Serpentine Dam (Western Australia)
The Serpentine Dam is a major water supply dam for Perth, Western Australia. The dam is used to store water that is released at a controlled rate to regulate the level in the Serpentine Pipehead Dam reservoir, which in turn feeds water to the metropolitan trunk main network depending on demand. Construction of the dam was completed in 1961. The Serpentine Dam is one of the 15 dams, some of which have since been decommissioned, that have been built in Western Australia since the 1920s, along with the Serpentine Pipehead Dam. It was built as part of the Integrated Water Supply System (IWSS), the largest scheme currently managed by the Water Corporation, which provides water for over two million people in Perth, Mandurah, and other Western Australian regions. Serpentine Dam is connected to the Serpentine Pipehead Dam, which stores water and desalinated water from the Serpentine Dam and other dams nearby for later use. The Serpentine Dam is an important water source because the Pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Serpentine, Western Australia
Serpentine is a town located south-southeast of Perth, the capital of Western Australia, and 7 km south of Mundijong. Serpentine is located on the South Western Railway between Perth and Bunbury, and was one of the original stations when the line was opened in 1893. The population of the town was 128 (80 males and 48 females) in 1898. At the 2016 census, Serpentine had a population of 1,265. In 1891 the government had opened up land in the area by declaring the Serpentine Agricultural Area, and in 1893 decided there was sufficient demand for town lots by gazetting the Townsite of Serpentine in December 1893. The townsite derives its name from the nearby Serpentine River. The name is descriptive, derived from the "serpentine" nature of the river in its lower reaches where it was discovered and named in the early 1830s. It is the locality to which the BOM weather radar has been shifted following on from the original Perth location in West Perth. The Bodhinyana Buddhist ...

Darling Scarp
The Darling Scarp, also referred to as the Darling Range or Darling Ranges, is a low escarpment running north–south to the east of the Swan Coastal Plain and Perth, Western Australia. The escarpment extends generally north of Bindoon, to the south of Pemberton. The adjacent Darling Plateau goes easterly to include Mount Bakewell near York and Mount Saddleback near Boddington. It was named after the Governor of New South Wales, Lieutenant-General Ralph Darling. History The feature was first recorded as General Darling Range by Charles Fraser, Government Botanist with Captain James Stirling aboard in March 1827. Maps from the 1830s show the scarp labelled " General Darlings Range"; this later became Darling Range, a name by which the formation was still commonly known in the late 20th century despite common understanding of it being an escarpment. There is also a tendency to identify the locations on or to the east of the scarp as being in the "Perth Hills" (or simpl ...

Bauxite
Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and gallium. Bauxite consists mostly of the aluminium minerals gibbsite (Al(OH)3), boehmite (γ-AlO(OH)) and diaspore (α-AlO(OH)), mixed with the two iron oxides goethite (FeO(OH)) and haematite (Fe2O3), the aluminium clay mineral kaolinite (Al2Si2O5(OH)4) and small amounts of anatase (TiO2) and ilmenite (FeTiO3 or FeO.TiO2). Bauxite appears dull in luster and is reddish-brown, white, or tan. In 1821, the French geologist Pierre Berthier discovered bauxite near the village of Les Baux in Provence, southern France. Formation Numerous classification schemes have been proposed for bauxite but, , there was no consensus. Vadász (1951) distinguished lateritic bauxites (silicate bauxites) from karst bauxite ores (carbonate bauxites): * The carbonate bauxites occur predominantly in Europe, Guyana, Suriname, and Jamaica above carbonate rocks (limestone and do ...

