Abstract
The third and fourth order odd velocity moments in Bailard's (1981) cross-shore transport model are broken down into a number of velocity moment terms which predict bedload and suspended load sediment transport rates relating to various interactions between the short (incident) wave, long (infragravity) wave and mean flow components. Field measurements of cross-shore velocities were obtained, using electromagnetic current meters, from morphodynamically reflective, intermediate and dissipative macrotidal beach sites, during high energy conditions. Comparison between the velocity moment predictions and measured transport rates showed that the predictions of the short wave transport were poor, predictions of the long wave transport were somewhat better and predictions of the mean transport were generally good. Both the measurements and the predictions showed that sediment transport processes inside the surf zone of dissipative beaches are dominated by the mean and long wave flow components.
