Manilla River
Manilla River, a perennial stream that is part of the Namoi catchment within the Murray–Darling basin, is located in the Northern Tablelands district of New South Wales, Australia. The stream (called a river) rises south–west of Barraba on the northern slopes of the Baldwins Range and drains a portion of the hill country on the western side of the New England highlands and the southern slopes of the Nandewar Range; flowing generally north and east and to the town of Barraba. During its course, the stream is joined by five minor tributaries, and flows in a southerly direction towards its confluence with the Namoi River at the town of Manilla; dropping over its length of . The name of the river is derived from the Australian Aboriginal words of ''manilla'', ''maneela'', or ''muneela'' meaning "winding river" or "round about". Approximately north of Manilla, Split Rock Reservoir, on the Manilla River, provides one of the main water storages for flood control and irrigati ...

Australian Aboriginal Languages
The Indigenous languages of Australia number in the hundreds, the precise number being quite uncertain, although there is a range of estimates from a minimum of around 250 (using the technical definition of 'language' as non-mutually intelligible varieties) up to possibly 363. The Indigenous languages of Australia comprise numerous language families and isolates, perhaps as many as 13, spoken by the Indigenous peoples of mainland Australia and a few nearby islands. The relationships between the language families are not clear at present although there are proposals to link some into larger groupings. Despite this uncertainty, the Indigenous Australian languages are collectively covered by the technical term "Australian languages", or the "Australian family". The term can include both Tasmanian languages and the Western Torres Strait language, but the genetic relationship to the mainland Australian languages of the former is unknown, while the latter is Pama–Nyungan, th ...

Reservoir
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 ...

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, naviga ...

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 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 creek, it has been officially designated as a river.

Flood Control
Flood control methods are used to reduce or prevent the detrimental effects of flood waters."Flood Control", MSN Encarta, 2008 (see below: Further reading). Flood relief methods are used to reduce the effects of flood waters or high water levels. Flooding can be caused by a mix of both natural processes, such as extreme weather upstream, and human changes to waterbodies and runoff. Though building hard infrastructure to prevent flooding, such as flood walls, can be effective at managing flooding, increased best practice within landscape engineering is to rely more on soft infrastructure and natural systems, such as marshes and flood plains, for handling the increase in water. For flooding on coasts, coastal management practices have to not only handle changes water flow, but also natural processes like tides. Flood control and relief is a particularly important part of climate change adaptation and climate resilience, both sea level rise and changes in the weather ...

Tributary
A tributary, or affluent, is a stream or river that flows into a larger stream or main stem (or parent) river or a lake. A tributary does not flow directly into a sea or ocean. Tributaries and the main stem river drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean. The Irtysh is a chief tributary of the Ob river and is also the longest tributary river in the world with a length of . The Madeira River is the largest tributary river by volume in the world with an average discharge of . A confluence, where two or more bodies of water meet, usually refers to the joining of tributaries. The opposite to a tributary is a distributary, a river or stream that branches off from and flows away from the main stream. PhysicalGeography.net, Michael Pidwirny ...

