“…Many external factors can trigger harbor oscillations, such as atmospheric pressure fluctuations, tsunamis, earthquakes, wave groups, low-frequency waves, tides, shear flows or vessel-induced bores (De Jong and Battjes, 2004;Park et al, 2016;Gao et al, 2019cGao et al, , 2020Fabrikant, 1995;Shao et al, 2020;Wang et al 2015;Zheng et al, 2021). Based on the analyses for many field measured data (e.g.…”

Influences of topographic variations of the offshore fringing reef on the harbor oscillations excited by incident N-waves with different amplitudes and waveform types are studied for the first time. Both the propagation of the N-waves over the reef and the subsequently-induced harbor oscillations are simulated by a Boussinesq-type numerical model, FUNWAVE-TVD. The present study concentrates on revealing the influences of the plane reef-face slope, the reef-face profile shape and the lagoon width on the maximum runup, the wave energy distribution and the total wave energy within the harbor. It shows that both the wave energy distribution uniformity and the total wave energy gradually increase with decreasing reef-face slope. The profile shape of the reef face suffering leading-elevation N-waves (LEN waves) has a negligible impact on the wave energy distribution uniformity, while for leading-depression N-waves (LDN waves), the latter gradually decreases with the mean water depth over the reef face. The total wave energy always first increases and then decreases with the mean water depth over the reef face. In general, the total wave energy first sharply decreases and then slightly increases with the lagoon width, regardless of the reef-face width and the incident waveform type. The maximum runup subjected to the LEN waves decreases monotonously with the lagoon width. However, for the LDN waves, its changing trend with the lagoon width relies on the incident wave amplitude.

“…However, in some places, it is also observed continuously with small amplitudes. [2], [3] A natural or an artificial basin may offer good conditions of shelter for the open sea, particularly for wind waves (short waves), however both the geometry of the basin and their internal reflections can efficiently amplify the incident long waves, even for those with small amplitudes. So, this phenomenon of resonant oscillations is called seiches, harbour oscillations or harbour surging and is related to specific periods of the incident waves on the structure.…”
