Wave Processes and Overwash Hazard on a High-Energy Rock Platform

摘要: The Figure Eight rock platform is a high visitation and hazardous natural attraction located about 1 hour south of Sydney, Australia. The site features unique rock pools that have been weathered into the sandstone platform over thousands of years, which attract local and international visitors who swim in the pools and have their photo taken. A rapid rise in visitation and visitor injuries has prompted an investigation of wave processes and overwash hazard at the site. The method includes morphology and process measurements, and camera monitoring to develop a time series dataset of platform overwashing to analyse in the context of tide and wave conditions. The overall objective of the study is to refine and verify a predictive model for overwash hazard at the site to improve the management of visitor safety.
