Coastal sediment siltation has long been a major problem for design and construction of coastal large-scale ports in the world. Silty sediment siltation often occurs in coastal waterways of China especially during storm events, in which silty sediment is stirred up from the seabed and re-suspended into the water column by storm-induced waves, and transported into the waterways by currents in three forms of suspended load, bedload and sheet-flow load. This study is to derive a generalized model for estimation of sediment siltation rates under both non-storm and storm conditions based on 6-year field data collected in the outer navigation channel of Huanghua Harbor. The sediment siltation data were collected by directly measuring the seabed elevation changes along the port navigation channel from 2002 to 2007. In analyzing the field data collected, a semi-empirical model between effective wind energy and sediment siltation rate is also presented, and found that the newly derived model yields satisfactory agreement with the siltation data collected during the coastal storm events.
