Barossa Reservoir
Barossa Reservoir is a reservoir in the Australian state of South Australia, built between 1899 and 1902 to supply water to Gawler and other northern country areas. Built at a cost of almost A£170,000 the reservoir was hailed on completion as an engineering marvel, and with the reservoir wall rising to a height of , it was, at the time of its completion, the highest dam wall in Australia. Location and features The thin arch of the dam retaining wall, curved against the pressure of the water, was an innovation considered radical, and attracted the Reservoir international attention. It was featured in the ''Scientific American'' and caused the ''American Engineers News'' to remark that its "boldness of design deserves to rank with the most famous dams in the world". The dam is notable for its parabola effect, where a voice can be heard clearly from one side to the other – over , end to end. This unusual acoustic phenomenon is a popular tourist attraction, and has earned the dam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Williamstown, South Australia
Williamstown is a small South Australian town on the southern fringe of the Barossa Valley wine-growing region. It is 51 km north east of Adelaide and 16 km south-east of Gawler. Williamstown was originally known as ''Victoria Creek''. The township was laid out in 1858 by Lewis Johnston, or Johnstone, on land he purchased in 1857, and named for his son. Williamstown has an elevation of 310 m and an average rainfall of 680 mm. It has a summer average temperature of 31 °C with temperatures often reaching the mid 40s, and a winter average temperature of 15 °C, with nights dropping below freezing, which makes the region excellent for the cultivation of fruits, especially grapes in the lower riverine alluvial deposits. History Williamstown was essentially a farming area with sheep and cattle in the early days with fruit orchards, mixed farms and vines. Williamstown also sustained a forestry and lumber industry from the earliest days with three sawmi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whispering Gallery
The Whispering Gallery of St Paul's Cathedral, London A whispering gallery is usually a circular, hemispherical, elliptical or ellipsoidal enclosure, often beneath a dome or a vault, in which whispers can be heard clearly in other parts of the gallery. Such galleries can also be set up using two parabolic dishes. Sometimes the phenomenon is detected in caves. Theory A whispering gallery is most simply constructed in the form of a circular wall, and allows whispered communication from any part of the internal side of the circumference to any other part. The sound is carried by waves, known as whispering-gallery waves, that travel around the circumference clinging to the walls, an effect that was discovered in the whispering gallery of St Paul's Cathedral in London. The extent to which the sound travels at St Paul's can also be judged by clapping in the gallery, which produces four echoes. Other historical examplesC. V. RamanOn whispering galleries, Proc.

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 ...

Barossa Valley
The Barossa Valley ( Barossa German: ''Barossa Tal'') is a valley in South Australia located northeast of Adelaide city centre. The valley is formed by the North Para River. It is notable as a major wine-producing region and tourist destination. The Barossa Valley Way is the main road through the valley, connecting the main towns on the valley floor of Nuriootpa, Tanunda, Rowland Flat and Lyndoch. The Barossa Trail walking and cycling path is long and also passes the main towns from near Gawler on the Adelaide Plains to Angaston to the east of the valley. History The traditional owners of the land including the Barossa Valley are the Peramangk people, who comprise a number of family groups. Evidence of their thousands of years of occupation can be seen all around the area, in the form of artefacts, scar trees and shelter paintings. The Barossa Valley derives its name from the Barossa Range, which was named by Colonel William Light in 1837. Light chose the name in ...

Engineers Australia
Engineers Australia (EA) is an Australian professional body and not-for-profit organisation whose purpose is to advance the science and practice of engineering for the benefit of the community. Engineers Australia is Australia's recognized organization for accreditation of professional engineering qualifications under the Washington Accord. As of 2022, EA has 115,000 members, which includes 31,000 students. History The organisation began after World War I, following recognition of the need for a single body to represent engineers, rather than the numerous smaller organisations that existed then. The first council meeting was held in 1919, electing Professor William Warren of the University of Sydney as the first President.Lloyd, B E (1968) ''The Education of Professional Engineers in Australia'', APEA Melbourne.Lloyd, B E (1988) "In Search of Identity: Engineering in Australia 1788–1988", Thesis for Doctor of Philosophy, University of Melbourne On 1 May 1926 the Institutio ...

