Salt River (Western Australia)
Salt River is a river in the Wheatbelt region of Western Australia. It is a tributary of the Avon River, taking water from two of the Avon's sub-catchments, the Yilgarn River and the Lockhart River, from their junction where it passes through a hydrological-topographical pinch-point at Caroline Gap. From here it flows south-west past Quairading, about before discharging into the Yenyening Lakes northeast of Brookton. These in turn discharge into the Avon River, which discharges into the Swan River and its estuary, which discharges into the Indian Ocean. Salt River, and all its tributaries, is a saline river system comprising a chain of salt lakes. Its southern, Lockhart tributaries arise in the vicinity of Lake Grace, Newdegate and Lake King, whilst its Yilgarn tributaries arise north and east of Southern Cross Crux () is a constellation of the southern sky that is centred on four bright stars in a cross-shaped asterism commonly known as the Southern Cross.

Wheatbelt (Western Australia)
The Wheatbelt is one of nine regions of Western Australia defined as administrative areas for the state's regional development, and a vernacular term for the area converted to agriculture during colonisation. It partially surrounds the Perth metropolitan area, extending north from Perth to the Mid West region, and east to the Goldfields–Esperance region. It is bordered to the south by the South West and Great Southern regions, and to the west by the Indian Ocean, the Perth metropolitan area, and the Peel region. Altogether, it has an area of (including islands). The region has 42 local government authorities, with an estimated population of 75,000 residents. The Wheatbelt accounts for approximately three per cent of Western Australia's population. Ecosystems The area, once a diverse ecosystem, reduced when clearing began in the 1890s with the removal of plant species such as eucalypt woodlands and mallee, is now home to around 11% of Australia's critically end ...

Salinity
Salinity () is the saltiness or amount of salt dissolved in a body of water, called saline water (see also soil salinity). It is usually measured in g/L or g/kg (grams of salt per liter/kilogram of water; the latter is dimensionless and equal to ‰). Salinity is an important factor in determining many aspects of the chemistry of natural waters and of biological processes within it, and is a thermodynamic state variable that, along with temperature and pressure, governs physical characteristics like the density and heat capacity of the water. A contour line of constant salinity is called an ''isohaline'', or sometimes ''isohale''. Definitions Salinity in rivers, lakes, and the ocean is conceptually simple, but technically challenging to define and measure precisely. Conceptually the salinity is the quantity of dissolved salt content of the water. Salts are compounds like sodium chloride, magnesium sulfate, potassium nitrate, and sodium bicarbonate which dissolve into ions ...

Kellerberrin, Western Australia
Kellerberrin is a town in the Wheatbelt region of Western Australia, east of Perth on the Great Eastern Highway. The town serves as a stop on the '' Prospector'' and ''MerredinLink'' rural train services. It is also located on the Golden Pipeline Heritage Trail. History Early settlers from 1890 to 1910 from Ireland settled in the area of Kellerberrin and Wittem. Their family name was English. A road was named after this family. The railway line from Northam to Southern Cross was constructed through here in 1893–94, and this section opened for traffic in 1895. Kellerberrin was one of the original stations when the line opened. By 1898 there was a demand for small blocks of land in the area, and the government surveyed a number of lots the same year. The area was gazetted as Kellerberrin townsite in 1901, and the government soon made more land available for settlers. In 1898 the Agricultural Hall was officially opened. It was built with granite walling and brick dressing w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Merredin, Western Australia
Merredin is a town in Western Australia, located in the central Wheatbelt (Western Australia), Wheatbelt roughly midway between Perth and Kalgoorlie, Western Australia, Kalgoorlie, on List of road routes in Perth, Western Australia, Route 94, Great Eastern Highway. It is located on the route of the Goldfields Water Supply Scheme, and as a result is also on the Golden Pipeline Heritage Trail. It is connected by public transport to Perth via the'' The Prospector (train), Prospector'' and ''MerredinLink'' rail services. History Merredin's history varies from that of other wheat-belt towns in Western Australia in the sense that it started as a stopping place on the way to the Goldfields-Esperance region of Western Australia, goldfields. The first European explorer into the area was the Surveyor General of Western Australia, Surveyor General John Septimus Roe, J. S. Roe, who travelled through the region in 1836 but was not impressed by its dryness and the low rainfall. By the 1850s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern Cross, Western Australia
Southern Cross is a town in Western Australia, 371 kilometres east of state capital Perth on the Great Eastern Highway. It was founded by gold prospectors in 1888, and gazetted in 1890. It is the major town and administrative centre of the Shire of Yilgarn. At the , Southern Cross had a population of 680. The town of Southern Cross is one of the many towns that run along the Goldfields Water Supply Scheme pipeline from Mundaring to Kalgoorlie, engineered by C. Y. O'Connor, and as a consequence is an important location on the Golden Pipeline Heritage Trail. A succession of gold rushes in the Yilgarn region near Southern Cross in 1887, at Coolgardie in 1892, and at Kalgoorlie in 1893 caused a population explosion in the barren and dry desert centre of Western Australia. It is named after the Southern Cross constellation, and the town's streets are named after constellations and stars. The surrounding areas produce wheat and other cereal crops. The town is a receival site for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake King, Western Australia
Lake King is a town in the eastern Wheatbelt region of Western Australia, from Perth along State Route 40 between Kelmscott and Ravensthorpe. As of 2016, the town had a population of 95. The 2011 census recorded both the population of the town and the surrounding area for a population of 332. Lake King is named after a nearby lake which in turn was named after the Surveyor General of Western Australia, Henry Sandford King, by Marshall Fox, District Surveyor (Narrogin). In 1926, following completion of an initial land classification survey of the Lake King district that defined 230,000 acres as suitable for settlement, a large official inspection party was led by Surveyor General John Percy Camm, Sydney Stubbs ( MLA Wagin), Edwin Wilkie Corboy (MLA Yilgan), and James Cornell ( MLC South Province). The area was surveyed and access roads built during 1927, and land released in 1928 at prices from 4/6 to 16/- per acre. The town struggled through the depression but thrived in th ...

