Mechanism of suspended sediment transport in Xishamen
摘要
Abstract
Based on the dynamics measurement of water levels, current velocities and suspended sediment con⁃centrations in Xishamen, the transport flux of suspended sediment was calculated by the flux decomposition meth⁃od, and the space⁃time distributional characteristics were analyzed. The results show that the advection plays a sig⁃nificant role in the regions and the second factor is the tidal pumping effect. The dynamic mechanism of main items was discussed in term of tiding, velocity and suspended sediment concentration process. The conclusion shows the Euler residual current effect is determined by tidal power. The Stokes current is influenced by the nonlinear effect of tide and wave. The tidal pumping effect is induced by the bottom sediment suspended, tidal dissymmetry and con⁃centration diffecence.关键词
