Abstract: Resistance to flow in alluvial channels depends on the geometry of the bed patterns that are formed by the flow, the properties of the sediment, and the transport rate of sediment. A theory is presented to predict the geometry of the bed patterns (ripples, dunes, antidunes, and bars) and to evaluate the influence of the transport rate of sediment on the flow resistance. The theory is found to be in good agreement with experimental results.
