Gordon River (Nunavut)
The Gordon River is a major perennial river located in the central highlands, south-west, and western regions of Tasmania, Australia. Course and features The Gordon River rises below Mount Hobhouse in the Franklin-Gordon Wild Rivers National Park draining the eastern slopes of the King William Range. The river flows generally south and to the west of the Gordon Range before flowing west through the Gordon Gap and spilling into Lake Gordon, an impounded reservoir created by damming the Gordon at the Gordon Dam. Together with water fed from Lake Pedder, the principal purpose of the reservoir is for generation of hydro-electricity at the Gordon Power Station. Flowing from east to west through Lake Gordon, the river continues west, passing through the Gordon Splits, a series of gorges once considered impassable until 1958 when Olegas Truchanas, a conservationist and nature photographer, was the first person to navigate the Gordon River in a kayak.

Mouth (river)
A river mouth is where a river flows into a larger body of water, such as another river, a lake/reservoir, a bay/ gulf, a sea, or an ocean. At the river mouth, sediments are often deposited due to the slowing of the current reducing the carrying capacity of the water. The water from a river can enter the receiving body in a variety of different ways. The motion of a river is influenced by the relative density of the river compared to the receiving water, the rotation of the earth, and any ambient motion in the receiving water, such as tides or seiches. If the river water has a higher density than the surface of the receiving water, the river water will plunge below the surface. The river water will then either form an underflow or an interflow within the lake. However, if the river water is lighter than the receiving water, as is typically the case when fresh river water flows into the sea, the river water will float along the surface of the receiving water as an overflow.

Denison River (Tasmania)
Denison River is a river in South West Tasmania, Australia. It is within the South West Wilderness, and drains into the Gordon River below the Gordon Splits. Its catchment starts in the south of the King William Range. It lies to the east of the Prince of Wales Range (Tasmania), north west of Gordon Dam and Lake Gordon, and west of The Spires (Tasmania). The river was travelled and photographed by Peter Dombrovskis In 1989 a survey of the river valley was undertaken to check for aboriginal sites. Seven archaeological sites were identified.

Olegas Truchanas
Olegas Truchanas (22 September 1923 – 6 January 1972) was a Lithuanian- Australian conservationist and nature photographer. He was a key figure in the attempt to stop the damming of the ecologically sensitive Lake Pedder in South West Tasmania by the Hydro Electricity Commission. His photographs, along with those of his protégé, Peter Dombrovskis, helped raise public awareness of the importance of the south-west Tasmania. Early life Truchanas was born in Lithuania. In 1941, he graduated from the Šiauliai Gymnasium. After the 1945 fall of Lithuania to the USSR, he fled to Munich, Germany. Though he enrolled in a law degree at UNRRA University, he was sent to a displaced persons camp, and subsequently migrated to Tasmania in 1948. Upon arriving in Tasmania, Truchanas worked for a zinc company in Hobart for two years, as was necessary under Australian migration law of the time. At that time, he began to take an interest in the Tasmanian wilderness. South West Tasmania ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gordon Splits
The Gordon Splits is a notable section of gorges of the Gordon River, located in South West Tasmania, Australia. The once impassable gorges are situated on the lower Gordon River in the Franklin-Gordon Wild Rivers National Park, part of the Tasmanian Wilderness World Heritage Area. The splits has also been an important location of focus within the larger environmental campaign for wilderness preservation in South West Tasmania. Location and features The earlier works of Charles Whitham and others suggested that the river went underground at some point. It was not until in 1928 that three piners (J.Hadmar Sticht, G.W. Harrison and Charles Abel) were described as having passed through them in March of that year. It was reported in the Mercury newspaper of 12 April 1928 under the title '' The Gordon River - Exploration of the Splits - Showplace of Tasmania - Sprent Falls alone worth the trip''. The section of river is very difficult to access and apart from Olegas Truchanas, Les ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gordon Power Station, Tasmania
The Gordon Dam, also known as the Gordon River Dam, is a major gated double curvature concrete arch dam with a controlled spillway across the Gordon River, located in South West Tasmania, Australia. The impounded reservoir is called Lake Gordon. The dam was constructed in 1974 by the Hydro Electric Corporation (TAS) for the purpose of generating hydro-electric power via the conventional Gordon Power Station located below the dam wall. Features and location The Gordon Dam wall, constructed with of concrete, is long and high, making it the tallest dam in Tasmania and the fifth-tallest in Australia. At 100% capacity the dam wall holds back of water; making Lake Gordon the largest lake in Australia. The surface area of the lake is and the catchment area is . The single controlled spillway is capable of discharging . Approximately 48 arch dams have been built in Australia and only nine have double curvature. Gordon Dam is almost twice the height of the next highest arch dam, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydro-electric
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.

Lake Pedder
Lake Pedder, once a glacial outwash lake, is a man-made impoundment and diversion lake located in the southwest of Tasmania, Australia. In addition to its natural catchment from the Frankland Range, the lake is formed by the 1972 damming of the Serpentine and Huon rivers by the Hydro Electric Commission of Tasmania for the purposes of hydroelectric power generation. As a result, the flooded Lake Pedder now has a surface area of approximately , making it Tasmania's second largest lake. The original and modified lake In early 20th century the original lake was named after Sir John Pedder, the first Chief Justice of Tasmania. The name of the original lake was officially transferred to the new man-made impoundment. Although the new Lake Pedder incorporates the original lake, it does not resemble it in size, appearance or ecology. The new lake consists of an impoundment contained by three dams: * Serpentine Dam – a high rockfill dam with a concrete upstream face on th ...

Reservoir
A reservoir (; from French ''réservoir'' ) is an enlarged lake behind a dam. Such a dam may be either artificial, built to store fresh water or it may be a natural formation. Reservoirs can be created in a number of ways, including controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, through excavation, or building any number of retaining walls or levees. In other contexts, "reservoirs" may refer to storage spaces for various fluids; they may hold liquids or gasses, including hydrocarbons. ''Tank reservoirs'' store these in ground-level, elevated, or buried tanks. Tank reservoirs for water are also called cisterns. Most underground reservoirs are used to store liquids, principally either water or petroleum. Types Dammed valleys Dammed reservoirs are artificial lakes created and controlled by a dam constructed across a valley, and rely on the natural topography to provide most of the basin ...

Perennial River
A perennial stream is a stream that has continuous flow of surface water throughout the year in at least parts of its catchment during seasons of normal rainfall, Water Supply Paper 494. as opposed to one whose flow is intermittent. In the absence of irregular, prolonged or extreme drought, a perennial stream is a watercourse, or segment, element or emerging body of water which continually delivers groundwater. For example, an artificial disruption of stream, variability in flow or stream selection associated with the activity in hydropower installations, do not affect this status. Perennial streams do not include stagnant water ( pools and waterholes), reservoirs, cutoff lakes and ponds that persist throughout the year. All other streams, or parts of them, should be considered seasonal rivers or lakes. The stream can cycle from intermittent to perpetual through multiple iterations. Stream Definition The basic concept means flowing bodies of water. In hydrology, the st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
