2. Constraints on the selection of potential tidal sites
2.1 Hydraulic and geographical constraints
Sites where the tidal range is large enough to justify the use of tidal energy are rather rare. For the construction of a tidal installation to be economically viable, the site must offer amplitudes of at least 5 m, comprise a natural basin (gulfs, bays, estuaries, etc.) capable of retaining a significant quantity of water at high tide, or generate significant currents usable by tidal turbines.
To choose a tidal site, a large tidal range is not a sufficient criterion. Large tidal ranges are often associated with weak tidal currents, when they occur at the bottom of gulfs. The available tidal energy of a sea basin is the natural energy of the site, whose order of magnitude is...
