REFLECTION AND TRANSMISSION OF WATER WAVES PAST A VERTICAL THIN BARRIER IN A TWO-LAYER FLUID

The interaction of water waves for both surface- and internal-wave modes with a rigid vertical thin barrier in a two-layer fluid was examined. The theoretical solutions were obtained by an eigenfunction expansion method for the reflected and transmitted energies for waves of both modes. It is shown that for the incident wave of each mode, the energies of the reflected and transmitted waves of the other mode are equal. The reflected and transmitted energies, as well as the hydrodynamic force on the barrier due to incident waves of both surface- and internal-wave modes were computed for two types of structures which are a bottom-touched barrier and a surface-piercing barrier respectively. The results indicate that density stratification can have a relative large effect on the reflection, transmission and hydrodynamic characteristics of the barrier over a wide range of frequencies. In particular, when an end of the barrier is located on the interface of the two-layer fluid, such an effect is very strong.
