Sedimentation and erosion lead to what characteristic of streams?

Sedimentation and erosion of a stream can create channelization.  It can create numerous small channels to flow. The erosion can create the banks of the stream to disappear quickly while the sedimentation will reduce the depth of the stream, resulting in overflow along the banks. This can create great amount of destruction. The new channels can flood new areas and destroy both crops and livelihood. The sedimentation can also give birth to new land due to constant deposition of silt.
