Abstract
Willows are one of the most predominant species vegetated in many channelized rives. Willows tend to sprout and grow mostly along shoreline of the main channel. Since the riparian zone is exposed to river flow, willows vegetated there could be frequently destructed by flood flows depending on channel's geomorphology and flood frequency. If a river restoration would be properly carried out, overgrowth of riparian willows could be efficiently controlled and minimized by using natural flow forces. Therefore, it is a key issue to understand hydrodynamics of riparian willows for a labor-saving river management. In this study, a numerical analysis and laboratory experiment were performed in order to examine hydrodynamics of an open channel with compound cross section vegetated along shoreline.
