Abstract: Presented herein are the results of a study carried out to determine the influences of ice cover presence on transverse bed slope, flow and sediment transport in a curved alluvial channel. The study entailed formulation of flow in a curved channel as a damped, forced oscillatory system, for which changing channel alignment prescribes a forcing function and transverse bed slope is a dependent variable of fluctuating magnitude. The study also entailed conduct of a laboratory experiment using a curved channel. It was found, both from formulation and experiment, that cover presence can appreciably reduce transverse bed slopes.
