Abstract

The present study is aimed at determining the confidence limits of design wave parameters derived from numerical modeling - for both extremes and operational conditions - over the Central and Western Mediterranean Sea. The paper presents the methodology and results of an extensive validation activity conducted on a chain of medium resolution third generation wave models used for hindcast purposes. The stringent requirements of state-of-art coastal and offshore engineering applications over this area make the adoption of medium or high resolutions hindcast wave and wind models almost mandatory because of the complex coastal geometry, bathymetry and orography that in turn lead to large variations of the design wave parameters even within small regions. The chains of nested meteorological and wave models used in this hindcast study belong to the ETA and WaveWatch III families respectively. In this study the wind and wave numerical models have been run over the past 20 years, with increasing resolutions of the wave models from 0.2° up to 0.04°. The results here presented have a 0.1° resolution for both wind and wave models. The wave data obtained are compared with available measurements from 14 wave buoys in coastal zones in the Central and Western Mediterranean Sea.
