The Nile River is the primary river that flows through Egypt. It is one of the longest rivers in the world, stretching approximately 4,135 miles (6,650 kilometers) and serving as a critical water source for millions of people. The Nile has historically been essential for agriculture, facilitating the growth of crops in a predominantly arid region. Its annual floods deposited nutrient-rich silt along its banks, which supported the ancient Egyptian civilization. The river flows northward through various landscapes, eventually emptying into the Mediterranean Sea. The Nile remains a vital lifeline for Egypt, sustaining ecosystems and contributing to the economy through fishing and tourism.
