Alligator Rivers
Alligator Rivers is the name of an area in an Arnhem Land region of the Northern Territory of Australia, containing three rivers, the East, West, and South Alligator Rivers. It is regarded as one of the richest biological regions in Australia, with part of the region in the Kakadu National Park. It is an Important Bird Area (IBA), lying to the east of the Adelaide and Mary River Floodplains IBA. It also contains mineral deposits, especially uranium, and the Ranger Uranium Mine is located there. The area is also rich in Australian Aboriginal art, with 1500 sites. The Kakadu National Park is one of the few World Heritage sites on the list because of both its natural and human heritage values. They were explored by Lieutenant Phillip Parker King in 1820, who named them in the mistaken belief that the crocodiles in the estuaries were alligators. Rivers The East Alligator River is about long. After rising in the northern part of the Arnhem Land Plateau, it flows with tributary ...

Mouth (river)
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.

Waterfall
A waterfall is a point in a river or stream where water flows over a vertical drop or a series of steep drops. Waterfalls also occur where meltwater drops over the edge of a tabular iceberg or ice shelf. Waterfalls can be formed in several ways, but the most common method of formation is that a river courses over a top layer of resistant bedrock before falling on to softer rock, which erodes faster, leading to an increasingly high fall. Waterfalls have been studied for their impact on species living in and around them. Humans have had a distinct relationship with waterfalls for years, travelling to see them, exploring and naming them. They can present formidable barriers to navigation along rivers. Waterfalls are religious sites in many cultures. Since the 18th century they have received increased attention as tourist destinations, sources of hydropower, andparticularly since the mid-20th centuryas subjects of research.

Mary River (Northern Territory)
The Mary River flows in the Northern Territory of Australia and is a site of the Mary River National Park. Description The river is approximately long and rises about east of Pine Creek. The catchment area is over but is ephemeral and only flows in the wet season, during the dry it is a series of pools and billabongs. The catchment has several small reserve areas forming the Mary River National Park to help protect it. The Arnhem Highway crosses the river near one of the park areas. It also supports multiple land uses including pastoralism, fishing, mining, defence force, tourism, conservation and horticulture. Pastoralism, particularly cattle grazing is the dominant use taking up 63% of the catchment area. The river has a total of ten tributaries including the Little Mary River, MacKinlay River, Bowerbird Creek, Mingloo Creek and Douglas Creek. It has a mean annual outflow of , Its lower reaches form part of the Adelaide and Mary River Floodplains Important Bird Area ...

Wildman River
The Wildman River is a river in the Darwin Coastal bioregion of the Northern Territory, Australia. Location and features Formed by the confluence of the East and West Branches of the Wildman River, the river rises southwest of Kapalga in the Kakadu National Park, west of the Alligator Rivers watershed. The Wildman River flows generally northeast and then east, joined by its only major tributary, the Alligator Creek. Approximately east of , the river follows a highly meandering course as it reaches the western fringe of the Manassie Floodplain and heads northwest. At this point, the river's eastern bank define a stretch of the western boundary of the Kakadu National Park. The Wildman River reaches its mouth, emptying into Finke Bay in the Van Diemen Gulf of the Timor Sea. The river descends over its course. The river catchment occupies an area of and is wedged between the Mary River catchment to the west and the Alligator Rivers catchment to the east. It has a mean annual ...

Timor Sea
The Timor Sea ( id, Laut Timor, pt, Mar de Timor, tet, Tasi Mane or ) is a relatively shallow sea bounded to the north by the island of Timor, to the east by the Arafura Sea, and to the south by Australia. The sea contains a number of reefs, uninhabited islands and significant hydrocarbon reserves. International disputes emerged after the reserves were discovered resulting in the signing of the Timor Sea Treaty. The Timor Sea was hit by the worst oil spill for 25 years in 2009. It is possible that Australia's first inhabitants crossed the Timor Sea from the Malay Archipelago at a time when sea levels were lower. Etymology The Timor Sea is named after Timor, the island on the other side of the sea's northern coastline. The island's name is a variant of , Malay for "east". In Tetum, the expression () is often used to refer to the Timor Sea. The counterpart of that body of water, the ' Ombai- Wetar Strait', which has smaller waves, is less turbid, and washes most of Ti ...

Uranium Mining
Uranium mining is the process of extraction of uranium ore from the ground. Over 50 thousand tons of uranium were produced in 2019. Kazakhstan, Canada, and Australia were the top three uranium producers, respectively, and together account for 68% of world production. Other countries producing more than 1,000 tons per year included Namibia, Niger, Russia, Uzbekistan, the United States, and China. Nearly all of the world's mined uranium is used to power nuclear power plants. Historically uranium was also used in applications such as uranium glass or ferrouranium but those applications have declined due to the radioactivity of uranium and are nowadays mostly supplied with a plentiful cheap supply of depleted uranium which is also used in uranium ammunition. In addition to being cheaper, depleted uranium is also less radioactive due to a lower content of short-lived and than natural uranium. Uranium is mined by in-situ leaching (57% of world production) or by conventional ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Daly River (Northern Territory)
The Daly River is a river in the Northern Territory of Australia. Settlement on the river is centred on the Aboriginal community of Nauiyu, originally the site of a Catholic mission, as well as the town of Daly River itself, at the river crossing a few kilometres to the south. The Daly River is part of the Daly Catchment that flows from northern Northern Territory to central Northern Territory. The Daly River flows from the confluence of the Flora River and Katherine River to its mouth on the Timor Sea. History The traditional owners of the area are the Mulluk-Mulluk people. Boyle Travers Finniss named the river after Sir Dominick Daly, the Governor of South Australia, as the Northern Territory was at that time part of South Australia. The region then lay untouched by Europeans until 1882 when copper was discovered. Floods Like other rivers of the top end, the Daly is prone to seasonal flooding. Major flood events devastated the town of Daly River in 1899 and 1957, cau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tributary
A tributary, or affluent, is a stream or river that flows into a larger stream or main stem (or parent) river or a lake. A tributary does not flow directly into a sea or ocean. Tributaries and the main stem river drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean. The Irtysh is a chief tributary of the Ob river and is also the longest tributary river in the world with a length of . The Madeira River is the largest tributary river by volume in the world with an average discharge of . A confluence, where two or more bodies of water meet, usually refers to the joining of tributaries. The opposite to a tributary is a distributary, a river or stream that branches off from and flows away from the main stream. PhysicalGeography.net, Michael Pidwir ...
