Transformation of Water Wave Spectra into Time Series of Surface Elevation

Spectral wave modelling is widely used to simulate large-scale wind–wave processes due its low computation cost and relatively simpler formulation, in comparison phase-resolving or hydrodynamic models. However, some applications require a time-domain representation of sea waves. This article proposes methodology transform the spectrum into time series water surface elevation for that ocean The proposed method uses generated phase inverse Fourier turn elevation. consistency then verified. results show it capable correctly transforming spectrum, significant height resulting within 5% input spectrum.
