Description This document explains channel migration processes and stream channel patterns in Western Washington, providing a succinct and readable summary of scientific concepts relevant to floodplain management and restoration. As well posing a hazard to adjacent communities, channel migration is the primary physical process creating biodiversity on floodplains. Channel Migration Zones (CMZs) can therefore provide a vital tool for achieving multiple benefits in floodplain management decisions. As well as providing fundamental concepts for floodplain management and restoration, this document supports mapping of CMZs required for communities updating their Shoreline Master Programs.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
