The Nile covers eleven countries in Africa namely; namely, Tanzania, Uganda, Rwanda, Burundi, the Democratic Republic of the Congo, Kenya, Ethiopia, Eritrea, South Sudan, Sudan and Egypt. Egypt and Sudan rely so much on the Nile as the primary source of water.
The White Nile and The Blue Nile are the main tributaries of the Nile River. The White Nile is longer and rises in the Great Lakes region of central Africa, with the most distant source still undetermined but located in either Rwanda or Burundi. It flows north through Tanzania, Lake Victoria, Uganda and South Sudan. The Blue Nile begins at Lake Tana in Ethiopia and flows into Sudan from the southeast. The two rivers meet at north of Khartoum, Sudanese capital. After the two main tributaries converge, they flow through Sudan and Egypt then ends in a large delta and flows into the Mediterranean Sea.
