Abstract/Description or Keywords An on-going sediment research project has been underway in
the Tsitika River watershed on northeastern Vancouver Island,
British Columbia since the early 1990s. Part of the program
studied sediment production during storms in two sub-basins,
Catherine Creek and Russell Creek, which are two typical Coastal
British Columbia streams. However, the two creek basins differ
in terms of bedrock lithology, basin morphology, and harvesting
history. This report presents a comparative analysis of the
sediment-production characteristics of the two sub-basins from
November 1991 to December 1998. Results of this analysis
provide some insight into the roles of various factors, including
forestry-related activities, in controlling the production and
transport of suspended sediment. The results of the study provide
important insights into watershed management, how to
interpret Coastal Watershed Assessment Procedure (CWAP)
data, and forest management implications regarding construction
and use of forestry roads on highly erodible bedrock types.
With further development, this research could lead to a regional
approach to characterizing sediment yields from specific morphological/lithological
terrain types.
