Auati-Paraná Canal
The Auati-Paraná Canal () is a natural canal of Amazonas state in north-western Brazil. It is a distributary that leaves the Solimões River and joins the Japurá River. Course The Auati-Paraná, also called the Ati-Paraná or Ati-Paranã, is sometimes called a river, sometimes a ''paraná'' (channel) and sometimes a canal. The last term seems most appropriate, since the natural canal leaves one river and joins another. The canal divides the lower western Amazon plateau to the north from the Amazon plain. The canal forms the boundary between the Auatí-Paraná Extractive Reserve, created in 2001, on the north bank, and the Mamirauá Sustainable Development Reserve The Mamirauá Sustainable Development Reserve () in the Brazilian state of Amazonas (Brazilian state), Amazonas, near the city of Tefé, is a reserve near the village of Boca do Mamirauá. It includes mostly Amazon rainforest, Amazonian flooded f ... on the south bank. The canal is a body of white water, but almost ...

Solimões River
Solimões () is the name often given to upper stretches of the Amazon River in Brazil from its confluence with the Rio Negro upstream to the border of Peru. The Solimões flows for about 1,600 km (1,000 miles) through a floodplain about 80 km (50 miles) wide. Geography The Amazon / Solimões river just above the confluence of the Solimões and Rio Negro is already by far the largest river in the world, even though its two largest tributaries (the Negro and the Madeira River) have not yet contributed to the flow volume. The Solimões portion of the Amazon River lies entirely in the state of Amazonas, Brazil, and some portion of the state is often referred to as the "Solimões region". The ecoregion of the Solimões River drainage basin is entirely tropical rainforest. Etymology An Amazonian aboriginal nation called ''Soriman'' was corrupted in Portuguese to ''Solimão'' and ''Soliemoens'', from which the name of this section of the river and the region it drains is derived. ...

Japurá River
The Japurá River or Caquetá River is a long river in the Amazon basin. It rises in Colombia and flows eastward through Brazil to join the Amazon River. Course The river rises as the Caquetá River in the Andes in southwest Colombia. The Caquetá River rises near the sources of the Magdalena River, and augments its volume from many branches as it courses through Colombia. It flows southeast into Brazil, where it is called the Japurá. The Japurá enters the Amazon River through a network of channels. It is navigable by small boats in Brazil. West of the Rio Negro, the Solimões River (as the Amazon's upper Brazilian course is called) receives three more imposing streams from the northwest—the Japurá, the Içá (referred to as the Putumayo before it crosses over into Brazil), and the Napo. Brazilian Course On the border with Brazil, it meets the long Apaporis River (which is 1,370 km long when combined with one of its sources, the Tunia River), near the town of La Ped ...

Distributary
A distributary, or a distributary channel is a stream channel that branches off and flows a main stream channel. It is the opposite of a ''tributary'', a stream that flows another stream or river. Distributaries are a result of river bifurcation and 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. Related terms Common terms to name individual river distributaries in English-speaking countries are ''arm'' and ''channel''. These terms may refer to a distributary that does not rejoin the channel from which it has branched (e.g., the North, Middle, and South Arms of the Fraser River, or the West Channel of the Mackenzie River ...

Channel (geography)
In physical geography and hydrology, a channel is a landform on which a relatively narrow body of water is situated, such as a river, river delta or strait. While ''channel'' typically refers to a natural formation, the cognate term ''canal'' denotes a similar artificial structure. Channels are important for the functionality of ports and other bodies of water used for Navigability, navigability for shipping. Naturally, channels will change their depth and capacity due to erosion and Deposition (geology), deposition processes. Humans maintain navigable channels by dredging and other engineering processes. By extension, the term also applies to fluids other than water, e.g., lava channels. The term is also traditionally used to describe the Venusian channels, waterless surface features on Venus. Formation Channel initiation refers to the site on a mountain slope where water begins to flow between identifiable banks.Bierman, R. B, David R. Montgomery (2014). Key Concepts in Geom ...
