Rapid
A rapid is a section of a
river where it loses elevation over a relatively short distance , causing an increase in water flow and
turbulence. A rapid is a
hydrological feature between a
run and a
cascade. A rapid is recognized by the river becoming shallower and having rocks exposed above the flow surface. As flowing water splashes over and around the rocks, air bubbles become mixed in with it and the water takes on a white colour, forming what is called "
whitewater". Rapids occur where the bed material is highly resistant to the erosive power of the stream in comparison with the bed downstream of the rapids.
