Assessment of Sudden Siltation in port area based on numerical simulation

Abstract During the typhoon period, sudden silting is easy to happen in the port area, which will affect the normal operation of the ship. It is an important reference for port maintenance to evaluate the Sudden Siltation after typhoon. In this study, a coupled mathematical model of wave, tidal current and sediment is established to simulate the sudden deposition of Ruoshan port area under the action of typical typhoon. The results show that the sediment concentration in the typhoon period is much higher than that in the normal weather because of the larger current velocity and the obvious wave action. The research results can provide design support for dredging and maintenance of Ruoshan port.
