World Tides

GUI-based program for tidal analysis and prediction using up to 35 tidal harmonic constituents.

World Tides is a general purpose program for the analysis and prediction of tides. Using least squares harmonic analysis, it allows the user to decompose a water level record into its tidal and non-tidal components by fitting between 5 and 35 user-selectable tidal frequencies (tidal harmonic constituents). The constituents can then be saved to allow future prediction of tides. Non-tidal water level displayed in graphs provide a complete depiction of storm surge and storm tide (storm surge plus astronomic tide) during tropical and extratropical events.
