River Fork
A river fork is where a river is connected to two or more clearly and equally distinct branches. It describes both tributaries and distributaries. A typical river fork is usually two tributaries merging (a confluence), such as the Nile proper created at that of the Blue Nile and White Nile, though the term can be used when a single or main channel of a river bifurcates into distributaries, a large instance being the Mississippi at the upper end of the Atchafalaya River. Most river deltas fork several times, occasionally forming multiple clustered, elongated islands.

River Forks At Creek Fen - Geograph
A river is a natural stream of fresh water that flows on land or inside caves towards another body of water at a lower elevation, such as an ocean, lake, or another river. A river may run dry before reaching the end of its course if it runs out of water, or only flow during certain seasons. Rivers are regulated by the water cycle, the processes by which water moves around the Earth. Water first enters rivers through precipitation, whether from rainfall, the runoff of water down a slope, the melting of glaciers or snow, or seepage from aquifers beneath the surface of the Earth. Rivers flow in channeled watercourses and merge in confluences to form drainage basins, or catchments, areas where surface water eventually flows to a common outlet. Rivers have a great effect on the landscape around them. They may regularly overflow their banks and flood the surrounding area, spreading nutrients to the surrounding area. Sediment or alluvium carried by rivers shapes the landscape aro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atchafalaya River
The Atchafalaya River () is a distributary of the Mississippi River and Red River of the South, Red River in south central Louisiana in the United States. It flows south, just west of the Mississippi River, and is the fifth largest river in North America, by discharge. The name ''Atchafalaya'' comes from Choctaw language, Choctaw for 'long river', from , 'river', and , 'long'. Atchafalaya Basin The Atchafalaya River is navigable and provides a significant industrial shipping channel for the state of Louisiana. It is the cultural heart of the Cajun Country. The maintenance of the river as a navigable channel of the Mississippi River has been a significant project of the U.S. Army Corps of Engineers for more than a century. Natural development of the river channel, coupled with channel training and maintenance for flood control and navigation, have combined to isolate the river from the swamp. The river valley forms the Atchafalaya Basin and Atchafalaya Swamp located in south ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River Delta
A river delta is a landform, archetypically triangular, created by the deposition of the sediments that are carried by the waters of a river, where the river merges with a body of slow-moving water or with a body of stagnant water. The creation of a river delta occurs at the '' river mouth'', where the river merges into an ocean, a sea, or an estuary, into a lake, a reservoir, or (more rarely) into another river that cannot carry away the sediment supplied by the feeding river. Etymologically, the term ''river delta'' derives from the triangular shape (Δ) of the uppercase Greek letter delta. In hydrology, the dimensions of a river delta are determined by the balance between the watershed processes that supply sediment and the watershed processes that redistribute, sequester, and export the supplied sediment into the receiving basin. River deltas are important in human civilization, as they are major agricultural production centers and population centers. They can provide ...

Tributary
A tributary, or an ''affluent'', is a stream or river that flows into a larger stream (''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 into which they flow, drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean, another river, or into an endorheic basin. The Irtysh is a chief tributary of the Ob (river), 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. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River Morphology
The terms river morphology and its synonym stream morphology are used to describe the shapes of river channels and how they change in shape and direction over time. The morphology of a river channel is a function of a number of processes and environmental conditions, including the composition and erodibility of the bed and banks (e.g., sand, clay, bedrock); erosion comes from the power and consistency of the current, and can affect the formation of the river's path. It also can be affected by vegetation and the rate of plant growth; the availability of sediment; the size and composition of the sediment moving through the channel; the rate of sediment transport through the channel and the rate of deposition on the floodplain, banks, bars, and bed; and regional aggradation or degradation due to subsidence or uplift. River morphology can also be affected by human interaction. An example of human-induced change in river morphology is dam construction, which alters the ebb flow of ...

Island
An island or isle is a piece of land, distinct from a continent, completely surrounded by water. There are continental islands, which were formed by being split from a continent by plate tectonics, and oceanic islands, which have never been part of a continent. Oceanic islands can be formed from volcano, volcanic activity, grow into atolls from coral reefs, and form from sediment along shorelines, creating barrier islands. River islands can also form from sediment and debris in rivers. Artificial islands are those made by humans, including small rocky outcroppings built out of lagoons and large-scale land reclamation projects used for development. Islands are host to diverse plant and animal life. Oceanic islands have the sea as a natural barrier to the introduction of new species, causing the species that do reach the island to evolve in isolation. Continental islands share animal and plant life with the continent they split from. Depending on how long ago the continental is ...

River Bifurcation
River bifurcation (from , fork) occurs when a river (a ''bifurcating river'') flowing in a single channel (hydrology), channel separates into two or more separate streams (called distributary, ''distributaries'') which then continue downstream (hydrology), downstream. Some rivers form complex networks of distributaries, typically in their delta (river), deltas. If the streams eventually merge again or empty into the same body of water, then the bifurcation forms a river island. River bifurcation may be temporary or semi-permanent, depending on the strength of the material that is dividing the two distributaries. For example, a mid-stream island of soil or silt in a delta is most likely temporary, due to low material strength. A location where a river divides around a rock fin, e.g. a volcanically formed Dike (geology), dike, or a mountain, may be more lasting as a result of higher material strength and resistance to weathering and erosion. A bifurcation may also be man-made, for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White Nile
The White Nile ( ') is a river in Africa, the minor of the two main tributaries of the Nile, the larger being the Blue Nile. The name "White" comes from the clay sediment carried in the water that changes the water to a pale color. In the strict meaning, "White Nile" refers to the river formed at Lake No, at the confluence of the Bahr al Jabal and Bahr el Ghazal Rivers. In the wider sense, "White Nile" refers to all the stretches of river draining from Lake Victoria through to the merger with the Blue Nile: the "Victoria Nile" from Lake Victoria via Lake Kyoga to Lake Albert, then the "Albert Nile" to the South Sudan border, and then the "Mountain Nile" or "Bahr-al-Jabal" down to Lake No. "White Nile" may sometimes include the headwaters of Lake Victoria, the most remote of which being from the Blue Nile. The 19th-century search by Europeans for the source of the Nile was mainly focused on the White Nile, which disappeared into the depths of what was then known as "Darkest ...
