Description:

Channel migration is the natural process by which streams move laterally over time. It is typically a gradual phenomenon that works over many years to effect significant migration. In some cases, usually associated with flood events, significant migration can happen rapidly. Channel migration can and has created hazardous conditions within Oregon’s developed riparian areas. Areas of high susceptibility to rapid and potentially catastrophic migration are known anecdotally, but statewide susceptibility screening has not been performed. This dataset represents a screening of channel migration susceptibility for the primary and (if applicable) secondary drainage in each subbasin (HUC-8) that intersects with the State of Oregon.



Copyright Text: The screening and data development were performed by the Oregon Department of Geology and Mineral Industries. It was funded by the Oregon Department of Land Conservation and Development, Planning Services Division.
