风暴潮作用下泥沙运动和岸滩演变研究综述

对风暴潮作用下泥沙运动和岸滩演变的研究进行了归纳、总结和评述,包括风暴潮作用下泥沙输移运动研究、泥沙运动相位滞后规律、风暴潮作用下岸滩演变规律以及作用后风暴剖面的恢复、海平面上升对岸滩演变的影响,探讨了风暴潮条件下Bruun法则的适用性。为了对风暴潮作用下泥沙运动、滞后效应和岸滩演变规律的机理有更加确切地把握,开展相应的实验室研究势在必行。而风暴潮的概化模拟是后续研究需要突破的方向。在海平上升的情况下,Bruun法则可能不再适用于风暴潮作用下的岸滩侵蚀研究。

Review of sediment transport and beach profile changes under storm surge

Research of sediment movement and beach profile evolution under storm surge are summarized and reviewed,including sediment transport movement under storm surge,the relative lag phenomenon of sediment movement,the beach profile evolution under storm surge and the recovery of storm profile,the influence of sea level rise on beach profile evolu-tion and exploring the feasibility of Bruun rule under storm surge.In order to grasp it more accurately about sediment movement under the storm surge,the hysteresis effect and the mechanism of the regular pattern of beach profile evolution,it is imperative to carry out the corresponding laboratory research.As the generalized simulation of storm surge is the direc-tion of further research to breakthrough,Bruun rule may no longer be applicable to the beach profile erosion research under storm surge when the sea level rises.
