Abstract
Suspended sediments in estuaries play a significant role in understanding ecological and engineering problems. However, our knowledge for the transport processes of suspended sediments is insufficient, because the flow structures are very complex. To shed light on the effects of wind on sediment transport in Ohtagawa estuary, long-duration observations were carried out, using acoustic Doppler current profiler. In usually, the direction of the sediment transportation was toward upstream for the restricted freshwater discharge. When the wind blows downstream, the suspended sediment intrusion is encouraged. In flooded time, the direction of the sediment transportation was toward downstream.
