Seasonal morphological response of an open sandy beach to winter wave conditions: The example of Biscarrosse beach, SW France [link]Paper  doi  abstract   bibtex   
18 months of at least bi-weekly topographic surveys have been conducted on a 700 m stretch of the meso- to macro-tidal Biscarrosse beach, France. Here we focus on the impact of the short-term dynamics of the beach (a few days) on the seasonal winter response of the beach. The beach was surveyed intensively during two winter seasons and the results indicate that despite similar pre-winter morphology but very contrasting energy levels (the first winter season being 1.7 times more energetic than the second winter season), the sediment budgets over the two winter periods were very similar as well as the cross-shore dynamics of the extracted proxies associated with the dune foot and the berm. The data collected suggest that this may be explained by the sequence of erosion/recovery events driven by hydrodynamic conditions (as the water level and energetic conditions), and sediment transport. Thus, during the first winter, post-storm recovery was effectively driven by energetic conditions while during the second winter, inter-storm conditions did not allow the initiation of recovery in between the storms. Apart from the control from wave conditions, the seasonal beach response is also discussed within the framework of storm chronology and tidal range.
