Channel Migration
Zone Assessment

In their natural state, rivers can be relatively stable or rapidly move across a valley bottom.  Channel migration is a natural process that results in bank erosion. Human actions can increase or decrease rates of channel migration and thereby impact ecological habitat and developed areas. Bank erosion and channel migration are responsible for a significant portion of flood damages throughout the world. Understanding the processes and areas affected by channel migration are critical for land planning, assessing flood and erosion risks, habitat restoration and protecting natural resources.