Alcoa
Alcoa Corporation (an acronym for Aluminum Company of America) is a Pittsburgh-based industrial corporation. It is the world's eighth-largest producer of aluminum. Alcoa conducts operations in 10 countries. Alcoa is a major producer of primary aluminum, fabricated aluminum, and alumina combined, through its active and growing participation in all major aspects of the industry: technology, mining, refining, smelting, fabricating, and recycling. In May 2007, Alcoa Inc. made a US$27 billion hostile takeover bid for Alcan in an attempt to form the world's largest aluminum producer. The bid was withdrawn when Alcan announced a friendly takeover by Rio Tinto in July 2007. On November 1, 2016, Alcoa Inc. split into two entities: a new one called Alcoa Corporation, which is engaged in the mining and manufacture of raw aluminum, and the renaming of Alcoa Inc. to Arconic Inc., which processes aluminum and other metals. After relocating its corporate operations to New York City in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Climate Change
In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans burning fossil fuels. Fossil fuel use, deforestation, and some agricultural and industrial practices increase greenhouse gases, notably carbon dioxide and methane. Greenhouse gases absorb some of the heat that the Earth radiates after it warms from sunlight. Larger amounts of these gases trap more heat in Earth's lower atmosphere, causing global warming. Due to climate change, deserts are expanding, while heat waves and wildfires are becoming more common. Increased warming in the Arctic has contributed to melting permafrost, glacial retreat and sea ice loss. Higher temperatures are also causing m ...

Australian Height Datum
The Australian Height Datum was introduced in 1971 as the official vertical datum for Australia, and thereby serves as the benchmark to which all height measurements are referred. The Australian Height Datum is an amalgamation of decades of spirit levelling work conducted by numerous state and territory authorities across the country, and was corrected to align with the mean sea level observations of thirty tide gauges positioned around the entire coastline. While it remains the published vertical datum for all surveying and engineering operations performed throughout Australia, newer technologies have uncovered numerous deficiencies, offsets and distortions within the Australian Height Datum, leading to discussions about defining a new Australian vertical datum. Background The National Mapping Council (pre-1945) Prior to the creation of the Australian Height Datum, levelling surveys were carried out by professional surveyors for construction and mapping purposes using only ...

Agricultural
Agriculture or farming is the practice of cultivating Plant, plants and livestock. Agriculture was the key development in the rise of Sedentism, sedentary human civilization, whereby farming of Domestication, domesticated species created food Economic surplus, surpluses that enabled people to live in cities. The history of agriculture began thousands of years ago. After gathering wild grains beginning at least 105,000 years ago, nascent farmers began to plant them around 11,500 years ago. Sheep, goats, pigs and cattle were domesticated over 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. Industrial agriculture based on large-scale monoculture in the twentieth century came to dominate agricultural output, though about 2 billion people still depended on subsistence agriculture. The major agricultural products can be broadly grouped into Food, foods, Fiber, fibers, fuels, and raw materials (such as Natural rubber, rubber). Food clas ...

Woodland
A woodland () is, in the broad sense, land covered with trees, or in a narrow sense, synonymous with wood (or in the U.S., the ''plurale tantum'' woods), a low-density forest forming open habitats with plenty of sunlight and limited shade (see differences between British, American, and Australian English explained below). Woodlands may support an understory of shrubs and herbaceous plants including grasses. Woodland may form a transition to shrubland under drier conditions or during early stages of primary or secondary succession. Higher-density areas of trees with a largely closed canopy that provides extensive and nearly continuous shade are often referred to as forests. Extensive efforts by conservationist groups have been made to preserve woodlands from urbanization and agriculture. For example, the woodlands of Northwest Indiana have been preserved as part of the Indiana Dunes. Definitions United Kingdom ''Woodland'' is used in British woodland management to mean tre ...

Archaean Shield
A shield is a large area of exposed Precambrian crystalline igneous and high-grade metamorphic rocks that form tectonically stable areas. These rocks are older than 570 million years and sometimes date back to around 2 to 3.5 billion years. They have been little affected by tectonic events following the end of the Precambrian, and are relatively flat regions where mountain building, faulting, and other tectonic processes are minor, compared with the activity at their margins and between tectonic plates. Shields occur on all continents. Terminology The term shield cannot be used interchangeably with the term craton. However, shield can be used interchangeably with the term basement. The difference is that a craton describes a basement overlayed by a sedimentary platform while shield only describes the basement. The term ''shield'', used to describe this type of geographic region, appears in the 1901 English translation of ''Eduard Suess's Face of Earth'' by H. B. C. Sollas, a ...
