Stream Channel Morphology
Major Fluvial Disturbances in Logged Watersheds on the Queen Charlotte IslandsMicroform - 1987
Reconnaissance investigations of disturbed stream habitats early in the Fish/Forestry Interaction Program studies identified extensive, recently accumulated sediments in mid-reaches of some streams. From historical air photo and land use studies it was determined that the sediment wedges were initiated by streamside and in-stream logging practices before 1970. A long term sediment budget was estimated for each basin to determine the relative importance of adjacent stream bank erosion (on-site land use effect) and other sediment sources - including off-site land use effects - in contributing to the sediment wedges. The most significant sediment sources in each basin were assessed in the field: minor sources were estimated from regional results.
