A REVIEW OF THE WAVE-INDUCED SEDIMENT RESUSPENSION

The re-suspension of bottom sediment, which plays significant roles in the evolution of marine sedimentary landscape, coastal environmental dynamics, and exchange of materials and energies, is an important part of the modern sediment dynamic process. In this paper, we systematically analyzed and discussed the features of wave-induced sediment re-suspension and the dynamical mechanisms, incident conditions, characteristics of wave-suspended sediments, and the post-rework of the seabed sediment by wave-induced sediment re-suspension, and further put forward the unsolved problems, based on the conducted work and related achievements. This work is of great value for further understanding of the sediment re-suspension, transportation, and the long-distance movement of sediment discharge in the sea, and instructive to the marine geologic hazard mitigation, such as coastal erosion and silting-up, as well as unstable marine landscape.
