摘要

A common approach to determining the potential damage of a coastal storm has been to focus on flooding impacts and the use of stage-frequency analysis as the primary means of determining storm severity. Such an approach appears to have failed in quantifying the coastal erosion and flood impacts generated by the northeaster of 12-16 November 2009. Three indices that have been proposed in the literature as a means to quantify the damage potential of northeasters have been evaluated through a comparison of six significant extratropical storms. Each index was found to accurately rank the severity of observed storm erosion/damage. Through an assessment of the individual variables of each index, storm duration was found to be highly correlated with damage potential followed by maximum significant wave height and water level.
