List Of Hydroelectric Power Station Failures
This is a list of major hydroelectric power station failures due to damage to a hydroelectric power station or its connections. Every generating station trips from time to time due to minor defects and can usually be restarted when the defect has been remedied. Various protections are built into the stations to cause shutdown before major damage is caused. Some hydroelectric power station failures may go beyond the immediate loss of generation capacity, including destruction of the turbine itself, reservoir breach and significant destruction of national grid infrastructure downstream. These can take years to remedy in some cases. Where a generating station is large compared to the connected grid capacity, any failure can cause extensive disruption within the network. A serious failure in a proportionally large hydroelectric generating station or its associated transmission line will remove a large block of power from the grid that may lead to widespread disturbances.

Mangla Dam
The Mangla Dam () is a multipurpose dam situated on the Jhelum River, lying in the Mirpur District of Pakistan administered Azad Kashmir and the Jhelum District in Punjab, Pakistan, Punjab, Pakistan. It is the List of largest dams, sixth-largest dam in the world. The fort of Mangla, which sits at the mouth of the dam, serves as its namesake. In November 1961, the project's selected contractors were revealed; it was announced that Binnie & Partners, a United Kingdom, British engineering firm, was going to serve as the lead designers, engineers, and inspectors for the construction of the dam (led by Geoffrey Binnie).

Province Of Pordenone
The province of Pordenone (; ; ) was a province in the autonomous region of Friuli-Venezia Giulia, Italy, subdivided from the province of Udine in 1968. Its capital was the city of Pordenone. The province was abolished on 30 September 2017; it was reestablished in 2019 as the regional decentralization entity of Pordenone (; ), and was reactivated on 1 July 2020.

Vajont Dam
The Vajont Dam or Vaiont Dam is a disused hydro-electric dam in northern Italy. It is one of the tallest dams in the world, with a height of . It is in the valley of the Vajont (river) under Monte Toc, in the municipality of Erto e Casso, north of Venice. The dam was conceived in the 1920s and eventually built between 1957 and 1960 by Società Adriatica di Elettricità, at the time the electricity supply and distribution monopoly in northeastern Italy. The engineer was Carlo Semenza (1893–1961). In 1962, the dam was nationalized and came under the control of ENEL as part of the Italian Ministry of Public Works. On 9 October 1963, during initial filling of the lake, a landslide caused a megatsunami in which of water overtopped the dam in a wave of , bringing massive flooding and destruction to the Piave Valley below, destroying several villages and towns, causing an estimated 1,900 to 2,500 deaths. The dam itself remained almost intact and two-thirds of the water ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Malpasset Dam
The Malpasset Dam was an arch dam (convex surface facing upstream) on the Reyran, Reyran River, north of Fréjus on the French Riviera. It collapsed on 2 December 1959, killing 423 people in the resulting flood. The breach was caused by a tectonic fault in the impermeable rock base, which had been inadequately surveyed. Nearby road-building works, using explosives, may also have contributed to the disaster. Construction The structure was a doubly curved, equal-angle, arch-type dam with variable radius. It was built to supply drinking and irrigation water for the region. Construction began in April 1952 and was finished in 1954. Another source reported that construction began as early as 1941. Delays due to lack of funding and labor strikes interrupted construction a few times. The project was led by well-known French engineer Andre Coyne, André Coyne. Construction cost 580 million francs (by 1955 prices), and was funded and owned by Var (département), Var Département in France, ...

Niagara River
The Niagara River ( ) flows north from Lake Erie to Lake Ontario, forming part of the border between Ontario, Canada, to the west, and New York, United States, to the east. The origin of the river's name is debated. Iroquoian scholar Bruce Trigger suggests it is derived from a branch of the local Neutral Confederacy, referred to as the ''Niagagarega'' people on several late- 17th-century French maps. George R. Stewart posits that it comes from an Iroquois town named ''Ongniaahra'', meaning "point of land cut in two." The river, occasionally described as a strait, is approximately long and includes Niagara Falls. Over the past 12,000 years, the falls have moved roughly upstream from the leading edge of the Niagara Escarpment, creating a gorge below the falls. Today, the diversion of the river for electricity generation has significantly slowed the rate of erosion. The total elevation drop along the river is . The Niagara Gorge, downstream from the falls, includes the N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Niagara Gorge
Niagara Gorge is an long canyon carved by the Niagara River along the Canada–United States border, between the U.S. state of New York (state), New York and the Provinces and territories of Canada, Canadian province of Ontario. It begins at the base of Niagara Falls and ends downriver at the edge of the geological formation known as the Niagara Escarpment near Queenston, Queenston, Ontario, where the falls originated about 12,500 years ago. The position of the falls has Scarp retreat, receded upstream toward Lake Erie because of the falling waters' slow erosion of the riverbed's hard Lockport dolomite (rock), dolomite (a form of limestone that is the surface rock of the escarpment), combined with rapid erosion of the relatively soft layers beneath it. This erosion has created the gorge. The force of the river current in the gorge is one of the most powerful in the world; because of the dangers this presents, kayaking the gorge has generally been prohibited. On multiple occasions ...

Niagara Falls, New York
Niagara Falls is a City (New York), city in Niagara County, New York, United States. As of the 2020 United States census, 2020 census, the city had a total population of 48,671. It is adjacent to the Niagara River, across from the city of Niagara Falls, Ontario, and named after the famed Niagara Falls which they share. The city is within the Buffalo–Niagara Falls metropolitan area and the Western New York region. While the city was formerly inhabited by Native Americans, Europeans who migrated to the Niagara Falls in the mid-17th century began to open businesses and develop infrastructure. Later in the 18th and 19th centuries, scientists and businessmen began harnessing the power of the Niagara River for electricity and the city began to attract manufacturers and other businesses drawn by the promise of inexpensive hydroelectric power. After the 1960s, however, the city and region experienced an economic decline. As industries left the region, affluent and middle-class families ...
