| Abstract: | The sediment load, particle size distribution, and ratio between suspended and bed load components. are analyzed for some large rivers in Russia and China. The relationship is shown between the longitudinal changes in sediment load and the directions of vertical river channel deformation, i.e. river incision or sedimentation, which in turn are supported by results of analysis of long-term stage discharge curves. It seems that branching channels are common for the rivers, except where the sediment load is great (such as in the Yellow River). Conditions for forming different types of river channels are defined with the help of diagrams showing the water discharge-slope and slopesediment concentration relationships. |
