Aroona Dam
Aroona Dam is a reservoir in the Australian state of South Australia located in the gazetted locality of Leigh Creek about west of the locality’s town centre. The dam consists of a concrete gravity dam of a height of and a width of which holds back a lake of a volume of and which extends for a distance about to the east of the dam wall. The origin of its name is not mentioned in sources. However, the word ‘Aroona’ is listed in the official government place name gazetteer as the name of some geographic features either adjoining the dam or located within its extent. A mountain, Mount Aroona, is located in the ridge on the north side of the dam’s lake. A former water feature is now located “under the waters of the Aroona Dam” is named as the Aroona Waterhole as well as having the Adnyamathanha name of Arrunha Awi. It was designed and built by the Electricity Trust of South Australia from 1952 to 1957 by damming the Arrunha Creek (also known as Aroona Creek i ...

Leigh Creek, South Australia
Leigh Creek is a former coal-mining town in eastern central South Australia. At the 2016 census, Leigh Creek had a population of 245, a 55% decrease from 550 in the previous census in 2011. Situated to the west of the northern Flinders Ranges, the current town is 13 km further south than the original town—it was moved in 1982 to allow for the expansion of the mine. As a result, most facilities and buildings in the town are only a little over thirty years old, and with relatively modern designs. The mine and associated railway station are named Telford. History The area was named Leigh's Creek after its first settler, Harry Leigh, in 1856. Coal was discovered and small quantities mined from 1888 from an underground mine. The town to support the mine at that time was called Copley, after William Copley, an MP and Commissioner of Crown Lands. However the coal was not mined in a significant commercial manner until 1943 in an effort to make South Australia more self-su ...

Aroona Sanctuary
Aroona Sanctuary is a private protected area in the Australian state of South Australia located in the gazetted localities of Leigh Creek and Puttapa and whose north-western boundary is within of the locality’s town centre. The sanctuary occupies crown land in the cadastral units of the part section 373, and sections 641 and 1290, all identified as being "Out of Hundreds (COPLEY)." It occupies most of the land in the locality of Leigh Creek including the Aroona Dam with exception to land in the locality's north used for the township and the Leigh Creek Airport, the alignments of The Outback Highway and the Marree railway line, and some land at the locality’s southern boundary. Part of its extent was within the boundaries of the Myrtle Springs Station and was used for the grazing of sheep during this tenure. It was declared as ‘sanctuary’ under the ''National Parks and Wildlife Act 1972'' by the Government of South Australia on 26 October 1995. In 1996, it was the ...

Dams Completed In 1957
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] |
Reservoirs In South Australia
A reservoir (; from French ''réservoir'' ) is an enlarged lake behind a dam. Such a dam may be either artificial, built to store fresh water or it may be a natural formation. Reservoirs can be created in a number of ways, including controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, through excavation, or building any number of retaining walls or levees. In other contexts, "reservoirs" may refer to storage spaces for various fluids; they may hold liquids or gasses, including hydrocarbons. ''Tank reservoirs'' store these in ground-level, elevated, or buried tanks. Tank reservoirs for water are also called cisterns. Most underground reservoirs are used to store liquids, principally either water or petroleum. Types Dammed valleys Dammed reservoirs are artificial lakes created and controlled by a dam constructed across a valley, and rely on the natural topography to provide most of the basin of the re ...

Gravity Dams
A gravity dam is a dam constructed from concrete or stone masonry and designed to hold back water by using only the weight of the material and its resistance against the foundation to oppose the horizontal pressure of water pushing against it. Gravity dams are designed so that each section of the dam is stable and independent of any other dam section. Characteristics Gravity dams generally require stiff rock foundations of high bearing strength (slightly weathered to fresh), although in rare cases, they have been built on soil foundations. The bearing strength of the foundation limits the allowable position of the resultant force, influencing the overall stability. Also, the stiff nature of the gravity dam structure is unforgiving to differential foundation settlement, which can induce cracking of the dam structure. Gravity dams provide some advantages over embankment dams, the main advantage being that they can tolerate minor over-topping flows without damage, as the concre ...

Film Australia
Film Australia was a company established by the Government of Australia to produce films about Australia in 1973. Its predecessors were the Cinema and Photographic Branch (1913–38), the Australian National Film Board (1939–1955, under different departments), and the Commonwealth Film Unit (1956–72). Film Australia became Film Australia Limited in 1988 and was consolidated into Screen Australia in 2008. Administration of the Film Australia Collection was transferred from Screen Australia to the National Film and Sound Archive of Australia on 1 July 2011. The mission of the organisation changed through its earlier incarnations, but from 1973 its aim was to create an audio-visual record of Australian culture, through the commissioning, distribution and management of programs that deal with matters of national interest or illustrate and interpret aspects of Australian life. History In 1913 the Cinema and Photographic Branch (also known as the Cinema Branch) was created in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Desalination
Desalination is a process that takes away mineral components from saline water. More generally, desalination refers to the removal of salts and minerals from a target substance, as in Soil salinity control, soil desalination, which is an issue for agriculture. Saline water, Saltwater (especially Seawater, sea water) is desalinated to produce water suitable for Drinking water, human consumption or irrigation. The by-product of the desalination process is brine. Desalination is used on many seagoing ships and submarines. Most of the modern interest in desalination is focused on cost-effective provision of fresh water for human use. Along with recycled wastewater, it is one of the few rainfall-independent water resources. Due to its energy consumption, desalinating sea water is generally more costly than fresh water from surface water or groundwater, Reclaimed water, water recycling and water conservation. However, these alternatives are not always available and depletion of reserve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
