- The White Nile originates in the Great Lakes region of Africa.
- Its major sources include:
• Lake Victoria, which is the largest lake in Africa and is located on the border of Kenya, Tanzania, and Uganda.
• Lake Albert, which is located on the border of Uganda and the Democratic Republic of the Congo (DRC).
- From Lake Albert, the White Nile flows north through Sudan, where it is joined by the Bahr el Ghazal and Sobat Rivers.
- The Bahr el Ghazal River is the main tributary of the White Nile and originates in the marshes of Southern Sudan.
- The Sobat River originates in the Ethiopian Highlands and joins the White Nile near the town of Malakal.
Blue Nile:
- The Blue Nile originates in the Ethiopian Highlands, specifically in Lake Tana.
- Lake Tana is located in the northern part of Ethiopia and is the source of the Abay River, which is known as the Blue Nile after it crosses the border into Sudan.
- The Blue Nile flows westward through Ethiopia and Sudan, where it converges with the White Nile near Khartoum, Sudan.
- The Blue Nile contributes significant amounts of water to the Nile River during the rainy season, which typically occurs between June and September each year.
