tidal island - The tides can vary greatly, at roughly 14 metres (46 ft) between high and low water marks (wiki)
See en.wikipedia.org

The landscape is dynamic, constantly moulded and altered by tidal action (UNEP-WCMC)

the world’s largest intertidal mudflat + ... Due to the tidal asymmetry (fast flood tides and slow ebb tides), the sediments transported by tides can be accumulated in the intertidal zone (nom file)

"Tidal waves are a regular phenomenon and may be up to 75m high. The land is constantly being changed, moulded and shaped by the action of the tides." (AB ev)

Complex tide-dominated barrier coast (not deltaic). (AB)

The Isla de los Pajaros is an 18 ha island 800m off the southeast coast of Golfo San José connected to the mainland at low tide (UNEP-WCMC)

Fundy Bay with the highest tides in the world. The beach cannot be visited during high tides.

tidal mixing associated to tides that can reach over 10m high (AB ev)

diverse tidal flat ecosystems. Whilst all component parts are representative of archipelagic tidal flats in the Yellow Sea, each component part represents one of four tidal flat subtypes of Getbol: the estuarine type, open embayed type, archipelago type and semi-enclosed type. (AB ev)

Garonne's tidal bore (un mascaret)

it has the greatest tidal range in the region (AB ev)

part of the inscription zone include Qiantang River bank where the Qiantang Tidal Bore which is the world largest occured

tidal swamps (Coastal WHS)

high degree of oxygenation resulting from the strong tidal currents (Coastal WHS)

the shrine is designed by use the tidal effect to make the place look floating

marked by one of the most extreme tidal ranges in the world, averaging at 11.6 metres (Unesco)

a tidal lagoon known as The Fleet, one of the most important saline lagoons in Europe (Coastal WHS)

"AdRBR offers spectacular scenes associated with the tide regime. At high tide only two sandy islands and some isolated rock formations in the surrounding reef stand above water. The scene changes dramatically at low tide when the reef ring of the Atoll – a natural 1.5m wall bordered by several sandbanks – is exposed and several shallow lagoons and tidal pools are formed producing a spectacular and colourful landscape. In addition, large numbers of fish get trapped in tidal pools, transforming the atoll into a natural aquarium of great beauty" (AB ev)

Aldabra has very large tides for a coral atoll (cf others in Pacific and Indian Oceans). This shapes the ecology e.g the undercut "Champigon" pillars. See
