Non-Equilibrium Transport of Non-Uniform Suspended Sediment |
| |
| Abstract: | Based on the basic concept of sediment carrying capacity and the three methods of suspended sediment exchange with bed meterial, the formula of sediment carrying capacity have been obtained under Non-equilibrium and equilibrium conditions in this paper. The mechanism of Non-equilibrium transport sediment is represented also. The formulas can be widely used in one or two dimensional mathematical models. |
