A New Method to Calculate Mixed-Layer Thickness Based on Sand Wave Movement

Abstract:

It is pointed out that the influence of the time step in the unsteady non-uniform sediment mathematical model must be considered when to calculate the mixed-layer thickness in this article. And then a new method to calculate the mixed-layer thickness is obtained based on the sand wave movement. This method can well reflect the effect of the time step on the mixed-layer thickness, and has a wide field of application in the numerical simulation of natural river sediment transport.
