Storm Surge Magnitudes and Frequency on the Central Oregon Coast
There has been little documentation of storm surges along the coast of the U.S. Pacific Northwest (PNW), generated by extratropical storms. A 44-year record of measured tides on the central Oregon coast has been analyzed to determine the hourly non-tidal residuals, which were further analyzed to separate the storm-surge component from the enhanced winter water levels of the seasonal cycle, which can amount to 0.5 m during El Niños. The results document that surge levels have reached 1.4 m, with as many as 15 significant occurrences during a winter, having been greatest during the late 1960s and early 1970s. Although storm intensities and measured wave heights have been increasing over the decades, there has not been a corresponding increase in surge levels and frequencies. Although small compared with surges generated by east-coast Northeasters, the PNW surge events can produce 10s of meters of dune retreat, representing a significant erosion hazard.
