Impact of storms on beach erosion: Broadbeach (Gold Coast, Australia)

The present study aims to quantify Broadbeach response to storm events in order to assess the ability of this beach to withstand extreme events and to recover during periods of lower wave energy. From March 1, 2006 to Jul 10, 2006, 35 accurate subaerial beach surveys were undertaken. During this per...

Description
Summary:The present study aims to quantify Broadbeach response to storm events in order to assess the ability of this beach to withstand extreme events and to recover during periods of lower wave energy. From March 1, 2006 to Jul 10, 2006, 35 accurate subaerial beach surveys were undertaken. During this period, Broadbeach experienced three storm erosion events. The first storm was a hybrid-cyclone which generated one of the most energetic wave conditions on the Gold Coast of the past 30 years, with measured offshore significant wave height reaching 5.3 m, and maximum wave height 10.7 m at the Gold Coast Seaway buoy. During the two other storm wave events, wave conditions were much less energetic than during the first storm, with significant wave heights ranging from 2 to 3 m. The early March extreme event resulted in a 48m super( 3)/m erosion of the subaerial beach and a 70 m seaward migration of the outer bar in just a few days.
