Abstract

A hydrodynamic model of the Baltic Sea based on the Princeton Ocean Model was appliedin analyses of extreme storm surges along the Polish Baltic coast. When the applicability ofthe model in cases of high-amplitude and rapid water level fluctuations, such as those observedat the beginning of November 2006, was tested a good fit was obtained between observed andcomputed data. The model correctly predicted the hydrodynamic situation; it also generatedrelatively good simulations of water-level variations. The best fit between the numerical calculationsand readings from the sea-level gauges was obtained for Gdańsk Nowy Port, while onlyslightly worse agreement characterized Świnoujscie and Ustka.
