摘要:For the deserted estuary without sediment inflow, ocean hydrodynamic has become the main force for coastal erosion. This paper utilizes wave-tide gauge and current meter to monitor the hydrodynamic within the experimental area and also, turbidity meter is used to conduct indirect monitoring to the sediment concentration (the corresponding relation between the turbidity value and the content of suspended particles in the water is pre-calibrated indoors). Statistical means is adopted to calculate the correlativity between the turbidity and hydropower factors, such as wave height, tide height and flow meter which are determined on site and then the determining factors for sediment incipient are obtained. The conclusion is that the eddy and turbulent flow caused by broken wave constitute the main dynamic factors for the sediment incipient and the incipient velocity mainly comes from the flow rate of the eddy and turbulence resulting from the broken wave.
