The third longest river on the mainland. The largest, largest and longest rivers in the world. List

Thanks to the rivers melt or rainwater goes back to the ocean. Therefore, these watercourses can safely be called the main part of the water cycle on the planet. Each river system has a separate character, which depends on the climate, the relief of a particular area.

River length

When compiling the characteristics of rivers, the following factors are taken into account: length, water regime, flow, water content, width, and also the depth of the channel. First, the source is found, then the final place where it flows into the ocean or sea is determined, after which research is carried out throughout. In order to understand which river is the longest, it is necessary to correctly measure its size, which is sometimes not very easy. Determining the length between the mouth and the source is difficult due to the lack of accurate maps. Therefore, the measurements will directly depend on the scales used. The most objective option would be to measure the length on a small map, so it will be possible to show not only its size, but also the width of the stream. Despite the difficulties, scientists were still able to compile a list of the 5 longest rivers. However, after new expeditions, the results may change.

Yenisei - the fifth position in the list

One of the largest rivers in Russia is the Yenisei. It is approximately 5500 km long and 70 meters deep. She rightfully occupies the fifth position in the world list of "The Most long river planets." Thanks to her, the development of lands in the north of the country began several centuries ago. It is impossible not to note its importance for the state: the largest ports are located on the banks of the Yenisei, and the river itself is the navigable artery of the country. It flows in almost all geographical and climatic regions, serves as a border for the Eastern and Western Siberia. The river is replenishing different ways but mostly due to snowmelt. Typical floods in spring time of the year. Also, due to the formation of ice "plugs", the size of the river in some areas increases many times over. It should be noted that about 40 species of fish are found in the Yenisei: from crucian carp to sturgeon. It is not uncommon to see some birds nesting on the river. A serious problem for the Yenisei is the hydroelectric power station, after the construction of which the channels of the water flow have greatly decreased, as a result of which there is a significant threat to the flora and fauna of the river.

Longest river - Mississippi

Fourth place went to the river, which originates in the United States. Its significance for the world is very difficult to overestimate, it is rightfully the greatest in the world. The area of the Mississippi is slightly more than 3000 km, and together with the Missouri ( main tributary), this figure becomes twice as large - 6000 km. The Mississippi is almost the longest river on the continent, second only to the Amazon. Food varied: rain, mixed and snow. However, it is impossible to name the exact method of replenishing water for the entire river, since each region has different climatic conditions. It is characterized by high water in spring and summer. Also, often due to the melting of snow, severe floods form, which leads to floods. The Mississippi is a major and also the most important transportation artery of the United States of America, which paves the way from the mainland to the Gulf of Mexico. Small water streams flow into the river, which originate in the mountains and rocks. Another interesting fact is that the distance from the Great Lakes to the nearest bay is the Mississippi basin. The tributaries on the right side are in a dry climate, because of this, it is impossible to call the river full-flowing (even at the confluence with the Missouri). It becomes a major river only at the point of connection with the Ohio.

Third place on the list - Yangtze

In third place is the longest river in Eurasia - the Yangtze. Its total area is 6300 km. It, being a high-water river, flows throughout the territory of the Republic of China. Its waters are often used to irrigate fields. It should be noted that the Yangtze is the main highway of China. The stream is replenished with rainwater. The upper part of the river is fed by the melting of glaciers and snow. The river is also rich in fish. Its main inhabitants are carp, grass carp (black and white) and silver carp. The Yangtze is practically not covered with ice in winter time of the year. Freezing only those areas that are the most calm and are located only in upstream. An interesting fact is that in different regions the river is called differently. For example, in the Himalayas - Dangku, and in Tibet - Jichu. The Yangtze originates in Himalayan ice and flows through their gorges. Surprisingly, in a small area, the river drops sharply from a height of 5000 m to 1000 m. This makes it appearance the most attractive. In some areas, the Yangtze is expanding due to the many tributaries of lakes and rivers. It also built the world's largest hydroelectric power station, the Three Gorges.

