Queanbeyan River
The Queanbeyan River, a perennial stream that is part of the Molonglo catchment within the Murray–Darling basin, is located in the Monaro and Capital Country regions of New South Wales and the Australian Capital Territory, in Australia. The river is in length with a catchment area of . The Queanbeyan River and the Cotter River meet the potable water supply needs of the Canberra and Queanbeyan region and whose water quality is specifically protected under Federal legislation. It is believed that the local Aboriginal Ngarigo people used a word that sounded like ''queanbeyan'' to describe the river, said to mean "clearwater". River course The headwaters of the Queanbeyan River rise east-southeast of Queanbeyan and about northeast of the township of Bredbo, near the village of Jerangle. Fourteen tributaries upstream of the Googong Dam contribute to the river flow including the Burra, Urialla, Tinderry, Ballinafad, Groggy, Woolpack, Sherlock, Lyons, Towneys and Mile Creeks. Th ...

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, thoug ...

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 ...

Canberra
Canberra ( ) is the capital city of Australia. Founded following the federation of the colonies of Australia as the seat of government for the new nation, it is Australia's largest inland city and the eighth-largest city overall. The city is located at the northern end of the Australian Capital Territory at the northern tip of the Australian Alps, the country's highest mountain range. As of June 2021, Canberra's estimated population was 453,558. The area chosen for the capital had been inhabited by Indigenous Australians for up to 21,000 years, with the principal group being the Ngunnawal people. European settlement commenced in the first half of the 19th century, as evidenced by surviving landmarks such as St John's Anglican Church and Blundells Cottage. On 1 January 1901, federation of the colonies of Australia was achieved. Following a long dispute over whether Sydney or Melbourne should be the national capital, a compromise was reached: the new capital would be buil ...

Water Supply
Water supply is the provision of water by public utilities, commercial organisations, community endeavors or by individuals, usually via a system of pumps and pipes. Public water supply systems are crucial to properly functioning societies. These systems are what supply drinking water to populations around the globe. Aspects of service quality include continuity of supply, water quality and water pressure. The institutional responsibility for water supply is arranged differently in different countries and regions (urban versus rural). It usually includes issues surrounding policy and regulation, service provision and standardization. The cost of supplying water consists, to a very large extent, of fixed costs (capital costs and personnel costs) and only to a small extent of variable costs that depend on the amount of water consumed (mainly energy and chemicals). Almost all service providers in the world charge tariffs to recover part of their costs. Water supply is a separate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potable Water
Drinking water is water that is used in drink or food preparation; potable water is water that is safe to be used as drinking water. The amount of drinking water required to maintain good health varies, and depends on physical activity level, age, health-related issues, and environmental conditions. This 2004 article focuses on the USA context and uses data collected from the US military. Recent work showed that the most important driver of water turnover which is closely linked to water requirements is energy expenditure. For those who work in a hot climate, up to a day may be required. Typically in developed countries, tap water meets drinking water quality standards, even though only a small proportion is actually consumed or used in food preparation. Other typical uses for tap water include washing, toilets, and irrigation. Greywater may also be used for toilets or irrigation. Its use for irrigation however may be associated with risks. Water may also be unacceptable due to l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cotter River
The Cotter River, a perennial river of the Murrumbidgee catchment within the Murray–Darling basin, is located in the Australian Capital Territory, Australia. The Cotter River, together with the Queanbeyan River, is one of two rivers that provides potable water to the Canberra and Queanbeyan region. Course The river rises on the eastern slopes of the Brindabella Ranges in the south-west of the Australian Capital Territory (ACT), within Namadgi National Park, and flows generally north, joined by six minor tributaries, including Paddys River, before reaching its confluence with the Murrumbidgee River, near Casuarina Sands, west of the suburb of Weston Creek. The river descends over its course. History The traditional custodians of the land surrounding the Cotter River are the Aboriginal people of the Ngunnawal clan. The river was named in honour of Garrett Cotter, an Irish-born convict who was transported to Australia for "the term of his natural life". Cotter was banishe ...

Drainage Basin
A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the '' drainage divide'', made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, "watershed" is used only in its original sense, that of a drainage divide. In a closed drainage basin, or endorheic basin, the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, a dry lake, or a point where surface water is lost underground. Drainage basins are similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 rivers it c ...

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.

Googong Dam
Googong Dam is a minor ungated earth and rock fill with clay core embankment dam with concrete chute spillway plus a nearby high earthfill saddle embankment across the Queanbeyan River upstream of Queanbeyan in the Capital Country region of New South Wales, Australia. The dam's purpose includes water supply for Canberra and Queanbeyan. The impounded reservoir is called Googong Reservoir. Googong Dam was created through enabling legislation enacted via the passage of the ''Canberra Water Supply (Goodong Dam) Act, 1974''. History A green ban was briefly imposed by the Builders Labourers Federation for a few days until adequate assurances that marine life in Lake Burley Griffin would not be harmed. Location and features Completed in 1979, the Googong Dam is a minor dam on the Queanbeyan River and Bradleys Creek and is located approximately south of the city of Queanbeyan on the lower reaches of the river. The dam was built by Thiess based on designs developed by the Commonwea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 A dam is a barrier that stops or restricts the flow of surface water or underground streams ...
