Classic Tidal Analysis Methods

Classic tidal analysis methods involve separating various tidal constituents (such as lunar tidal systems, solar tidal systems, etc.) from measured tidal level records before performing harmonic analysis. Algorithmically, this process calculates the amplitude and phase angle for each tidal constituent, followed by astronomical correction to obtain harmonic constants. Implementation typically utilizes Fourier transform techniques and least squares fitting to compute tidal constituents. This harmonic analysis enables prediction of tidal variations over specific periods and characterization of regional tidal properties.
