Atbarah River
The Black Nile, also known as the Atbarah River, is a river in northeast Africa. It rises in northwest Ethiopia, about 50 kilometers north of Lake Tana and 30 kilometers west of Gondar. It then flows for about 805 kilometers (500 miles) to the Nile in north-central Sudan, where it joins it at Atbarah (17.677°N 33.970°E). The Tekezé (Setit) River, a tributary of the Atbarah, may be the true upper course of the river, as it 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 Nile's final tributary before it enters the Mediterranean.
For the majority of the year, it is nothing more than a stream. During the rainy season (generally from June to October), the Atbarah rises 18 feet (5 meters) above its normal level. At the moment, it forms a formidable barrier between the northern and central districts of Ethiopia's Amhara Region. Aside from the Tekezé, other significant tributaries of the Atbarah include the Shinfa River, which rises west of Lake Tana, and the Greater Angereb, which rises north of Gondar.
