Dynamics simulation of bottom high-sediment sea water movement under waves

Xueyi YOU , Wei LIU , Houpeng XIAO ,

Frontiers of Structural and Civil Engineering 2009, Volume 3, Issue 3,   Pages 312-315 doi: 10.1007/s11709-009-0037-y

Abstract: The movement of bottom high-sediment sea water under water waves, especially that of the high-sedimentwater layer close to the sea bottom, is important to the resuspension and settlement of sediment.Supposing that the high-sediment sea water is a Newtonian fluid, based on Navier-Stokes (N-S) theory,The results show that the movement of sediment water is very different from that of sea water, whichwater-sediment water interface movement on the air-water interface is not obvious.
