我国河口和海岸多为粉沙和淤泥所覆盖,在潮流和波浪共同作用下,泥沙极易悬浮和输移.因而对潮流和波浪共同作用下挟沙能力规律的研究,在学术上和应用上均具有重要意义.然而由于问题极为复杂,过去的研究,一般局限于经验分析,尚缺少理论上的阐述.在建立经验关系时,一般都将波浪轨迹质点速度与潮流速迭加值作为综合动力因子.由于此两种 Most of the estuaries and coasts of China are covered by silt and silt, and under the combined effect of tidal current and wave, the sediment is easily suspended and transported, so the law of sediment carrying capacity under the combined effect of tidal current and wave has been applied academically and applied However, due to the complexity of the problem, past studies are generally limited to empirical analysis, and lack of theoretical elaboration .When establishing empirical relationships, the velocity and tidal velocity integral of wave trajectories are generally used as a comprehensive Motivation factor. Because of these two
