| 摘 要： | I. ON THE INFLUENCING FACTORS OF THE SEDIMENT~LADEN FLOW VELOCITY PROFILEThe influence of sediment on the water--now structures must be considered when thevelocity profile of the sediment--laden now (or turbid flow) is studied. widely usedparameters for reflecting thoses influences are the sediment concentrahon and theffichardson number, where Ri represents the variation of the concentration gradient.Generally, the vertical distributions of sediment concentration and th…

| Abstract: | The velocity profile of sediment-laden flow can be related to the concentration distribution and concentration gradient. A relationship between the velocity profile and concentration distribution is developed covering clear water and sediment-laden flow (including homogeneous and heterogeneous flow). The relationship suggested here has been verified with experimental data. Also a two-layer model is developed. |
