Mauvoisin Dam
Mauvoisin Dam is a concrete variable radius arch dam across the Val de Bagnes on the Dranse de Bagnes stream, in the canton of Valais, Switzerland. Initial construction on the dam commenced in 1951 and was completed in 1957, with the reservoir filling by 1958. In 1991, the dam was raised to increase the capacity of the reservoir for winter storage. The dam's primary purpose is hydroelectric power generation. The eighth highest dam in the world, Mauvoisin stands high and long, with a structural volume of . The impounded water behind the dam forms the Lac de Mauvoisin, which has a capacity of 211.5 million m3 (171,500 acre feet) and a full surface area of . The dam and reservoir control runoff from a catchment of . Flood waters are released by a gated spillway with a capacity of . Water from the dam is fed to two hydroelectric power stations with a combined capacity of 363 megawatts (MW). Mauvoisin Dam provides a hydraulic head of to the Fionnay generating station, which can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Valais
Valais ( , ; ), more formally, the Canton of Valais or Wallis, is one of the cantons of Switzerland, 26 cantons forming the Switzerland, Swiss Confederation. It is composed of thirteen districts and its capital and largest city is Sion, Switzerland, Sion. Valais is situated in the southwestern part of the country. It borders the cantons of Canton of Vaud, Vaud and Canton of Bern, Bern to the north, the cantons of Canton of Uri, Uri and Ticino to the east, as well as Italy to the south and France to the west. It is one of the three large southern Alps, Alpine cantons, along with Ticino and Grisons. It is a bilingual canton, French and German being its two official languages. Traditionally, the canton is divided into Lower, Central, and Upper Valais, the latter region constituting the German-speaking minority. Valais is essentially coextensive with the valley of the Rhône from its headwaters to Lake Geneva, separating the Pennine Alps from the Bernese Alps, the two largest mount ...

Pelton Turbine
The Pelton wheel or Pelton Turbine is an impulse-type water turbine invented by American inventor Lester Allan Pelton in the 1870s. The Pelton wheel extracts energy from the impulse of moving water, as opposed to water's dead weight like the traditional overshot water wheel. Many earlier variations of impulse turbines existed, but they were less efficient than Pelton's design. Water leaving those wheels typically still had high speed, carrying away much of the dynamic energy brought to the wheels. Pelton's paddle geometry was designed so that when the rim ran at half the speed of the water jet, the water left the wheel with very little speed; thus his design extracted almost all of the water's impulse energywhich made for a very efficient turbine. History Figure from Lester Allan Pelton's original October 1880 patent Lester Allan Pelton was born in Vermillion, Ohio in 1829. In 1850, he traveled overland to take part in the California Gold Rush. Pelton worked by selling ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dams In Switzerland
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, drinking water, human consumption, Industrial water, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as Dike (construction), dikes) are used to manage or prevent water flow into specific land regions. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam. Ancient dams were built in Mesopotamia and the Middle East for water control. The earliest known dam is the Jawa Dam (Jorda ...

Arch Dams
An arch is a curved vertical structure spanning an open space underneath it. Arches may support the load above them, or they may perform a purely decorative role. As a decorative element, the arch dates back to the 4th millennium BC, but structural load-bearing arches became popular only after their adoption by the Ancient Romans in the 4th century BC. Arch-like structures can be horizontal, like an arch dam that withstands the horizontal hydrostatic pressure load. Arches are usually used as supports for many types of vaults, with the barrel vault in particular being a continuous arch. Extensive use of arches and vaults characterizes an arcuated construction, as opposed to the trabeated system, where, like in the architectures of ancient Greece, China, and Japan (as well as the modern steel-framed technique), posts and beams dominate. Arches had several advantages over the lintel, especially in the masonry construction: with the same amount of material it can have larger ...

Giétro Glacier
The Giétro Glacier or Giétroz Glacier () is a 4 km long valley glacier located in south-western Switzerland. The 1818 Giétro Glacier catastrophe, which led to a lake outburst flood, is one of the most famous and most disastrous historical cases in the Swiss Alps. Description The Giétro Glacier lies on the northern side of the Pennine Alps in the Swiss canton of Valais. It is located in the upper Bagnes Valley, south of Martigny and Verbier. The length of the glacier is 4.45 km (2017) and its area is 5.3 km2 (2017). The glacier is fed by the snows of Mont Blanc de Cheilon (3,870 m) and La Ruinette (3,875 m). On the upper part, the glacier is relatively flat. It descends to the north on the side of Mont Rouge du Giétro and then curves to the west between Le Pleureur and Mont Rouge. On the lower part, the glacier reaches a steepness of 40% forming a large number of crevasses. The terminus is located at about 2,750 metres. Part of the glacier is linked to the ...

Glacial Lake Outburst Flood
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. Increasing glacial melting because of climate change, alongside other environmental effects of climate change (i.e. permafrost melting) mean that regions with glaciers are likely to see increased flooding risks from GLOFs. This is especially true in the Himalayas where geologies are more active. A 2023 study found 15 million people at risk from this hazard, mostly in China, India, Nepal, Pakistan, ...

Rhône
The Rhône ( , ; Occitan language, Occitan: ''Ròse''; Franco-Provençal, Arpitan: ''Rôno'') is a major river in France and Switzerland, rising in the Alps and flowing west and south through Lake Geneva and Southeastern France before discharging into the Mediterranean Sea (Gulf of Lion). At Arles, near its mouth, the river divides into the Great Rhône () and the Little Rhône (). The resulting River delta, delta forms the Camargue region. The river's source is the Rhône Glacier, at the east edge of the Cantons of Switzerland, Swiss canton of Valais. The glacier is part of the Saint-Gotthard Massif, which gives rise to three other major rivers: the Reuss (river), Reuss, Rhine and Ticino (river), Ticino. The Rhône is, with the Po (river), Po and the Nile, one of the three Mediterranean rivers with the largest Discharge (hydrology), water discharge.

Kilowatt Hour
A kilowatt-hour ( unit symbol: kW⋅h or kW h; commonly written as kWh) is a non-SI unit of energy equal to 3.6 megajoules (MJ) in SI units, which is the energy delivered by one kilowatt of power for one hour. Kilowatt-hours are a common billing unit for electrical energy supplied by electric utilities. Metric prefixes are used for multiples and submultiples of the basic unit, the watt-hour (3.6 kJ). Definition The kilowatt-hour is a composite unit of energy equal to one kilowatt (kW) multiplied by (i.e., sustained for) one hour. The International System of Units (SI) unit of energy meanwhile is the joule (symbol J). Because a watt is by definition one joule per second, and because there are 3,600 seconds in an hour, one kWh equals 3,600 kilojoules or 3.6 MJ."Half-high dots or spaces are used to express a derived unit formed from two or more other units by multiplication.", Barry N.
