Tidal range is the difference in height between high tide and low tide. Tides are the rise and fall of sea levels caused by gravitational forces exerted by the Moon and Sun , by Earth's rotation and by centrifugal force caused by Earth's progression around the Earth-Moon barycenter .

Tidal prediction summing constituent parts. The tidal coefficients are defined on the page theory of tides. Remember that astronomical tides do not include weather effects. Also, changes to local conditions (sandbank movement, dredging harbour mouths, etc.) away from those prevailing at the measurement time affect the tide's actual timing and ...
On the contrary, when the wind and the stream flow in the same direction, the sea becomes calm, provided that the tidal coefficient is not too great. The uneven seabed – both Alderney and La Hague lie in the Armorican Massif – makes the situation more complicated. Bad weather can produce abundant wind-blown foam, making visibility poor.
Tide tables, sometimes called tide charts, are used for tidal prediction and show the daily times and levels of high and low tides, usually for a particular location. [1] Tide heights at intermediate times (between high and low water) can be approximated by using the rule of twelfths or more accurately calculated by using a published tidal ...
Where these lines intersect the tidal elevation is zero during a full tidal period and thus this is the location of the Amphidromic points. In the real world, the reflected Kelvin wave has a lower amplitude due to energy loss as a result of friction and through the transfer via Poincare waves (lower left panel of animation 1).
High and low tide in the Bay of Fundy. The theory of tides is the application of continuum mechanics to interpret and predict the tidal deformations of planetary and satellite bodies and their atmospheres and oceans (especially Earth's oceans) under the gravitational loading of another astronomical body or bodies (especially the Moon and Sun).
Tidal waves are not perfectly reflected, resulting in energy loss which causes a smaller reflected wave compared to the incoming wave. [8] Consequently, on the northern hemisphere, the amphidromic point will be displaced from the centre line of the channel towards the left of the direction of the incident wave.
