Description
Summary:Record of sea-surface elevation as a function of time at a specific location use an instrument called a buoy. The recording of ocean waves is done at discrete time <br /> <br /> <br /> <br /> <br /> intervals Delta t. Records of these waves can be modeled as the sum monochromatic wave through Fourier series. Fourier analysis can be used to determine the amplitude and phase for each frequency. <br /> <br /> <br /> <br /> <br /> Ocean waves are continuous phenomena, but the records are discretised by the buoy. To avoid misinterpretation due to discrete wave recording, Delta t must be chosen small enough. Any choice of Delta t may lead to the Nyquist frequency and aliasing effects. This aliasing effect must be realized in the calculation of energy spectrum. Furthermore, the wave energy spectrum is calculated using the fast Fourier transform procedure. In this final project, we will compare the energy spectrum of solitary wave and second-order Stokes wave of the same amplitude
