STUDY ON RE-SUSPENSION PROCESS OF SEABED SEDIMENT INDUCED BY WAVE

Wave is the main factor to initiate sediment resuspension. In this paper, we presented a case of wave-induced sediment re-suspension under the wave of 15cm in height. The equipment of ASM-IV is used to establish the correlation between the suspended sediment concentration and the turbidity measured by ASM-IV. In this article, we quantitatively calculated the total amount of suspended sediment induced by waves, and the part caused by liquefaction as well as their proportion to the total amount. Results indicate that liquefaction induced by waves is the main cause of sediment re-suspension, which accounts for 76.4% of the total. The work provides an important reference to the further study of the wave induced re-suspension.
