摘      要：Large woody debris and woody vegetation can exert a major influence on channel hydraulics and morphology, particularly in smaller (30 m wide) streams. Although debris and vegetation have long been used for channel erosion and sedimentation control, scientifically-based guidelines for designers are scarce. Recent advances in understanding vegetative effects on flow and sediment transport are reviewed. The effects of vegetation on the flow field leads to enhanced deposition within and adjacent to vegetated zones, and possibly erosion *** factors must be carefully evaluated when designing vegetative treatments.
