Non-equilibrium Sediment Transport: Numerical Experiments

In this paper, the non-equilibrium suspended sediment of non-uniform particle size is reviewed. Some simple numerical experiments were carried out to study the dimensionless coefficient, which characterizes the rate of attaining carrying capacity in non-equilibrium suspended sediment transport in reservoirs. From the sensitivity analysts, α is a function of particle diameter, and the value of α is very sensitive to the spatial variation for larger particles, but has less effect for finer particles. For reservoir sedimentation, in which the suspended sediment mainly consists of silt and clay (d<0.02mm), an empirical constant α =0.25 appears to be valid.