African River Nile

In second place was the "blue vein" of Africa - the Nile. The longest river on Earth until the beginning of the 20th century. Its total length is 6800 km. The Nile has a sufficient number of tributaries, but the last 4 km before confluence with mediterranean sea the river flows without them. It should be noted that the river functional purpose has no analogues in the world. The inhabitants of Africa call this river sacred, a temple was erected in her honor and a holiday was arranged. The Nile is the longest river in the country, it is still worshiped by the Greeks, Arabs, Egyptians. Until the 19th century, this water flow completely determined the life of peoples. Due to certain factors, the level of the river could rise sharply many times over, flooding the valleys. After the decision to build dams, a human-controlled irrigation system appeared. Today, the Nile fully meets the needs of the country. It flows through different climatic zones, is divided into several branches and irrigates massifs (the so-called "black earth", formed several centuries ago). On the banks of the river you can always see tourists, fishermen, peasants and merchants.

The longest river on earth is the Amazon

The first place and absolute leadership belongs to the Amazon. It is located in South America, is the largest not only in length, but also in terms of the size of the basin, as well as in terms of full flow. The river is fed mainly by rain and groundwater. Snow and glacier nutrition is absent. In 2011, she entered the list of wonders of the world. It is surrounded on all sides by forests. various types: white, black and dry. Since the Amazon is the longest river, you can find many different fish and reptiles in it: piranhas, crocodiles, archers, caimans, mammals, fish, rays, etc. Its characteristic feature is that it often rises several meters, flooding large territories. The flora is quite rich, with more than 3,000 species.

Disputes of hydrologists

Deciding which is the longest peace river, scientists are in constant dispute. Until the beginning of the 20th century, many were convinced that Neil was the leader. However, after discovering starting point Amazons in the south of Peru (previously it was believed that the source is located in the north of the country), Brazilian scientists found that the total length of the Nile is 100-150 m less. During the study, special lighthouses were installed, which made it possible to carry out additional calculations. The final result was announced in 2015 and confirmed the accuracy of the preliminary findings. And if we take into account all the ramifications of the Amazon tributaries, then its length will reach about 7000 km. It is rightfully called the most full-flowing and longest river.

The Amazon is the longest river in the world by volume. Its waters carry a fifth of the total reserves throughout the entire South American continent. fresh water. The Amazon itself originates from the mixing of two rivers - Marañon and Ucayali in mountain range Andes in the state of Peru. The river ends its journey in Brazil, flowing into the Atlantic, changing its color and composition with its waters. ocean waters in the area up to 320 km. The very length of the River, based on the data of various scientific expeditions, is approximately 6259 - 6900 kilometers.

For a long time, the Amazon was recognized by scientists as the most full-flowing on the planet, but the African Nile surpassed it in length by about 300 kilometers. This opinion was a priority until the source of the river was found in the mountains of southern Peru. The data obtained during the study of the river allowed us to conclude that with the length of the Nile at 6,695 kilometers, from the source of the Ucayali, the length of the Amazon is 7,000 kilometers.

The volumes of water in the river are so great that even in particularly dry periods, the Amazon is 11 kilometers wide, while leaving more than 110 square kilometers of land under water. Accordingly, during the rainy season, the river increases in size by about 3 times, flooding the surface on a scale of almost 350 square kilometers of land. The mouth of the river itself is also impressive, being about 323 kilometers long, allowing it to be navigable by about 65%. Such large volumes of water in the river are natural because the Amazon's motion vector almost completely coincides with the equator and the reservoir itself is in fact almost all year round is in flood condition.

Due to the low level land in the area where the river flows into the Atlantic, during the ocean tides, a “poroka” can form (translated from Indian - “incredible noise”, “thundering water”). This is the result of the meeting of the waters of a mighty river with an ocean wave, during which a huge water shaft is formed, which rolls back to the movement of the river, crushing and breaking everything in its path. This phenomenon is so destructive in its power that it is capable of capsizing a ship. The wave reaches more than 4 meters in height and does not subside for more than half an hour, which allows it to devastate the surroundings in the region of 13 kilometers upstream of the river, at a speed of up to 25 km/h. The original inhabitants of the shores of the Amazon themselves personify vice with a merciless and cruel animal, as well as with the spirit of the great river, designed to protect it.

The very origin of the name of the river has two hypotheses. According to many, the Spanish conquistador Francisco de Orellano called the Amazons, who fought with the Jagua Indians and mistook them for women, since they had long hair and wore skirts. However, according to another theory, the name was formed from the Native American amassona (in the lane "destroyer of the boat").