Newdegate, Western Australia
Newdegate is a townsite in the Great Southern agricultural region, 399 km south-east of Perth and 52 km east of Lake Grace in Western Australia. The townsite was gazetted in 1925 and honours Sir Francis Newdegate, the Governor of Western Australia from 1920 to 1924. The Department of Agriculture and Food operates one of its 13 research stations in the area of Newdegate. Newdegate is situated in the heart of the south-eastern wheatbelt of Western Australia – about halfway between Perth in the west and Esperance in the south-east. It is a very successful grain and sheep farming area. Newdegate is central to the Western Mallee subregion of the Interim Biogeographic Regionalisation for Australia. It is a sparsely populated subregion with an area of about . The local hall was opened in 1926 by Mr. B Carruthers from Lake Grace. A gold reef was found to the north east of town the same year. In 1932 the Wheat Pool of Western Australia announced that the town would have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Grace, Western Australia
Lake Grace is a town in the eastern Wheatbelt region of Western Australia, from Perth along State Route 107 between Wagin and Ravensthorpe. It is the main town in the Shire of Lake Grace. At the 2016 census, Lake Grace had a population of 507. History The area was first taken up for agriculture around 1911. In 1913 a school was established and named Lake Grace after the nearby lake. In 1914 the government planned to extend the railway network from Kukerin to Lake Grace, and local settlers lobbied for a townsite to be declared at the terminus. The railway was completed on 25 November 1916, and terminated close to the site of the existing school. The townsite of Lake Grace was gazetted later in 1916. The branch railway was extended to the ultimate terminus at Newdegate on 15 February 1926 and a further branch from Lake Grace to Hyden opened on 5 April 1933, making Lake Grace a junction and therefore of some importance for train working operations.

Salt Lake
A salt lake or saline lake is a landlocked body of water that has a concentration of salts (typically sodium chloride) and other dissolved minerals significantly higher than most lakes (often defined as at least three grams of salt per litre). In some cases, salt lakes have a higher concentration of salt than sea water; such lakes can also be termed hypersaline lakes, and may also be pink lakes on account of their colour. An alkalic salt lake that has a high content of carbonate is sometimes termed a soda lake. One saline lake classification differentiates between: *subsaline: 0.5–3‰ (0.05-0.3%) *hyposaline: 3–20‰ (0.3-2%) *mesosaline: 20–50‰ (2-5%) *hypersaline: greater than 50‰ (5%) Properties Salt lakes form when the water flowing into the lake, containing salt or minerals, cannot leave because the lake is endorheic (terminal). The water then evaporates, leaving behind any dissolved salts and thus increasing its salinity, making a salt lake an excellent place ...

Indian Ocean
The Indian Ocean is the third-largest of the world's five oceanic divisions, covering or ~19.8% of the water on Earth's surface. It is bounded by Asia to the north, Africa to the west and Australia to the east. To the south it is bounded by the Southern Ocean or Antarctica, depending on the definition in use. Along its core, the Indian Ocean has some large marginal or regional seas such as the Arabian Sea, Laccadive Sea, Bay of Bengal, and Andaman Sea. Etymology The Indian Ocean has been known by its present name since at least 1515 when the Latin form ''Oceanus Orientalis Indicus'' ("Indian Eastern Ocean") is attested, named after Indian subcontinent, India, which projects into it. It was earlier known as the ''Eastern Ocean'', a term that was still in use during the mid-18th century (see map), as opposed to the ''Western Ocean'' (Atlantic Ocean, Atlantic) before the Pacific Ocean, Pacific was surmised.

Swan River (Western Australia)
The Swan River () is a river in the south west of Western Australia. The river runs through the metropolitan area of Perth, Western Australia's capital and largest city. Course of river The Swan River estuary flows through the city of Perth. Its lower reaches are relatively wide and deep, with few constrictions, while the upper reaches are usually quite narrow and shallow. The Swan River drains the Avon and coastal plain catchments, which have a total area of about . It has three major tributaries, the Avon River, Canning River and Helena River. The latter two have dams (Canning Dam and Mundaring Weir) which provide a sizeable part of the potable water requirements for Perth and the regions surrounding. The Avon River contributes the majority of the freshwater flow. The climate of the catchment is Mediterranean, with mild wet winters, hot dry summers, and the associated highly seasonal rainfall and flow regime.
