Ohakuri Dam
Ohakuri is a dam and hydroelectric power station on the Waikato River, central North Island, New Zealand, midway between Taupo, Rotorua and Hamilton. Its dam is about upstream of the Atiamuri Dam. It was commissioned in 1961 and construction was organised from the 'hydro town' of Mangakino.Section 16.3 (from th Pouakani Report 1993 . Accessed 2008-01-16.) The dam eventually created |
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 ...

Dams In New Zealand
Many of the largest dams and reservoirs in New Zealand have been developed principally to produce hydroelectricity. Other uses include irrigation and municipal water supply. Hydro-electric dams The main river systems comprising a series of dams and powerhouses are situated on the following rivers: :The Waikato River :The Waitaki River :The Clutha River Other schemes are standalone developments associated with specific sites. Tongariro Power Scheme The Tongariro Power Scheme (1,400 GWh) diverts water from the south side of Mount Ruapehu and the west and north sides of Tongariro into Lake Taupō, and thus eventually into the Waikato River. *Rangipo (cavern) (120 MW) *Tokaanu (240 MW) * Moawhango Dam The Waikato The hydro stations, starting from Lake Taupō, are (capacity in MW and nominal annual energy output in GWh): * Aratiatia (84 MW) (331 GWh) * Ohakuri (112 MW) (400 GWh) * Atiamuri (84 MW) (305 GWh) *Whakamaru (100 MW) (486 GWh) *Maraetai (360 MW) (855 GWh) *Waipapa (51 ...

Buildings And Structures In Waikato
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artistic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dams Completed In 1961
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] |
Penstock
A penstock is a sluice or gate or intake structure that controls water flow, or an enclosed pipe that delivers water to hydro turbines and sewerage systems. The term is inherited from the earlier technology of mill ponds and watermills. Hydroelectric systems and dams Penstocks for hydroelectric installations are normally equipped with a gate system and a surge tank. They can be a combination of many components such as anchor block, drain valve, air bleed valve, and support piers depending on the application. Flow is regulated by turbine operation and is nil when turbines are not in service. Penstocks, particularly where used in polluted water systems, need to be maintained by hot water washing, manual cleaning, antifouling coatings, and desiccation. The term is also used in irrigation dams to refer to the channels leading to and from high-pressure sluice gates. Penstocks are also used in mine tailings dam construction. The penstock is usually situated fairly close to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ngāti Tahu
Iwi () are the largest social units in New Zealand Māori society. In Māori roughly means "people" or "nation", and is often translated as "tribe", or "a confederation of tribes". The word is both singular and plural in the Māori language, and is typically pluralised as such in English. groups trace their ancestry to the original Polynesian migrants who, according to tradition, arrived from Hawaiki. Some cluster into larger groupings that are based on (genealogical tradition) and known as (literally "canoes", with reference to the original migration voyages). These super-groupings generally serve symbolic rather than practical functions. In pre-European times, most Māori were allied to relatively small groups in the form of ("sub-tribes") and ("family"). Each contains a number of ; among the of the Ngāti Whātua iwi, for example, are Te Uri-o-Hau, Te Roroa, Te Taoū, and Ngāti Whātua-o-Ōrākei.

Māori People
The Māori (, ) are the indigenous Polynesian people of mainland New Zealand (). Māori originated with settlers from East Polynesia, who arrived in New Zealand in several waves of canoe voyages between roughly 1320 and 1350. Over several centuries in isolation, these settlers developed their own distinctive culture, whose language, mythology, crafts, and performing arts evolved independently from those of other eastern Polynesian cultures. Some early Māori moved to the Chatham Islands, where their descendants became New Zealand's other indigenous Polynesian ethnic group, the Moriori. Initial contact between Māori and Europeans, starting in the 18th century, ranged from beneficial trade to lethal violence; Māori actively adopted many technologies from the newcomers. With the signing of the Treaty of Waitangi in 1840, the two cultures coexisted for a generation. Rising tensions over disputed land sales led to conflict in the 1860s, and massive land confiscations, to which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orakei Korako
Orakei Korako is a highly active geothermal area most notable for its series of fault-stepped sinter terraces, located in a valley north of Taupō on the banks of the Waikato River in the Taupō Volcanic Zone, New Zealand. It is also known as "The Hidden Valley".Bain et al. (2006) pp.293, 308 The New Zealand Ministry for Culture and Heritage gives a translation of "place of adornment near the white inter flat for . History of the region From earliest times the Waikato Valley near Orakei Korako was occupied by Māori of the Ngāti Tahu sub-tribe of Tuwharetoa. By the early 19th century the Māori population had congregated at Orakei Korako, probably attracted by the hot springs, which they used for cooking and bathing. Around 1819, the local Māori hid in an alum cave on the site from a passing raiding party of Ngapuhi and Ngati Paoa. The date when the Ngāti Tahu vacated the valley to settle at other locations is not recorded, but it has been suggested that they left after ...
