The message about the Congo River in Africa is brief. Congo - a river in the heart of Africa
Congo (Zaire, Lualaba) - river in Central Africa, mainly in the Democratic Republic of the Congo (partially flows along its borders with the Republic of the Congo and Angola), the deepest and second longest river in Africa, the second most water-rich river in the world after the Amazon. In the upper reaches (above the city of Kisangani) it is called Lualaba. The only major river that crosses the equator twice. The basin area is 4,014,500 km.
It originates from the settlement of Mumena.
Geography
River basin
The length of the Congo from the source of Chambeshi is over 4,700 km, from the source of Lualaba - 4,374 km. The basin area is 4,014,500 km. The source of the Lualaba originates in the southeast of the DRC, on a plateau near the border with Zambia. According to other sources, the source of the Congo is the Chambeshi River, which forms between lakes Nyasa and Tanganyika at an altitude of 1590 meters above sea level. It flows into Lake Bangweulu, flows out of it as Luapula, flows into Lake Mweru, flows out of it as the Luvua River and joins Lualaba. The upper reaches of the Congo (Lualaba), located within plateaus and plateaus, are characterized by alternating rapids and leveled pools with a calm current. The steepest drop (475 m at a distance of about 70 km) of Lualaba is in the Nzilo Gorge, with which it cuts through the southern spurs of the Mitumba Mountains. Starting from the city of Bukama, the river flows slowly, meandering strongly, along flat bottom Upemba graben. Below the city of Kongolo, Lualaba breaks through crystalline rocks with the Port d'Anfer (Hell's Gate) gorge, forming rapids and waterfalls; further downstream, several more groups of waterfalls and rapids follow one after another. Between the cities of Kindu and Ubundu the river flows calmly again in a wide valley. Just below the equator, it descends from the edges of the plateau into the Congo Basin, forming the Stanley Falls.
After Stanley Falls near the city of Kisangani, the river changes its name to Congo. In the middle course, contained within the Congo Basin, the river is calm with a slight fall (on average about 0.07 m/km). Its channel, predominantly with low and flat, often swampy banks, is a chain of lake-like extensions (in some places up to 15 km), separated by relatively narrowed (up to 1.5-2 km) sections. In the central part of the Congo Basin, the floodplains of the river and its right tributaries Ubangi and Sanga merge together, forming one of the largest periodically flooded areas in the world. As we get closer to western edge In the depression, the appearance of the river changes: it is compressed here between high (100 m or more) and steep bedrock banks, narrowing in places to less than 1 km; depths increase (often up to 20 - 30 m), the current accelerates. This narrowed section, the so-called Channel, passes into the lake-like expansion of Stanley Pool (about 30 km long, up to 25 km wide), which ends the middle course of the Congo.
IN downstream The Congo breaks through to the ocean through the South Guinea Plateau in a deep (up to 500 m) gorge. The width of the channel here decreases to 400-500 m, in places to 220-250 m. Over the course of 350 km between the cities of Kinshasa and Matadi, the river descends 270 m, forming about 70 rapids and waterfalls, united under common name Livingston Falls. The depths in this area are 230 m or more, making the Congo the most deep river in the world. At Matadi, the Congo enters the coastal lowland, the channel widens to 1-2 km, the depths in the fairway reach 25-30 m. Near the city of Boma, the Congo estuary begins, the width of which in the middle part reaches 19 km, then decreases to 3.5 km and increases again towards the mouth, where it is 9.8 km. Top and middle part estuaries are occupied by an actively forming young delta. The continuation of the estuary is the Congo underwater canyon with a total length of at least 800 km.
Tributaries
The most significant tributaries of the Congo
- upper reaches: on the right - Lufira, Louvois, Lukuga; in the middle reaches: on the left - Lomami, Lulongo, Ruki, Kasai (the largest of the left tributaries), on the right - Aruvimi, Itimbiri, Mongala, Ubangi (the largest major influx Congo), Sanga; in the lower reaches - Inkisi (left), Alima (right).
