Implication

Field observations reveal landward and seaward sediment flux in intertidal mudflats, indicating the role of tidal surges and waves.

Key Points

  • Sediment transport is significantly affected by tidal surges and wave activity, with a distinct two-layer structure identified.
  • Strong tidal surges enhance landward flux and are observed in the upper water layers, while seaward flux occurs in the near-bed layer.
  • Elevated suspended sediment concentrations during flood events contribute to landward flux, accounting for about 30% of total ebb sediment flux.
  • Wave shear stress plays a critical role in resuspending sediment during high tide, facilitating sediment transport dynamics.
