Real tide data were used to extract the harmonic components
and propose a tide model (Fig. 2). Table 1 shows the amplitudes,
periods and phases of the five harmonics detected. Spectral analysis
confirmed the presence of coincident peaks in both the real and
model data (Fig. 3, where peaks in the areas “A” and “B” are the
main harmonics) and were also consistent with the tide analysis in
