-hit nation by climate calamities during the period 1999 to 2018. Nepal is a least developed country, with 28.6 percent of the population living in multidimensional poverty. Analysis of trends from 1971 to 2014 by the Department of Hydrology and Meteorology (DHM) shows that the average annual maximum temperature has been increasing by 0.056 °C per year. Precipitation extremes are found to be increasing. A national-level survey on the perception-based survey on climate change reported that locals accurately perceived the shifts in temperature but their perceptions of precipitation change did not converge with the instrumental records. Data reveals that more than 80 percent of property loss due to disasters is attributable to climate hazards, particularly water-related events such as floods, landslides and glacial lake outburst floods (GLOFs).