Several belong to the Congo system large lakes: Tanganyika and Kivu in the Lukuga River basin; Bangweulu and Mweru in the Luvua River basin; Mai-Ndombe in the Kasai River basin; Tumba (has a drainage directly into the Congo through the Ireba channel).
Hydrology
In the formation of river flow in the Congo Basin, the predominant role is played by abundant rain power. Most of the tributaries of the Congo are characterized by a predominance of autumn flow: in tributaries with catchments in the Northern Hemisphere, the maximum rise in water is observed in September-November, in the Southern Hemisphere - in April-May. The April-May maximum runoff is also typical for upper Congo(Lualabs). In the middle and, especially in the lower reaches of the Congo, seasonal fluctuations in flow are largely smoothed out due to the different times in which the flood waters of its tributaries enter the river; of all the great rivers globe Congo is characterized by the greatest natural regulation. IN annual progress level, however, two rises and two declines are clearly expressed. In the middle Congo, the rise in water corresponding to the autumn maximum flow of the Lualaba is shifted to May-June and is of a secondary nature, while the main rise occurs in November-December under the influence of floods on the northern tributaries. In the lower reaches of the Congo, the main rise also occurs in November-December; a less significant rise in April-May is mainly associated with the autumn maximum flow of the Kasai River. Average water flows in the lower reaches of the Congo (near Boma): annual - 39 thousand m?/sec, in the month of the highest water (December) - 60 thousand m?/sec, in the month of the lowest water (July) - 29 thousand .m?/sec; absolute extreme costs - from 23 to 75 thousand m?/sec. Average annual flow 1230 km (according to other sources, 1453 km). Huge masses of water carried by the Congo into the ocean desalinate it 75 km from the coast. The solid flow of the Congo in the estuary area is about 50 million tons per year.
Average monthly water flow in the river (m?/s) in the area of Kinshasa (480 km from the mouth) from 1903 to 1983
Economic use
Hydropower resources
Compared to other rivers in the world, the Congo has one of the largest hydropower reserves, estimated at 390 GW. The latter is explained big amount water carried by the river, and a significant drop in the bed along its entire length up to the mouth. Other large rivers in their lower reaches they are flat and flow in lowlands. Several large hydroelectric power stations have been built in the Congo - Nzila, Nseke (at Lualaba), Inga (at Livingston Falls). In total, about 40 hydroelectric power plants have been built in the Congo Basin.
The river's largest hydroelectric power station is Inga, located about 200 km southwest of Kinshasa. The Inga project was launched in the early 1970s with the construction of the first dam. To date, only two dams have been built, “Inga I” (French Barrage Inga I) and “Inga II” (French Barrage Inga II), which operate fourteen turbines. The projects "Inga III" (French: Barrage Inga III) and "Grand Inga" (French: Barrage Grand Inga, English: Grand Inga Dam) are at the design stage. If the Grand Inga project is implemented, its capacity will be more than double that of the Three Gorges hydroelectric station in China. There are concerns that the construction of these new dams could lead to the extinction of many fish species that are endemic to the river.
Shipping
The total length of shipping routes along the rivers and lakes of the Congo Basin is about 20 thousand km. Most of the river sections accessible for navigation are concentrated in the Congo Basin, where they form a single branched system waterways, which, however, is separated from the ocean by the Livingston Falls in the lower Congo. The river itself has 4 main navigable sections: Bukama - Kongolo (645 km), Kindu - Ubundu (300 km), Kisangani - Kinshasa (1742 km), Matadi - mouth (138 km); the last section, the so-called offshore pool, is accessible to ocean-going vessels. Navigable areas of the Congo are interconnected railways. The main river and lake ports in the Congo basin: in the Congo - Kinshasa, Brazzaville, Mbandaka, Kisangani, Ubundu, Kindu, Kongolo, Kabalo, Bukama; on the Ubangi River - Bangui; on the Kasai River - Ilebo; on Lake Tanganyika - Kalima, Kigoma, Bujumbura; on Lake Kivu - Bukavu. In the lower reaches of the Congo there are the seaports of Matadi, Boma, Banana.
Fishing
The rivers and lakes of the Congo Basin are rich in fish (about 1000 species, many of which are of commercial importance: Nile perch, tilapia, barbel, large tiger fish, freshwater herring and others).
