High-frequency variability of vertical distribution of suspended sediment concentration under irregular waves

Based on the data of a field experiment in a storm environment, we examined the specific features of the variability of the vertical profiles of the concentration of suspended sand sediments at a discreteness shorter than the wave period. Physical mechanisms that determine the processes of suspension and shape the types of vertical distributions of sediments are considered. A mathematical model for the prediction of vertical distributions of the suspended sediments governed by irregular wave forcing is developed. The model is verified from data of field and laboratory experiments.
