1. Nile River: 6,650 km

River Nile (Source: Britannica)

The Nile is the longest river in the world, measuring roughly 6,650 kilometres in length. It runs through a large portion of the African continent and flows through several countries, including Uganda, Ethiopia, Sudan, South Sudan, the Democratic Republic of the Congo, Kenya, Tanzania, Rwanda, Burundi, and Egypt. The Blue Nile and White Nile are the Nile’s major tributaries that feed into this river, which flows southward and eventually empties into the Mediterranean Sea. The Nile is a major source of water and transportation, supporting approximately 40% of the population of Kenya.

2. Amazon River: 6,400 km

The Amazon River ranks as the second-longest river globally, spanning approximately 6,400 kilometres. Not only is the Amazon the second-longest river, but it also holds the title of the largest river in terms of volume or discharge. The sheer magnitude of the Amazon is such that two of the subsequent largest rivers in terms of volume are tributaries of the Amazon itself. Flowing through three South American countries—Brazil, Peru, and Colombia—the Amazon eventually empties into the Atlantic Ocean.

3. Yangtze River: 6,300 km

The Yangtze River, also known as the Chang Jiang, is a mighty waterway that flows across the heart of China. Stretching an impressive 6,300 kilometres (3,915 miles), it is the longest river in Asia and the third-longest in the world. Flowing eastward through a significant portion of China, the Yangtze River ultimately empties into the East China Sea. Additionally, it also serves as an unofficial dividing line between North and South China and has historically played crucial roles in providing drinking water, facilitating transportation, and supporting irrigation practices. In the present day, the Yangtze River is home to the Three Gorges Dam, which stands as the world’s largest power station.

In the southern United States, the Mississippi-Missouri River System spans approximately 6,270 kilometres in length and comprises the Missouri and Mississippi Rivers, the two longest rivers in the country. These rivers are often perceived as a unified major river system due to their confluence, which has historically played a pivotal role as a vital transportation route, enabling trade and commerce. Additionally, the Mississippi River has been instrumental in supporting a rich variety of wildlife throughout its course.

5. Yenisei-Angara-Selenga River: 5,539 km

The Yenisei River spans 5,539 kilometres, ranking as the fifth-longest river globally. This extensive system comprises multiple rivers coursing through Russia and Mongolia before ultimately flowing into the Arctic Ocean. While not notably deep, the river feeds into Lake Baikal, renowned as the deepest and oldest lake worldwide. Regrettably, concerns persist regarding contamination in the river system, attributed to radioactive discharges from a clandestine bomb production facility.

6. Yellow River: 5,464 km

The Yellow River, also known as the Huang He or Huang River, is the world’s sixth-longest and China’s second-longest river, spanning approximately 5,464 kilometres. It runs through nine provinces in China, starting from Qinghai in the west and ending near Dongying at the Bohai Sea. Known for its frequent flooding that has changed its course over time, the river now has many important hydroelectric dams and power plants and is home to around 160 different fish species.

7. Ob-Irtysh: 5,410 Km

The Ob River is approximately 5,410 kilometres long, flowing through vast regions of Russia before reaching the Arctic Ocean. Novosibirsk, Russia’s third-largest city, is located on the river’s banks, where the famous trans-Siberian Railroad intersects the waterway. The river is an important source of drinking water and irrigation and also generates hydroelectricity through facilities like Novosibirskaya GES. With over 50 fish species in its waters, the Ob River is a significant fishing area, supporting both sustenance and economic activity.

The Rio de la Plata is the eighth-longest river in the world, spanning an impressive 4,880 kilometres across Argentina and Uruguay. It holds the title of the widest river globally, with its eastern end opening into a vast, bay-like area that encompasses the Parana and Rio Grande rivers, creating a vast network of freshwater and saltwater that converges at its eastern end, forming a bay-like estuary.

9. Congo River: 4,700 km

The Congo River, the ninth-longest river, is Africa’s second-longest and second-largest in terms of discharge volume. It flows for 4,700 kilometres through multiple countries, including the Democratic Republic of the Congo, the Central African Republic, and Angola, crossing the equator twice before emptying into the Atlantic Ocean. With a depth of up to 220 meters, it holds the record as the deepest known river, and its seasonal flow surpasses 50,000 cubic meters, making it the most powerful river in Africa. This immense power is utilized by around 40 hydropower plants in the Congo Basin, highlighting its potential as a significant source of renewable energy.

10. Amur River: 4,444 km

Lastly, the Amur River, which stretches an impressive 4,444 kilometres, is the tenth-longest globally. It serves as a natural boundary between the Russian Far East and northeastern China before emptying into the Sea of Okhotsk, the Pacific Ocean, and the Strait of Tartary.

Hence, as we face the challenges of population growth, urbanisation, and climate change, understanding and protecting these vital waterways is more important than ever. These rivers are not only sources of water and life but also play a crucial role in shaping the landscape and supporting diverse ecosystems.