Cities on the river
The most important cities in Congo:
Bukama
Bukama (beginning of navigation) is a city in the Democratic Republic of the Congo (Katanga province), a river pier in the upper reaches of the Lualaba River, railroad station on the Lubumbashi - Ilebo line.

Port in Kisangani
Kisangani (before 1966 - Stanleyville) is a city in northeastern Congo, administrative center Tshopo Province. In 2010 the population was 868,672 people. Port on the Congo River below Stanley Falls. The city has a train station, a university and international Airport. Founded by the famous traveler, explorer of Africa and journalist Henry Stanley in 1883 and was originally called Stanleyville. Modern Kisangani is the center of an agricultural region where primary processing of agricultural raw materials (rice and cotton ginning) is carried out. In addition, there are food, textile, chemical industry, woodworking, and also the production of building materials.
Kinshasa
Kinshasa (until 1966 - Leopoldville) - capital (since 1960) Democratic Republic Congo, located on the Congo River, opposite the city of Brazzaville, the capital of the Republic of the Congo. Although the city's population in 2009 was 10,076,099 people, 60% of its territory is sparsely populated countryside, which, nevertheless, entered the administrative boundaries of the city. Densely populated urban areas occupy only a small part of the territory in the west of the province.
Matadi
Matadi (meaning “stone” in the language of the Congo people (Kikongo)) is the main seaport of the Democratic Republic of the Congo and the center of the province Central Congo(former province of Bas-Congo). Matadi was founded in 1879 by Henry Morton Stanley. The city is located on the left bank of the Congo River, 148 kilometers from the mouth. In 2004 the population was 245,862.

Brazzaville (French Brazzaville) is the financial and administrative capital and the most densely populated city Republic of the Congo, located on the right bank of the Congo River, opposite Kinshasa. The population as of 2010 is 1,252,974 people. Brazzaville is home to a third of the population of the Republic of Congo and employs about 40% of people employed in non-agricultural industries.
History of discovery and research
In late 1481, King João II of Portugal sent a fleet of caravels along the west coast of Africa to the Gold Coast (modern Ghana) to open gold mines there. The expedition was led by Diogo de Azambuja. Slaves were needed for the mine, so in 1482 Azambuja sent Diogo Cana to explore the then unknown West Coast Africa. Around 6° south latitude The Portuguese discovered the mouth big river and landed on the shore, where they were met by black people of the Bantu tribe. They said that the river is called Nzari - “Big”, and the state through whose territory it flows is ruled by a king bearing the title Mani-Kongo (English) Russian. As a sign of the discovery of these lands, the Portuguese erected a padran (stone pillar) not far from the mouth ), and the river was named the Padrau River (Rio do Padrao).
Upstream Congo (Lualaba) was discovered by David Livingstone in 1871. Most of the Congo from Niangwe downstream was explored in 1876-1877 by Henry Stanley. The Kassai tributary was explored by Wissmann in 1885.
Attractions
The most famous waterfalls on the river are the seven-stage Stanley (Boyoma) in the upper reaches of the Congo, Inga in its middle reaches, and the cascade of Livingston waterfalls in the lower reaches.
The answer to the question in which direction the Congo River flows should be looked for in the center African continent. This watercourse is the first on the mainland in terms of full flow and the second in length. In the world, only the Amazon has a greater flow. The Congo was discovered by the Portuguese navigator D. Kahn in 1482. This unique river differs from other great watercourses in that it crosses the equator twice.
Current direction
In which direction does it flow? Starting from the source, it rushes towards the north. The middle course of the river has western direction. The last stretch of the path of Africa's largest watercourse runs towards the southwest.
Source of the river Congo is located on a high plateau located in the south of the African continent. The river flows towards the north until it reaches the equator. The aborigines named this section of the river Lualaba. In the equator region of the Congo, Stanley falls in the form of 7 waterfalls from a height of 40 meters. This point is the beginning of the middle course of the river, already known as the Congo. Among tropical forests the watercourse describes a huge arc, gradually changing direction: northwest, west, southwest.
