Cataracts of the Nile
(重定向自First Cataract)


The cataracts of the Nile are shallow lengths (or white water rapids) of the Nile River, between Aswan and Khartoum, where the surface of the water is broken by many small boulders and stones jutting out of the river bed, as well as many rocky islets. In some places, these stretches are punctuated by whitewater and are perhaps well characterized as rapids, while at others the water flow is smoother, but still shallow.
