Leichhardt River
The Leichhardt River is a river in north-west Queensland, Australia. Course The source of the river is in the Selwyn Range under Rifle Creek Hill and fed by Rifle Creek approximately south of the mining town Mount Isa. It runs in a generally northerly direction almost parallel with the Diamantina Developmental Road until it reaches Mount Isa and crosses the Barkly Highway. It continues in a north easterly direction across the Gulf Country passing through Lake Moondarra past Glenroy Station then through Lake Julius. It then bears east then north again almost parallel with the Burke Developmental Road until crossing it near Nardoo. Continuing north past Augustus Downs Station to its mouth at the Gulf of Carpentaria. The river was named by explorer and surveyor Augustus Charles Gregory after the early explorer of Australia, Ludwig Leichhardt. Gregory chose the name because:"Two days' journey S.E. brought us to a river 100 yards wide, in detached pools. (Latitude 18 degrees 1 ...

Ludwig Leichhardt
Friedrich Wilhelm Ludwig Leichhardt (; 23 October 1813 – ), known as Ludwig Leichhardt, was a German explorer and naturalist, most famous for his exploration of northern and central Australia.Ken Eastwood,'Cold case: Leichhardt's disappearance', Australian Geographic, AG Online, accessed online 7 August 2010 Early life Leichhardt was born on 23 October 1813 in the hamlet of Sabrodt near the village of Trebatsch, today part of Tauche, in the Prussian Province of Brandenburg (now within the Federal Republic of Germany). He was the fourth son and sixth of the eight children of Christian Hieronymus Matthias Leichhardt, farmer and royal inspector and his wife Charlotte Sophie, ''née'' Strählow. Between 1831 and 1836 Leichhardt studied philosophy, language, and natural sciences at the Universities of Göttingen and Berlin but never received a university degree. He moved to England in 1837, continued his study of the natural sciences at various places, including the British Museu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Catchment Area (human Geography)
A catchment area in human geography, is the area from which a location, such as a city, service or institution, attracts a population that uses its services and economic opportunities. Catchment areas may be defined based on from where people are naturally drawn to a location (for example, a labour catchment area) or as established by governments or organizations such as education authorities or healthcare providers, for the provision of services. Governments and community service organizations often define catchment areas for planning purposes and public safety such as ensuring universal access to services like fire departments, police departments, ambulance bases and hospitals. In business, a catchment area is used to describe the influence from which a retail location draws its customers. Airport catchment areas can inform efforts to estimate route profitability. A health catchment area is of importance in public health, and healthcare planning, as it helps in resource allocatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rivers Of Queensland
The principal topographic feature of Queensland is the series of low highlands and plateaus called the Great Dividing Range, which extend from north to south roughly parallel to the coast of the Coral Sea of the South Pacific Ocean. The four main categories of rivers in Queensland are those that rise on the eastern slopes of the Great Dividing Range and flow eastwards to the sea, the Coastal rivers; those that rise on the other side of the crest of the range and flow north-westward, towards the Gulf of Carpentaria, the Gulf rivers; those that also rise on the other side of the crest of the range and flow south-westward, forming part of the Murray–Darling basin, the Murray–Darling rivers; and those that generally rise in the west of the state and flow south-westward, towards the Lake Eyre basin, the Lake Eyre rivers. One river is isolated and does not flow towards any other basin or sea. Major rivers The following rivers are the longest river systems, by length. Coastal rivers ...

Paleontologist
Paleontology, also spelled as palaeontology or palæontology, is the scientific study of the life of the past, mainly but not exclusively through the study of fossils. Paleontologists use fossils as a means to classify organisms, measure geologic time, and assess the interactions between prehistoric organisms and their natural environment. While paleontological observations are known from at least the 6th century BC, the foundation of paleontology as a science dates back to the work of Georges Cuvier in 1796. Cuvier demonstrated evidence for the concept of extinction and how life of the past was not necessarily the same as that of the present. The field developed rapidly over the course of the following decades, and the French word ''paléontologie'' was introduced for the study in 1822, which was derived from the Ancient Greek word for "ancient" and words describing relatedness and a field of study. Further advances in the field accompanied the work of Charles Darwin who popu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marsupial
Marsupials are a diverse group of mammals belonging to the infraclass Marsupialia. They are natively found in Australasia, Wallacea, and the Americas. One of marsupials' unique features is their reproductive strategy: the young are born in a relatively undeveloped state and then nurtured within a pouch on their mother's abdomen. Extant marsupials encompass many species, including Kangaroo, kangaroos, Koala, koalas, Opossum, opossums, Phalangeriformes, possums, Tasmanian devil, Tasmanian devils, Wombat, wombats, Wallaby, wallabies, and Bandicoot, bandicoots. Marsupials constitute a clade stemming from the last common ancestor of extant Metatheria, which encompasses all mammals more closely related to marsupials than to Placentalia, placentals. The evolutionary split between placentals and marsupials occurred 125-160 million years ago, in the Middle Jurassic-Early Cretaceous period. Presently, close to 70% of the 334 extant marsupial species are concentrated on the Australian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rifle Creek Dam
Rifle Creek Dam is owned by Mount Isa Mines. A concrete arch dam, it was constructed in 1929 to replace the earlier Experimental Dam (the first arch dam in Queensland, completed in September 1925) as the primary water supply to the town of Mt Isa, and the mine. The initial full supply volume was 600 million gallons (2,727 megalitres), the spillway was raised in 1953, and the current full capacity is 9,500 megalitres. The dam was replaced as Mt Isa's primary water supply by Lake Moondarra following the completion of that dam in 1958. Rifle Creek Dam now serves as a backup water supply for Mt Isa Mines.

Estuary
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 ba ...
