Researchers believe that the Nile originated 30 million years ago in the mid-Tertiary Period.
It is the longest river in the world. There are two great branches of the Nile: the White Nile, from equatorial East Africa, and the Blue Nile from Ethiopia. The White Nile is joined by the Blue Nile at Khartoum, Sudan, and flows north through Egypt into the Mediterranean Sea.
The Nile River basin is immense and occupies an area about one-tenth of the continent of Africa. It includes portions of Tanzania, Burundi, Rwanda, Zaire, Kenya, Uganda, Ethiopia, The Sudan, and Egypt. It is estimated to drain an area of 1,293,000 square miles (3,349,000 sq. km.)
The river's water and the fertile soil along its banks created the perfect setting for the evolution of the civilizations that existed in the ancient world. The ancient peoples that lived along the river's banks cultivated the art of agriculture and were among the first to utilize the plow.The Nile still supports much of the population of Africans living along its banks, as well as the Egyptians -- the latter living between otherwise inhospitable regions of the Sahara Desert. The river flooded every summer, depositing fertile soil on the fields. The flow of the river is disturbed at several points by cataracts, which are sections of faster-flowing water with many small islands, shallow water, and rocks, forming an obstacle to navigation by boats.The sudd in the Sudan also forms a formidable obstacle for navigation and flow of water, to the extent that Egypt had once attempted to dig a canal (the Jongeli Canal) to improve the flow of this stagnant mass of water (also known as Lake No)
