Abstract
Previous works have noted that under high energy conditions the inner surf zone is dominated by infragravity wave components. Time-series analysis is made on data from Llangennith beach (S.Wales, U.K.) with the aim of discerning a mechanism for sediment transport at these frequencies. In this situation the major mechanism for suspension of sediment is deemed to be an offshore directed velocity associated with the troughs of incoming long waves. Analysis of third order velocity moments yields a similar prediction, and points toward velocity skewness as a significant factor in associating this hydrodynamic component with the observed suspended sediment concentrations.
