The development of a new tool to analyse historic beach profile data collected during the ex-state government department Coastal Observation Program – Engineering (COPE). The tool analyses monthly coastal profiles against extreme wave and water level statistics to assign a return period to any observed erosion events. The outputs are a statistical distribution of frequent (i.e. between 10-50 year ARI) return period erosion estimates. These are used to cross-check erosion modelling results against evidence-based data.
