COMMON LIMITING FACTORS in WRIA 22-23 and their impact to physical processes and salmon


Physical Process Effects

Floodplain impacts typically are a result of floodplain filling, dike and levee construction, and streambank armoring.   Floodplain impacts such as dikes and levees reduces the amount of food water storage capacity, which concentrates the flow and its energy to a more confined area.  This concentration of flow and energy contributes to scour, channel incision, and streambank erosion.
