Molonglo River
The Molonglo River, a perennial river that is part of the Murrumbidgee 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. Location and features The river rises on the western side of the Great Dividing Range, in Tallaganda State Forest at and flows generally from south to north before turning northwest, through Carwoola and the outskirts of Queanbeyan, where it has confluence with its major tributary, the Queanbeyan River, and then continues through Canberra, where it has been dammed by the Scrivener Dam to form Lake Burley Griffin. The river then flows to its mouth with the Murrumbidgee River, near Uriarra Crossing. Over its course the Molonglo River alternates between long broad floodplains and narrow rocky gorges several times. One of these floodplains is called the Molonglo Plain. From source to mouth, the river is traversed by the Captains Flat Road at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Murrumbidgee River
The Murrumbidgee River () is a major tributary of the Murray River within the Murray–Darling basin and the second longest river in Australia. It flows through the Australian state of New South Wales and the Australian Capital Territory, descending over , generally in a west-northwesterly direction from the foot of Peppercorn Hill in the Fiery Range of the Snowy Mountains towards its confluence with the Murray River near Boundary Bend. The word ''Murrumbidgee'' or ''Marrmabidya'' means "big water" in the Wiradjuri language, one of the local Australian Aboriginal languages. The river itself flows through several traditional Aboriginal Australian lands, home to various Aboriginal peoples. In the Australian Capital Territory, the river is bordered by a narrow strip of land on each side; these are managed as the Murrumbidgee River Corridor (MRC). This land includes many nature reserves, eight recreation reserves, a European heritage conservation zone and rural leases. Flow The ...

River Mouth
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.

Lake Burley Griffin
Lake Burley Griffin is an artificial lake in the centre of Canberra, the capital of Australia. It was completed in 1963 after the Molonglo River, which ran between the city centre and Parliamentary Triangle, was dammed. It is named after Walter Burley Griffin, the American architect who won the competition to design the city of Canberra. Griffin designed the lake with many geometric motifs, so that the axes of his design lined up with natural geographical landmarks in the area. However, government authorities changed his original plans, and no substantial work was completed before he left Australia in 1920. Griffin's proposal was further delayed by the Great Depression and World War II, and it was not until the 1950s that planning resumed. After political disputes and consideration of other proposed variations, excavation work began in 1960 with the energetic backing of Australian Prime Minister Robert Menzies. After the completion of the bridges and dams, the dams were locked ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scrivener Dam
Scrivener Dam is a concrete gravity dam that impounds the Molonglo River in Canberra, Australian Capital Territory.

Named in honour of surveyor Charles Scrivener, the dam was officially inaugurated on and the official filling of the lake commemorated on by the Prime Minister, Robert Menzies. The dam wall is located on Lady Denman Drive and is adjacent to the National Zoo & Aquarium and a viewing area for the official residence of the Governor-General of Australia. Technical details Scrivener Dam, designed in Germany, holds back the waters of the Molonglo River within Lake Burley Griffin. About of concrete was used in the construction of the dam wall. The dam is high and long with a maximum wall thickness of . The dam is designed to handle a once in 5,000 year flood event. It utilised state-of-the-art post-tensioning techniques to cope with any problems or movements in the r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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 & S ...

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.

Nature Reserve
A nature reserve (also known as a wildlife refuge, wildlife sanctuary, biosphere reserve or bioreserve, natural or nature preserve, or nature conservation area) is a protected area of importance for flora, fauna, or features of geological or other special interest, which is reserved and managed for purposes of conservation and to provide special opportunities for study or research. They may be designated by government institutions in some countries, or by private landowners, such as charities and research institutions. Nature reserves fall into different IUCN categories depending on the level of protection afforded by local laws. Normally it is more strictly protected than a nature park. Various jurisdictions may use other terminology, such as ecological protection area or private protected area in legislation and in official titles of the reserves. History Cultural practices that roughly equate to the establishment and maintenance of reserved areas for animals date bac ...
