The field of action of a tide wave.

The higher the compensation speed of the differences generated by the action of the Moon and Sun, in the water density, pressure, and levels, the larger the tide basin, and the range of the tide wave.

Generation of the tide.

The first phase of each cycle is the generation of the tide (decreasing of water density), with the ensuing increasing of both the water pressure, and the water levels.

The space and the time of a tidal basin.

A tidal basin has its own space, and its own time, the tidal cycle, which may be either diurnal, or semi-diurnal.

During that time, the equilibria (water pressure and water levels) tend to get restored until the onset of the successive tide cycle, when fresh imbalances change the course of the ongoing compensations.

At that point, les jeux sont faits; rien ne va plus ... the tidal basin cannot be larger than the area, where the compensations are carried out, within one tidal cycle.

The longer the duration of the tide cycle, and the higher the speed the equilibria tend to be restored, the larger will be the extension of the basin considered.

Range of a tide wave.

In other terms, the range of a tide wave is where a restoration of balances takes place after the tide generation. Indeed an endless restoration of balances. It would be determined, directly, by the rates the inequalities are compensated, and, by the duration of the tide cycle (diurnal, semi-diurnal).

By and large, <the speed at which the equilibria tend to be restored> x <the duration of the tide cycle> gives the extension of the basin considered.

The space delimitation of a tide basin.

So, the space delimitation of a tide basin, is the space within which the compensations may take place, before the onset of the next tide cycle.

Given the same duration of the tide cycle - semi-diurnal, diurnal - the higher the compensation rates, the larger the basin.

Stable response of a tide basin.

Relative to the astronomical situations, the time response of a tide basin keeps constant, as long as its depth and conformation keep constant, made however abstraction of other variables, such as the weather conditions.
