—To regulate human-induced changes to fish habitat, resource managers commonly set standards based on maximum allowable changes. For example, new legislation in British Columbia (BC), Canada, calls for restrictions on harvesting of trees and related activities near temperature-sensitive streams. However, methods for designating such streams are still(More)
The objective of this chapter is to describe some key linkages between the ecology of salmonid fish and the hydrologic and geomorphic features of their spawning streams in British Columbia. Salmonid refers to all species in the Salmonidae family of fishes, which includes Pacific salmon and trout (Oncorhynchus spp.), char (Salvelinus spp.), grayling(More)
9 [1] Analyses of bed load transport data from four streams 10 in British Columbia show that the activity of mass spawning 11 salmon moved an average of almost half of the annual bed 12 load yield. Spawning-generated changes in bed surface 13 topography persisted from August through May due to lack 14 of floods during the winter season, defining the bed(More)
This study develops a quantitative framework for estimating the effects of extreme suspended-sediment events (SSC>25 mg L(-1)) on virtual populations of Chinook (Oncorhynchus tshawytscha) and coho (O. kisutch) salmon in a coastal watershed of British Columbia, Canada. We used a life history model coupled with a dose-response model to evaluate the(More)
