Research Abstract |
Suspended sediments in estuaries play a significant role in understanding ecological and engineering problems. To shed light on the effects of river discharge, tidal range and wind on sediment transport, long-duration observations were carried out in the Ota floodway, using acoustic Doppler current profilers. In usually, the direction of the sediment transportation was toward upstream by the tidal straining for the restricted freshwater discharge. Furthermore, transverse sediment transports on tidal flats were demonstrated. In addition, the variability of tidal flat sediment was clarified.
