Abstract

This study invesigates the effect of coarse woody debris, CWD, on bankfull channel dimensions and in-channel sediment storage along second-order streams. Comparisons are made between streams that have experienced recent debris slides and those that have not. CWD channel obstructions are larger but less frequent along debris-slide-affected streams. Dendrochronological evidence indicates that CWD can remain in channels for over 100 yr. CWD causes channel widening along all study streams, but the volume of sediment stored in the channel behind CWD obstructions is up to 4 times greater than the volume of sediment represented by bank erosion associated with CWD
