Mongala is one of the 21 provinces of the Democratic Republic of the Congo created in the 2015 repartitioning . Mongala, Équateur , Nord-Ubangi , Sud-Ubangi , and Tshuapa provinces are the result of the dismemberment of the former Équateur province. Mongala was formed from the Mongala District whose town of Lisala was elevated to capital city of the new province.

27-468: Mongala is located at the northwest of the country on the Congo River , and borders the provinces of Tshopo , Bas-Uele, Nord-Ubangi, Sud-Ubangi, Équateur and Tshuapa. It is divided into three territories: The province includes the village of Yambuku . From 1963–1966, Mongala Province was known as Moyen-Congo . However, under Mobutu, the province was reintegrated into the former Équateur province where it

54-420: A river , is the portion of its sediment uplifted by the fluid's flow in the process of sediment transportation . It is kept suspended by the fluid's turbulence . The suspended load generally consists of smaller particles, like clay , silt , and fine sands . The suspended load is one of the three layers of the fluvial sediment transportation system. The bed load consists of the larger sediment which

81-405: A proposal to expand generation through improvements and the construction of a new hydroelectric dam . The project would bring the maximum output of the facility to 40,000 megawatts (MW). It is feared that these new hydroelectric dams could lead to the extinction of many of the fish species that are native to the river. Suspended sediment The suspended load of a flow of fluid , such as

108-522: Is carried within the lower to middle part of the water column and moves at a large fraction of the mean flow velocity of the stream, with a Rouse number between 0.8 and 1.2. The rates within the Rouse number reveal how at which the sediment will transport at the current velocity. It is the ratio of the fall velocity and uplift velocity on a grain. Suspended load is often visualised using two diagrams. The Hjulström curve uses velocity and sediment size to compare

189-421: Is transported by saltation , rolling, and dragging on the riverbed . The suspended load is the middle layer that consists of the smaller sediment that's suspended. The wash load is uppermost layer which consist of the smallest sediment that can be seen with the naked eye; however, the wash load gets easily mixed with suspended load during transportation due to the very similar process. The wash load never touches

216-661: The Atlantic Ocean and an additional 6% of bedload . The river and its tributaries flow through the Congo rainforest , the second largest rainforest area in the world, after the Amazon rainforest in South America. The river also has the second-largest flow in the world, behind the Amazon ; the second-largest drainage basin of any river, behind the Amazon; and is one of the deepest rivers in

243-560: The Inga dams , about 200 kilometres (120 mi) southwest of Kinshasa. The project was launched in the early 1970s, when the first dam was completed. The plan (as originally conceived) called for the construction of five dams that would have had a total generating capacity of 34,500 megawatts (MW). To date only the Inga I and Inga II dams have been built, generating 1,776 MW. In February 2005, South Africa 's state-owned power company, Eskom , announced

270-576: The Lualaba River , and Lualaba is the name of the Congo River upstream of Boyoma Falls , extending for 1,800 km (1,100 mi). Measured along with the Lualaba, the main tributary, the Congo River has a total length of 4,370 km (2,720 mi). It is the only major river to cross the Equator twice. The Congo Basin has a total area of about 4,000,000 km (1,500,000 sq mi), or 13% of

297-560: The Pool Malebo (Stanley Pool). Kinshasa (formerly Léopoldville) and Brazzaville are on opposite sides of the river at the Pool, where the river narrows and falls through a number of cataracts in deep canyons (collectively known as the Livingstone Falls ), running by Matadi and Boma , and into the sea at Muanda . Lower Congo constitutes the "lower" parts of the great river; that is

324-506: The Uíge Province in Angola to the confluence with the Congo at Zongo some 80 km (50 mi) downstream from the twin capitals. Because of the vast number of rapids, in particular the Livingstone Falls , this section of the river is not operated continuously by riverboats. The Congo basin covers ten countries and accounts for about 13% of Africa . The highest point in the Congo basin

351-520: The Atlantic Ocean. Opportunities for the Congo River and its tributaries to generate hydropower are therefore enormous. Scientists have calculated that the entire Congo Basin accounts for 13 percent of global hydropower potential. This would provide sufficient power for all of Sub-Saharan Africa 's electricity needs. Currently, there are about 40 hydropower plants in the Congo Basin. The largest are

378-624: The Congo below Boyoma Falls . The Chambeshi River in Zambia is generally taken as the source of the Congo in line with the accepted practice worldwide of using the longest tributary, as with the Nile River. The Congo flows generally toward the northwest from Kisangani just below the Boyoma Falls, then gradually bends southwestward, passing by Mbandaka , joining with the Ubangi River and running into

