The Nile is a major north-flowing river in North Eastern Africa. It is about 6,650 km (4,130 mi) long, and it is also an “international” river as its drainage basin covers eleven countries, namely, Tanzania, Uganda, Rwanda, Burundi, the Democratic Republic of the Congo, Kenya, Ethiopia, Eritrea, South Sudan, Republic of the Sudan and Egypt. The Nile is the primary water source of Egypt and Sudan.
It is the longest river in the world. It rises South of the Equator and flows Northward through north Eastern Africa to drain into the Mediterranean Sea.
The river Nile has two major tributaries, the White Nile and Blue Nile. The White Nile is considered to be the headwaters and primary stream of the Nile itself. The Blue Nile, however, is the source of most of the water and silt. 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.
