Nile River
Egypt has only one river - the river Nile, the longest river in the world.
The Nile River, often cited as the longest river in the world, is navigable along much of its length, facilitating boat traffic. However, this navigation is significantly impeded by a series of cataracts, or rapids, particularly in the southern part of Egypt and northern Sudan.