405-454: The bed even outside of a current. The boundary between bed load and suspended load is not straightforward because whether a particle is in suspension or not depends on the flow velocity – it is easy to imagine a particle moving between bed load, part-suspension and full suspension in a fluid with variable flow. Suspended load generally consists of fine sand, silt and clay size particles although larger particles (coarser sands) may be carried in

432-508: The entire African landmass. The name Congo/Kongo originates from the Kingdom of Kongo once located on the southern bank of the river. The kingdom in turn was named after the indigenous Bantu Kongo people , known in the 17th century as "Esikongo". South of the Kingdom of Kongo proper lay the similarly named Kakongo kingdom, mentioned in 1535. Abraham Ortelius labelled "Manicongo" as the city at

459-523: The lower water column in more intense flows. Suspended load and suspended sediment are very similar, but are not the same. Suspended Sediment contains sediment uplifted in Fluvial zones, but unlike suspended load no turbulence is required to keep it uplifted. Suspended loads required the Velocity to keep the sediment transporting above the bed. With low velocity the sediment will deposit. The suspended load

486-597: The mouth heading upstream): Lower Congo (river mouth to Kinshasa ) Downstream of Kinshasa, from the river mouth at Banana , there are a few major tributaries. Middle Congo ( Kinshasa to the Boyoma Falls ) Upper Congo ( Lualaba ; upstream from the Boyoma Falls ) Although the Livingstone Falls prevent access from the sea, nearly the entire Congo above them is readily navigable in sections, especially between Kinshasa and Kisangani. Large river steamers worked

513-504: The mouth of the river in his world map of 1564. The tribal names in Kongo possibly derive from a word for a public gathering or tribal assembly. The modern name of the Kongo people or Bakongo was introduced in the early 20th century. The name Zaire is from a Portuguese adaptation of a Kikongo word, nzere ("river"), a truncation of nzadi o nzere ("river swallowing rivers"). The river

540-574: The rate of erosion, transportation, and deposition. While the diagram shows the rate, one flaw about the Hjulström Diagram is that it doesn't show the depth of the creek giving an estimated rate. The second diagram used is the Shields Diagram. The Shields Diagram (based on the Shields formula ) uses the critical shear stress and Reynolds number to estimate transportation rate. The Shields Diagram

567-506: The river until quite recently. The Congo River still is a lifeline in a land with few roads or railways. Railways now bypass the three major falls, and much of the trade of Central Africa passes along the river, including copper , palm oil (as kernels), sugar , coffee , and cotton . The Congo River is the most powerful river in Africa. During the rainy season over 50,000 cubic metres (1,800,000 cu ft) of water per second flows into

594-576: The section of the river from the river mouth at the Atlantic coast to the twin capitals of Brazzaville and Kinshasa. In this section of the river, there are two significant tributaries, both on the left or south side. The Kwilu River originates in the hills near the Angolan border and enters the Congo some 100 km upstream from Matadi . The other is the Inkisi River , that flows in a northerly direction from

621-406: The third-largest river in the world by discharge volume, following the Amazon and Ganges rivers. It is the world's deepest recorded river, with measured depths of around 220 m (720 ft). The Congo– Lualaba – Luvua – Luapula – Chambeshi River system has an overall length of 4,700 km (2,900 mi), which makes it the world's ninth- longest river . The Chambeshi is a tributary of

648-491: The world, at depths greater than 220 m (720 ft). Because its drainage basin includes areas both north and south of the Equator , its flow is stable, as there is always at least one part of the river experiencing a rainy season . The sources of the Congo are in the highlands and mountains of the East African Rift , as well as Lake Tanganyika and Lake Mweru , which feed the Lualaba River , which then becomes

702-507: Was known as Zaire during the 16th and 17th centuries; Congo seems to have replaced Zaire gradually in English usage during the 18th century, and Congo is the preferred English name in 19th-century literature, although references to Zahir or Zaire as the name used by the inhabitants remained common. The Democratic Republic of the Congo and the Republic of the Congo are named after it, as

729-774: Was the previous Republic of the Congo which had gained independence in 1960 from the Belgian Congo . The Republic of Zaire during 1971–1997 was also named after the river's name in French and Portuguese . The Congo's drainage basin covers 4,014,500 km (1,550,000 sq mi), an area nearly equal to that of the European Union . The Congo's discharge at its mouth ranges from 23,000 to 75,000 m /s (810,000 to 2,650,000 cu ft/s), with an average of 41,000 m /s (1,400,000 cu ft/s). The river transports annually 86 million tonnes of suspended sediment to
