The River Nile is the longest in Africa and also the longest river in the world. It is 4258 miles long. It passes through 11 countries, flows northward through the tropical climate of eastern Africa, and empties into the Mediterranean Sea. The river Nile has two major tributaries, which include the Blue Nile and the White Nile.
The White Nile starts at Lake Victoria, which is considered the largest lake in Africa. The White Nile is the portion of the Nile between Khartoum, Sudan, and Malakai, South Sudan. The name of the river came as a result of the light grey color that comes from the light-colored clay sediments in the water.
The White Nile tributary has a total length of 1295 miles. During the low water season, the flow of the White Nile is uninterrupted and contributes about 80% of Nile volume. The Blue Nile is also known as Abbay, it is about 900 miles long, and it flows from Lake Tana, Ethiopia, to Khartoum, Sudan. The Blue Nile's principal tributaries are the Rahad and Dinder rivers.
