摘要

摘要: The rotary ring flume is used to study the silty sand movement in a periodic alternating current. Characteristics of sediment movement of different coasts in the tidal current are summarized. More detailed analysis of erosion-sedimentation function in a numerical simulation is made. The equilibrium sediment concentration is advanced. Based on the equilibrium sediment concentration, the seabed erosion-sedimentation index is derived and the seabed erosion-sedimentation calculation is analyzed. The seabed erosion-sedimentation index is used to calculate the seabed evolution of Yangshan sea area and a good agreement with field measurements is obtained.