Elizabeth, South Australia
Elizabeth is an outer northern suburb of the Adelaide metropolitan area, South Australia, 24 km north of the Adelaide city centre. It is located in the City of Playford. At the 2016 census, Elizabeth had a population of 1,024. Established in 1955, it was the seat of the former local government body, the Old City of Elizabeth, which included Elizabeth as well as the immediately adjacent suburbs on all sides except the west. Although the City of Elizabeth no longer exists, having been amalgamated into the much larger City of Playford in 1997, the term "Elizabeth", in the context of Adelaide, typically refers to the historic municipality and the distinct community therein. History Before the 1950s, most of the area surrounding today's suburb of Elizabeth was farming land. After the end of the Second World War with its shortage of materials, the state government decided that South Australia needed to grow and become industrialised. A satellite city was planned for northern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Munno Para, South Australia
Munno Para is a northern suburb of Adelaide, South Australia. It is located in the City of Playford. In the local Kaurna dialect, Munno Para means ''golden wattle creek''. The name refers to either the Gawler River (which starts at the confluence of the South Para River and North Para River) or the Little Para River from which the much larger cadastral Hundred of Munno Para derives its name. History Until 1997, Munno Para was part of the City of Munno Para, formerly the district councils of Munno Para East and Munno Para West which were established in 1853 and 1854 on land bounded by the cadastral Hundred of Munno Para. The older part of the suburb itself began from a subdivision in 1955 and the suburb was named in 1978. Until the locality was urbanised from 1955, Munno Para was part of the farming district north of the township of Smithfield. The Andrews Family farmed most of the area west of the Gawler Central Railway Line and what is now Stebonheath Road. The Playford Ali ...

Murray River
The Murray River (in South Australia: River Murray) (Ngarrindjeri: ''Millewa'', Yorta Yorta: ''Tongala'') is a river in Southeastern Australia. It is Australia's longest river at extent. Its tributaries include five of the next six longest rivers of Australia (the Murrumbidgee, Darling, Lachlan, Warrego and Paroo Rivers). Together with that of the Murray, the catchments of these rivers form the Murray–Darling basin, which covers about one-seventh the area of Australia. It is widely considered Australia's most important irrigated region. The Murray rises in the Australian Alps, draining the western side of Australia's highest mountains, then meanders northwest across Australia's inland plains, forming the border between the states of New South Wales and Victoria as it flows into South Australia. From an east–west direction it turns south at Morgan for its final , reaching the eastern edge of Lake Alexandrina, which fluctuates in salinity. The water then flows throu ...

South Para Reservoir
South Para Reservoir is the second largest reservoir in South Australia, behind Mount Bold Reservoir, and the principal reservoir of the South Para River system. The reservoir's large capacity of around 45,330 megalitres and its location in the catchment area mean that it only ever fills completely once in every five years. Costing A$6.4 million, the reservoir took almost a decade to construct, between 1949 and 1958, due to a demand on resources in the post-war boom. The building of the historic Mannum–Adelaide pipeline from the River Murray to the water-short city of Adelaide was a key delay in South Para's construction; that pipeline today disperses water into the reservoir. The Reservoir is surrounded by nature reserve and has been a focus for two major revegetation projects, the first in the late 1950s when over 5000 trees and shrubs were planted, and the second as part of the South Australian Government's "Million Trees" initiative. In 1979 the mutilated body of 17-yea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Para River
The South Para River is a river located in the Mount Lofty Ranges northeast of Adelaide in the Australian state of South Australia. The river's name is based directly on the Kaurna word ''pari'' which means river. The "south" descriptor distinguishes it from the North Para River with which it merges. Course and features The South Para River rises in the Mount Lofty Ranges near Mount Crawford and Kersbrook and flows northwest through the Mount Lofty Ranges, passing through the Warren Reservoir and the South Para Reservoir, before reaching its confluence with the North Para River in Gawler to form the Gawler River. The South Para River descends over its course. The South Para River catchment is one of the key watersheds in the northern Mount Lofty Ranges. It plays an important role in the functioning of South Australia, providing much of the water used by Adelaide's domestic supply in the Northern Adelaide area. The rainfall in the South Para River catchment varies from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
