Abstract
A combination of observations and modeling of wave-and current-related sediment transport at the ebb-tidal delta of Ameland, The Netherlands, has been used to examine the dominant sediment transport contributions shaping the ebb-tidal delta. The calibrated model shows a good comparison with the observations for a range of conditions. The results show distinctly different transport modes and directions for current and wave-dominated conditions respectively, with a significant contribution owing to the skewness of the waves emphasizing the importance of wave non-linearity in shaping the ebb-tidal delta.
