Abstract

The stress condition in the sea bed such as effective stress and hydrodynamic condition were measured in the surf zone to understand the detailed mechanism of local and temporal sediment movement. Analysis of the measured data suggests that the large effective stress drop and strong flow in the onshore direction when the wave crest passes are the possible cause for the sand movement in the surf zone. It is also found that the sea bottom elevation change can be evaluated from the effective stress in the sand by a simple equation. The effective stress sensor used in the field measurement was proved to be useful in estimating local and temporal sediment transport.
