By using the beach monitoring technologies such as Unmanned Aerial Vehicle (UAV) and elevation monitoring equipment, the monitoring data of Haiyang beach before and after Typhoon Lekima (No.1909) were obtained, the morphology changes, erosion and accretion variation of beach profiles during Typhoon Lekima landing were analyzed, and the response of beach evolution to the typhoon was discussed. The result shows that beach morphology evolution after the typhoon is mainly including the expansion of the aeolian dune area, erosion of the beach surface in the high-middle tidal zone, micro-topography disappearance and so on. The typhoon mainly affected the beach by erosion, resulting in an erosion volume about 2.43×104 m3, which mainly occurred on the high tide zone. The aeolian dunes were weakly silted, but some of them were eroded seriously. The backshore was weakly silted because of sand deposition from strong wind and alluvial flow. In the middle and low tide zones, beach morphology changes were mainly controlled by the beach surfaces lope, which was manifested as erosion with high slope, weak deposition with low slope, and several small sandbanks formed after the typhoon. On the whole, the typhoon impacts on the beach evolution mainly lead to the sediment budget deficit, and further exacerbated the erosion of Haiyang beach.
