Abstract

In the previous paper, the authors theoretically analysed (dynamic) equilibrium bed slope in rivers with sediment transport. In this paper, the authors theoretically analysed static equilibrium bed slope in rivers, as well as dynamic equilibrium bed slope in rivers with sediment transport.<br>Combining the equations of motion and continuity for non-uniform steady flow with the condition of critical tractive force, the outhors introduced the fundamental equation of static equilibrium bed slope in rivers, by solving this equation of motion for non-uniform steady flow. From this fundamental equation, the authors introduced the equations of static equilibrium bed slope in rivers with gradually varied width and same width.
