Abstract

A new method of classifying storms based on the erosion potential of its associated waves and water levels is presented. The Storm Erosion Index (SEI) and the related Peak Erosion Intensity (PEI) Index differ from traditional measures of storm magnitude in that they account for the joint occurrence of storm waves and elevated water levels in a physical way. Both the PEI and SEI are time dependent functions of the local water level and incident wave energy, and can be used to either hindcast historic conditions based on observational data, or predict future conditions based on existing hydrodynamic forecast models. In this study historical storms are analyzed based upon both traditional (surge, wave height, and wave energy) and non-traditional (PEI and SEI) measures of intensity, and then compared to observed shoreline changes.
