The Nile Delta is a delta formed in northern Egypt (lower Egypt), where the Nile branches into two branches that flow into the Mediterranean Sea. The Damietta branch is in the east and ends in Damietta, and the Rosetta branch is in the west and ends at the city of Rosetta. It is one of the largest deltas in the world - it extends from Port Said in the east to Alexandria in the west. It was called the Delta because it resembles a triangle. It occupies an area of 240 km on the Mediterranean coast. The delta is characterized by fertile agricultural lands suitable for cultivation at any time.
