Tide table. 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 ...
Tide. Simplified schematic of only the lunar portion of Earth's tides, showing (exaggerated) high tides at the sublunar point and its antipode for the hypothetical case of an ocean of constant depth without land, and on the assumption that Earth is not rotating; otherwise there is a lag angle. Solar tides not shown.
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.
The Thames Barrier is a retractable barrier system built to protect the floodplain of most of Greater London from exceptionally high tides and storm surges moving up from the North Sea. It has been operational since 1982. When needed, it is closed (raised) during high tide; at low tide, it can be opened to restore the river's flow towards the sea.
High tide reaches Putney about 30 minutes later. Low-lying banks of London are naturally vulnerable to flooding by storm surges . The threat has increased due to a slow but continuous rise in high water level, caused by the extremely slow 'tilting' of Britain (up in the north and down in the south) due to post-glacial rebound and the gradual ...
Republic of Ireland, United Kingdom, France, Channel Islands, Isle of Man, Spain, Portugal. Cyclone Anne was a European windstorm which caused €75 million in damage across western Europe in early January 2014, [1] followed days later by Cyclone Christina .
The North Sea flood of 1953 was the worst flood of the 20th century in England and Scotland. Over 1,600 km (990 mi) of coastline was damaged, [22] and sea walls were breached in 1,200 places, [23] inundating 160,000 acres (65,000 ha; 250 sq mi). [22] Flooding forced over 30,000 people from their homes, [22] [23] and 24,000 properties were ...
The Severn bore is a tidal bore seen on the tidal reaches of the River Severn in south western England. It is formed when the rising tide moves into the funnel-shaped Bristol Channel and Severn Estuary and the surging water forces its way upstream in a series of waves, as far as Gloucester and beyond. The bore behaves differently in different ...
