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.
