An amphidromic point, also called a tidal node, is a geographical location where there is little or no difference in sea height between high tide and low tide; it has zero tidal amplitude for one harmonic constituent of the tide. [2] The tidal range (the peak-to-peak amplitude, or the height difference between high tide and low tide) for that ...
Tidal range. 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 range depends on time and location.
A storm surge, or tidal surge, which can cause waves that breach flood defences. A tsunami, a series of water waves in a body of water caused by the displacement of a large volume of water, although this usage of "tidal wave" is a misnomer and is disfavored by the scientific community. A megatsunami, which is an informal term to describe a ...
Tidal bore. A tidal bore, [ 1] often simply given as bore in context, is a tidal phenomenon in which the leading edge of the incoming tide forms a wave (or waves) of water that travels up a river or narrow bay, reversing the direction of the river or bay's current. It is a strong tide that pushes up the river, against the current.
The tidal force or tide-generating force is a gravitational effect that stretches a body along the line towards and away from the center of mass of another body due to spatial variations in strength in gravitational field from the other body. It is responsible for the tides and related phenomena, including solid-earth tides, tidal locking ...
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 ).
The Rance Tidal Power Station. This article lists most power stations that run on tidal power; both tidal range (impoundment via a barrage) and tidal stream (harnessing currents). Since tidal stream generators are an immature technology, no technology has yet emerged as the clear standard.
The wave travels upstream against the river current at a speed of 13 to 21 km/h (8 to 13 mph). [5] In the lower, broader part of the estuary near Avonmouth, the tidal surge advances as a slight roll in the deepwater channels and the water rapidly spreads across the sands and mudbanks. Often, the Severn Bore floods the lower village of Pill if ...