Description of the river
It is impossible to answer the question in which direction the Congo River flows. It is necessary to clarify a specific area or list several cardinal directions. The length of the watercourse is 4700 km. The river basin covers an area of 3.68 million km 2. The channel of the Congo is located on the territory of two countries, and ends in the Atlantic Ocean.
1600 km of the watercourse from its confluence with the ocean are passable for ships. Water flow at the mouth varies from 23 to 75 thousand m 3 /sec. In this place, the river’s width is maximum and is 11 km, and its depth is up to 300 m.
River mode
The Congo is uniform, which distinguishes it from other rivers of the tropics. The reason lies in the fact that rain does not fall in different parts of the basin at the same time. While there is drought in the northern hemisphere, there is drought in the southern hemisphere. heavy rains, and vice versa. They balance the flow of water into the riverbed because the Congo is on both sides of the equator. Throughout the course there are many waterfalls and rapids.
River flow
After the confluence of Chambeshi and Lualaba, the watercourse takes on a calm appearance up to the city of Kongolo. Having passed the city, the riverbed passes through the rocks along a gorge, where it abounds with waterfalls and rapids. The river changes from savannah to tropical forest. After the town of Kindu, the Congo reaches a width of 1.5 km, the flow of the stream is quiet. Full-flowing tributaries form sandbanks in the channel.
Gradually, the Congo River reaches the edge of the plateau and cascades down the Stanley Falls. There are seven of them on a 150-kilometer stretch. The most picturesque is the last of them, which is divided into two parts by the island. Its height is about 3 m, but it produces a lot of foam as it passes at breakneck speed through the narrow crevices between the shores and the island.
In the depression, the direction of the Congo River changes smoothly, resembling an arc. The current becomes uniform, but strong. After entering the flat area, the river externally becomes like a cascade of lakes. In fact, this is a chain of pools (extensions). The width varies from 4 to 15 km. Moving further downstream of the Congo, you will notice that the banks become flatter.
On both sides of the river there are swampy places that are flooded even with a slight increase in water level. Starting from the town of Bolobo, the banks become higher, and the Congo enters the territory of savannas. The river valley becomes deeper and narrower. Soon the watercourse will form a system. On its way to the ocean, this waterway will undergo several more transformations. Answering the question in which direction the Congo River flows, one can list several of its sections, indicating the cardinal directions to which it carries its waters.
The majority of Congo rivers are not very long and the local “queen”, of course, is the Congo River. Other rivers of the republic are much shorter and are most often its tributaries.
Congo
Congo – main river throughout Central Africa. Estuary water artery was opened in 1482. The person who first entered the waters of the Congo was the Portuguese Dien Kar. His main activity was trade, and the river was just an assistant in establishing commercial relations with the Kingdom of Kongo. By the way, the basis of the entire economy at that time was the slave trade. The upper course of the river was studied only in 1871.
There is still some disagreement about the source of the river: some geographers believe that the Lualaba River gave rise to the Congo; others are sure that the source is the Chambesi River.
The Congo is the only river in the world that crosses the equator twice. And that is why the level of local waters is kept at the same level throughout the year. Congo Basin - place of growth equatorial forests. Thanks to high humidity representatives of the local flora, such as ebony and mahogany, as well as oaks, can reach a height of 60 meters.
Attractions:
- Livingston Falls, located near the city of Kinshasa;
- Stanley Falls;
- National parks;
- city of Kinshasa.
Aruvimi
Aruvimi is one of the major tributaries of the Congo, total length 1300 kilometers. The river originates in the Blue Mountains, west of Lake Albert.
The river is suitable for travel only in its lower reaches, since there are many waterfalls and rapids upstream. G. Stanley became a researcher of the Aruvimi channel.
Ubangi
The Ubangi is the largest tributary of the Congo. The river is navigable throughout the year, starting from the city of Bangui, and right up to its confluence with the Congo. The rights of the pioneer explorer of its basin belong to the German botanist Georg August Schweinfurt.
In the waters of Ubangi you can find elephant fish. The length of the fish is relatively small (up to 35 cm), but it received this name because of its long lower lip, somewhat reminiscent of an elephant’s trunk. For orientation in muddy river water fish use electrical organs located at the end of their tail.
