Rapids are sections of a river where the gradient of the river bed is relatively steep resulting in an increase in the riverâs turbulence and velocity. They form where the gradient of the river is steep and the bed is composed mainly of hard rocks.n the upper course of a river, its load is large and mainly transported by traction along the river bed. When flowing water encounters bedload, it is forced over it and downcuts behind the bedload in swirling eddie currents. These currents erode the riverâs bed and create small depressions in it.
