Clearwater River (river Type)
A clearwater river is classified based on its chemistry, sediments and water colour. Clearwater rivers have a low conductivity, relatively low levels of dissolved solids, typically have a neutral to slightly acidic pH and are very clear with a greenish colour. Clearwater rivers often have fast-flowing sections. The main clearwater rivers are South American and have their source in the Brazilian Plateau or the Guiana Shield. Outside South America the classification is not commonly used, but rivers with clearwater characteristics are found elsewhere. Amazonian rivers fall into three main categories: clearwater, blackwater and whitewater. This classification system was first proposed by Alfred Russel Wallace in 1853 based on water colour, but the types were more clearly defined according to chemistry and physics by from the 1950s to the 1980s. Although many Amazonian rivers fall clearly into one of these categories, others show a mix of characteristics and may vary depending ...

Ji-Paraná River
The Ji-Paraná River (Machado River), sometimes spelled Jiparaná, is a river in Rondônia state in western Brazil. It is a tributary of the Madeira River in the Amazon Basin. For much of its length it runs roughly parallel with the northeastern state border of Rondônia. The city of Ji-Paraná is divided by the river. Part of the river's basin is covered by the Jacundá National Forest, a sustainable use conservation unit. Part of the basin is in the Jaru Biological Reserve, a fully protected conservation unit created in 1984. The river forms the southern boundary in Rondônia of the Campos Amazônicos National Park, a protected area created in 2006 that holds an unusual enclave of cerrado vegetation in the Amazon rainforest.

Zambezi River
The Zambezi River (also spelled Zambeze and Zambesi) is the fourth-longest river in Africa, the longest east-flowing river in Africa and the largest flowing into the Indian Ocean from Africa. Its drainage basin covers , slightly less than half of the Nile's. The river rises in Zambia and flows through eastern Angola, along the north-eastern border of Namibia and the northern border of Botswana, then along the border between Zambia and Zimbabwe to Mozambique, where it crosses the country to empty into the Indian Ocean. The Zambezi's most noted feature is Victoria Falls. Its other falls include the Chavuma Falls at the border between Zambia and Angola, and Ngonye Falls near Sioma in western Zambia. The two main sources of hydroelectric power on the river are the Kariba Dam, which provides power to Zambia and Zimbabwe, and the Cahora Bassa Dam in Mozambique, which provides power to Mozambique and South Africa. Additionally, two smaller power stations are along the Zambezi R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Suriname River
The Suriname River ( Dutch: ''Surinamerivier'') is 480 km long and flows through the country Suriname. Its sources are located in the Guiana Highlands on the border between the Wilhelmina Mountains and the Eilerts de Haan Mountains (where it is known as the Gran Rio). The river flows below the reservoir along Brokopondo, Berg en Dal, the migrant communities Klaaskreek and Nieuw-Lombé, Jodensavanne, Carolina, Ornamibo and Domburg, before reaching the capital Paramaribo on the left bank and Meerzorg on the right bank. At Nieuw-Amsterdam it is joined by the Commewijne and immediately thereafter at the sandspit Braamspunt it flows into the Atlantic Ocean. The river has several sets of rapids as well as a few dams, the largest of which is the Afobaka Dam. The river's flow is interrupted by the Brokopondo Reservoir, which therefore divides the river into two sections. The upstream section runs almost entirely through the Sipaliwini district, and the downstream section ru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Araguari River (Amapá)
The Araguari River ( pt, Rio Araguari) is the primary river of Amapá state in north-eastern Brazil. It became famous among surfers when some decided to ride its constant tidal bore, characterizing waves that can last for several minutes. In 2013, three dams were built in the river to generate hydroelectricity. The dams ended the tidal bore which altered the flow of water in the Amazon, and caused significant land erosion and damage to the Bailique Archipelago. The river flows through the Uatuma-Trombetas moist forests ecoregion. The river defines the western boundary of the Amapá National Forest, a sustainable use conservation unit created in 1989.

Nhamundá River
Nhamundá River or Jamundá River (Yamundá River in Spanish) is a river in northern Brazil, which marks part of the northeastern boundary between states of Amazonas and Pará. The 300 km long Nhamundá River originates in the plateau '' Serra do Jatapu'' near the division of the Brazilian States of Roraima, Amazonas and Pará, and from there it flows in a southeastern direction, forming the natural division between Amazonas and Pará. It then crosses the Nhamundá-Mapuera Reserve (EG033) before joining the Trombetas River near the city of Oriximiná. The river, which flows through the Lago Nhamundá, is the last major right-hand affluent of the Trombetas River before the Trombetas joins the Amazon River. The mouth is located about 480 km east (downstream on the Amazon) of Manaus.

Guaviare River
The Guaviare is a tributary of the Orinoco in Colombia. It flows together with the upper Orinoco (until here also called Río Parágua), which it clearly surpasses in length (altogether about 1760 km) and water flow. Thus, the Guaviare is hydrologically the main stream of the Orinoco system. The Guaviare has its source in two other rivers, the Ariari and the Guayabero, which in turn have their own sources in the eastern part of the Andes. At long, it is the longest tributary of the Orinoco and is navigable for of its total length. The Guaviare is considered the border between the Llanos and the Amazon Rainforest The Amazon rainforest, Amazon jungle or ; es, Selva amazónica, , or usually ; french: Forêt amazonienne; nl, Amazoneregenwoud.
