46-688: The Gordon Dam , also known as the Gordon River Dam , is a major gated double curvature concrete arch dam with a controlled spillway across the Gordon River , located in Southwest National Park , Tasmania, Australia. The impounded reservoir is called Lake Gordon . The dam was constructed in 1974 by the Hydro Electric Corporation (TAS) for the purpose of generating hydro-electric power via

92-545: A special interest group within Engineers Australia, runs a program that recognises historically significant engineering works. Such works have a plaque on display, with a brief summary of the significance of the work. The program was established in 1984 with two categories of awards, "National Engineering Landmark" and "Historic Engineering Marker". In 2009 these were renamed "Engineering Heritage National Landmark" and "Engineering Heritage Marker"; in 2011 and 2012

After 4 m (13 ft) was added to the dam in 1850, it became 64 m (210 ft) tall and remained the tallest dam in the world until the early 20th century. The Kurit Dam was of masonry design and built in a very narrow canyon. The canyon was so narrow that its crest length is only 44% of its height. The dam

276-577: A variety of Acts in ad hoc areas, many of which relate to engineers in the building and construction industry. There are also many pieces of subordinate legislation, such as regulations, by-laws and orders-in-council that impose various prescriptive standards and incur unnecessary costs to the engineering industry in complying. In Queensland, persons who are not registered with the Board of Professional Engineers Queensland are prohibited from offering or providing professional engineering services. The only exception

322-617: Is double-curved in both its horizontal and vertical planes may be called a dome dam . Arch dams with more than one contiguous arch or plane are described as multiple-arch dams . Early examples include the Roman Esparragalejo Dam with later examples such as the Daniel-Johnson Dam (1968) and Itaipu Dam (1982). However, as a result of the failure of the Gleno Dam shortly after it was constructed in 1923,

368-502: Is 214 meters (702 ft) high and 1,314 meters (4,311 ft) long across its crest. It was completed in 1968 and put in service in 1970. Pensacola Dam was one of the last multiple arch types built in the United States. Its NRHP application states that this was because three dams of this type failed: (1) Gem Lake Dam, St. Francis Dam (California), Lake Hodges Dam (California). None of these failures were inherently caused by

The NER is aimed at removing any current inconsistencies across State/Territory jurisdictions. The NER caters for nine (9) general and ten (10) special areas of practice aligned to demonstrated professional competence and experience. Registration on the 10 special areas of practice will be restricted to Chartered members of Engineers Australia and registrants who have successfully completed Engineers Australia's Chartered assessment process. Registrants on

If the person is not a member, then Engineers Australia has no authority to commence an investigation or take any action regarding the person's professional conduct. Engineers Australia is also not able to offer legal advice in relation to contractual or common law disputes or criminal matters and the complaints process will not result in financial restitution or compensation. One of Engineers Australia's core activities

1196-560: The Gordon River, despite the support of Tasmanian politicians such as Eric Reece , Robin Gray , and others to build the Franklin Dam further downstream. The construction of Gordon Dam resulted in some flooding of the connected Lake Pedder as planned. Subsequent opposition to restore Lake Pedder failed after a Parliamentary inquiry in 1995. The dam was designed with Dr. Sergio Guidici as the chief engineer. He went on to be involved with

The dam is connected with the Gordon River Power Station, 183 metres (600 ft) under the surface of the switch yard. In 2015, the Perth-based YouTube channel How Ridiculous broke the world record for the world's highest basketball shot at Gordon dam, though this record has since been surpassed by How Ridiculous themselves twice over. Due to an extreme drought in 2015 and

Gordon Dam is almost twice

1702-401: The multiple arch design. The design of an arch dam is a very complex process. It starts with an initial dam layout, that is continually improved until the design objectives are achieved within the design criteria.

The water level fell 45 metres to a record low of six per cent capacity. Pictures document the dramatic effect. After repair of Basslink and record rainfalls, Lake Gordon levels had recovered to -28 metres by January 2017. The dam is listed as a National Engineering Landmark by Engineers Australia as part of its Engineering Heritage Recognition Program . Arch dam In general, arch dams are classified based on

1932-614: The world, in particular by the U.S. Bureau of Reclamation . In 1920, the Swiss engineer and dam designer Alfred Stucky developed new calculation methods for arch dams, introducing the concept of elasticity during the construction of the Montsalvens arch dam in Switzerland, thereby improving the dam profile in the vertical direction by using a parabolic arch shape instead of a circular arch shape. Pensacola Dam , completed in

1978-629: Was built on the Salmon Creek near Juneau , Alaska . The Salmon Creek Dam's upstream face bulged upstream, which relieved pressure on the stronger, curved lower arches near the abutments. The dam also had a larger toe, which off-set pressure on the upstream heel of the dam, which now curved more downstream. The technology and economical benefits of the Salmon Creek Dam allowed for larger and taller dam designs. The dam was, therefore, revolutionary, and similar designs were soon adopted around

On 1 May 1926 the Institution was incorporated as a company limited by guarantee. Twelve years later, on 10 March 1938 His Majesty King George VI granted a charter of incorporation to the Institution, reconstituting it as a body corporate and politic by Royal Charter. The Institution of Engineers Australia
