Abstract
A field observation, comprising bottom mounted instruments for near-bottom currents and suspended sediment concentrations, was carried out for 1-month at Tama River mouth in Tokyo Bay. The measurements have captured sediment resuspension during extreme wave conditions associated with typhoon that passed over Kanto district in the early September of 2007. The sediment resuspension was caused primarily by waves at the monitoring site and combined current-wave bottom shear stress reached 0.9 Pa. Based on the SS-flux analysis during the recording period, the net suspended sediment transport at the site was towards the SW or outer Tokyo Bay.
