An anabranch is a section of a river or stream that diverts from the main channel or stem of the watercourse and rejoins the main stem downstream. Local anabranches can be the result of small islands in the watercourse. In larger anabranches, the flow can diverge for a distance of several or even hundreds of kilometers before rejoining the main channel.
The term anabranch, in its hydrological meaning, is used more frequently in Australia than in the rest of the English-speaking world.
The term anabranching river describes a river with many anabranches, whilst an anastomosing river is an organic-rich subset of this river type. [1]
The term braided river describes watercourses which are divided by small islands into multiple channel threads within a single main channel, but the term does not describe the multiple channels of an anabranching river.
A distributary is a branch of a river that does not rejoin the main channel; these are common on and near river deltas.
A bayou is often an anabranch.
An anabranch that gets cut off from the main channel becomes an oxbow lake, known in Australia as a billabong.
A distributary, or a distributary channel, is a stream that branches off and flows away from a main stream channel, a phenomenon known as river bifurcation. A distributary is effectively the opposite of a tributary, which is a stream that flows towards and into another stream or river. Distributaries are often found where a river approaches a lake or an ocean and divides into distributary networks; as such they are a common feature of river deltas. They can also occur inland, on alluvial fans, or where a tributary stream bifurcates as it nears its confluence with a larger stream. In some cases, a minor distributary can divert so much water from the main channel that it can later become the main route.
A braided river consists of a network of river channels separated by small, often temporary, islands called braid bars or, in British English usage, aits or eyots.
The Fraser River is the longest river within British Columbia, Canada, rising at Fraser Pass near Blackrock Mountain in the Rocky Mountains and flowing for 1,375 kilometres (854 mi), into the Strait of Georgia just south of the City of Vancouver. The river's annual discharge at its mouth is 112 cubic kilometres (27 cu mi) or 3,550 cubic metres per second (125,000 cu ft/s), and each year it discharges about 20 million tons of sediment into the ocean.
A streambed or stream bed is the bottom of a stream or river (bathymetry) and is confined within a channel, or the banks (bank of the waterway. Usually, the bed does not contain terrestrial vegetation and instead supports different types of aquatic vegetation, depending on the type of streambed material and water velocity. Streambeds are what would be left once a stream is no longer in existence. The beds are usually well preserved even if they get buried because the banks and canyons made by the stream are typically hard, although soft sand and debris often fill the bed. Dry, buried streambeds can actually be underground water pockets. During times of rain, sandy streambeds can soak up and retain water, even during dry seasons, keeping the water table close enough to the surface to be obtainable by local people.
The Darling River is the third-longest river in Australia, measuring 1,472 kilometres (915 mi) from its source in northern New South Wales to its confluence with the Murray River at Wentworth. Including its longest contiguous tributaries it is 2,844 km (1,767 mi) long, making it the longest river system in Australia. The Darling River is the outback's most famous waterway.
An anastomosis is a connection or opening between two things that are normally diverging or branching, such as between blood vessels, leaf veins, or streams. Such a connection may be normal or abnormal ; it may be acquired or innate ; and it may be natural or artificial. The reestablishment of an anastomosis that had become blocked is called a reanastomosis. Anastomoses that are abnormal, whether congenital or acquired, are often called fistulas.
Wadi, alternatively wād, Maghrebi Arabic Oued, Hebrew: וָאדִי, romanized: wadi, lit. 'wadi') is the Arabic term traditionally referring to a river valley. In some instances, it may refer to a wet (ephemeral) riverbed that contains water only when heavy rain occurs.
The Culgoa River is a river that is part of the Darling catchment within the Murray–Darling basin and is located in South West Queensland.
Gwydir River, a major inland perennial river of the Barwon catchment within the Murray–Darling basin, is located in the Northern Tablelands, North West Slopes, and Orana districts of New South Wales, Australia.
The Colne is a river and a tributary of the River Thames in England. Just over half its course is in south Hertfordshire. Downstream, it forms the boundary between Buckinghamshire and the London Borough of Hillingdon. The confluence with the River Thames is on the Staines reach at Staines-upon-Thames.
The Warrego River is an intermittent river that is part of the Darling catchment within the Murray–Darling basin, which is located in South West Queensland and in the Orana region of New South Wales, Australia. The Warrego River is the northernmost tributary of the Darling River.
Eucalyptus camaldulensis, commonly known as the river red gum, is a species of flowering plant in the family Myrtaceae, and is endemic to Australia. It is a tree with smooth white or cream-coloured bark, lance-shaped or curved adult leaves, flower buds in groups of seven or nine, white flowers and hemispherical fruit with the valves extending beyond the rim. A familiar and iconic tree, it is seen along many watercourses across inland Australia, providing shade in the extreme temperatures of central Australia.
In geography, an arm is a narrow extension, inlet, or smaller reach, of water flowing out from a much larger body of water, such as an ocean, a sea, or a lake. Although different geographically, a sound or bay may also be called an arm.
A river island is any exposed landmass surrounded by river water. Properly defined, it excludes shoals between seasonally varying flows and may exclude semi-coastal islands in river deltas such as Marajó.
Mompox or Mompós, officially Santa Cruz de Mompox, is a town and municipality in northern Colombia, in the Bolívar Department. The town initially grew from its proximity to the Magdalena river and has preserved much of its colonial character. It also played an important role in the liberation of South America from Spain. Today, Mompox depends upon tourism, fishing, and some commerce generated by the local cattle raising. The municipality has a population of 46,408 and is adjacent to the municipalities of Pinillos and San Fernando. The historic center of Mompox was made a UNESCO World Heritage Site in 1995, owing to its preserved colonial architecture and mixture of architectural styles.
River bifurcation occurs when a river flowing in a single channel separates into two or more separate streams which then continue downstream. Some rivers form complex networks of distributaries, typically in their deltas. If the streams eventually merge again or empty into the same body of water, then the bifurcation forms a river island.
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.
Channel patterns are found in rivers, streams, and other bodies of water that transport water from one place to another. Systems of branching river channels dissect most of the sub-aerial landscape, each in a valley proportioned to its size. Whether formed by chance or necessity, by headward erosion or downslope convergence, whether inherited or newly formed. Depending on different geological factors such as weathering, erosion, depositional environment, and sediment type, different types of channel patterns can form.
The Villa de Santa Cruz de Mompox was founded by Don Juan Quintero de Heredia, Adelantado of the Gobernation of Cartagena and brother of the founder of that city, Pedro de Heredia, on May 3, 1537, after fighting battles against the Kimbay tribe and defeating the Chieftain Mompoj.
