Over four thousand miles in length, the Nile River is thought to be the the longest River in the world. Its depth varies between 26 feet to 36 feet; deep enough for most vessels but not deep enough for the large commercial tankers necessary for economically feasible transport for oil, petroleum, and grain. It varies in width from a slender thousand feet to 4.6 mile wide.
Several African countries border on both sides of the Nile. As a result, these countries south of Egypt benefit from the transport of foodstuffs and minor industrial products in amounts these poorer countries can pay. Most are tribal in governance which makes trade and commerce difficult.
