The study looked at how different management strategies affect a sandy beach's response to storms and recovery. Researchers used high-tech surveys and videos at Biscarrosse beach in France. They found that in winter, the beach eroded and the dunes moved back, with different parts of the beach responding differently. In the spring and summer, the beach started to recover, but areas in front of seawalls took longer to rebuild. Sediment movement along the beach varied, with managed sections relying more on side-to-side movement. Rip currents in front of seawalls caused sediment to wash away, slowing down recovery. Seawalls limited exchanges between the beach and dunes, leading to faster erosion.
