| 摘 要： | 飞雁滩海域是1964—1976 年黄河刁口河流路入海区域。根据地形和断面水深监测资料,阐述了该岸段流路废弃后的岸滩侵蚀特征和地貌变化。研究结果表明,刁口河流路废弃后飞雁滩海岸向海凸出的地形特征,是造成该岸段强烈侵蚀的重要原因。进一步结合波、流动力的对应分析认为,波浪以掀沙为主,潮流以输沙为主,波浪和潮流的联合作用是飞雁滩海岸侵蚀的主要动力机制,其中潮流主要通过余流携沙外输,造成近岸泥沙亏损。

| Abstract: | Feiyantan was the discharge area of Diaokou River distributary of the Yellow River during the period of 1964 to 1976. The coastal erosion feature and morphological evolution at the Feiyantan coast are studied in the light of the topography and section depth, and the corresponding dynamics of wave and current. Results indicate that the protruding topography left after the Diaokou River distributary was abandoned is the main cause of strong coastal erosion. Further research suggests that waves start up the sediment and the tidal current transports it, and the waves and tidal current are combined to be the dominant dynamic mechanism of coastal erosion, in which the tidal residual current takes and transports the sediment outward, thus causing the sediment to wane in the coast. |
