Description

The management of coastal hazards is closely dependent on coastline retreat resulting from storm erosion, which is one of the most important coastal phenomena that needs to be accurately quantified. A rigorous albeit complex Joint Probability Method (JPM) for estimating storm erosion volumes proposed by Callaghan, et al. (2008) has been extended to include confidence limits and process-determined coastal erosion (using the numerical beach profile change model SBEACH). We discuss the pros and cons of the physical and numerical implications resulting from replacing Kriebel and Dean (1993) analytical model within Callaghan, et al's method with SBEACH.
