摘要
Beach response to storms is a complex process. We used the continuous images taken by the Argus video monitoring system and analyzed quantitatively the response of Dongsha beach to storms in the aspects of beach geomorphology, profile, beach shoreline, and beach width. We quantified the beach response to two continuous storms Malakas and Chaba, and discussed the factors affecting the response. The results show that the average value of beach volumetric change after the storm Malakas was -73.75m3/m, and that after storm Chaba was -54.56m3/m. Storm Malakas caused the average retreat of 14.75m of entire beach shoreline, and that by Chaba was 10.91m from the shoreline state before the two storms. Therefore, interaction among the nature of each beach, external dynamic factors, and human activities complicated the responses to the two continuous storms in the Dongsha beach.
