Tide power and sea-level predictions rely on harmonic analysis of astronomical constituents combined with hydrodynamic modeling of coastal regions.
The claim states that tide predictions require harmonic analysis of astronomical constituents and hydrodynamic modeling. Paper [8] discusses using harmonic analysis on tide gauge records to understand tidal constituents and account for astronomical nodal cycles. Paper [11] explicitly leverages hydrodynamic modeling and harmonic analysis to evaluate tidal harmonic constituents and water surface elevations. Both sources support different facets of the claim, and no papers refute it.
