“…In the 1-D problem of the unidirectional wave train, as in Lyu et al. (2021), the evolution equation of is numerically solved in a spatial step by the pseudo-spectral method. Based on the periodicity of the wave envelop in time and space, the partial differential term in the evolution equation can be transformed into a more concise form by using Fourier transform.…”

“…Similar to Lyu et al. (2021), we integrate in (2.19) at each step from offshore to onshore, assuming periodic boundary conditions in time, and construct the surface elevation in a discrete 2-D + T form. Equation (2.19) considers the contribution from first order to second order and second harmonic.…”

“…Wave focusing: Wave energy may be concentrated in a small area because of wave trapping, refraction, and re ection, such as wave-current interaction; wind force; bottom topography in uence, etc. [11][12][13]. e modulation instability, also known as Benjamin-Feir instability [14], has been accepted by many researchers to explain the occurrence of freak waves.…”
