Styx River (Tasmania)
The Styx River is a perennial river in the centre of southern Tasmania, Australia. The upper reaches of the Styx River are in the Tasmanian Wilderness, south west of Maydena. The river is a popular destination for river-rafting and canoeing. Location and features The Styx River rises below Mount Mueller at an elevation of above sea level and flows generally east by north, joined by five minor tributaries, before reaching its confluence with the River Derwent near Macquarie Plains, west of . The river descends over its course. The Styx Valley contains old growth forests including the tallest hardwood trees on earth, ''Eucalyptus regnans''. The Wilderness Society and Senator Bob Brown have campaigned to save the forest from harvesting for sawn timber and woodchips. Some trees are so large they have become tourist attractions and named, including the ''Christmas Tree'' and ''Chapel Tree''. The first settlers in the Styx Valley arrived in 1812. The name has no classical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Styx Valley
The Styx Valley is a valley located adjacent to the Tasmanian Wilderness World Heritage Site on the island of Tasmania, Australia. The Styx River is the main drainage system of the valley that lies about northwest of Hobart, with the nearest town being Maydena. Location and features Temperate wet eucalypt forests in the region are home to the world's tallest flowering plants, ''Eucalyptus regnans''. Rainforest gullies are carpeted in mosses and lichens and shaded by the tree ferns ''Dicksonia antarctica'', known locally as Man-ferns, and other rainforest tree species including Southern Sassafras (''Atherosperma moschatum''), Myrtle Beech (''Nothofagus cunninghamii'') and Celery-top pine (''Phyllocladus aspleniifolius''). In 2002, Australia's most massive tree, nicknamed El Grande, was discovered. It died in an autumn burn in 2003. The valley has been the site of an ongoing conflict between environmentalists, who have proposed the protection of the site as a national pa ...

Confluence
In geography, a confluence (also: ''conflux'') occurs where two or more flowing bodies of water join to form a single channel. A confluence can occur in several configurations: at the point where a tributary joins a larger river (main stem); or where two streams meet to become the source of a river of a new name (such as the confluence of the Monongahela and Allegheny rivers at Pittsburgh, forming the Ohio); or where two separated channels of a river (forming a river island) rejoin at the downstream end. Scientific study of confluences Confluences are studied in a variety of sciences. Hydrology studies the characteristic flow patterns of confluences and how they give rise to patterns of erosion, bars, and scour pools. The water flows and their consequences are often studied with mathematical models. Confluences are relevant to the distribution of living organisms (i.e., ecology) as well; "the general pattern ownstream of confluencesof increasing stream flow and decreasing s ...

Rivers Of Tasmania
This page discusses the rivers and hydrography of the state of Tasmania, Australia. In the geography of Tasmania, the state is covered with a network of rivers and lake systems. As an island, all rivers eventually empty into the waters that surround Tasmania. There are four main river systems: #In the south, the Derwent flows from the Central Highlands past Hobart, to the sea at Storm Bay; #In the west, the Gordon River takes the waters of Lake Gordon and Lake Pedder and is joined by the Franklin River before flowing into Macquarie Harbour; #Flowing eastwards and to the south, the Huon River has its headwaters at Scotts Peak Dam on Lake Pedder, and reaches the sea in D'Entrecasteaux Channel; and #Flowing from the north-east, the South Esk, the state's longest river, joins the North Esk at Launceston to create the Tamar. Compared to the rest of Australia, Tasmania has a very high proportion of wild or undisturbed rivers. Catchment areas Major catchments of Tasmania are li ...

List Of Rivers Of Australia
This is a list of rivers of Australia. Rivers are ordered alphabetically, by state. The same river may be found in more than one state as many rivers cross state borders. Longest rivers nationally Longest river by state or territory Although the Murray River forms much of the border separating New South Wales and Victoria, it is not Victoria's longest river because the New South Wales border is delineated by the river's southern bank rather than by the middle of the river. The only section of the river formally within Victoria is a stretch of approximately where it separates Victoria and South Australia. At this point, the middle of the river forms the border. Rivers by state or territory The following is a list of rivers located within States and territories of Australia, Australian states and territories. Where a river crosses a state or territory boundary, it is listed in both states and territories. Where a river has a name that includes the word Stream, creek, it has ...

