Abstract: The narrowing of beach berm and steepening of backshore slope are important characteristics of storm sandy beach profile under the influence of storm wave action and the recovery during normal waves is closely related to the mutual feedback among the nearshore hydrodynamic force, sediments and geomorphology. Based on the surveyed data obtained from beach profiles in Puqian Bay before and after Typhoon Kompasu and surveyed data during the normal wave period, the recovery characteristics and the main impact factors of sandy beach recovery after typhoon storms were analyzed with XBeach model tests. Result showed that typhoon storm waves cause supratidal erosion and intertidal accretion in the profile. The slopes on both sides of the berm point decreased under the influence of typhoon storm, whereas the sediment in the supratidal zone was increased and the slopes on both sides of the berm ridge were gradually steeped and moved to land under the cumulative effect of post-typhoon storm waves. The recovery efficiency of berm elevation is higher than that of beach berm platform width and the overall recovery efficiency of the intertidal zone is the fastest, while recovery efficiency above the average high tide level is slower. The dominant role of waves in the restoration efficiency of wave-controlled profile shows mainly in the sediment transport flux caused by wave height and wave asymmetry. The bottom bed shear stress and return flow velocity during the flood tide period were greater than those in the ebb tide period, which promoted the net sediment transport to the shore.
