Both short-term and long-term morphodynamics of sand barrier systems forced by moderate storm conditions have been studied significantly in the literature. However, the dynamics of the emerged beach – from a water depth of ≈ 1.5 m below the lowest tide level to the back-barrier – remain scarcely documented. This is even more striking when looking at the impact of typhoons to the shoreline. In this context, this study aims at better understanding by field measurements the morphologic changes of an emerged beach when it is struck by one typhoon, successive typhoons or the combination of a whole season of typhoons with the winter Monsoon season. A comprehensive monitoring of nearshore hydrodynamics and beach morphodynamics was per-formed in the Wan-Tzu-Liao barrier, a 8 km long sandy segment along the south-westernmost Taiwan coast (Figure 1). There, hydrodynamics were measured from October 2011 to Septem-ber 2012, recording a full Monsoon (strong wind velocity = 9.2 m/s in average and moderate wave about H 1/3 = 1.4 m and T m = 6.4 s in average), an intermediate spring period (fair-weather wind and average waves about H 1/3 = 0.57 m and T m = 5.84 s) and a whole summer season (fair-weather wind and waves alternating with typhoon-waves up to ≈10 m in less than 20 m of water depth). In parallel to hydrodynamics, morphodynamic surveys were performed each week during winter and just before and after each storm during summer.
