Lac Du Lauvitel
Lac du Lauvitel is a lake in the commune of Le Bourg-d'Oisans in the Isère department of France. At an elevation of 1530 m, the lake has a surface area of 0.35 km2. It is situated in the Vénéon valley. It is the largest lake of the Massif des Écrins, Écrins massif and forms one slope of the Oisans region. The lake is accessible by foot from the nearby town of la Danchère. The southern part of the lake and valley are classified as part of a "réserve naturelle intégrale" since 1995. This classification aims to preserve such areas in their natural state as if entirely unaffected by human activity. This restricted area is forbidden to visitors and is instead reserved exclusively for scientific research, having been recognised in 2012 as an essential protected area for its scientific importance according to an assessment by the International Union for Conservation of Nature. Geography The surface of the lake is approximately 25 to 35 hectares, reaching 65 m in depth. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Le Bourg-d'Oisans

Lake
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oisans
L'Oisans () is a region in the French Alps, located in the départements of l'Isère and Hautes-Alpes, and corresponding to the drainage basin of the River Romanche and its tributaries (Eau d'Olle, Lignarre, Sarenne, Vénéon and Ferrand). Between Livet-et-Gavet and Le Bourg-d'Oisans, the Romanche forms a deep gorge. Description Its geographical definition coincides almost exactly with the former cantons of Le Bourg-d'Oisans (Isère) and La Grave (Hautes Alpes). The Oisans covers parts of the massifs of Belledonne, Taillefer, Grandes Rousses, Arves and Écrins. The highest point in the region is the mountain of ''Pic Lory'', a subpeak of the Barre des Écrins which reaches a height of 4,088 metres, but the most symbolic peak is la Meije which is nicknamed the "Queen of the Oisans". The Oisans is a remarkable territory, thanks to its numerous mountain chains, valleys, rivers, streams and plains. The Oisans is a very touristic region, both for winter and summer sports. Oisan ...

International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider pu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lac Du Lauvitel Panorama
Lac is the resinous secretion of a number of species of lac insects, of which the most commonly cultivated is '' Kerria lacca''. Cultivation begins when a farmer gets a stick that contains eggs ready to hatch and ties it to the tree to be infested. Thousands of lac insects colonize the branches of the host trees and secrete the resinous pigment. The coated branches of the host trees are cut and harvested as sticklac. The harvested sticklac is crushed and sieved to remove impurities. The sieved material is then repeatedly washed to remove insect parts and other material. The resulting product is known as seedlac. The prefix ''seed'' refers to its pellet shape. Seedlac, which still contains 3–5% impurity, is processed into shellac by heat treatment or solvent extraction. The leading producer of lac is Jharkhand, followed by the Chhattisgarh, West Bengal, and Maharashtra states of India. Lac production is also found in Bangladesh, Myanmar, Thailand, Laos, Vietnam, parts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moraine
A moraine is any accumulation of unconsolidated debris (regolith and rock), sometimes referred to as glacial till, that occurs in both currently and formerly glaciated regions, and that has been previously carried along by a glacier or ice sheet. It may consist of partly rounded particles ranging in size from boulders (in which case it is often referred to as boulder clay) down to gravel and sand, in a groundmass of finely-divided clayey material sometimes called glacial flour. Lateral moraines are those formed at the side of the ice flow, and terminal moraines were formed at the foot, marking the maximum advance of the glacier. Other types of moraine include ground moraines (till-covered areas forming sheets on flat or irregular topography) and medial moraines (moraines formed where two glaciers meet). Etymology The word ''moraine'' is borrowed from French , which in turn is derived from the Savoyard Italian ("mound of earth"). ''Morena'' in this case was derived from Provenà ...

Snowmelt
In hydrology, snowmelt is surface runoff produced from melting snow. It can also be used to describe the period or season during which such runoff is produced. Water produced by snowmelt is an important part of the annual water cycle in many parts of the world, in some cases contributing high fractions of the annual runoff in a watershed. Predicting snowmelt runoff from a drainage basin may be a part of designing water control projects. Rapid snowmelt can cause flooding. If the snowmelt is then frozen, very dangerous conditions and accidents can occur, introducing the need for salt to melt the ice. Energy fluxes related to snowmelt There are several energy fluxes involved in the melting of snow. These fluxes can act in opposing directions, that is either delivering heat to or removing heat from the snowpack. Ground heat flux is the energy delivered to the snowpack from the soil below by conduction. Radiation inputs to the snowpack include net shortwave (solar radiation including ...

Meltwater
Meltwater is water released by the melting of snow or ice, including glacial ice, tabular icebergs and ice shelves over oceans. Meltwater is often found in the ablation zone of glaciers, where the rate of snow cover is reducing. Meltwater can be produced during volcanic eruptions Several types of volcanic eruptions—during which lava, tephra (ash, lapilli, volcanic bombs and volcanic blocks), and assorted gases are expelled from a volcanic vent or fissure—have been distinguished by volcanologists. These are often ..., in a similar way in which the more dangerous lahars form. When meltwater pools on the surface rather than flowing, it forms melt ponds. As the weather gets colder meltwater will often re-freeze. Meltwater can collect or melt under the ice's surface. These pools of water, known as subglacial lakes can form due to geothermal heat and friction. Water source Meltwater provides drinking water for a large proportion of the world's population, as well as pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
