| 摘 要： | 通过卫星遥感图片、现场实测和室内实验,对黄骅港外航道的大风骤淤机理进行了综合分析。认为黄骅港大风骤淤是由于外航道两侧破波带附近滩面泥沙大量悬扬、落淤造成的,沿堤流不是外航道骤淤的主要因素。在波浪作用下,泥沙运动存在明显的三维特征,应重视现场实测工作并尽可能采用三维数值模型,谨慎对待采用遥感卫片和二维数值模型得到的计算结果。

| Abstract: | Careful analysis shows that for wave dominate climate,the suspended sediment concentration is controlled by waves and showed large vertical gradients.The high deposition rates in the access channel of Huanghua Port is caused by high waves in storm events.Remote sensing and 2D horizontal numerical modeling need to be used with caution due to their lack of vertical resolution.It is recommended to apply field measurements and 3D numerical modeling whenever possible. |
