Abstract

The formation of an inner nearshore bar was observed during a 19-hour high-energy event at the sandy beach of Vejers, Denmark. Suspended sediment transport and cross-shore sediment transport gradients were obtained from a cross-shore array of sensors in the inner surf zone. These process measurements showed that a divergence in sediment transport occurred at the location of the developing trough, and observed gradients in cross-shore net sediment flux were consistent with the morphological development. The main cause for the flux gradients were cross-shore gradients in offshore-directed mean current (undertow) speed which depended upon local relative wave height and local bed slope
