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.
