Don River (Queensland)
The Don River is a river in North Queensland, Australia. Course and features The Don River rises in the Clarke Range, part of the Great Dividing Range, below Mount Roundhill and west of . The river flows generally north by northeast through the Eungella National Park and is joined by thirteen minor tributaries, towards its mouth and empties into the Coral Sea north of . With a catchment area of , the river descends over its course. High salinity levels have been recorded at the mouth of the river. Land use in the upper catchment is mostly beef cattle production with crops grown in the richer soils downstream. The river is crossed by the Bruce Highway via the Don River Bridge at Bowen. Flooding The highest recorded flood was in 1970 when the river reached at the Bowen Pumping Station. The river delta is particularly vulnerable to flooding during cyclones. Floods in 2008 left deposits of sand which raised the riverbed considerably. Approval to dredge sand was granted by t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Drainage Basin
A drainage basin is an area of land in which 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 the drainage divide line. A drainage basin's boundaries are determined by watershed delineation, a common task in environmental engineering and science. In a closed drainage basin, or endorheic basin, rather than flowing to the ocean, water converges toward the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sand Mining
Sand mining is the extraction of sand, mainly through an open pit (or sand pit) but sometimes mined from beaches and inland dunes or dredged from ocean and river beds. Sand is often used in manufacturing, for example as an abrasive or in concrete. It is also used on icy and snowy roads usually mixed with salt, to lower the melting point temperature, on the road surface. Sand can replace eroded coastline. Some uses require higher purity than others; for example sand used in concrete must be free of seashell fragments. Sand mining presents opportunities to extract rutile, ilmenite, and zircon, which contain the industrially useful elements titanium and zirconium. Besides these minerals, beach sand may also contain garnet, leucoxene, sillimanite, and monazite. These minerals are quite often found in ordinary sand deposits. A process known as elutriation is used, whereby flowing water separates the grains based on their size, shape, and density. Sand mining is a direct cause ...

Whitsunday Regional Council
The Whitsunday Region is a local government area located in North Queensland, Australia. Established in 2008, it was preceded by two previous local government areas with a history extending back to the establishment of regional local government in Queensland in 1879. It has an estimated operating budget of A$48.8m. In the , the Whitsunday Region had a population of 37,152 people. History Prior to 2008, the new Whitsunday Region was an entire area of two previous and distinct local government areas: * the Shire of Bowen; * and the Shire of Whitsunday. The Bowen Municipality was constituted on 7 August 1863 under the ''Municipalities Act 1858'' (a piece of New South Wales legislation inherited by Queensland at its separation four years earlier). On 11 November 1879, the Wangaratta Division was created as one of 74 divisions around Queensland under the ''Divisional Boards Act 1879''. With the passage of the ''Local Authorities Act 1902'', Wangaratta became a shire and Bowen b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Queensland Government is the state government of Queensland, Australia, a Parliament, parliamentary constitutional monarchy. Government is formed by the party or coalition that has gained a majority in the Queensland Legislative Assembly, state Legislative Assembly, with the governor officially appointmenting office-holders. The first government of Queensland was formed in 1859 when Queensland separated from New South Wales under the Constitution of Queensland, state constitution. Since Federation of Australia, federation in 1901, Queensland has been a States and territories of Australia, state of Australia, with the Constitution of Australia regulating its relationship with the Australian Government, federal government. Queensland's system of government is influenced by the Westminster system and Federalism in Australia, Australia's federal system of government. Executive acts are given legal force through the actions of the governor of Queensland (the representative of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

River Delta
A river delta is a landform, archetypically triangular, created by the deposition of the sediments that are carried by the waters of a river, where the river merges with a body of slow-moving water or with a body of stagnant water. The creation of a river delta occurs at the '' river mouth'', where the river merges into an ocean, a sea, or an estuary, into a lake, a reservoir, or (more rarely) into another river that cannot carry away the sediment supplied by the feeding river. Etymologically, the term ''river delta'' derives from the triangular shape (Δ) of the uppercase Greek letter delta. In hydrology, the dimensions of a river delta are determined by the balance between the watershed processes that supply sediment and the watershed processes that redistribute, sequester, and export the supplied sediment into the receiving basin. River deltas are important in human civilization, as they are major agricultural production centers and population centers. They can provide ...

Bruce Highway
The Bruce Highway is a major highway in Queensland, Australia. Commencing in the state capital, Brisbane, it passes through areas close to the eastern coast on its way to Cairns in Far North Queensland. The route is part of the Australian National Highway (Australia), National Highway and also part of Highway 1 (Australia), Highway 1, the longest highway route in Australia. Its length is approximately ; it is entirely sealed with bitumen. The highway is named after a popular former Queensland and federal politician, Henry Bruce (Australian politician), Harry Bruce. Bruce was the state Minister for Works in the mid-1930s when the highway was named after him. The highway once passed through Brisbane, but was truncated at Bald Hills, Queensland, Bald Hills when the Gateway Motorway became National Highway 1 upon its opening in December 1986. It was previously known as the Great North Coast Road, being renamed as the Bruce Highway in 1934 after the state's Minister for Public Works, ...

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 ...

Watercourse
A stream is a continuous body of water, body of surface water Current (stream), flowing within the stream bed, bed and bank (geography), banks of a channel (geography), 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 river, intermittent streams are known, amongst others, as brook, creek, rivulet, rill, run, tributary, feeder, freshet, narrow river, and streamlet. The flow of a stream is controlled by three inputs – surface runoff (from precipitation or meltwater), daylighting (streams), daylighted subterranean river, subterranean water, and surfaced groundwater (Spring (hydrology), 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 pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bureau Of Meteorology
The Bureau of Meteorology (BOM or BoM) is an executive agency of the Government of Australia, Australian Government that is responsible for providing Weather forecasting, weather forecasts and Meteorology, meteorological services to Australia and neighbouring countries. It was established in 1906 under the Meteorology Act (Cth), and brought together the States and territories of Australia, state meteorological services that existed before then. The states officially transferred their weather recording responsibilities to the Bureau of Meteorology on 1 January 1908. History The Bureau of Meteorology was established on 1 January 1908 following the passage of the ''Meteorology Act 1906''. Prior to Federation of Australia, Federation in 1901, each colony had had its own meteorological service, with all but two colonies also having a subsection devoted to astronomy. In August 1905, federal home affairs minister Littleton Groom surveyed state governments for their willingness to cede ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