Watercourse
A stream is a continuous body of surface water flowing within the bed and banks of a channel. Depending on its location or certain characteristics, a stream may be referred to by a variety of local or regional names. Long large streams are usually called rivers, while smaller, less voluminous and more intermittent streams are known as streamlets, brooks or creeks. The flow of a stream is controlled by three inputs – surface runoff (from precipitation or meltwater), daylighted subterranean water, and surfaced groundwater ( spring water). The surface and subterranean water are highly variable between periods of rainfall. Groundwater, on the other hand, has a relatively constant input and is controlled more by long-term patterns of precipitation. The stream encompasses surface, subsurface and groundwater fluxes that respond to geological, geomorphological, hydrological and biotic controls. Streams are important as conduits in the water cycle, instruments in groundwa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nandewar Range
The Nandewar Range, a mountain range that is part of the Great Dividing Range, is located in the North West Slopes region of New South Wales, Australia. The range is situated approximately east of the township of Narrabri. John Oxley was the first European to see the range in 1818 as he explored the New South Wales. Location and features The range is located on the western, inland, side of the New England region, and generally forms the watershed divide between the Namoi River and Gwydir River catchment basins to the south and north respectively. The Macdonald River starting south of Walcha drains west to Warrabah National Park where it changes its name to the Namoi then is added to by the Manilla River, Peel River and Mooki River. The Horton River runs north to the Gwydir. Both rivers together drain segments of the Nandewar Range. The eastern part of the Nandewar Range starts at the Great Dividing Range south of Uralla. The main road between Barraba and Bingara ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baldwins Range
Richard Thomas and Baldwins Ltd (RTB) was a major iron, steel and tinplate producer, primarily based in Wales and formed in 1948 by the merger of Richard Thomas & Co Ltd with Baldwins Ltd. It was absorbed into British Steel Corporation in 1967. The business now forms part of Corus, a subsidiary of Tata Steel. Richard Thomas & Co Richard Thomas & Co Ltd was an iron, steel and tinplate producer and colliery proprietor. The founder, Richard Thomas (died 1916), leased two tinplate works in Gloucestershire: Lydbrook in 1871 and Lydney in 1876. He went on to acquire local collieries and, in 1888, the Melingriffith Tin Plate Works near Cardiff. Richard Thomas & Co, in which Thomas was succeeded as managing director by his son, Richard Beaumont Thomas, in 1888, became one of the principal tinplate manufacturers in the UK. The Ebbw Vale Steel Iron and Coal Company was taken over by Richard Thomas & Co in 1936, and a new steel plant and strip mill was erected in the town. Baldwins ...

Perennial Stream
A perennial stream is a stream that has continuous flow of surface water throughout the year in at least parts of its catchment during seasons of normal rainfall, Water Supply Paper 494. as opposed to intermittent river, one whose flow is intermittent. In the absence of irregular, prolonged or extreme drought, a perennial stream is a watercourse, or segment, element or emerging body of water which continually delivers groundwater. For example, an damming, artificial disruption of stream, variability in flow or stream selection associated with the activity in hydropower installations, do not affect this status. Perennial streams do not include stagnant water (stream pool, pools and puddle, waterholes), reservoirs, oxbow lake, cutoff lakes and ponds that persist throughout the year. All other streams, or parts of them, should be considered seasonal rivers or lakes. The stream can cycle from intermittent to perpetual through multiple iterations.

Split Rock Dam
Split Rock Dam is a minor ungated concrete faced rock fill embankment dam with concrete chute spillway across the Manilla River upstream of Manilla in the north-western slopes region of New South Wales, Australia. The dam's purpose includes flood mitigation, irrigation, water supply and conservation. The impounded reservoir is called Split Rock Reservoir. Location and features Commenced in 1984, completed in 1987, and upgraded in 2012, the Split Rock Dam is a minor dam on the Manilla River, located approximately upstream, north of Manilla and north of Tamworth, accessed by a turnoff from Fossickers Way. The dam was built by Abignano Pty Limited on behalf of the New South Wales Department of Land and Water Conservation to supply water for irrigation, flood mitigation and potable water for towns in the Namoi Valley, including Manilla and Barraba. Together with Keepit Dam, Split Rock Dam supplies extensive irrigation water in the Namoi Valley. The dams also supply water ...

Murray–Darling Basin
The Murray–Darling basin is a large geographical area in the interior of southeastern Australia, encompassing the drainage basin of the tributaries of the Murray River, Australia's longest river, and the Darling River, a right tributary of the Murray and Australia's third-longest river. The basin, which includes six of Australia's seven longest rivers and covers around one-seventh of the Australian landmass, is one of the country's most significant agricultural areas providing one-third of Australia's food supply. Located west of the Great Dividing Range, it drains southwestly into the Great Australian Bight and spans most of the states of New South Wales and Victoria, the Australian Capital Territory, and parts of the states of Queensland (the lower third) and South Australia (the southeastern corner). The basin is in length, with the Murray River being long. Most of the basin is flat, low-lying and far inland, and receives little direct rainfall. The many river ...
