Rapids and numerous whitewater are characteristics of downcutting and a youthful stage of valley evolution. Other characteristics include rough or irregular channels and V-shaped valleys.
A narrow v-shaped valley
mass wasting on the valley sides
The broad flat valley floors that are carved out by wondering streams are called flood plain and the two methods of the streams eroding the rocks to form the flood plain are down cutting and lateral erosion.
A Floodplain.

The downcutting action of a stream that has a profile suggesting the form of the letter "V".
mass wasting on the valley sides
Mass wasting is the downslope movement of soil and weathered rock debris. Streams can deepen valleys by downcutting (erosion), but widening or enlarging of the valley via erosion of the sides or slopes is accomplished largely through mass wasting. Mass wasting delivers the weathered rock material and soil to the streams, which carry it away to some site of deposition.
Streams that are first forming.
Valley is a noun. But it is used as an 'adjunct' or adjective to describe things in or about a valley: valley floor, valley streams, valley residents.
