Region 10 Channel Type Revision

The Alaska Region Channel Type Revision is an update to the original Channel Type User Guide published in 1992.  The Channel Type Classification System divides the stream network into nine basic fluvial process groups.  These process groups describe the interrelationship between watershed runoff, landform relief, geology, and glacial or tidal influences on fluvial erosion and deposition processes. Individual channel type classification units within each process group are defined by physical attributes such as channel gradient, channel pattern, stream bank incision and containment, and riparian plant community composition.
