Hann River (Queensland)
The Hann River is a river in Far North Queensland, Australia. The headwaters of the river rise in the Great Dividing Range on Cape York Peninsula northeast of the settlement of Kimba. The river flows in a north easterly direction, joined by four minor tributaries, crosses the Peninsula Developmental Road and then enters the Rinyirru National Park where it forms a series of braided channels then re-forms to a single channel and discharges into the North Kennedy River northwest of Lakefield. The river descends over its course. The river has a catchment area of of which an area of is composed of estuarine wetlands. The floodplain is composed of reddish grey sand loam produced from the underlying sand material of Cainozoic age. The underlying geology is predominantly alluvium of Quaternary age with areas of older rock made up of sandstone of Middle Jurassic age in the Bathurst Range and the granite of Late Silurian age in the Great Dividing Range of the upper catchment ...

William Hann
William Hann (26 February 1837 – 5 April 1889) was a pastoralist and explorer in northern Queensland, Australia. His expedition in 1872 found the first indications of the Palmer River goldfield. Early life He was born in Wiltshire, England, on 26 February 1837. Fellow explorer Frank Hann was his younger brother. North Queensland exploration In 1871, Hann wrote to the Queensland minister for public works and goldfields William Henry Walsh with the proposition of a northern expedition. In Brisbane in early 1872, Hann presented geological specimens and attended a meeting with Premier Arthur Hunter Palmer and the colonial secretary about the proposal. In February 1872 the Queensland government approved the proposal for an expedition with the aim of: 'ascertaining, as far north as the 14th parallel of latitude, the character of the country and its mineral resources, with the view to future settlement and occupation.' The expedition members consisted of: *William Hann (1837– ... [...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] |
James Venture Mulligan
James Venture Mulligan (13 February 1837 – 24 August 1907) was an Ireland-born Australian prospector and explorer. Early life Mulligan was born in Drumgooland, County Down and emigrated to Australia at the age of 21 in 1860. He settled at Armidale in the British colony of New South Wales where he became a butcher and a publican. While residing there, Mulligan became involved in gold prospecting at the nearby Rocky River diggings. Prospecting in Queensland In 1867, Mulligan ventured north to the colony of Queensland to further pursue aspirations of fortune from gold diggings. After mediocre success at Gympie, Mulligan went to the Etheridge goldfields in the early 1870s. From there he later led a group to find payable gold on the Palmer River in Far North Queensland which had been reported by William Hann. On 30 June 1873, despite the local Aboriginal people attempting to burn down their tents, the group returned with 102 ounces of payable gold. Mulligan reported his find ...

Royal Geographical Society Of Queensland
On 22 June 1883, the Geographical Society of Australasia started at a meeting in Sydney, New South Wales, Australia. A branch was formed in Victoria in the same year. In July 1885, both the Queensland and the South Australian branches started. In July 1886 the society became the Royal Geographical Society of Australasia. The New South Wales branch's new constitution in 1886 widened its scope to encourage interest in scientific, commercial, educational and historical aspects of geography. The Society sponsored several important expeditions, notably the New Guinea Exploration Expedition in 1885, whose members included zoologist Wilhelm Haacke, erstwhile director of the South Australian Museum. The Victorian branch amalgamated with the Victorian Historical Society, while the New South Wales branch had ceased to function by the early 1920s. The South Australian and Queensland branches continue as the Royal Geographical Society of South Australia and Royal Geographical Society of Que ...

Ironbark
Ironbark is a common name of a number of species in three taxonomic groups within the genus ''Eucalyptus'' that have dark, deeply furrowed bark. Instead of being shed annually as in many of the other species of ''Eucalyptus'', the dead bark accumulates on the trees, forming the fissures. It becomes rough after drying out and becomes impregnated with kino (red gum), a dark red tree sap exuded by the tree. The tree is so named for the apparent resemblance of its bark to iron slag. The bark is resistant to fire and heat and protects the living tissue within the trunk and branches from fire. In cases of extreme fire, where leaves and shoots are removed, the protective bark aids in protecting epicormic buds which allow the tree to reshoot. Being a very dense, hard wood, a length of ironbark is often used as a bug shoe on the bottom of a ship's skeg to protect it from shipworms. Ironbark was widely used in the piles of 19th and early 20th century bridges and wharves in New Zealand. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moreton Bay Ash
''Corymbia tessellaris'', commonly known as carbeen or Moreton Bay ash, is a species of tree that is endemic to north-eastern Australia. It has rough, tessellated bark on the lower trunk abruptly changing to smooth, whitish bark above, narrow lance-shaped adult leaves, flower buds in groups of three or seven, white flowers and cylindrical or urn-shaped fruit Description ''Corymbia tessellaris'' is a tree that typically grows to a height of and forms a lignotuber. The trunk is almost always straight, making up a half to two thirds of the total tree height, with a crown of slender branches. It has rough, tessellated greyish bark on the lower of the trunk, abruptly changing to smooth whitish bark above. Young plants and coppice regrowth have lance-shaped leaves that are arranged in opposite pairs at first, long and wide, tapering to a short petiole or sessile. Adult leaves are arranged alternately, the same shade of green to greyish on both sides, narrow lance-shaped to line ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stringybark
A stringybark can be any of the many ''Eucalyptus'' species which have thick, fibrous bark. Like all eucalypts, stringybarks belong to the family Myrtaceae. In exceptionally fertile locations some stringybark species (in particular messmate stringybark (''Eucalyptus obliqua'') can be very large, reaching over 80 metres in height. More typically, stringybarks are medium-sized trees in the 10 to 40 metre range. Early European colonists often used the bark for roofing and walls of huts. The term ''stringybark'' is a descriptive, vernacular name and does not imply any special taxonomic relationship within the genus ''Eucalyptus''. For example, scientists consider ''Eucalyptus obliqua'' to not be closely related to the other stringybarks, because of the gumnut shape. And ''Eucalyptus acmenoides'' is part of the ''mahogany'' group of eucalyptus. Also as the gumnuts are a different shape, despite the bark being somewhat stringy.Forest Trees of Australia, D.J.

Loam
Loam (in geology and soil science) is soil composed mostly of sand (particle size > ), silt (particle size > ), and a smaller amount of clay (particle size < ). By weight, its mineral composition is about 40–40–20% concentration of sand–silt–clay, respectively. These proportions can vary to a degree, however, and result in different types of loam soils: sandy loam, silty loam, clay loam, sandy clay loam, silty clay loam, and loam. In the , textural classification triangle, the only soil that is not predominantly sand, silt, or clay is called "loam". Loam soils generally contain more nutrients, moisture, and |
Floodplain
A floodplain or flood plain or bottomlands is an area of land adjacent to a river which stretches from the banks of its channel to the base of the enclosing valley walls, and which experiences flooding during periods of high discharge.Goudie, A. S., 2004, ''Encyclopedia of Geomorphology'', vol. 1. Routledge, New York. The soils usually consist of clays, silts, sands, and gravels deposited during floods. Because the regular flooding of floodplains can deposit nutrients and water, floodplains frequently have high soil fertility; some important agricultural regions, such as the Mississippi river basin and the Nile, rely heavily on the flood plains. Agricultural regions as well as urban areas have developed near or on floodplains to take advantage of the rich soil and fresh water. However, the risk of flooding has led to increasing efforts to control flooding. Formation Most floodplains are formed by deposition on the inside of river meanders and by overbank flow. Whereve ...

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] |
