rapids
River's churning section
Rapids are sections of a river where the water flows swiftly over rocks and other obstacles, creating turbulent, choppy surface conditions.
The term is almost always plural, treating the stretch of rough water as a collective feature rather than a single point.
Rapids are graded by difficulty for whitewater sports, from Class I (easy) to Class VI (extremely dangerous).
We portaged around the rapids rather than risk capsizing.
