Wickham River
The Wickham River is an ephemeral river, located in the Victoria Bonaparte bioregion of the Northern Territory in Australia. Course and features The headwaters of the Wickham River are situated on an area of rugged stony hills and a sandstone plateau as the river rises on the southeastern slopes of Mt Kimon. It flows generally northeast, joined by seven tributaries including the Humbert River, Soda Springs Creek, Depot Creek and Broadarrow Creek and through one permanent waterhole, Johnston Billabong, before reaching its confluence with the Victoria River, south of the Fitzgerald Range near Pompey Knob. The Wickham River descends over its course. The Judbarra / Gregory National Park was established in 1981 encompassing much of the catchment. Mount Sanford was exhumed to enlarge the park boundaries in 1996. The Wickham flows for only six months of the year, during the wet season. During the dry season, a string of waterholes form along the course of the river some of which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Clements Wickham
John Clements Wickham (21 November 17986 January 1864) was a Scottish explorer, naval officer, magistrate and administrator. He was first lieutenant on during its second survey mission, 1831–1836, under captain Robert FitzRoy. The young naturalist and geologist Charles Darwin was a supernumerary on the ship, and his journal was published as ''The Voyage of the Beagle''. After that expedition, Wickham was promoted to Commander and made captain of the ''Beagle'' on its third voyage, from 1837 and conducted various maritime expeditions and hydrographic surveys along the Australian coastline. In 1843, after his retirement from the Royal Navy, Wickham was made Police Magistrate and, later, Government Resident of the Moreton Bay District, in the Colony of New South Wales (NSW). Wickham retired in 1859, when the Moreton Bay District was separated from NSW, forming basis of the Colony of Queensland. When the Queensland and NSW governments disagreed over which was responsible f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Billabong
Billabong ( ) is an Australian term for an oxbow lake, an isolated pond left behind after a river changes course. Billabongs are usually formed when the path of a creek or river changes, leaving the former branch with a dead end. As a result of the arid Australian climate in which these "dead rivers" are often found, billabongs fill with water seasonally but can be dry for a greater part of the year. Etymology The etymology of the word ''billabong'' is disputed. The word is most likely derived from the Wiradjuri term ''bilabaŋ'', which means "a watercourse that runs only after rain". It is derived from ''bila'', meaning "river", It may have been combined with ''bong'' or ''bung'', meaning "dead". One source, however, claims that the term is of Scottish Gaelic origin. Billabongs were significant because they held water longer than parts of rivers; it was important for people to identify and name these areas.

Indigenous Australian
Indigenous Australians or Australian First Nations are people with familial heritage from, and membership in, the ethnic groups that lived in Australia before British colonisation. They consist of two distinct groups: the Aboriginal peoples of the Australian mainland and Tasmania, and the Torres Strait Islander peoples from the seas between Queensland and Papua New Guinea. The term Aboriginal and Torres Strait Islander peoples or the person's specific cultural group, is often preferred, though the terms First Nations of Australia, First Peoples of Australia and First Australians are also increasingly common; 812,728 people self-identified as being of Aboriginal and/or Torres Strait Islander origin in the 2021 Australian Census, representing 3.2% of the total population of Australia. Of these indigenous Australians, 91.4% identified as Aboriginal; 4.2% identified as Torres Strait Islander; while 4.4% identified with both groups.

Lawrence Wells
Lawrence Allen "Larry" Wells (30 April 1860 – 11 May 1938), frequently spelled Laurence Allen Wells, was an Australian explorer. Wells was born at Yallum Station near Penola, South Australia and grew up in the Mount Gambier, South Australia district, and after a short stint in a merchants office, joined the South Australian Survey Department in October 1878. In 1883 the surveyor General, G.W. Goyder, offered him the Assistant Surveyor position to the Northern Territory and Queensland Border Survey Expedition, under Augustus Poeppel. This task took almost three years to complete, the honours of driving in the last peg being shared with assistant John Carruthers. and Wells spent the next couple of years working in the far north of S.A. and the N.T., surveying pastoral boundaries. In 1891 he was appointed surveyor to the Elder Scientific Exploration Expedition, under David Lindsay. Lindsay's instructions were to investigate the remaining "blanks on the map" of Australia, ...

Spring (hydrosphere)
A spring is a point of exit at which groundwater from an aquifer flows out on top of Earth's crust (pedosphere) and becomes surface water. It is a component of the hydrosphere. Springs have long been important for humans as a source of fresh water, especially in arid regions which have relatively little annual rainfall. Springs are driven out onto the surface by various natural forces, such as gravity and hydrostatic pressure. Their yield varies widely from a volumetric flow rate of nearly zero to more than for the biggest springs. Formation Springs are formed when groundwater flows onto the surface. This typically happens when the groundwater table reaches above the surface level. Springs may also be formed as a result of karst topography, aquifers, or volcanic activity. Springs also have been observed on the ocean floor, spewing hot water directly into the ocean. Springs formed as a result of karst topography create karst springs, in which ground water travel ...

Dry Season
The dry season is a yearly period of low rainfall, especially in the tropics. The weather in the tropics is dominated by the tropical rain belt, which moves from the northern to the southern tropics and back over the course of the year. The temperate counterpart to the tropical dry season is summer or winter. Rain belt The tropical rain belt lies in the southern hemisphere roughly from October to March; during that time the northern tropics have a dry season with sparser precipitation, and days are typically sunny throughout. From April to September, the rain belt lies in the northern hemisphere, and the southern tropics have their dry season. Under the Köppen climate classification, for tropical climates, a dry season month is defined as a month when average precipitation is below . The rain belt reaches roughly as far north as the Tropic of Cancer and as far south as the Tropic of Capricorn. Near these latitudes, there is one wet season and one dry season annually. At ...

Wet Season
The wet season (sometimes called the Rainy season) is the time of year when most of a region's average annual rainfall occurs. It is the time of year where the majority of a country's or region's annual precipitation occurs. Generally, the season lasts at least a month. The term ''green season'' is also sometimes used as a euphemism by tourist authorities. Areas with wet seasons are dispersed across portions of the tropics and subtropics. Under the Köppen climate classification, for tropical climates, a wet season month is defined as a month where average precipitation is or more. In contrast to areas with savanna climates and monsoon regimes, Mediterranean climates have wet winters and dry summers. Dry and rainy months are characteristic of tropical seasonal forests: in contrast to tropical rainforests, which do not have dry or wet seasons, since their rainfall is equally distributed throughout the year.Elisabeth M.

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] |
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] |
