The results are as follows. (1) The remarkable multiple scales of wave energy oscillations exist in the surfzone.

Understanding these sandbars is critical to study of beach erosion and climate-related sea level rise, but the surfzone is a notoriously hostile research environment.
It is shown from the study results that the sediment flux and its vertical distribution in the nearshore zone are affected by the relative position of surfzone and the beach topography.
