Wave hazards on microtidal shore platforms: testing the relationship between morphology and exposure

David M Kennedy, Daniel Ierodiaconou, Adam Weir, Barbara Brighton



Open-ocean rocky coasts are dangerous environments when there is a coincidence of recreational activities occurring in areas of high wave energy. Management of drowning fatalities and near-drowning incidents on these landforms is difficult as traditional approaches to beach safety cannot be easily transferred to rocky shores. In this study, we take a morphological approach to quantifying the relative danger of shore platforms in microtidal regions. Platform elevation and nearshore water depth are key variables in determining the likelihood of wave overtopping of the platform edge. The relationship between these variables is tested along a 70-km-long section of the Otway Ranges coast in Victo..
