Abstract: By taking the Xinghai Beach in the Lingshan Bay of Qingdao as the study object, the evolution characteristics of beach shoreline after construction of the Xingguang Island are analyzed by using multi-temporal remote sensing images and the changes of beach profile before and after storm seasons are studied by comparing two-time measured high-precision topographic data and simulating numerially the beach profiles. The results indicate that after construction of the Xingguang Island the sediment transport along the coastline is distinctly characterized with an accumulative state along the southwestern shoreline and an erosional state along the northeastern shoreline, the topography of the river channel at the river mouth is mainly controlled by the influence of runoffs so that the beach evolution at both sides of the islane is affected significantly, and the intensity of sediment siltation at the east side becomes stronger than that at the west side due to that the sediment transport along the shoreline is blocked at the river mouth. From the profile characteristics, the slope of beach surface within the wave-influence area west of the Baiguoshu River behind the Xingguang Island is stable and the results from both the numerical simulation and the field measurement show that the changes in average elevation of beach before and after summer and autumn seasons are less than 0.2 m. With the hydrodynamic force strengthening eastward at the coastal segments outside the wave-influence area, the profile morphology changes from a normal wave profile (upper siltation and lower erosion) into a storm profile (upper erosion and lower siltation).
