Study on Influences of Fringing Reef on Harbor Oscillations Triggered by N-Waves

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