黄骅港位于中国渤海淤泥质海岸，是一个由三个长13.32 ~ 23.4公里的防波堤组成的半封闭式港口，集煤炭港和综合港于一体。频繁的大风在入口处和外海航道造成了厚厚的沉积。在本研究中，使用Delft3D软件的二维深度平均水平版本，建立了水动力悬沙输运和河床演化模型。该模型通过潮位、潮流和悬沙浓度等实测数据进行了验证。应用该模型预测了三种不同风场条件下的悬沙输运以及大风和波浪的短期形态演变。大风引起的海流和波浪使悬浮沉积物浓度大大增加。2003年和2012年大风及其诱导波的预测表明，悬浮沉积物是由沿防波堤的水流驱动的，可以很容易地…
AbstractHuanghua Harbor, a semiclosed harbor with three 13.32–23.4 km-long breakwaters forming a coal port and a general port, is located on the silt-muddy coast of the Bohai Sea in China. Frequent gales cause thick sedimentation at the entrance and in the outer waterway. In this study, a two-dimensional depth-averaged horizontal version of the Delft3D software is used to formulate a hydrodynamic suspended sediment transport and bed evolution model. This model is validated by field data, including the tidal level, the tidal current, and the concentration of suspended sediment. The validated model is applied to predict the suspended sediment transport for three different wind scenarios and the short-term morphological evolution from a gale and a wave. The suspended sediment concentrations largely increase from gale-induced currents and waves. The predictions from the gale and its induced wave in 2003 and in 2012 indicate that suspended sediments are driven by the current along the jetties and can be easily...
