Description :
The objectives of this study were 1)to systematically vegetate a straight, degraded experimental channel with freely adjustable banks and beds and to document the effects of vegetation density on alluvial response and channel morphology and 2) to compare these experimental results with a recently developed numerical model capable of simulating flow, sediment transport and bed morphology in meandering streams with riparian and in-stream vegetation. This was accomplished by constructing a distorted Froude-scale physical model for a designated prototype, Abiaca Creek in northern Mississippi, USA. It is envisioned that such numerical models could become the primary tool for designing future stream restoration programs involving vegetation and assessing the long-term stability of such activities.
