Ubangi River

Ubangi River is one of the longest rivers in the Central African Republic. The Ubangi River, sometimes written Oubangui River, forms the boundary between the Democratic Republic of the Congo (Kinshasa) and the Republic of the Congo (Brazzaville). The Ubangi is produced by the confluence of the Bomu (Mbomou) and Uele (Welle) rivers in Yakoma, Democratic Republic of the Congo, on the border with the Central African Republic, and runs west for about 350 miles (560 km). It bends northeast of Bangui and runs southwest for a longer distance. The Ubangi is roughly 1,400 km long when combined with the Uele (2,250 km). It has a mean discharge of 151,147 cubic feet (4,280 cubic meters) per second in Bangui.

The Ubangi divides into arms separated by elongated islands in its upper reaches, while elsewhere confining rocks create rapids like those of Bangui. The Ubangi's vast course is broken by sandy shoals as it enters the Congo basin. Rapids still obstruct several of its tributaries. Flat, marshy lowlands and low divides slope east and southeast from the western highlands to the Congo River in the area between longitude 16° E and the Ubangi.