The significance of the river for the planet is enormous, not only because of the huge reserves of fresh water, but also because of the almost unexplored world of flora and fauna living in the Amazon.

A huge number of plants found only in South America, grows on the banks of the Amazon. Also, more than 1800 species of birds, 1500 species of fish, about 250 different animals live here. The river waters are home to unique living creatures, such as piranhas, river sharks, arapaima (the largest freshwater fish) or Boto (pink dolphin).

Describing animal world Amazons, you can not ignore the water boa, which is better known as Anaconda. The snake itself reaches a length of 20 meters and is able to swallow a pig at a time - a baker, a person or even a jaguar.

diversity flora The Amazon River impresses with its forms and uniqueness.

A variety of trees, shrubs, palm trees with unusual and rare wood. For example, cinchona or hevea, which are especially valued for their bark and are the most the best sources rubber in the world. Also on the surface of the river, the largest water lily on the planet, called Victoria Regia, sways, the leaf of which resembles a large frying pan in shape and is able to hold a teenager on itself.

Often on the surface of the river you can find floating islands that slowly float with the flow. They are formed from trees that have fallen into the water, which are entwined with plants.

Rivers- natural watercourses that are part of the hydrological cycle. There are many unique reservoirs on our planet that can change course, dry up seasonally and supply drinking water huge population. What do you think, what size can surprise the largest and longest rivers in the world? We will consider the deepest, longest, largest water streams, but keep in mind that rivers tend to dry up and change their dimensions. We present to your attention the ranking based on the latest valid data of 2017.

Top 10 largest and longest rivers in our world

10. Niger. 4180 km

Opens the rating of the largest rivers on Earth "Niger" - this is the most valuable body of water in West Africa. The length is 4180 kilometers. In size, it is second only to the Nile and the Congo, whose basins are also located on the territory of this continent.

The source of the river is located on the slope of the Leono-Liberian Upland, to be precise, in the southeastern part of Guinea. It is worth adding that the Niger flows into the gulf of the Atlantic Ocean. Thus, the possession of the delta is formed. Speaking of the largest tributary, it is the Benue River.

9. The longest tributary river is the Irtysh. 4248 km

Located in the Xinjiang Uygur region of China. The length of this reservoir reaches 4248 kilometers. Therefore, it is larger than the Ob itself. In total, the Ob, together with the Irtysh River, create the longest watercourse in Russia. It ranks second in the overall length ranking in Asia.

The area of the basin is 1643 thousand square kilometers. Their origins of birches from the border of Mongolia, as well as China. It is worth noting that this river is rich in freshwater fish.

8. Lena. 4400 km

The length is 4400 kilometers. The area is 2490 thousand square kilometers. Thus, the Lena is the longest river in the territory Central Siberia. If you do not take into account 106 kilometers of the Bykovskaya channel, the length is 4294 kilometers. Large territory reservoir passes through the Irkutsk region. It is worth noting that Lena is considered the largest in Russia in terms of total area. At the same time, there are no analogues of Lena in terms of location in permafrost regions in the world. Winter fishing enthusiasts come here from all over the world.

7. Mekong. 4500 km

In wide circles, the reservoir is known as the "River of the Nine Dragons". It flows through the territory of the following states:

China;
Laos;
Thailand;
Cambodia;
Vietnam;
Myanmar.

On the Indochina peninsula, the Mekong is the most big river, the length of which is 4500 kilometers. The area of the basin is 810 thousand square kilometers. Speaking of water consumption, the figure is approximately 15,000 m³ / s. Thus, it is impossible to overestimate the importance of this fresh water reservoir!

6. The deepest river in the world is the Congo. 4700 km

Another large river located in Central Africa. The length of a large river is 4700 kilometers. It is worth noting that it is the deepest and ranks second in terms of length in Africa. In terms of water content, it is second only to the Amazon. In the upper reaches of the Congo, it exceeds the height of Kisangani.

This unique river, which crosses the equator twice. The slope is 0.36 m/km. The total area of the entire basin is 4,014,500 square kilometers. The source starts from the DRC, runs along the border with Zambia. There are other data, according to which it emerges from the Chambeshi River. Depth - 230 meters.

