Tidal currents -> "Courants de marée"			Resulting from the "Tidal wave", they depend on the water depth and the site caracteristics.Their directions and intensities vary periodically under the effect of tides periodicity and Coriolis force.
Tidal river -> "Fleuve à marée"			River which is subject to tidal oscillations.
Tidal wave -> "Onde de marée"			Wave of long period (12 hours) created by the attraction pull of the Sun and the Moon. See "Gravitational pull", "Wave generation".
Tide gauge -> "Marégraphe"
Tide periodicity -> "Périodicité des marées"			Tides repeat themselves exactly with a period of approximately 19 years.
Trough elevation -> "Elévation de creux"	t	m	Absolute value of the trough depth referred to "Still water level".
Trough period -> "Période creux"	Tt	s	Duration between two successive wave trough.
Tsunamis -> "Tsunamis"			See "Seismic disturbances", "Wave generation", "Solitary wave".
