Troy Creek, Dubbo
Troy Creek catchment is a small area of land to the north-east of the city of Dubbo (pop 38,000), central western New South Wales, Australia. The catchment is noted for its significant record levels of past salinity. An ephemeral stream originating from the remnant vegetation Beni forest to the east flowing approximately 10 kilometres via Troy Gully north-west through grazing land, heavy residential, industrial and terminating into the Macquarie River system. History Various land uses such as significant clearing of the catchment has resulted in significant salinity, an issue where it soil and water table below becomes salt laden. Troy Creek has suffered significant scalding and vegetation loss as a direct result of salinity. Sections within the catchment have recorded soil salt levels twice that of sea water and over ten times tolerable to native grass and tree species. Local land care volunteers, businesses, and school students have planted thousands of trees in Troy Gully ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

New South Wales
New South Wales (commonly abbreviated as NSW) is a States and territories of Australia, state on the Eastern states of Australia, east coast of :Australia. It borders Queensland to the north, Victoria (state), Victoria to the south, and South Australia to the west. Its coast borders the Coral Sea, Coral and Tasman Seas to the east. The Australian Capital Territory and Jervis Bay Territory are Enclave and exclave, enclaves within the state. New South Wales' state capital is Sydney, which is also Australia's most populous city. , the population of New South Wales was over 8.3 million, making it Australia's most populous state. Almost two-thirds of the state's population, 5.3 million, live in the Greater Sydney area. The Colony of New South Wales was founded as a British penal colony in 1788. It originally comprised more than half of the Australian mainland with its Western Australia border, western boundary set at 129th meridian east in 1825. The colony then also includ ...

Salinity
Salinity () is the saltiness or amount of salt (chemistry), salt dissolved in a body of water, called saline water (see also soil salinity). It is usually measured in g/L or g/kg (grams of salt per liter/kilogram of water; the latter is dimensionless and equal to per mille, ‰). Salinity is an important factor in determining many aspects of the chemistry of natural waters and of biological processes within it, and is a state function, thermodynamic state variable that, along with temperature and pressure, governs physical characteristics like the density and heat capacity of the water. A contour line of constant salinity is called an ''isohaline'', or sometimes ''isohale''. Definitions Salinity in rivers, lakes, and the ocean is conceptually simple, but technically challenging to define and measure precisely. Conceptually the salinity is the quantity of dissolved salt content of the water. Salts are compounds like sodium chloride, magnesium sulfate, potassium nitrate, and sod ...

Ephemeral
Ephemerality (from the Greek word , meaning 'lasting only one day') is the concept of things being transitory, existing only briefly. Academically, the term ephemeral constitutionally describes a diverse assortment of things and experiences, from digital media to types of streams. "There is no single definition of ephemerality". With respect to unique performances, for example, it has been noted that " hemerality is a quality caused by the ebb and flow of the crowd's concentration on the performance and a reflection of the nostalgic character of specific performances". Because different people may value the passage of time differently, ephemerality may be a relative, perceptual concept: "In brief, what is short-lived may not be the object itself, but the attention we afford it".Ronald Beiner, ''Political Philosophy: What It Is and Why It Matters'' (2014), p. 10. Ephemerality and nature Geographical features An ephemeral stream is that which only exists following precipitation. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macquarie River (New South Wales)
The Macquarie River or Wambuul is part of the Macquarie– Barwon catchment within the Murray–Darling basin, is one of the main inland rivers in New South Wales, Australia. The river rises in the central highlands of New South Wales near the town of Oberon and travels generally northwest past the towns of Bathurst, Wellington, Dubbo, Narromine, and Warren to the Macquarie Marshes. The Macquarie Marshes then drain into the Darling River via the lower Barwon River. Lake Burrendong is a large reservoir with capacity of located near Wellington which impounds the waters of the Wambuul Macquarie River and its tributaries the Cudgegong River and the Turon River for flood control and irrigation. Name The Wiradjuri are the people of the three rivers, Wambuul, Kalare ( Lachlan) and the Murrumbidjeri ( Murrumbidgee). Wambuul means winding river, and included the tributary Fish River. It has also been spelt Wambool. The river was first documented for the British crown near Bathu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ground Water
Groundwater is the water present beneath Earth's surface in rock and soil pore spaces and in the fractures of rock formations. About 30 percent of all readily available fresh water in the world is groundwater. A unit of rock or an unconsolidated deposit is called an ''aquifer'' when it can yield a usable quantity of water. The depth at which soil pore spaces or fractures and voids in rock become completely saturated with water is called the ''water table''. Groundwater is recharged from the surface; it may discharge from the surface naturally at springs and seeps, and can form oases or wetlands. Groundwater is also often withdrawn for agricultural, municipal, and industrial use by constructing and operating extraction wells. The study of the distribution and movement of groundwater is ''hydrogeology'', also called groundwater hydrology. Typically, groundwater is thought of as water flowing through shallow aquifers, but, in the technical sense, it can also contain soil mois ...

Rivers Of New South Wales
This page discusses the rivers and hydrography of the state of New South Wales, Australia. The principal topographic feature of New South Wales is the series of low highlands and plateaus called the Great Dividing Range, which extend from north to south roughly parallel to the coast of the Coral and Tasman seas of the South Pacific Ocean. The two main categories of rivers in New South Wales, are those that rise in the Great Dividing Range and flow eastwards to the sea, the Coastal NSW Rivers; and those that rise on the other side of the crest of the range and flow westward, the Inland NSW Rivers. Most of the inland rivers eventually combine into the Murray-Darling network of rivers, which drains to the sea in South Australia. Major rivers The following rivers are the longest river systems, by length. Coastal rivers Due to the relatively close proximity of the Great Dividing Range to the eastern coast of New South Wales, in general, the coastal rivers are short, navigabl ...
