Coupled Field Measurements and Numerical Modeling of Harbour Resonance at Marina di Carrara

This paper presents initial results from field observations of harbour resonance at Marina di Carrara harbour (Italy) within a research project commissioned by the local Port Authority. The measurement station is operational since October 2005 and provides the Port Authority with immediate and important information on the accessibility and navigation of the harbour, including real-time monitoring of the wave field both outside and inside the harbour. Observations carried out in the winter 2005/2006 are analysed by means of well established and relatively new techniques, demonstrating some of the non-stationary and non-linear features of the resonant process. Initial measurements are compared with predictions by a numerical wave model based on Boussinesq-type equations. The model is able to describe both the non-stationary and the non-linear features of the process.
