12 Longest Rivers in African Continent

Interestingly, Africa remains one of the continents globally with the most extensive and longest rivers, surrounded by other famous and notable rivers that make up the planet earth. 

The river generally means a vast body of water, which flows in a channel to the sea or another river, usually unidirectional. 

Although rivers surround the African continent, there is still segregation; this segmentation ranges from shorter to longer, deep to shallow ones.

Keep reading to get the full details of the twelve (12) longest rivers on the African continent, arranged in descending order.

1. Nile River

The Nile River, which makes up two Rivers, namely the White Nile and the Blue Nile, is the longest in Africa and the second-longest worldwide, flowing from Burundi Lake Victoria into the Mediterranean Sea frontier of Egypt. 

Also, the White Nile, a component of the River Nile, is long too and flows in the Great Lake region.

The River Nile passes through 10 African countries such as Burundi, Uganda, Egypt, Ethiopia, Kenya, Rwanda, South Sudan, Sudan, Tanzania, and the Democratic Republic of Congo.

Origin of Nile River

The White Nile originates or starts from Burundi and made its way via the Kagera River in the southern part of Africa and finally empties into the Mediterranean Sea in Alexandria, Egypt.

The Nile, which got its name from the Greek word ” Neilos,” meaning valley, although named in Latin as ” Nilus,”. This great river was associated with Egypt mainly with the famous ancient Egyptian irrigation practice and Joseph’s famous biblical story.

The Blue Nile originates from Ethiopian in Lake Tara around the Abyssinia mountain. The Blue Nile from Ethiopia meets the White Nile at Khartoum, in present-day North Sudan.

In modern time history, John Hanning Speke is the one who discovered the Nile River around 1858.

  • Length of the Nile River

The Nile River has a length of 6,693 km, containing about 80% of water, tributaries, and other components.

  • Basin Size of Nile River

Like every other river, the Nile River has a basin size measuring 1,300,000 sq mi [3,400,000 sq km].

The primary sources of the River are the White River and the Blue River.

  • Discharge rate

On average, this great river discharges at about 2,830 m³/s (99,956 ft³ per second).

2. Congo River

Congo River, previously Zaire River in west-central Africa, is the 2nd largest river in Africa after the Nil river and the deepest recorded river worldwide.

Two rivers that form river Cong are Chambeshi and the Lualaba river, hence the emergence of the Congo-Lualaba-Chambeshi River system.

Again, river Congo basins spread over 3,349,000 square kilometres.

  • The discharge rate 

In the rainy season, especially at the peak, more than 1,800,000 cu ft (50,000 cubic meters) of water flows from this river into the Atlantic Ocean per second.

The sources of the Congo

The primary sources of this river are the mountains of the East African Rift, Lake Tanganyika, highlands, and Lake Mweru.

Hydroelectric power opportunities

The high flow of the congo river per second during the rainy season provides enormous opportunities for the river, alongside the tributaries, to generate hydropower.
