Waipā River
The Waipā River is in the Waikato region of the North Island of New Zealand. The headwaters are in the Rangitoto Range east of Te Kūiti. It flows north for , passing through Ōtorohanga and Pirongia, before flowing into the Waikato River at Ngāruawāhia. It is the Waikato's largest tributary. The Waipā's main tributary is the Puniu River. In the headwaters upstream of Ōtorohanga the river can be very clear during low flow conditions. This section of the river flows through rough farmland and patches of native bush. In this clearer part of the river there can be very good fly fishing for trout but access to the river may be limited without landowner permission. The Waipā is prone to flooding in its lower reaches as flood flows can be over 100 times——those of dry flows and the river can rise up to . In 2013 Maniapoto Māori Trust Board and the riparian local councils set up a joint management agreement for the river, following the passing of Nga Wai o Ma ...

Hakarimata Range
Hakarimata Range is a range of hills on the western edge of Ngāruawāhia township, Retrieved 2016 in the Waikato region of New Zealand, overlooking the confluence of the Waikato and Waipā Rivers. The Hakarimata Range is separated from the Taupiri Range by the Taupiri Gorge, through which the Waikato River flows. After the invasion of the Waikato, parts of the Hakarimatas were confiscated in 1864. of native forest on the range are protected as a scenic reserve. A council supported community group, the Hakarimata Restoration Trust, created in 2001, is helping care for the range. Location Although now usually applied to the hills immediately west of Ngāruawāhia, maps such as Hochstetter's of 1859, the 1925 geology map and 1944 one inch map show 'Hakarimata Range' as extending south to what is now SH23. Similarly, old accounts describe the Whatawhata- Raglan road as passing over the Hakarimatas. Name Hakarimata's name derives from a 17th-century feast, when Ngāti Ma ...

Map Of The Waipa Valley 2021-08-25
A map is a symbolic depiction of interrelationships, commonly spatial, between things within a space. A map may be annotated with text and graphics. Like any graphic, a map may be fixed to paper or other durable media, or may be displayed on a transitory medium such as a computer screen. Some maps change interactively. Although maps are commonly used to depict geographic elements, they may represent any space, real or fictional. The subject being mapped may be two-dimensional such as Earth's surface, three-dimensional such as Earth's interior, or from an abstract space of any dimension. Maps of geographic territory have a very long tradition and have existed from ancient times. The word "map" comes from the , wherein ''mappa'' meant 'napkin' or 'cloth' and ''mundi'' 'of the world'. Thus, "map" became a shortened term referring to a flat representation of Earth's surface. History Maps have been one of the most important human inventions for millennia, allowing humans t ...

Turbidity
Turbidity is the cloudiness or haziness of a fluid caused by large numbers of individual particles that are generally invisible to the naked eye, similar to smoke in air. The measurement of turbidity is a key test of both water clarity and water quality. Fluids can contain suspended solid matter consisting of particles of many different sizes. While some suspended material will be large enough and heavy enough to settle rapidly to the bottom of the container if a liquid sample is left to stand (the settable solids), very small particles will settle only very slowly or not at all if the sample is regularly agitated or the particles are colloidal. These small solid particles cause the liquid to appear turbid. Turbidity (or haze) is also applied to transparent solids such as glass or plastic. In plastic production, haze is defined as the percentage of light that is deflected more than 2.5° from the incoming light direction. Causes and effects Turbidity in open water may be ca ...

Escherichia Coli
''Escherichia coli'' ( )Wells, J. C. (2000) Longman Pronunciation Dictionary. Harlow ngland Pearson Education Ltd. is a gram-negative, facultative anaerobic, rod-shaped, coliform bacterium of the genus '' Escherichia'' that is commonly found in the lower intestine of warm-blooded organisms. Most ''E. coli'' strains are part of the normal microbiota of the gut, where they constitute about 0.1%, along with other facultative anaerobes. These bacteria are mostly harmless or even beneficial to humans. For example, some strains of ''E. coli'' benefit their hosts by producing vitamin K2 or by preventing the colonization of the intestine by harmful pathogenic bacteria. These mutually beneficial relationships between ''E. coli'' and humans are a type of mutualistic biological relationship—where both the humans and the ''E. coli'' are benefitting each other. ''E. coli'' is expelled into the environment within fecal matter. The bacterium grows massi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whatawhata
Whatawhata, previously also spelt Whata Whata, is a small town in the Waikato region on the east bank of the Waipā River, at the junction of New Zealand State Highway 23, State Highways 23 and New Zealand State Highway 39, 39, from Hamilton, New Zealand, Hamilton. Te Araroa tramping route passes through Whatawhata. History and culture Pre-European history Whatawhata was a Ngāti Māhanga village and there are still Te Papa-o-Rotu and Ōmaero maraes on the west bank of the river. In early colonial times Whatawhata was one of many Waikato#History, sites in Waikato with a flour mill. It was built in 1855 and producing flour by the end of that year. The area must have been suited to wheat, for there was another mill about downstream, at Karakariki, by 1860. European settlement British troops arrived at Whatawhata over land and by river, as part of the Invasion of the Waikato, on 28 December 1863. Whatawhata was described as having no end of peach trees, which the soldiers stri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water Pollution In New Zealand
Water pollution in New Zealand is an increasing concern for those who use and care for waterways and for New Zealand regulatory bodies. An increase in population is linked to an increase in water pollution, due to a range of causes such as rural land use, industrial use and urban development. Fresh water quality is under pressure from agriculture, hydropower, urban development, pest invasions and climate change. While pollution from point sources has been reduced, diffuse pollution such as nutrients, pathogens and sediments development and from stormwater in towns is not under control. There are more than 800 water quality monitoring sites around New Zealand that are regularly sampled. , Auckland is the region with New Zealand's most polluted waterways, with 62% of rivers and lakes graded poor by the Ministry for the Environment for swimming, and 0% of rivers and lakes graded as good. In 2018, waterways across New Zealand have been showing improvements across a number of water q ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Load Following Power Plant
A load-following power plant, regarded as producing mid-merit or mid-priced electricity, is a power plant that adjusts its power output as demand for electricity fluctuates throughout the day. Load-following plants are typically in between base load and peaking power plants in efficiency, speed of start-up and shut-down, construction cost, cost of electricity and capacity factor. Base load and peaking power plants Base load power plants are dispatchable plants that tend to operate at maximum output. They generally shut down or reduce power only to perform maintenance or repair or due to grid constraints. Power plants operated mostly in this way include coal, fuel oil, nuclear, geothermal, run-of-the-river hydroelectric, solar, biomass and combined cycle natural gas plants. Peaking power plants operate only during times of peak demand. In countries with widespread air conditioning, demand peaks around the middle of the afternoon, so a typical peaking power plant may s ...

