Abstract
Turbidity which occurs in a marine construction should be daily controlled. For the management of turbidity control, a numerical simulation of the turbidity dispersion based on the current prediction is useful. However, the commonly-used numerical simulation needs a long computational time for the predictions of nearshore current and wind drift current. In this study, the simplified numerical calculation method was developed with a reef current. In this method, the total current field is predicted by superposing the tidal current and the nearshore current, which are respectively predicted.The proposed method was validated by comparing with the commonly-used full simulation of the turbidity dispersion for the supposed construction sea area. As a result, the proposed method accurately reproduced the full simulation results by taking the tide level variation into account for the tidal current field prediction.
