Résumé : |
In the present study, the SWAN model was employed to estimate the wave field on an open sandy beach at the west coast of Portugal. It is the purpose of this work to evaluate the sensitivity of nearshore wave propagation modelling to (i) the wind field resolution, (ii) the type of information used at the offshore boundary to drive the simulations, and (iii) the whitecapping formulation used by the wave model. Wave measurements from an acoustic Doppler current profiler (ADCP) sensor moored in 17 m depth (datum), and operating during a rather stormy period, were used to model comparisons. The comparison showed that no significant differences in the results were found between the two wind field resolutions tested and also that an improvement was observed when the model of van der Westhuysen et al. (2007) is used for the whitecapping dissipation, instead of the default formulation by Komen et al. (1984). |
