The River Thames, known alternatively in parts as the River Isis, is a river that flows through southern England including London. At 346 kilometres (215 mi), it is the longest river entirely in England and the second-longest in the United Kingdom, after the River Severn.
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. Built about 2 miles east of the Isle of Dogs, its northern bank is in Silvertown in the London Borough of Newham and its southern bank is in the New Charlton area of the Royal Borough of Greenwich.
Storm tides of the North Sea are coastal floods associated with extratropical cyclones crossing over the North Sea, the severity of which is affected by the shallowness of the sea and the orientation of the shoreline relative to the storm's path, as well as the timing of tides. The water level can rise to more than 5 metres (17 ft) above the normal tide as a result of storm tides.
The Maeslantkering is a storm surge barrier on the Nieuwe Waterweg, in South Holland, Netherlands. It was constructed from 1991 to 1997. As part of the Delta Works the barrier responds to water level predictions calculated by a centralized computer system called BOS. It automatically closes when Rotterdam is threatened by floods.
A storm surge, storm flood, tidal surge, or storm tide is a coastal flood or tsunami-like phenomenon of rising water commonly associated with low-pressure weather systems, such as cyclones. It is measured as the rise in water level above the normal tidal level, and does not include waves.
The Thames Estuary is where the River Thames meets the waters of the North Sea, in the south-east of Great Britain.
The 1953 North Sea flood was a major flood caused by a heavy storm surge that struck the Netherlands, north-west Belgium, England and Scotland. Most sea defences facing the surge were overwhelmed, resulting in extensive flooding.
A flood barrier, surge barrier or storm surge barrier is a specific type of floodgate, designed to prevent a storm surge or spring tide from flooding the protected area behind the barrier. A surge barrier is almost always part of a larger flood protection system consisting of floodwalls, levees, and other constructions and natural geographical features. Flood barrier may also refer to barriers placed around or at individual buildings to keep floodwaters from entering the buildings.
The Tideway is the part of the River Thames in England which is subject to tides. This stretch of water is downstream from Teddington Lock. The Tideway comprises the upper Thames Estuary including the Pool of London.
The 1928 Thames flood was a disastrous flood of the River Thames that affected much of riverside London on 7 January 1928, as well as places further downriver. Fourteen people died and thousands were made homeless when floodwaters poured over the top of the Thames Embankment and part of the Chelsea Embankment collapsed. It was the last major flood to affect central London, and, along with the disastrous North Sea flood of 1953, helped lead to the implementation of new flood control measures that culminated in the construction of the Thames Barrier in the 1970s.
Flood is a 2002 disaster thriller novel by Richard Doyle. Set in present-day London, the novel depicts a disastrous flood and fire of London, caused by a storm, and the consequential accident at an oil refinery, and failure of the Thames Barrier. The plot is similar to his 1976 novel Deluge, updated to include the construction of the Thames Flood Barrier.
Flood control methods are used to reduce or prevent the detrimental effects of flood waters. Flooding can be caused by a mix of both natural processes, such as extreme weather upstream, and human changes to waterbodies and runoff. Flood control methods can be either of the structural type and of the non-structural type. Structural methods hold back floodwaters physically, while non-structural methods do not. Building hard infrastructure to prevent flooding, such as flood walls, is effective at managing flooding. However, best practice within landscape engineering is more and more to rely on soft infrastructure and natural systems, such as marshes and flood plains, for handling the increase in water.
Juliette Mole is an English actress and artist, now based in London. She is married to the actor Lloyd Owen.
Coastal flooding occurs when dry and low-lying land is submerged (flooded) by seawater. The range of a coastal flooding is a result of the elevation of floodwater that penetrates the inland which is controlled by the topography of the coastal land exposed to flooding. The seawater can flood the land via several different paths: direct flooding, overtopping or breaching of a barrier. Coastal flooding is largely a natural event. Due to the effects of climate change and an increase in the population living in coastal areas, the damage caused by coastal flood events has intensified and more people are being affected.
Cyclone Xaver, also known as the North Sea flood or tidal surge of 2013, was a winter storm that affected northern Europe. Force 12 winds and heavy snowfall were predicted along the storm's path, and there were warnings of a significant risk of storm surge leading to coastal flooding along the coasts of the North and Irish Seas.
The 2013–2014 United Kingdom winter floods saw areas of the United Kingdom inundated following severe storms. The south of England saw heavy rainfalls associated with these storms which caused widespread flooding, power cuts and major disruptions to transport. Economically, the worst affected areas were Somerset, Devon, Dorset and Cornwall in the south west and the Thames Valley in the south east.
The New York Harbor Storm-Surge Barrier is a proposed flood barrier system to protect the New York-New Jersey Harbor Estuary from storm surges. The proposed system would consist of one barrier located across the mouth of Lower New York Bay, possibly between Sandy Hook (N.J.) and Rockaway (N.Y.), and a second on the upper East River to provide a ring of protection to most of the bi-state region. Through extensive use of floodgates, both barriers would have largely open cross-sections during normal conditions to minimize environmental impacts on the estuary and port operations.
The River Hull tidal surge barrier is a flood control gate located on the River Hull in the city of Kingston upon Hull, in the East Riding of Yorkshire, England. The barrier impounds the river in times of tidal surges, preventing water moving upstream of the river from the Humber Estuary, and flooding the areas of the city which are near to the river, or susceptible to flooding. It is held horizontal when not in use, and turns 90 degrees before being lowered to the riverbed in the event of a tidal surge. It is the second largest flood barrier in the United Kingdom after the Thames Barrier in London.
Lagoon Hull is a proposed £1.5 billion development on the Humber Estuary foreshore between Hessle and Kingston upon Hull, in the East Riding of Yorkshire, England. The proposed lagoon would be formed from a stone causeway and will provide an outer lock gate in the Humber Estuary which would effectively dam the River Hull, making it a non-tidal waterway. The 11-kilometre (6.8 mi) long causeway would also provide a dual carriageway from the A63 at Hessle which would run to Hull Docks, taking traffic away from the city centre. The scheme is being vaunted as one that will prevent future flooding in Hull when sea levels rise, and contribute to less flooding in the wider Humber Estuary.
The Embanking of the tidal Thames is the historical process by which the lower River Thames, at one time a broad, shallow waterway winding through malarious marshlands, has been transformed by human intervention into a deep, narrow tidal canal flowing between solid artificial walls, and restrained by these at high tide. The Victorian civil engineering works in central London, usually called "the Embankment", are just a small part of the process.
