WebDowncutting is erosion of the streambed (bottom), thus increasing the depth of the stream channel.u000bu000b Lateral erosion is erosion of the stream sides (banks), thus increasing the width of the stream channel.u000b u000b Headward erosion is erosion of the stream at its start or head, thus increasing the length of the stream channel. WebThe downcutting is so rapid, the river maintains a meandering pattern while deepening its valley. River valleys form a significant part of Earth's landscape, but they are not the only land form created by running water. All streams and rivers come to an end. Most ultimately flow into the ocean or another large body of water such as a lake.

Once a stream has begun to cut back, the erosion is sped up by the steep gradient the water is flowing down. As water erodes a path from its headwaters to its mouth at a standing body of water, it tries to cut an ever-shallower path.
