Beach nourishment projects in Beidaihe successfully combat erosion, ensuring coastal protection.
Two beach nourishment projects were conducted in Beidaihe in 2009 and 2013. Monitoring data revealed that erosion was severe after the first project, indicating a need for further restoration. Both projects were successful, with the second project being more effective based on sand volume remaining after nourishment. Continuous monitoring of the beach is recommended to assess project effectiveness and understand factors influencing beach nourishment.
