The carrying Capacity on the Non—equlibrium Transportation of Suspended Load |
| |
| Abstract: | Based on the basic conception of the carrying capacity of suspended load, the formulas of equilibrium and non-equilibrium transportion for nonuniform suspended sediment are derived. The charateristics of the formulas are as follows:
a. The mechanisms of equilibrium and non-equilibrium transportation of nonuniform sediment are further clarified;
b. The transporting law of suspended load is described under various bed material and incoming flow and sediment conditions;
c. The formulas are easy to be applied and used widely. |
