| Abstract: | Wave-induced oscillations in a circular harbour with protruding breakwaters and narrow mouth are analytically investigated by using a variational method. The effects of the bottom topography of the contiguous external sea are studied, especially as far as Helmholtz resonance is concerned; it has been found that the amplitude of the resonance peak is quite sensitive to the depth variation, while the related resonance wavenumber is more stable. |
