Gilbert River (Queensland)
The Gilbert River is located in Far North Queensland, Australia. When combined with the Einasleigh River, the river system is the largest river system in northern Australia. Features and location The Gilbert River rises below Conical Hill in the Einasleigh Uplands, draining the eastern slopes of the Gregory Range and the western slopes of the Newcastle Range, north of . The river flows generally northwest, joined by forty tributaries that drain the Blackbraes National Park including, from source to mouth, the Styx, Percy, Robertson, Langdon, Little, and Einasleigh rivers and numerous creeks. North of the Gilbert discharges into the Gulf of Carpentaria. However, northwest of an anabranch of the river forms confluence with the Smithburne River, also emptying into the Gulf. The Gilbert River has a catchment area of of which , or a third of the total catchment, is a vast estuarine delta approximately wide that largely consists of tidal flats and mangrove swamps across the G ...

John Gilbert (naturalist)
John Gilbert (14 March 1812 – 28 June 1845) was an English naturalist and explorer. Gilbert is often cited in the earliest descriptions of many Australian animals, many of which were unrecorded in European literature, and some of these are named for him by those authors. Gilbert was sent to the newly founded Swan River Colony and made collections and notes on the unique birds and mammals of the surrounding region. He later joined expeditions to remote parts the country, continuing to make records and collections until he was killed during a violent altercation at Mitchell River (Queensland) on the Cape York Peninsula. Early life John Gilbert was born on 14 March 1812 in Newington Butts, south London, England and was christened on 25 October 1812 at Spa Fields Lady Huntingdons, Clerkenwell, London. His father was William and his mother Ann, who were from nearby villages in Kent. Gilbert was a taxidermist for the Zoological Society of London, where he met John Gould. Gould had ...

Einasleigh Uplands
The Einasleigh Uplands is an interim Australian bioregion, with vegetation consisting of savanna and woodland located on a large plateau in inland Queensland, Australia. It corresponds to the Einasleigh Uplands savanna ecoregion, as identified by the World Wildlife Fund. Location and description This area is inland from the moist Queensland coast but is not as dry as the Brigalow Belt and the Mitchell Grass Downs savannas to the south, while the Cape York Peninsula to the north is lower-lying and wetter. The region contains a number of specialised habitats that add to the variety of wildlife found here. These include lava tubes and caves such as those of Chillagoe. The uplands are an area of eroded volcanic rock on and to the west of the Atherton Tableland in the northern section of Australia's Great Dividing Range running inland as far as the town of Croydon in the southwest. The plateau is covered in grassland dotted with eucalyptus trees and cut through with ridges, gorges ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monsoon
A monsoon () is traditionally a seasonal reversing wind accompanied by corresponding changes in precipitation but is now used to describe seasonal changes in atmospheric circulation and precipitation associated with annual latitudinal oscillation of the Intertropical Convergence Zone (ITCZ) between its limits to the north and south of the equator. Usually, the term monsoon is used to refer to the rainy phase of a seasonally changing pattern, although technically there is also a dry phase. The term is also sometimes used to describe locally heavy but short-term rains. The major monsoon systems of the world consist of the West African, Asia–Australian, the North American, and South American monsoons. The term was first used in English in British India and neighboring countries to refer to the big seasonal winds blowing from the Bay of Bengal and Arabian Sea in the southwest bringing heavy rainfall to the area. Etymology The etymology of the word monsoon is not wholl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 groundwater ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gulf Country
The Gulf Country is the region of woodland and savanna grassland surrounding the Gulf of Carpentaria in north western Queensland and eastern Northern Territory on the north coast of Australia. The region is also called the Gulf Savannah. It contains large reserves of zinc, lead and silver. The Gulf Country is crossed by the Savannah Way highway. Location and description The Gulf Country is a block of dry savanna between the wetter areas of Arnhem Land and the Top End of the Northern territory to the west and the Cape York Peninsula of Far North Queensland to the east, while to the south and east lie upland plains of Mitchell grasses and the Einasleigh Uplands. The Northern Territory side of the area is the Gulf Fall area of sandstone slopes and gorges draining the interior uplands into the gulf. The main land uses in the Gulf Country are beef cattle and mining. The region covers an area of . The landscape is generally flat and low-lying tropical savannah cut through with ri ...

