  • The analysis of directional wave spectra from current and pressure measurements

    Creator:
    Lin, Li-hwa
    Abstract:
    Directional wave spectra have been estimated in this study based upon simultaneous subsurface measurements of current and pressure. Two previously developed methods, the stochastic and deterministic approaches, have been reviewed and restudied. It is demonstrated by means of the Correlation Theorem that the stochastic and deterministic approaches are, under certain...

  • Simulation of random, nonlinear wave forces on a circular cylindrical pile

    Creator:
    Tuah, Hang
    Abstract:
    Two types of linear random wave simulation methods are investigated; viz., (1) Deterministic Spectral Amplitude (DSA) and (2) Nondeterministic Spectral Amplitude (NSA). These linear simulations are extended to second-order in a perturbation expansion in the frequency domain by utilizing a Fast Fourier Transform (FFT). The nonlinear interaction matrix for waves...
