BOMU RIVER

also called Mbomou, in the Central African Republic, headstream of the Ubangi River. The Bomu River rises 30 miles (50 km) northwest of Doruma, Congo (Kinshasa), and flows 450 miles (725 km) west, forming, together with the Ubangi, the frontier between Congo and the Central African Republic. Its course takes it in a wide curve through savannas, past Bangassou, to join the Uele River at Yakoma, where it forms the Ubangi River. Its lower course contains rapids. The Bomu was discovered from the north in 1877 by a Greek, P. Potagos. Wilhelm Junker, a German explorer from Moscow, navigated its upper course, and in 191011 a French expedition made a complete hydrographic survey of the river.