Swamp
A swamp is a forested wetland.Keddy, P.A. 2010. Wetland Ecology: Principles and Conservation (2nd edition). Cambridge University Press, Cambridge, UK. 497 p. Swamps are considered to be transition zones because both land and water play a role in creating this environment. Swamps vary in size and are located all around the world. The water of a swamp may be fresh water, brackish water, or seawater. Freshwater swamps form along large rivers or lakes where they are critically dependent upon rainwater and seasonal flooding to maintain natural water level fluctuations.Hughes, F.M.R. (ed.). 2003. The Flooded Forest: Guidance for policy makers and river managers in Europe on the restoration of floodplain forests. FLOBAR2, Department of Geography, University of Cambridge, Cambridge, UK. 96 p. Saltwater swamps are found along tropical and subtropical coastlines. Some swamps have hammock (ecology), hammocks, or dry-land protrusions, covered by aquatic vegetation, or vegetation that tolerates ...

Mangrove
A mangrove is a shrub or tree that grows in coastal saline water, saline or brackish water. The term is also used for tropical coastal vegetation consisting of such species. Mangroves are taxonomically diverse, as a result of convergent evolution in several plant families. They occur worldwide in the tropics and subtropics and even some temperate coastal areas, mainly between latitudes 30° N and 30° S, with the greatest mangrove area within 5° of the equator. Mangrove plant families first appeared during the Late Cretaceous to Paleocene epochs, and became widely distributed in part due to the plate tectonics, movement of tectonic plates. The oldest known fossils of Nypa fruticans, mangrove palm date to 75 million years ago. Mangroves are salt-tolerant trees, also called halophytes, and are adapted to live in harsh coastal conditions. They contain a complex salt filtration system and a complex root system to cope with saltwater immersion and wave action. They are ad ...

Bureau Of Meteorology (Australia)
The Bureau of Meteorology (BOM or BoM) is an executive agency of the Australian Government responsible for providing weather services to Australia and surrounding areas. It was established in 1906 under the Meteorology Act, and brought together the 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 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 control, finding South Australia and Victoria unwilling. However, at a ministerial conference in April 1906 the state governments agreed to transfer responsibility for m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Estuarine
An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. Estuaries form a transition zone between river environments and maritime environments and are an example of an ecotone. Estuaries are subject both to marine influences such as tides, waves, and the influx of saline water, and to fluvial influences such as flows of freshwater and sediment. The mixing of seawater and freshwater provides high levels of nutrients both in the water column and in sediment, making estuaries among the most productive natural habitats in the world. Most existing estuaries formed during the Holocene epoch with the flooding of river-eroded or glacially scoured valleys when the sea level began to rise about 10,000–12,000 years ago. Estuaries are typically classified according to their geomorphological features or to water-circulation patterns. They can have many different names, such as bays, harb ...

Queensland Government
The Queensland Government is the democratic administrative authority of the Australian state of Queensland. The Government of Queensland, a parliamentary constitutional monarchy was formed in 1859 as prescribed in its Constitution, as amended from time to time. Since the Federation of Australia in 1901, Queensland has been a State of Australia, with the Constitution of Australia regulating the relationships between all state and territory governments and the Australian Government. Under the Australian Constitution, all states and territories (including Queensland) ceded powers relating to certain matters to the federal government. The government is influenced by the Westminster system and Australia's federal system of government. The Governor of Queensland, as the representative of Charles III, King of Australia, holds nominal executive power, although in practice only performs ceremonial duties. In practice executive power lies with the Premier and Cabinet. The Cabinet of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
