Trevallyn Dam
The Trevallyn Dam is a dam on the South Esk River in Launceston, Tasmania, Australia and is used to provide water for hydroelectricity. The dam was completed in 1955 as part of the Trevallyn Hydro Electric Scheme and now holds the waters of Lake Trevallyn. Specifications Lake Trevallyn is a concrete gravity dam built on Dolerite bedrock. The spillway height is 26.8 metres and the dam wall is 177 metres long. The lake has a surface area of and storage capacity of . ANCOLD lists Trevallyn Dam as having a dam wall height of 33 metres and the total volume of the wall as . The dam diverts water to the Trevallyn Power Station through a 3.2 km tunnel. Lake Trevallyn Lake Trevallyn is the long, narrow lake created by the dam and extends as far as Hadspen where the first rapids begin at the junction of the Meander and South Esk Rivers. The widest point on the lake is at Stephenson's Bay where it reaches 390 m wide. Launceston's outer suburb of Blackstone Heights and pa ...

Anabaena Circinalis
''Anabaena circinalis'' is a species of Gram-negative, photosynthetic cyanobacteria common to freshwater environments throughout the world. Much of the scientific interest in '' A. circinalis '' owes to its production of several potentially harmful cyanotoxins, ranging in potency from irritating to lethal. Under favorable conditions for growth, '' A. circinalis '' forms large algae-like blooms, potentially harming the flora and fauna of an area. Morphology ''Anabaena circinalis'' exhibits a filamentous morphology, each filament a string of task-specific cells. The appearance of cell differentiation was a great evolutionary leap; marking cyanobacteria as one of the first multicellular organisms on Earth. On the '' A. circinalis '' filament, the most numerous structures are vegetative cells, responsible for the photosynthesis of high-energy sugars from environmental carbon, water, and sunlight. The energy from photosynthesis is used, in part, for the biosynthesis of cellular m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dams Completed In 1955
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 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. Ancient dams were built in Mesopotamia and the Middle East for water control. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. Egyptians also built dams, ...

Buildings And Structures In Launceston, Tasmania
A building or edifice is an enclosed structure with a roof, walls and windows, usually standing permanently in one place, such as a house or factory. Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for numerous factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the concept, see ''Nonbuilding structure'' for contrast. Buildings serve several societal needs – occupancy, primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical separation of the human habitat (a place of comfort and safety) from the ''outside'' (a place that may be harsh and harmful at times). buildings have been objects or canvasses of much artistic expression. In recent years, interest in sustainable planning and building practi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Queen Victoria Museum And Art Gallery
The Queen Victoria Museum & Art Gallery (QVMAG) is a museum located in Launceston, Tasmania, Australia. It is the largest museum in Australia not located in a capital city. History The foundation stone for the original building to house the Queen Victoria Museum & Art Gallery was laid by the Mayor of Launceston, Robert Carter, on 21 June 1887. Alexander Morton, of the museum in Hobart, acted as honorary curator from its opening in 1891 until 1896, with Herbert Hedley Scott assuming the role of curator in May 1897. In 1926 the Launceston City Council amended the name to Queen Victoria Museum and Art Gallery to avoid confusion with the state of Victoria. Scott died in 1938 and was succeeded as director by his son, Eric Oswald Gale Scott later that year. Collection and locations Established in 1891, the Queen Victoria Museum & Art Gallery has a strong reputation for its collection which includes fine exhibitions of colonial art, contemporary craft and design, Tasmanian histo ...

Craspedacusta Sowerbyi
''Craspedacusta sowerbii'' or peach blossom jellyfish is a species of freshwater hydrozoan jellyfish, or hydromedusa cnidarian. Hydromedusan jellyfish differ from scyphozoan jellyfish because they have a muscular, shelf-like structure called a velum on the ventral surface, attached to the bell margin. Originally from the Yangtze basin in China, ''C. sowerbii'' is an introduced species now found throughout the world in bodies of fresh water. Form ''C. sowerbii'' medusae are about 20–25 mm (approximately 1 in.) in diameter, somewhat flatter than a hemisphere, and very delicate, when fully grown. They have a whorl of up to 400 tentacles tightly packed around the bell margin. Hanging down from the center of the inside of the bell is a large stomach structure called a manubrium, with a mouth-opening with four frilly lips. Circulation of nutrients is facilitated by four radial canals which originate at the edges of the stomach (manubrium), and which are also connected to a rin ...

Eucalypt
Eucalypt is any woody plant with Capsule (fruit), capsule fruiting bodies belonging to one of seven closely related genera (of the tribe Eucalypteae) found across Australia: ''Eucalyptus'', ''Corymbia'', ''Angophora'', ''Stockwellia'', ''Allosyncarpia'', ''Eucalyptopsis'' and ''Arillastrum''. In Australia, they are commonly known as gum trees or stringybarks. Taxonomy For an example of changing historical perspectives, in 1991, largely genetic evidence indicated that some prominent ''Eucalyptus'' species were actually more closely related to ''Angophora'' than to other eucalypts; they were accordingly split off into the new genus ''Corymbia''. Although separate, all of these genera and their species are allied and it remains the standard to refer to the members of all seven genera ''Angophora'', ''Corymbia'', ''Eucalyptus'', ''Stockwellia'', ''Allosyncarpia'', ''Eucalyptopsis'' and ''Arillastrum'' as "eucalypts" or as the eucalypt group.

South Esk River
The South Esk River, the longest river in Tasmania, is a major perennial river located in the northern region of Tasmania, Australia. Location and features The South Esk springs from the eastern foothills of the Ben Lomond plateau near Mathinna and the river's course describes an arc around the entire southern promontory of the mountain – running through Fingal, Avoca and Evandale before winding its way northwest through Perth, Longford and Hadspen. The river merges with the tributary Meander River, then flows through the narrows of the Cataract Gorge to finally meet the North Esk River at Launceston. From this confluence arises kanamaluka/Tamar River, which runs to the Bass Strait. The natural river flow is interrupted by the Trevallyn Dam, near Launceston, constructed as part of the Trevallyn Power Station hydroelectric power scheme. The river is subject to flooding which overflows at Lake Trevallyn to create the spectacle of high rapids coursing through the n ...