Maui Gas Field
The Maui natural gas field is the largest gas, natural gas condensate and oil field in New Zealand, producing nearly three-quarters of the country's hydrocarbons, as well as providing energy for electricity generation. It is located in the Tasman Sea, 35 km off the coast of Taranaki Region, Taranaki and to the southwest of New Plymouth. It covers an area of 157 square kilometres and is located in 110 metres of water. The gas field was discovered in 1969 by a joint venture of Royal Dutch Shell, Royal Dutch/Shell, BP, British Petroleum and Todd Corporation, Todd Petroleum. It was considered a "giant" field at the time of discovery. Government investment led to a government organisation later called Petrocorp taking a 50% interest. This was later bought out by Fletcher Challenge Energy. By the end of the Maui gas contract in 2009, the Maui Mining Companies were made up of Shell Oil Company, Shell (83.75%), OMV New Zealand (10%), and Todd Energy (6.25%). OMV New Zealand owns a ...

Gas Turbine
A gas turbine or gas turbine engine is a type of Internal combustion engine#Continuous combustion, continuous flow internal combustion engine. The main parts common to all gas turbine engines form the power-producing part (known as the gas generator or core) and are, in the direction of flow: * a rotating gas compressor * a combustor * a compressor-driving turbine. Additional components have to be added to the gas generator to suit its application. Common to all is an air inlet but with different configurations to suit the requirements of marine use, land use or flight at speeds varying from stationary to supersonic. A propelling nozzle is added to produce thrust for flight. An extra turbine is added to drive a propeller (turboprop) or ducted fan (turbofan) to reduce fuel consumption (by increasing propulsive efficiency) at subsonic flight speeds. An extra turbine is also required to drive a helicopter rotor or land-vehicle transmission (turboshaft), marine propeller or electric ...

Resource Consent
A resource consent is the authorisation given to certain activities or uses of natural and physical resources required under the New Zealand Resource Management Act (the "RMA"). Some activities may either be specifically authorised by the RMA or be permitted activities authorised by rules in plans. Any activities that are not permitted by the RMA, or by a rule in a plan, require a resource consent before they are carried out. Definition and nature The term "resource consent" is defined as; * a permit to carry out an activity that would otherwise contravene a rule in a city or district plan. * a permission required for an activity that might affect the environment, and that isn't allowed 'as of right' in the district or regional plan. A resource consent, once granted to an applicant, is neither real nor personal property. Therefore, resource consents cannot be 'owned'; they are 'held' by 'consent holders'. Types A resource consent means any of the following: * land use consent ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Todd Corporation
The Todd Corporation Limited is a privately held conglomerate based in New Zealand, owned and controlled by the Todd family and headquartered in Wellington, New Zealand. The corporation is currently led by board chair, Nick Olson, and group chief executive officer, Evan Davies. The corporation employs 800 individuals at 10 locations in New Zealand, Australia, and Canada including seven on the executive team. The board of directors has seven members. History The history of Todd Corporation is understood to have begun in 1885 when Scottish immigrant Charles Todd founded and opened a fellmongery and wool scouring business (according to Todd Energy) in the small Central Otago town of Heriot. By 1929, it had evolved into a car sales and maintenance business run by his son and namesake Charles Todd after the company began importing motor vehicles. This automotive business would define the Todd family business until well into the 1980s. Charles Todd was credited with bringing the ...

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 of Scots origin, and was inherited from the earlier technology of mill ponds and watermills, with penstocks diverting pond waters to drive the mills. 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 to suit turbine operation and is cut off 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, allowing waters to go anoxic, and desiccation used to dry fouling out so that it may slough off or become easier to remove through manual processes.
