energy period, <of a water wave>
characteristic wave period associated with energy propagation expressed as the group velocity weighted mean period of the hauteur de vague

Note 1 to entry: It is numerically equivalent to the period of a monochromatic wave in deep water with wave elevation variance and energy flux equal to a polychromatic sea state.

Note 2 to entry: In accordance with International Association for Hydraulic Research (International Association for Hydraulic Research (IAHR), working group on wave generation and analysis, 1989, List of sea state parameters, Journal of Waterway, Port, Coastal and Ocean Engineering 115 (6), 793–808) the spectral estimate of the energy period is preferred.

période d’énergie, <d’une vague> f
période des vagues caractéristique associée à la propagation de l’énergie exprimée comme la période moyenne pondérée par la vitesse de groupe du spectre des vagues

Note 1 à l’article: La période d’énergie est numériquement équivalente à la période d’une vague monochromatique en eau profonde, avec équivalence de la variance d’élévation des vagues et du flux d’énergie à un état de mer polychromatique.

Note 2 à l’article: Conformément à l’Association Internationale de Recherches Hydrauliques (International Association for Hydraulic Research (IAHR), working group on wave generation and analysis, 1989, List of sea state parameters, Journal of Waterway, Port, Coastal and Ocean Engineering 115 (6), 793–808), l’estimation spectrale de la période d’énergie est préférable.
