The Atbarah River is a significant tributary of the Nile River in northeastern Africa. It flows through Sudan and is approximately 800 kilometers long. The river originates in the Ethiopian highlands and travels northward, eventually joining the Nile near the city of Khartoum. The Atbarah River is known for its seasonal flooding, which can impact local agriculture and communities. It is also an important water source for irrigation in the surrounding regions. The river's basin supports various ecosystems and wildlife, contributing to the biodiversity of the area.
