Fig. 1. The dunes and their erosion during the extreme storm event.

Caption

(A) Vegetated dune (VD). (B) Bare dune (BD). The different camera angles reveal beach berm and dune apex features, but the initial profiles for VD and BD were equivalent throughout the 104-m length of the flume. (C) VD profile evolution. (D) BD profile evolution. Initial profiles were equivalent at time zero as denoted by dotted lines (shown here only within the vegetated region from 72.5 to 80 m in cross-shore position). Colored lines depict the profiles at the end of the numbered time intervals. (E) Erosion during specified time intervals (bars) and cumulative erosion (lines). (F) Timeline (continuous) of major events in BD versus VD profile evolution. 2,3Refer to Figs. 2 and 3 for details.
