Non-Harmonic Constants

Science / Tides and Currents / Non-Harmonic Constants: Tidal constants such as lunitidal intervals, ranges, and inequalities which may be derived directly from high and low water observations without regard to the harmonic constituents of the tide. Also applicable to tidal currents.

Tidal Constants

Science / Tides and Currents / Tidal Constants: Tidal relations that remain practically constant for any particular locality. Tidal constants are classified as harmonic and non-harmonic. The harmonic constants consist of the amplitudes and epochs o MORE
