抄録

In this paper, the authors theoretically analyzed the equilibrium bed slope in rivers with sediment transport with gradually varied width and same width of rectangular cross sections, in consideration of the new developments in the many researches of flowing water and sediment transport in open channels. Combining the equations of motion and continuity for non-uniform steady flow with the equations of motion (formula for sediment transportation) and continuity for sediment transport and the equations of the resistance law for flowing water with sediment transport, the authors introduced the fundamental equation of the equilibrium bed slope in rivers with sediment transport by solving the equation of motion for non-uniform steady flow. Furthermore, the authors introduced the formulas of the equilibrium bed slope in rivers with sediment transport with gradually varied width and same width of rectangular cross sections from above fundamental equation.<br>Last of all, a numerical example was added to demonstrate the method of application to a river with sediment transport.
