Extreme storms can cause rapid morphological changes that pose high risk to society. Semi-empirical and process-based models often are used to simulate storm-induced coastal processes. However, there are few observations of surfzone waves and currents during extreme storms. Therefore, parameterizations often are calibrated by minimizing model-data errors for pre- to post-storm bathymetric and topographic changes, and the accuracy of the simulated processes during the storm is unknown. Here, surf, swash, and dune observations collected near Duck, NC, USA, will be used to investigate wave processes and dune erosion during the passage of recent Hurricanes.
