摘要：

As research on transient harbor resonance induced by the N-wave is very limited, the effect of broken line-type topography inside the harbor on transient harbor resonance induced by the N-wave is studied in this paper. The transient resonance is simulated by a fully nonlinear Boussinesq model, FUNWAVE-TVD. The response amplitudes of various resonant modes in the long and narrow rectangular harbor are obtained by the normal mode decomposition method. The effects of different incident N-wave amplitudes and various broken line-type topographies inside the harbor on the maximum runup and total wave energy inside the harbor are then systematically studied. Results show that for the topography studied in this paper and in the variation range of the incident N-wave amplitude (0.01 m ≤A0≤ 0.07 m), the maximum runup inside the harbor increases with increasing incident N-wave amplitude, and decreases with increasing mean depth of the water. In addition, the existence of a broken point can slightly reduce the maximum runup. In general, the total wave energy in the harbor increases linearly with increasing mean depth of the water.