The river basin is a place known to all diamond miners. And, since the Congolese government is unable to control illegal mining, a huge number of stones are exported from here illegally.
Attractions:
- waterfalls (Gozbangi, Ngolo, Elefan, Buali) and Azande rapids;
- city of Bangui;
- Zemongo Nature Reserve.
The Congo River is a deep stream flowing through the central and southern regions Africa. It crosses the equator twice and flows into the waters of the Atlantic Ocean. The length of the river is 4700 km. This is 9th place in the world. By size water flow the river ranks 3rd in the world after the Amazon and Ganges. It discharges an average of 41 thousand cubic meters into the waters of the Atlantic. m/s. Square water basin is 4 million 14.5 thousand square meters. km. This is the 2nd place in the world after the Amazon. But in terms of depth, Congo is in 1st place. In some places the depth reaches 230 meters. This water stream is considered the second in Africa, second only to the Nile River.
Regarding the length of the great African river, then there is no consensus among geographers. Some of them consider the source to be from the Lualaba River. Thus, the total length is only 4374 km. Another part of the experts insists on the source of the Chambesi River, which originates near Lake Tanganyika. It is Congo-Chambezi that is equal to 4700 km. According to generally accepted world practice, the latter value is more true, since the longest source is always taken.
Congo River
Chambesi River flows through northeastern Zambia. It originates at an altitude of 1760 meters above sea level. Its path passes through the Bangveulu swamps. Lake Bangweulu is part of them. Then the river turns towards Lake Mveri, flows into it and flows out as the Luvois River. It is the latter that flows into the Lualaba River.
Lualaba River begins its journey on the Katanga plateau at an altitude of 1400 meters above sea level in Zambia. It crosses the Ternopil plateau and is replete with waterfalls and rapids. Taking this into account, there are hydroelectric power stations on the river. In the city of Bukama, located at the same latitude as Lake Mveri, Lualaba becomes navigable. In the area of the city of Ankoro, the Louvois River flows into this water stream.
Lualaba was once considered the source of the Nile, but this turned out not to be the case. The water flow does not turn to the east, but carries its waters to the north. At the same time, in its lower course it overcomes rapids and forms numerous waterfalls. The last cascade of waterfalls is called Stanley. After it, the river turns west and near the city of Kisangani changes its name to Congo.
Further, the water flow flows through the flat terrain, which is a plateau at an altitude of 400-500 meters above sea level. In this place the current is calm. Narrow areas alternate with small lakes. The shores are mostly swampy. Next, the Congo River reunites with its right tributaries: the Ubanga and Sanga rivers. The way forward passes between steep banks. The channel is compressed and the depth increases. Accordingly, the flow accelerates.
Finally the water flow leaves behind the high rocky shores and spreads wide. A small lake, Molebo Pool, is formed. Its length reaches 30 km and width 20 km. Then the series of gorges begins again. Granite rocks hang over the water surface at an altitude of up to 500 meters. The width of the water flow decreases to 400 meters, but the depth increases to 200-230 meters. After the city of Kinshasa, the river waters flow down, losing 270 meters of height. These are continuous waterfalls and rapids, united under the general name of Livingston Falls.
Congo River on the map
148 km from the mouth is the city of Matadi, and the turn of the coastal lowlands begins. The river bed expands to 2 km, and the depth reaches 30 meters. The mouth is estuary. That is, the river flows in a continuous stream, and does not break up into channels and branches. The width of the estuary ranges from 19 to 9 km. It turns into an underwater canyon, the length of which reaches 800 km. Thus, the great African river flows into the Atlantic, connecting the ocean with the regions of Central Africa.
The Congo River flows primarily through the Democratic Republic of the Congo. Also along the river passes state border with the Republic of Congo and Angola. The river basin is located in tropical forests. Their area is the second largest after the Amazon. Good connection between Kinshasa and Kisangani shipping is developed. But it has no connection with the ocean because of Livingston Falls. In fact, the river has several navigable sections, isolated from each other. They are connected to each other by railways. This creates certain inconveniences when transporting goods.
