Study of scouring-deposition control simulation of the Yellow River estuary

A dynamical model of the sediment transport river network is proposed by considering the characteristics of sediment scouring of deposition.In order to search a method to reduce the deposition in downstream reaches,we attempt to adjust the proportion of the transported sediment in our model.When it is in a lower-water season,all the river basin is at a relative steadier state,we attempt to adjust the flow of a certain tributary to reduce the deposition of the low reach.As it changes from the lower-water season to the higher-water one,the master stream section is at transient state,the state in the low reach can be transformed from depositing to scouring one via injecting rinsing(or seawater) into the segment bellow which the reach is in deposition state.
