摘要：

The sediment transport problem in shallow flows, such as furrow flows, in the upper flow regime is formulated based upon continuum mechanics principles. A mathematical expression which is a modification of the classical stability criterion of flow over a fixed bed is obtained for the case when a movable sediment layer is present near the bed of the channel. Coincident with this stability criterion, the amount of sediment being moved is defined as the transport capacity of the flow. The results suggest the dependence of the capacity on the sediment properties, active layer thickness, channel gradient and the hydraulic properties, of the flow. Comparison of the theoretical results with experimental data revealed a general agreement.
