| Abstract: | In order to study the interactions between flow movement,sediment transport and river bed deformation and to enhance the basic theory for the one-dimensional flow and sediment mathematical model,the characteristics of the one-dimensional mathematical models for non-equilibrium transport of suspended load was analyzed based on the characteristic theory of hyperbolic system and singular perturbation theory.The results show that most of conventional models were decoupled in the characteristics and can not well... |
