Abstract

In this paper, oblique wave trapping by a poroelastic floating plate is analyzed. The poroelastic horizontal plate is floating over uniform bottom bed, finitely extended and positioned at a finite distance away from an existing rigid seawall. Due to the presence of the poroelastic plate, a major amount of incoming wave energy will be dissipated and there will form a calm region in the leeside of the plate. The wave reflection and dissipation coefficients associated with the wave scattering will be analyzed for a variety of wave and structural parameters. It is observed that the poroelastic plate can act as an effective wave energy dissipator.
