Temporal variation of resuspended matter for one tidal cycle in the Hiuchi-Nada area

The observed relation between the vertical distribution of suspended matter and the size distribution of bottom sediment in the Hiuchi-Nada area indicates that a turbid bottom water layer exists above the bottom when the bottom sediment is of silt size. The turbid bottom water is thought to be produced by resuspension of bottom sediment. Measurements of the temporal variation of resuspended matter and water movement near the bottom was carried out for one full tidal cycle at an anchored station. The concentration of resuspended matter reached a maximum at the time of strongest ebb and flood flow.
