Inniscarra Dam
Inniscarra Dam is a buttress dam located on the River Lee in the civil parish of Inniscarra in County Cork, Ireland. Construction of the dam started in February 1953 and resulted in the formation of the Inniscarra Reservoir. The dam is owned and operated by the ESB Group and has a generation capacity of 19 MW. It over-flooded in November 2009 and caused around 100 million euros worth of damage to the city, with University College Cork University College Cork – National University of Ireland, Cork (UCC) ( ga, Coláiste na hOllscoile Corcaigh) is a constituent university of the National University of Ireland, and located in Cork.

Kaplan-type
The Kaplan turbine is a propeller-type water turbine which has adjustable blades. It was developed in 1913 by Austrian professor Viktor Kaplan, who combined automatically adjusted propeller blades with automatically adjusted wicket gates to achieve efficiency over a wide range of flow and water level. The Kaplan turbine was an evolution of the Francis turbine. Its invention allowed efficient power production in low-head applications which was not possible with Francis turbines. The head ranges from and the output ranges from 5 to 200 MW. Runner diameters are between . Turbines rotate at a constant rate, which varies from facility to facility. That rate ranges from as low as 54.5 rpm (Albeni Falls Dam) to 450 rpm. Kaplan turbines are now widely used throughout the world in high-flow, low-head power production. Development Viktor Kaplan, living in Brünn, Austria-Hungary (now Brno, Czechia), obtained his first patent for an adjustable blade propeller turbine in 1912. But t ...

Megawatt
The watt (symbol: W) is the unit of Power (physics), power or radiant flux in the International System of Units, International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantification (science), quantify the rate of Energy transformation, energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish people, Scottish invention, inventor, mechanical engineer, and chemist who improved the Newcomen steam engine, Newcomen engine with his own Watt steam engine, steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre per second against a constant opposing force of one Newton (unit), newton, the rate at which Work (physics), work is done is one watt. : \mathrm In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potentia ...

Buttress Dam
A buttress dam or hollow dam is a dam with a solid, water-tight upstream side that is supported at intervals on the downstream side by a series of buttresses or supports. The dam wall may be straight or curved. Most buttress dams are made of reinforced concrete and are heavy, pushing the dam into the ground. Water pushes against the dam, but the buttresses are inflexible and prevent the dam from falling over. Buttress or hollow gravity dams were originally built to retain water for irrigation or mining in areas of scarce or expensive resources but cheap labour. A buttress dam is a good choice in wide valleys where solid rock is rare. As designs have become more sophisticated, the virtues and weaknesses of buttress dams have become apparent. The Romans were the first to use buttresses to increase the stability of a dam wall. Buttress dams of slab concrete construction became popular in the United States in the early 20th Century with the patented process of Norwegian-American civil ...

River Lee (Ireland)
The River Lee (Irish: ''An Laoi'') is a river in Ireland. It rises in the Shehy Mountains on the western border of County Cork and flows eastwards through Cork, where it splits in two for a short distance, creating an island on which Cork's city centre is built, then passing through Cork Harbour on the south coast, one of the largest natural harbours in the world, to empty into the Celtic Sea. The catchment area of the River Lee is 1,253 km2. The long-term average flow rate of the River Lee is 40.4 cubic metres per second (m3/s) A hydro-electric scheme was built on the river, upstream from Cork City, and this part of the river now contains the Carrigadrohid and Inniscarra reservoirs. The river is crossed by 42 bridges, 29 of which are in Cork City, and one tunnel. The river also provides an stretch of salmon fishing. Name Ptolemy's ''Geography'' (2nd century AD) described a river called Δαβρωνα (''Dabrona'') or Λαβρωνα (''Labrona''), which is sometimes c ...

Civil Parishes In Ireland
Civil parishes () are units of territory in the island of Ireland that have their origins in old Gaelic territorial divisions. They were adopted by the Anglo-Norman Lordship of Ireland and then by the Elizabethan Kingdom of Ireland, and were formalised as land divisions at the time of the Plantations of Ireland. They no longer correspond to the boundaries of Roman Catholic or Church of Ireland parishes, which are generally larger. Their use as administrative units was gradually replaced by Poor_law_union#Ireland, Poor Law Divisions in the 19th century, although they were not formally abolished. Today they are still sometimes used for legal purposes, such as to locate property in deeds of property registered between 1833 and 1946. Origins The Irish parish was based on the Gaelic territorial unit called a ''túath'' or ''Trícha cét''. Following the Norman invasion of Ireland, the Anglo-Normans, Anglo-Norman barons retained the ''tuath'', later renamed a parish or manor, as a un ...

Inniscarra Lake
Inniscarra Lake is located along the River Lee in County Cork, Ireland. It is a man-made reservoir formed in the 1950s when Inniscarra Dam was constructed by the Electricity Supply Board. Construction of the dam commenced in 1953, with its floodgates first closed in 1956 and the reservoir fully formed by late 1957. The National Rowing Center is located on its banks and the Irish National Rowing Championships and other regattas are hosted there. The Coupe de la Jeunesse, a European youth rowing event, was held on Inniscarra Lake in 1999, 2008 and 2018. The lake is located largely within the civil parish of Inniscarra, and nearby settlements include Farran (on the reservoir's south bank) and Coachford and Dripsey (to the north). Fish stocks in the reservoir include rudd, roach, carp, perch, gudgeon, eels, pike and bream.

Dams In The Republic Of Ireland
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, human consumption, 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 dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. 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. History Ancient dams Early dam building took place in Mesopotamia and the Middle East. Dams were used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydroelectric Power Stations In The Republic Of Ireland
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.
