These computations are obtained using the harmonic constants method. In this method, sea surface elevation in one particular point is computed as the sum of a series of periodic functions, of which the period, amplitude and phase are deducted from the analysis of long term in situ observations at this particular point. Meteorological effects and the potential impact of global warming on the sea level are to be taken into account.
