Abstract


We studied resonance in the Venetian Port of Chania, a 14th century historic monument, which frequently exhibits large wave motions in its basin with flooding of its docks. We measured time histories of surface elevation and currents off the harbor for a period of two years and also measured wave elevations at one location inside the Port. Offshore, we recorded maximum Hs= 4.1m with Ts =9.2s. We employed a Boussinesq-type model COULWAVE to explore resonance and determined the resonant frequencies for the entire basin. We also examined the effect of a past proposed breakwater extension design on the resonant frequencies and respective modes. We conclude that the overtopping observed under storm conditions may not be the result of harbor resonance but the little protection of the existing breakwater sheltering the entrance.
