Nile

The Nile is the world's longest river, flowing approximately 6,650 kilometers (4,130 miles) through northeastern Africa. It is a vital water source for countries like Uganda, Ethiopia, Sudan, and Egypt, supporting agriculture, drinking water, and transportation. The river has two main tributaries, the White Nile and Blue Nile, which converge in Sudan. Historically, the Nile's annual flooding deposited nutrient-rich silt onto its banks, enabling ancient Egyptian civilization to flourish. Today, dams and water management projects aim to control its flow and harness its resources, though they also raise environmental and political concerns across the region.
