Experiment on Incipient Motion of Clayey Silt in the Main Channel of Xuwei Harbor, Lianyungang under Wave-Current Action

Abstract:

For two sampling sediment take from the-3m and-5m depth water in the main channel of Xuwei port, Lianyungang, the experiment of sediment incipient motion under wave-current interaction is carried out in a wave-current flume. The results show that the wet density of bed sediment is 1.4 t/m³ and 1.5 t/m³ respectively, the critical incipient shear stress at the bottom of the bed is between 0.21 N/m²~ 0.29 N/m² and 0.35 N/m² ~ 0.46 N/m² respectively; the critical incipient shear stress of sediment from-3m depth water is greater than from the-5m depth water for the same wet density of bed sediment. The results can provide parameters and basis to the research of engineering sediment problem.
