北戴河西海滩波浪动力与人工养护沙滩侵蚀 原位监测研究.

This paper measured the evolution and wave data of the nourished beach, estimated the contributions of erosion amount and effective wave height to beach erosion by taking the West Beach of Beidaihe as an example. The results show that the beach has an overall erosion trend after the nourishment, with the maximum erosion height of 1.7 m. The cumulative influence of the wave height on the beach erosion is an exponential distribution. Although large waves with lower recurrence frequencies (significant wave height>0.6 m) can cause greater beach erosion, their cumulative contribution to the total beach erosion is only about 25%, while the contribution of regular waves with heights of 0.3 m to 0.6 m can reach 75%. This study can provide reference for maintaining the quality of artificial beach, and beach evolution prediction after artificial nourishment. [ABSTRACT FROM AUTHOR]