5. Parana. 4880 km

This is a long river located in South America. Its length is 4880 kilometers. Affects several states at once, including Argentina, Brazil and Paraguay. The area of the Parana River is 2,582,672 square kilometers. From interesting facts the following can be distinguished:

The Parana flows into the Gulf of La Plata;
shipping is well developed in the lower reaches of one of the longest rivers on the planet;
in the middle reaches of the Parana there is a border between Argentina and Paraguay;
the title translates big river from the language of the ancient Guarani Indians.

4. Huanghe. 5464 km

Finding a fresh water reservoir larger than the Yellow River is quite difficult. One of the largest rivers in China and Asia as a whole, translated means "yellow", which is associated with the presence a large number sediment. They give it a traditional and extraordinary yellowish tint. Not many people know that it was because of this river that flows into the yellow sea that the second body of water got its name.

The source of the Yellow River is located in the eastern part of Tibet, at an altitude of about 4 thousand meters. The total area is 745 thousand km².

3. Yangtze. 6300 km

The Yangtze translates as "long river". A really large river located in China is distinguished by its long length (6300 km), covering the territory of many countries of Eurasia. One of the largest rivers on the planet is considered the third on the Earth in terms of full flow. Its area is 1,808,500 square kilometers.

It is worth saying that the Yangtze covers many ecosystems, while it is home to unique endemic and rare, endangered species of marine animals. Particularly river dolphins.

2. Nile. 6853 km

The ex-leader in the top of the longest rivers today is the Nile, whose length is 6853 kilometers. The source of the fresh water reservoir originates in the East African Plateau. As a result, a huge delta with an area of 24 thousand square kilometers is formed. For the most part, the Nile flows in the desert.

The longest water system of the Nile, according to Brazilian researchers, is inferior to the Amazon, but most experts are convinced that it is the largest. However, the length of the Nile is inferior to the main competitor in this rating, so we placed the top in this way.

1. The largest river is the Amazon. 6992 km

The longest river in the world- The Amazon, the length of which is 6992 kilometers. The area is 7180 thousand square kilometers.

It should be recalled that in 2011 a world competition was held, in which the river received the status of one of the seven wonders of the world. For the most part, it flows in the Amazonian lowland, namely in the sublatitudinal zone. Forms a huge delta and flows into Atlantic Ocean. The area of the largest river island is 100 kilometers.

Earth is not called the blue planet for nothing. Most of the surface of our world is covered with water. It creates oceans, seas, lakes and, of course, rivers. There are a huge number of rivers on our planet: from very small to huge, which cross entire continents and carry their waters for thousands of kilometers. Rivers have great value for a person. Near the rivers are built big cities they give people drinking water and irrigate our fields, along the rivers a person transports a huge amount of goods.

Sometimes it is difficult to determine the length of a river because it is not always possible to tell where one river ends and the next one begins. We have put together a list for you longest rivers in the world.

5464 km

The Yellow River or Yellow River is the second largest river in China. The length of the river is 5464 kilometers. The river got its name from yellow color, which is given to it by the loess plateaus of Shanxi. The Yellow River begins on the mountain plateaus in Tibet, crosses all of Chinese territory and flows into the Yellow Sea. This river is considered the cradle of Chinese civilization. The Yellow River very often changes its course. The area of the river basin is 750 thousand square kilometers. The river provides irrigation and drinking water to 140 million people. A large number of large cities were built on this river.

5539 km

Yenisei is one of longest rivers Siberia. It starts on the border of Mongolia and the eastern part of Russia. It flows through the whole of Siberia and flows into the Kara Sea. Its total length is 5,539 kilometers and its drainage basin is over 2.8 million square kilometers. Numerous hydroelectric power plants have been built on this river, which supply electricity industrial enterprises Siberia. The construction of these huge structures had a negative impact on the ecology of the region. In addition, the Yenisei is the most important waterway in Western Siberia.

Mississippi 6275 km

The Mississippi is the largest river in North America. Its length is 3902 miles or 6275 kilometers. It begins in northern Minnesota and flows into the Gulf of Mexico. Lake Itasca is considered the source of the river. Another major river in North America, the Missouri, flows into the Mississippi. Mississippi fed by rivers 31 american state and two provinces of Canada. The total drainage area of the Mississippi is 3.27 million square kilometers. The name of this river is translated from the language of local Indians as "big (great) river." It has great importance for the US economy. There is an active navigation on the river, a huge variety of goods and passengers are transported along it.

