What are the ten rivers with the largest flow in the world?

There are many large rivers in the world, and they can be ranked in many ways according to their length, drainage area, and runoff. If we only rank them by their length, the Nile River is the world's longest river, the Amazon River is the world's second longest river, and my country's Yellow River is also a major river in the world. But if we rank them by drainage area, the Amazon River is the world's largest river, and the Nile River is the world's sixth largest river. So if we only rank them by their runoff, which are the top ten rivers in the world?

First, the Amazon River

Located in the north of South America, the Amazon River is 6,440 kilometers long and is an important international river in South America. It flows through Brazil, Peru, Colombia and other South American countries, with a drainage area of ​​6.91 million square kilometers. The Amazon River has about 15,000 tributaries, the largest of which is the Madeira River, which is 3,200 kilometers long. In addition, there are many tributaries as long as 1,600 kilometers.

The Amazon River Basin is located in the tropics and has a tropical rainforest climate with abundant rainfall. Therefore, many tributaries of the Amazon River have large water volumes. Many tributaries flow into the main stream of the Amazon River, resulting in a large amount of water in the Amazon River. The river is dozens of kilometers wide, and Brazilians proudly call it a river sea. According to statistics, the average annual runoff of the Amazon River is about 693 billion cubic meters.

Second, the Congo River

Located in the central and western part of Africa, it flows through Angola, Zambia, Congo and other countries, with a total length of 4,700 kilometers. The latitude of the Congo River is similar to that of the Amazon River, both of which flow through tropical rainforests. The basin has sufficient rainfall and an average annual runoff of 141.4 billion cubic meters.

Third, the Yangtze River

The total length is 6,397 kilometers. It originates from the southwest side of Geladandong Peak in the Tanggula Mountains on the Qinghai-Tibet Plateau in my country and flows into the sea from west to east. The Qinghai-Tibet Plateau is the source of many large rivers in Asia and is known as the Asian Water Tower. The Yangtze River system is very developed and has many tributaries. The drainage area of ​​the four tributaries, the Yalong River, the Min River, the Jialing River, and the Han River, has reached 100,000 square kilometers. The average annual runoff of the Yangtze River is about 928.2 billion cubic meters.

Fourth, Orinoco River

Located in northern South America, the Orinoco River originates from the Parima Mountains on the border between Venezuela and Brazil, with a total length of 2,740 kilometers. The Orinoco River mainly flows through the tropical rainforest area and the Llanos savannah area. The basin has sufficient rainfall, with tributaries such as the Bentoari River and the Guaviare River, and an average annual runoff of about 914 billion cubic meters.

5. Rio de la Plata-Parana

Located in South America, it originates from the Brazilian Plateau and flows through Brazil, Paraguay, Uruguay, Argentina and other countries. The basin belongs to the subtropical climate zone with sufficient precipitation and an average annual runoff of about 725 billion cubic meters.

6. Brahmaputra River

It is a major river in Asia, with a total length of 2,900 kilometers. It originates from the Qinghai-Tibet Plateau in my country. The upper reaches are called the Yarlung Zangbo River. After flowing into India, it is called the Brahmaputra River. The average annual runoff is about 618 billion cubic meters.

7. Yenisei River

Located in northern Asia, it originates in Mongolia and flows from south to north into the Kara Sea in the Arctic Ocean. It is 5,539 kilometers long. The Yenisei River has a vast basin, covering most of central Siberia. The water flow in the upper reaches is turbulent, and the lower reaches flow through the permafrost zone. The average annual runoff is about 610 billion cubic meters, making it the largest river in Russia.

8. Mississippi River

Located in North America, it is 6,020 kilometers long and is the fourth longest river in the world. The Mississippi River has a vast basin and numerous tributaries, bringing together many famous rivers in North America. The entire water system is distributed in a dendrite-like pattern, with an average annual runoff of about 590 billion cubic meters.

9. Lena River

Located in northern Asia, it originates in the western part of Lake Baikal in Siberia and flows from south to north into the Arctic Ocean. It is 4,400 kilometers long. The Lena River has many tributaries, including the Vitim River, the Bolshoi Botom River, the Olekma River, etc., with an average annual runoff of about 540 billion cubic meters.

10. Irrawaddy River

Located in southern Asia, it has two main sources. The eastern source originates from the southern part of the Boshula Mountains in Zayu County, my country, which is called the Dulong River in China, and the western source originates from northern Myanmar, which is called the Mailikai River. The Irrawaddy River is 2,288 kilometers long and has an average annual runoff of about 486 billion cubic meters.
