Abstract

In the present work a non-linear dispersive wave model is developed for the description of the propagation of seismic origin water waves inside harbours. The model is based on the Boussinesq type of equations. As input at the offshore boundary an existing linear dispersive wave model for tsunami generation and propagation in deep water is used. The Smagorinsky approximation is used for the representation of the damping by eddies smaller than the computational grid size. Energy loss due to bottom friction and wave breaking are also included. The model is used for the calculation of the resonant response of harbours. The results are compared with analytical solutions from linear wave theory. Seism