6300 km

The Yangtze (6300 kilometers) is the largest river in China, which originates among the Himalayan glaciers and flows into the South China Sea. The basin area of this river is 1.8 million square kilometers. The Yangtze divides China into northern and southern part. This river is of great importance for the Chinese economy. The largest Chinese hydroelectric power stations were built on it, and the largest cities of China are located on this river.

6400 km

The length of this river is 6400 kilometers. The Amazon is formed at the confluence of two rivers. The river's drainage basin is over 7 million square kilometers (almost the size of Australia). Mighty rivers flow into the Amazon. It flows through the territory of the South American continent and flows into the Atlantic Ocean. The basin of this river is even larger than that of the Nile. Amazon flows through the territory following countries: Peru, Bolivia, Brazil, Colombia, Ecuador, Venezuela and Guyana. Her waters roll among rainforest South America, which are home to a large number of wild animals. Rainforests The Amazons are of great importance for the biosphere of our planet.

Nile 6650 km

Nile is the longest river on our planet. Its length is 6650 kilometers. It is located in northeastern Africa and flows into the Mediterranean Sea. The river flows through Ethiopia, Eritrea, Sudan, Uganda, Kenya and Egypt. The Nile originates in the central part of the continent, among the African lakes, passes through the sands of the Sahara and forms a delta when it flows into the Mediterranean Sea. The area of its drainage basin is more than 3 million square kilometers. 300 million people live in the basin of this river and their life is connected with the Nile. Large hydroelectric power stations have been built on this river, large canals have been dug. Navigation on the Nile is of great importance to several countries. The Nile is the cradle of one of the most ancient human civilizations - the civilization of Ancient Egypt.

Measuring the length of rivers is not an easy task, which, however, has been greatly simplified since the advent of artificial satellites. But even with the help of images from space, it is not possible to determine the exact length of the river. Difficulties in determining the beginning of the river may be due to a large number tributaries. Of all the tributaries, the one that begins at the farthest point from the mouth is considered the beginning of the river, giving the river a total total length, and the name of this tributary is usually not the same as the name of the river. It can also be difficult to determine where the river ends, because the mouth of the river is often an estuary, gradually widening and opening into the ocean.

Estuary (from lat. aestuarium - flooded mouth of the river) - a single-arm, funnel-shaped mouth of the river, expanding towards the sea. One can think of an estuary as a place where the sea is wedged into the mainland/island due to the washing out of rocks.

Seasonal changes also contribute to the complexity of calculating the total length of river systems. This list shows the lengths of river systems, that is, rivers, taking into account their longest tributaries.

10. Congo - Lualaba - Luvua - Luapula - Chambeshi

Below the mouth of the right tributary of the Atbara, the Nile flows through the semi-desert, having no tributaries for the last 3120 km.

For a long time, the Nile water system was considered the longest on Earth. In 2013, it was established that the Amazon has the longest river system. Its length is 6992 kilometers, while the length of the Nile system is 6852 kilometers.

Feluca is a small deck vessel with peculiar slanting sails in the form of a trapezoid or a triangle trimmed from one corner.

1. Amazon

The Amazon is a river in South America, the largest in the world in terms of basin size, full flow and length of the river system. It is formed by the confluence of the Maranion and Ucayali rivers. The length from the main source of Maranyon is 6992 km, from the source of Apacheta discovered at the end of the 20th century - about 7000 km, from the source of Ucayali over 7000 km.

However, there are long rivers not only on the ground, but also under it. Hamza is an informal name for the underground current under the Amazon. The opening of the "river" was announced in 2011. The unofficial name is given in honor of the Indian scientist Valiya Hamza, who has been exploring the Amazon for more than 45 years. Hamza flows at a depth of about 4 km underground through porous soils parallel to the Amazon. The length of the "river" is about 6000 km. According to preliminary calculations, the width of Hamza is about 400 km. The flow rate of the Hamza is only a few meters per year - this is even slower than the glaciers move, so it can be called a river rather conditionally. Hamza flows into the Atlantic Ocean at great depths. The water of the Hamza River has high level salinity.