There are many cities on the river. You can name Kinda with a population of 135 thousand inhabitants. Kisangani with a population of almost 900 thousand inhabitants. This city has a large river port. But Kinshasa is the capital of the DRC. It is a densely populated area with a population of 10 million people. On the right bank, opposite Kinshasa, is the capital of the Republic of Kazakhstan, Brazzaville, with a population of about 1.3 million people. Matadi is home to 246 thousand inhabitants. And in the city of Banana, which is considered a seaport, there are 10 thousand inhabitants.
To date, about 40 hydroelectric power stations have been built in the basin of the great African river. The largest of them are located at the Inga Falls. It belongs to the Livingstone Falls and is located 200 km southwest of Kinshasa. According to the plan, there should be 5 dams in this place. But to date only two have been built. These are Inga and Inga II. Together they have 14 turbines. But these are only the first steps, since the Congo Basin has enormous energy potential.

Congo River(or Zaire) – big river in Central Africa. Most of The channel is located in the territory of the Democratic Republic of Cong. The river is natural boundary between the DCR and the Republic of the Congo, as well as the DCR and Angola. This is the deepest and second (after the Nile) longest river on the mainland. In terms of flow, the Congo is not inferior to any other river in the world except the Amazon. Another similarity between the Amazon and the Congo is found here scary fish(monster of the Congo River), which is probably second only to piranha in terms of bloodthirstiness. Among other things, the Congo is the only large river that crosses the equator twice.
The river has been known to Europeans since ancient times. It was discovered in 1482 by the Portuguese navigator Diogo Can.
Length: 4,700 km.
Drainage basin area: 3,680,000 sq. km.
Where does it occur: The Congo originates at an altitude of 1600 meters above sea level, between lakes Niassa and Tanganyika in Zambia. According to other sources, the source is located on the Shaba plateau in the DKR, near the border with Zambia to the west of the city of Kolwezi. Up to Stanley Falls (near the city of Kisangani) the river is called Lualaba, further down the river it is already called Congo.
In the middle reaches, the mountainous terrain gives way to flat terrain and the river overflows, forming a wide valley with a large number of channels and lakes. The width of the valley in some places reaches 20 km.
In its lower reaches, the river is blocked by the South Guinea Upland, and the river is squeezed into a deep narrow gorge, the width of which in some places reaches 300 meters. The depth of the river in some places is 230 m and even more. This makes the Congo the deepest river in the world. The total fall in this area is 270 m. In this area there is a large number of rapids and rapids which are called Livingston Falls. The mouth of the river is located at the city of Banana, where the Congo flows into the Atlantic Ocean, forming an estuary.
The Congo River really unusual river. She has greatest potential For economic use in hydropower among all the rivers in the world. This is explained both by the full flow of the river and the large drop in the riverbed throughout its entire course. Unlike the Congo, other large rivers in the lower reaches are flat. Total stock hydropower is estimated at 390 GW. Livingston Falls alone contains approximately ~113.4 GW or ~994 TWh of electricity per year. To appreciate this figure, it is worth saying that in 2007, the generation of all power plants in Russia (including thermal, nuclear, hydro...) amounted to 997.3 TWh. But the problem is to curb this power. In 2014, construction of the Grand Inga hydroelectric power station with a capacity of 39.6 GW is expected to begin. The construction cost is estimated at $80 billion. Grand Inga will be 2 times larger than the most powerful this moment the Three Gorges hydroelectric power station in China, and more than 100 times the Kakhovskaya hydroelectric power station with a capacity of 351 MW.
Water flow at the mouth can vary from 23,000 m³/sec to 75,000 m³/sec depending on the season and averages 46,000 m³/sec. The average annual flow is 1450 km 3 . Solid drainage is about 50 million tons per year. The river is also relatively smooth water regime, which is caused by intermittent rainy seasons in different parts of the river basin. The ocean in the area of the mouth is desalinated over a distance of 76 km. from the shore.
Main tributaries: Ubangi, Sangi, Kassai (Kwa). The river basin also includes the following: big lakes: Tanganyika, Kivu, Mweru, Tumba, Bangweulu...
