Wilberforce River
The Wilberforce River is a river in the Southern Alps of New Zealand. It is located in western Canterbury and is naturally a tributary of the Rakaia River, but like the Harper River, it has had some of its flow diverted into Lake Coleridge as part of a hydroelectricity project. This diversion boosted the output of the Coleridge Power Station and was established in 1977. An early proposal for the route of the Midland Line railway from Christchurch to Westland involved extending the Whitecliffs Branch to the West Coast via the Wilberforce River and Browning's Pass. This was one of the proposals rejected in favour of a route via Arthur's Pass Arthur's Pass, previously called Camping Flat then Bealey Flats, and for some time officially Arthurs Pass, is a township in the Southern Alps of the South Island of New Zealand, located in the Selwyn district.

Southern Alps (New Zealand)
The Southern Alps (; officially Southern Alps / Kā Tiritiri o te Moana) is a mountain range extending along much of the length of New Zealand's South Island, reaching its greatest elevations near the range's western side. The name "Southern Alps" generally refers to the entire range, although separate names are given to many of the smaller ranges that form part of it. The range includes the South Island's Main Divide, which separates the water catchments of the more heavily populated eastern side of the island from those on the west coast. Politically, the Main Divide forms the boundary between the Marlborough, Canterbury and Otago regions to the southeast and the Tasman and West Coast regions to the northwest. Names The Māori name of the range is , meaning "the Mirage of the Ocean". The English explorer James Cook bestowed the name ''Southern Alps'' on 23 March 1770, admiring their "prodigious height". p. 384. They had previously been noted by Abel Tasman in 1642, whose ...

Rakaia River
The Rakaia River is in the Canterbury Plains in New Zealand's South Island. The Rakaia River is one of the largest braided rivers in New Zealand. The Rakaia River has a mean flow of and a mean annual seven-day low flow of . In the 1850s, European settlers named it the ''Cholmondeley River'', but this name lapsed into disuse. Description It rises in the Southern Alps, travelling in a generally easterly or southeasterly direction before entering the Pacific Ocean south of Christchurch. It forms a hapua as it reaches the ocean. For much of its journey, the river is braided river, braided, running through a wide shingle bed. Close to Mount Hutt, however, it is briefly confined to a narrow canyon known as the Rakaia Gorge. The Rakaia River is bridged in two places. The busiest crossing is at the small town of Rakaia, from the river mouth, where State Highway 1 (New Zealand), State Highway 1 using Rakaia Bridge and the South Island Main Trunk Railway cross the river using sepa ...

New Zealand
New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island country by area, covering . New Zealand is about east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs ...

Tributary
A tributary, or affluent, is a stream or river that flows into a larger stream or main stem (or parent) river or a lake. A tributary does not flow directly into a sea or ocean. Tributaries and the main stem river drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean. The Irtysh is a chief tributary of the Ob river and is also the longest tributary river in the world with a length of . The Madeira River is the largest tributary river by volume in the world with an average discharge of . A confluence, where two or more bodies of water meet, usually refers to the joining of tributaries. The opposite to a tributary is a distributary, a river or stream that branches off from and flows away from the main stream. PhysicalGeography.net, Michael Pidwirny & S ...

Harper River
The Harper River is a tributary of the Wilberforce River which itself flows into the Rakaia River in New Zealand's Canterbury region. It is located in the Southern Alps and a pass in the Harper River headwaters leads into the Waimakariri River catchment. One of the most popular tramping routes in Canterbury enters the East Harper via Cass Saddle and exits via Lagoon Saddle at the head of the West Harper. The waters of the Harper River and its major tributary, the Avoca River, are channelled into Lake Coleridge via a structure known as the Harper Diversion which was constructed in 1921 as part of a hydroelectricity project. The Harper Avoca catchment has been the site of much ecological research since the mid-1950s. It is well serviced by huts on Lagoon and Cass Saddles, the West Harper, Hamilton Hut at the junction of the two branches of the Harper, Avoca Hut in the headwaters of the Avoca, two huts at Back Basins Creek, a small two man hut up Back Basins Creek and a larger hut ...

Lake Coleridge
Lake Coleridge ( mi, Whakamatau) is located in inland Canterbury, in New Zealand's South Island. Located to the northwest of Methven, it has a surface area of . The lake is situated in an over-deepened valley formed by a glacier over 20,000 years ago in the Pleistocene era. It currently has no natural outflows. There is a small settlement at the lake. Ecology Early colonial explorers found the shores of the lake covered in mānuka (or kānuka), kōwhai, cabbage trees, flax and general swamp plants. The lake was also surrounded by Southern Rata trees, and native beech trees. The lake itself was fairly lacking in aquatic plants due to a lack of nutrients. The lake was known for a population of large eels. Human activity has significantly changed the ecology. Colonial settlers introduced game fish including rainbow trout, brown trout, Atlantic salmon and Chinook salmon. The changing water levels caused by the operation of the Coleridge Power Station killed most of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydroelectricity
Hydroelectricity, or hydroelectric power, is Electricity generation, 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 energy, renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of Low-carbon power, 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.

Midland Line, New Zealand
The Midland line is a 212 km section of railway between Rolleston and Greymouth in the South Island of New Zealand. The line features five major bridges, five viaducts and 17 tunnels, the longest of which is the Otira tunnel. It is the route of the popular TranzAlpine passenger train. History Railway development in the South Island in the 1870s was concentrated on a main line linking the established centres of Christchurch, Timaru, Dunedin and Invercargill and light, easily constructed branch lines serving the arable plains; (see Vogel Era). These later included a branch to Springfield which was reached by January 1880. In 1882 the East and West Coast Railway League was formed and in 1884 a Royal Commission, although fully aware of the construction difficulties of the Waimakariri Valley-Arthurs Pass route, as compared with the somewhat easier but longer Hurunui Valley-Harpers Pass route, chose the more direct route. The construction of the line was rejected in 1883 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer facilit ...
