Title: Stability analysis and protection methods for the Huangcheng Beach in Xiangshan County
Abstract: In this paper, a parabolic model was used to study the stability of the Huangcheng Beach, and the impact of the seawall on the beach was analyzed, and the protection methods were figured out. The results show that erosion was found in the north part of the Huangcheng Beach, and the planform of the Huangcheng Beach hasn′t reached the static equilibrium. The northern seawall was too close to the seaward, so that the backshore dunes formed. The most important sources of supply for the beach, were isolated and disappeared completely. Furthermore, the interaction of spring tide drowning the bottom of the seawall and the breaking waves in the front of seawall made water flow of beach face and sediment movement intensively. Therefore, the scour in the front of seawall happened. Finally, the best countermeasure to prevent the erosion of beach was to use the appropriate beach nourishment after removing and rebuilding the northern part of seawall. Through the study on the stability of the Huangcheng Beach, the impact of seawall on the beach can be well understood. This can provide some scientific basis for the rational development of Zhejiang headland bay beach resources, and construction of coastal protection engineering.
