Application of Dispersion Equations of Supended Load Movement |
| |
| Abstract: | Based on the profile two dimensional dispersion equation of suspended load movement,vertical distribution formulas of saturation sediment content,one dimensional mass conservation equations of suspended load movement and profile two-dimensional practical equations are deduced by proper assumption.Then,“α coefficient”is redefined and theoretical calculation formulas are given.Finally,the uniqueness of carrying capacity is described. |
