Description: "Abstract - The effects of multiple logging disturbances on peak flows and suspended sediment loads from second-growth redwood watersheds were approximately additive. Downstream increases were no greater than would be expected from the proportion of the area disturbed. Annual sediment load increases of from 123 to 269% were measured in tributary watersheds but were not detected at the main channel gages, implying that sediment was being temporarily stored in the intervening channels. The failure of previous studies to detect increases in large peak flows following timber harvests may be due to variability in measurements rather than absence of an effect. A few sites are responsible for a large proportion of the erosion resulting from management-related disturbances."
