is nile a perennial river
The Nile River is 6,700km long, and hence is the longest river in the world. Despite the fact that the Nile flows through one of the harshest deserts, and travels the last 2,400km without a single tributary, it never runs dry. The Nile river is said to be the life of the Egyptians.he Blue Nile River. The Blue Nile got the 'blue' part of its name because of its muddy color due to the huge amount of fertile soil it erodes from the Ethiopian highlands. Why they called it blue rather than the more logical color of brown, dark brown or even black is open to conjecture.
