0 in a way that relates to the tide (= the rise and fall of the sea): --
The waterway begins to widen and become tidally influenced.
tidally generated electricity
The river is now tidally influenced to the island.
Tidal forces also cause a body's rotation to gradually become tidally locked, such that it always presents the same face to its companion.
Tidally associated flows of about 30 cm/s (1 km/h) up and down the deeper parts of the canyon have been recorded.
Over the timescale of the system, it should have been tidally damped into a more circular orbit.
Although tidally locked, it is thought possible that at its terminator liquid water may well exist.
A tidally locked body takes just as long to rotate around its own axis as it does to revolve around its partner.
The eccentricity of its orbit means that it avoids becoming tidally locked.
It would circumvent the tidal lock problem by becoming tidally locked to its planet.
