The Byoma falls (formerly known as the Stanley Falls) is found on the River Zaire in Africa. Its volume of waterfall is measured by the amount of water flowing down it in unit time. 17,000 cubic meters of water gushes down the Boyoma Falls every second, while in the same time only 6,000 cubic water flows over the Niagara Falls (this is regarded as the world’s most famous waterfall). Therefore, there is not much difference in their widths. These falls also consists of seven cataracts with each no more than 5 m (16 ft) high. They extend over over more than 100 km (62 mi) along the curve of the Lualaba River. This River is between the river port towns of Ubundu and Kisangani. At the bottom of the rapids, the Lualaba river becomes the River congo. The cataracts (all Seven) have a total drop of 61 m (200 ft). With the two major ones being Ubundu- this forms a narrow and crooked stream that is hardly accessible, and the other that can easily be seen and also be visited from Kisangani. Boyoma Falls is the largest waterfall by volume of annual flow rate in the world, making it nearly ten times larger than the next largest waterfall in the world by volume annual flow rate.
