UBANGI , a See also:

river of See also:Equatorial See also:Africa, the See also:chief See also:northern affluent of the See also:Congo (q.v.). The Ubangi (otherwise Mubangi or Mobangi) enters the Congo by various mouths between o° 22' and o° 37' S. and 17° 40' and 17° 50' E. The See also:main channel,fully 1 m. wide, joins the Congo in o° 31' S. The Ubangi is formed by the junction of the Mbomu and the Welle, both of which rise on the See also:north-eastern rim of the Congo See also:basin. The See also:water-parting between the See also:Bahr-el-Ghazal affluents (See also:Nile See also:system) and the Mbomu headstreams is not very clearly marked, but high hills See also:running parallel with the Nile between See also:Albert See also:Nyanza and Dufile sharply See also:separate the valley of the Welle and other See also:west-flowing streams from that of the See also:Mountain Nile. The chief of the headstreams of the Welle (known in its upper course as the Kibali) rises on the western slope of a See also:hill about 40 M. west of See also:Wadelai. It is joined by several small streams, the main river flowing in a W.N.W. direction. After a course of over 700 m. (during which it receives one large See also:southern tributary—the Bomokandi—and other considerable affluents) the Welle joins the Mbomu in 4° to' N. 22° 37' E. The Mbo,nu, which has two large northern tributaries, the Shinko and the See also:Bale, rises in 4° 50' N. 27° 12' E.

For some distance it runs parallel to and about too m. north of the See also:

lower course of the Welle. About 23° 12' E. it turns sharply See also:south until its junction with the Welle. In its lower course the Mbomu is interrupted by many falls and rapids. A See also:short distance below the junction of the Mbomu and Welle the Kotto, coming from beyond 8° N., on the See also:borders of See also:Darfur, and forming the most northerly See also:extension of the Congo basin, enters the See also:united stream, now known as the Ubangi, on the right See also:bank. The remaining tributaries, mostly on the right bank, are smaller, but the Kemo, which joins the Ubangi near its most northern point (5° 8' N.), is of some importance as offering water communication to within a short distance of the See also:Shari basin. Below the Kemo confluence the Ubangi, which has hitherto continued to flow W.N.W., makes a See also:great See also:bend south and runs into the Congo after a southerly course of 400 M. Shortly after receiving the Kemo the river forces its way through a See also:line of hills whose tops rise 600 to 800 ft. above the See also:banks of the stream. Here are the Zongo or Grenfell rapids, which are a barrier to See also:navigation See also:save for small boats at See also:flood See also:season. Above the Zongo rapids the river is navigable up to the confluence of the Welle and Mbomu, and the Welle is navigable at high flood up to the Bomokandi confluence in 26° 8', though the stream is much interrupted by rapids. From the Mbomu-Welle confluence to the junction of the Ubangi with the Congo the river has a course of fully 700 m., while the Ubangi-Welle combined exceeds 1400 M. From its mouth to Zongo rapids, a distance of 35o m., the stream is navigable by steamers See also:drawing 3 ft. of water. In See also:general the Ubangi flows through a fertile and forested region.

The Welle was discovered from the north by G. A. See also:

Schweinfurth in 187o; i.e. seven years before the See also:discovery of the course of the Congo by H. M. See also:Stanley. By Schweinfurth the Welle was believed to belong to the See also:Chad system, but W. See also:Junker, who (1882–1883) followed the river to near its confluence with the Mbomu, made it clear that the Welle belonged to the Congo system. In 1885 the Rev. See also:George Grenfell, of the Baptist Missionary Society (who had discovered the mouth of the river in 1884), ascended the Ubangi as far as the Zongo rapids. He was followed in 1886–1889 by the Belgian A. See also:van Gele, who in the last-named See also:year finally established the identity of the Ubangi with Schweinfurth's Welle. The Mbomu was discovered from the north in 1877 by a See also:Greek, Dr P. Potagos, and its upper course was followed for some distance by Junker.

The Ubangi and the Mbomu See also:

form the frontier between Belgian Congo and See also:French Congo, the northern banks of both streams belonging to See also:France.