Woodchips
Woodchips are small- to medium-sized pieces of wood formed by cutting or chipping larger pieces of wood such as trees, branches, logging residues, stumps, roots, and wood waste. Woodchips may be used as a biomass solid fuel and are raw material for producing wood pulp. They may also be used as an organic mulch in gardening, landscaping, and ecosystem restoration; in bioreactors for denitrification; and as a substrate for mushroom cultivation. The process of making woodchips is called wood chipping and is done using a wood chipper. The types of woodchips formed following chipping is dependent on the type of wood chipper used and the material from which they are made. Woodchip varieties include: forest chips (from forested areas), wood residue chips (from untreated wood residues, recycled wood and off-cuts), sawing residue chips (from sawmill residues), and short rotation forestry chips (from energy crops). Raw materials The raw materials of woodchips can be pulpwood, waste wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bob Brown
Robert James Brown (born 27 December 1944) is a former Australian politician, medical doctor and environmentalist. He was a senator and the parliamentary leader of the Australian Greens. Brown was elected to the Australian Senate on the Tasmanian Greens ticket, joining with sitting Greens Western Australia senator Dee Margetts to form the first group of Australian Greens senators following the 1996 federal election. He was re-elected in 2001 and in 2007. He was the first openly gay member of the Parliament of Australia and the first openly gay leader of an Australian political party. While serving in the Tasmanian parliament, Brown successfully campaigned for a large increase in the protected wilderness areas. Brown led the Australian Greens from the party's foundation in 1992 until April 2012, a period in which polls grew to around 10% at state and federal levels (13.1% of the primary vote in 2010). From 2002 to 2004, when minor parties held the balance of power in the Sen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eucalyptus Regnans
''Eucalyptus'' () is a genus of over seven hundred species of flowering trees, shrubs or mallees in the myrtle family, Myrtaceae. Along with several other genera in the tribe Eucalypteae, including ''Corymbia'', they are commonly known as eucalypts. Plants in the genus ''Eucalyptus'' have bark that is either smooth, fibrous, hard or stringy, leaves with oil glands, and sepals and petals that are fused to form a "cap" or operculum over the stamens. The fruit is a woody capsule commonly referred to as a "gumnut". Most species of ''Eucalyptus'' are native to Australia, and every state and territory has representative species. About three-quarters of Australian forests are eucalypt forests. Wildfire is a feature of the Australian landscape and many eucalypt species are adapted to fire, and resprout after fire or have seeds which survive fire. A few species are native to islands north of Australia and a smaller number are only found outside the continent. Eucalypts have been grown ...

Navigation
Navigation is a field of study that focuses on the process of monitoring and controlling the movement of a craft or vehicle from one place to another.Bowditch, 2003:799. The field of navigation includes four general categories: land navigation, marine navigation, aeronautic navigation, and space navigation. It is also the term of art used for the specialized knowledge used by navigators to perform navigation tasks. All navigational techniques involve locating the navigator's position compared to known locations or patterns. Navigation, in a broader sense, can refer to any skill or study that involves the determination of position and direction. In this sense, navigation includes orienteering and pedestrian navigation. History In the European medieval period, navigation was considered part of the set of '' seven mechanical arts'', none of which were used for long voyages across open ocean. Polynesian navigation is probably the earliest form of open-ocean navigation; it was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australian Height Datum
The Australian Height Datum was introduced in 1971 as the official vertical datum for Australia, and thereby serves as the benchmark to which all height measurements are referred. The Australian Height Datum is an amalgamation of decades of spirit levelling work conducted by numerous state and territory authorities across the country, and was corrected to align with the mean sea level observations of thirty tide gauges positioned around the entire coastline. While it remains the published vertical datum for all surveying and engineering operations performed throughout Australia, newer technologies have uncovered numerous deficiencies, offsets and distortions within the Australian Height Datum, leading to discussions about defining a new Australian vertical datum. Background The National Mapping Council (pre-1945) Prior to the creation of the Australian Height Datum, levelling surveys were carried out by professional surveyors for construction and mapping purposes using only ...

Mouth (river)
A river mouth is where a river flows into a larger body of water, such as another river, a lake/reservoir, a bay/gulf, a sea, or an ocean. At the river mouth, sediments are often deposited due to the slowing of the current reducing the carrying capacity of the water. The water from a river can enter the receiving body in a variety of different ways. The motion of a river is influenced by the relative density of the river compared to the receiving water, the rotation of the earth, and any ambient motion in the receiving water, such as tides or seiches. If the river water has a higher density than the surface of the receiving water, the river water will plunge below the surface. The river water will then either form an underflow or an interflow within the lake. However, if the river water is lighter than the receiving water, as is typically the case when fresh river water flows into the sea, the river water will float along the surface of the receiving water as an overflow.
