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. |
