Ubangi River

Ubangi River
River, central Africa.

Formed by the Bomu River and the Uele River on the northern border of the Democratic Republic of the Congo, it flows west and south, forming part of the boundary with the Central African Republic and with the Republic of the Congo. It then empties into the Congo River. It is 700 mi (1,126 km) long; with its longest headstream, it is double that length.

also spelled  Oubangui,  

      largest right-bank tributary of the Congo River, marking the border between Congo (Kinshasa) and Congo (Brazzaville). The Ubangi is formed by the union (near Yakoma, Congo [Kinshasa], on the border of the Central African Republic) of the Bomu (Bomu River) and Uele (Welle) rivers, and it then flows west for about 350 miles (560 km). It bends northeast of Bangui and flows a somewhat longer distance southwest. The total length of the Ubangi, with the Uele, is approximately 1,400 miles (2,250 km). Its mean discharge at Bangui is estimated at 151,147 cubic feet (4,280 cubic m) per second; from May to December, when in flood, the discharge may exceed 494,000 cubic feet (14,000 cubic m), while during low water (February–April) it drops to 35,300 cubic feet (1,000 cubic m).

      In its upper reaches the Ubangi divides into arms separated by elongated islands, while elsewhere confining rocks cause rapids, such as those of Bangui. The Ubangi changes on entering the Congo basin, its wide course being split by sandy shoals. Some of its tributaries are still impeded by rapids. The area between longitude 16° E and the Ubangi consists of flat, swampy valleys and low divides descending east and southeast from the western hills to the Congo River. Much of the region is covered with dense equatorial rainforest, and large portions of the region that lie northeast and southwest of the Sangha River are permanently inundated. The Ubangi River joins the Congo at the village of Irebu, at the mouth of the Irebu Channel. Low-lying, swampy Lake Tumba drains through this channel into the Congo River. The Congo waters during late April to late June push back those of the Ubangi. Some clearance for navigation has taken place, and barges of 600 tons can reach Bangui.

      The Uele was visited from the north in 1870 by the German botanist Georg Schweinfurth, and the Russian explorer Wilhelm Junker in 1882–83 established it as part of the Congo River system.
