Roles of downcutting in developing a stream
Downcutting deepens a stream channel relative to its surroundings by
eroding the bedrock or sediments at the bottom of the channel. This
process creates valleys or canyons and increases the stream's capacity to
transport sediment downstream.
Roles of headward erosion during development of a stream
Headward erosion extends a stream's length at its source by groundwater
sapping, which weakens and undermines material upstream, and by surface
runoff, which erodes soil and rock at the channel's origin.
