The
Atbarah River (;
transliterated: Nahr 'Atbarah) in northeast
Africa rises in northwest
Ethiopia, approximately 50 km north of
Lake Tana and 30 km west of
Gondar. It flows about 805 km (500 mi) to the
Nile in north-central
Sudan, joining it at the city of
Atbarah . Its
tributary, the
Tekezé River, is perhaps the true upper course of the Atbarah, as the Tekezé follows the longer course prior to the
confluence of the two rivers (at 14° 10' N, 36° E) in northeastern Sudan. The Atbarah is the last tributary of the Nile before it reaches the
Mediterranean.
