An artificial barrier, usually constructed across an estuary, designed to maintain different water levels on either side.

Ebb tide

The stage of a tide in which the water depth is reducing.

Flood tide

The stage of a tide in which the water depth is increasing.

Neap tide

Smaller fortnightly tides falling between the spring tides.

Spring tide

Large fortnightly tides, resulting from the Earth, Sun, and Moon being approximately in line

Tidal basin

The area of water behind a tidal barrage.

Tidal currents

Water currents resulting from tidal action.

Tidal stream

A tidal current which has been accelerated as a result of the natural geography.


The response of the world’s seas and oceans to the influences of the Moon and the Sun relative to the Earth.
