Oubangui River

The Ubangi River (/juːˈbæŋɡi/ or /uːˈbæŋɡi/), also spelled Oubangui, is the largest right-bank tributary of the Congo River in the region of Central Africa. It begins at the confluence of the Mbomou and Uele Rivers and flows west, forming the border between Central African Republic (CAF) and Democratic Republic of the Congo. Subsequently, the Ubangi bends to the southwest and passes through Bangui, the capital of CAF, after which it flows south – forming the border between Democratic Republic of the Congo and Republic of Congo. The Ubangi finally joins the Congo River at Liranga.

The Ubangi's length is about 1,060 kilometres (660 mi). Its total length with the Uele, its longest tributary, is 2,270 kilometres (1,410 mi). The Ubangi's drainage basin is about 772,800 square kilometres (298,400 sq mi). Its discharge at Bangui ranges from about 800 cubic metres per second (28,000 cu ft/s) to 11,000 cubic metres per second (390,000 cu ft/s), with an average flow of about 4,000 cubic metres per second (140,000 cu ft/s).

Together with the Congo River, it provides an important transport artery for river boats between Bangui and Brazzaville.
