Assessment of Wave Tranquility by Boussinesq Model for Port Development

Abstract

Over the last 40 years, Boussinesq-Type Models (BTMs) became well known and are favoured by the coastal engineering community. This is because of their ability to represent all main physical phenomena, mathematical well posedness and computational ease. A spectral wave model, MIKE 21 SW and a BTM, MIKE21 BW were used in the present study for simulation of wave propagation in offshore region and in the harbour region respectively. Analysis of about 12 years deep water wave data was carried out which became input to the MIKE21 SW model. The model results with existing breakwater were compared with the observed wave heights indicating satisfactory comparison and confirming the successful verification of the model. Finally, wave disturbances in the harbour were assessed for different extensions of an existing breakwater and suitable extension is suggested for the desired wave tranquility in the harbour.
