文摘

The instantaneous morphodynamic response of the low-lying sediment-limited barrier island investigated in this study to 96 h of hurricane impact was found to be far more complex than suggested by pre and post storm surveys alone. Results from process-based numerical morphodynamic models (XBeach and CSHORE) suggest that the most significant change in bed level was associated with the 10-hour inundation regime (onshore directed flow); followed closely in significance by the storm surge ebb regime (offshore directed flow).
