Thames Barrier
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 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. History Background Flooding in London has been a problem since Roman times. In 1954, the Waverley Committee, established to investigate the serious North Sea flood of 1953 which affected parts of the Thames Estuary and parts of London, recommended that "as an alternative to raising the banks, the possibility and cost of erecting a structure across the Thames which could be closed in a surge should be urgently investigated".

London
London is the capital and List of urban areas in the United Kingdom, largest city of England and the United Kingdom, with a population of just under 9 million. It stands on the River Thames in south-east England at the head of a estuary down to the North Sea, and has been a major settlement for two millennia. The City of London, its ancient core and financial centre, was founded by the Roman Empire, Romans as ''Londinium'' and retains its medieval boundaries.See also: Independent city#National capitals, Independent city § National capitals The City of Westminster, to the west of the City of London, has for centuries hosted the national Government of the United Kingdom, government and Parliament of the United Kingdom, parliament.

Silvertown
Silvertown is a district in the London Borough of Newham, in east London, England. It lies on the north bank of the Thames and was historically part of the parishes of West Ham and East Ham, hundred of Becontree, and the historic county of Essex. Since 1965, Silvertown has been part of the London Borough of Newham, a local government district of Greater London. It forms part of the London E16 postcode district along with Canning Town and Custom House. The area was named after the factories established by Stephen William Silver in 1852, and is now dominated by the Tate & Lyle sugar refinery and the John Knight ABP animal rendering plant. A £3.5billion redevelopment of part of the district was approved in 2015. History In 1852 S.W. Silver & Company moved to the area from Greenwich and established a rubber works, originally to make waterproof clothing. This subsequently developed into the works of the India Rubber, Gutta Percha and Telegraph Works Company, which c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greater London Council
The Greater London Council (GLC) was the top-tier local government administrative body for Greater London from 1965 to 1986. It replaced the earlier London County Council (LCC) which had covered a much smaller area. The GLC was dissolved in 1986 by the Local Government Act 1985 and its powers were devolved to the London boroughs and other entities. A new administrative body, known as the Greater London Authority (GLA), was established in 2000. Creation The GLC was established by the London Government Act 1963, which sought to create a new body covering more of London rather than just the inner part of the conurbation, additionally including and empowering newly created London boroughs within the overall administrative structure. In 1957 a Royal Commission on Local Government in Greater London had been set up under Sir Edwin Herbert, and this reported in 1960, recommending the creation of 52 new London boroughs as the basis for local government. It further recommended that the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compressed Air
Compressed air is air kept under a pressure that is greater than atmospheric pressure. Compressed air is an important medium for transfer of energy in industrial processes, and is used for power tools such as air hammers, drills, wrenches, and others, as well as to atomize paint, to operate air cylinders for automation, and can also be used to propel vehicles. Brakes applied by compressed air made large railway trains safer and more efficient to operate. Compressed air brakes are also found on large highway vehicles. Compressed air is used as a breathing gas by underwater divers. It may be carried by the diver in a high pressure diving cylinder, or supplied from the surface at lower pressure through an air line or diver's umbilical. Similar arrangements are used in breathing apparatus used by firefighters, mine rescue workers and industrial workers in hazardous atmospheres. In Europe, 10 percent of all industrial electricity consumption is to produce compressed air—am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River Bed
A stream bed or streambed is the bottom of a stream or river (bathymetry) or the physical confine of the normal water flow ( channel). The lateral confines or channel margins are known as the stream banks or river banks, during all but flood stage. Under certain conditions a river can branch from one stream bed to multiple stream beds. A flood occurs when a stream overflows its banks and flows onto its flood plain. As a general rule, the bed is the part of the channel up to the normal water line, and the banks are that part above the normal water line. However, because water flow varies, this differentiation is subject to local interpretation. Usually, the bed is kept clear of terrestrial vegetation, whereas the banks are subjected to water flow only during unusual or perhaps infrequent high water stages and therefore might support vegetation some or much of the time. The nature of any stream bed is always a function of the flow dynamics and the local geologic materials, i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crayford
Crayford is a town and electoral ward in South East London, England, within the London Borough of Bexley. It lies east of Bexleyheath and north west of Dartford. Crayford was in the historic county of Kent until 1965. The settlement developed by the river Cray, around a ford that is no longer used. History An Iron Age settlement existed in the vicinity of the present St Paulinus Church between the Julian and Claudian invasions of Britain, from roughly 30 BC to AD 40. Roman ruins have been discovered and Crayford is one of several places proposed as the site of Noviomagus, a place mentioned in the Antonine Itinerary as being on the Roman equivalent of the later Watling Street. Crayford is also plausible as the site of the bloody battle of Crecganford ("Creeks ford") in 457 in which Hengist defeated Vortimer to become the supreme sovereign of Kent. The Anglo-Saxon Chronicle written around 400 years later describes how Hengist and Æsc defeated the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sluice Gate
Sluice ( ) is a word for a channel controlled at its head by a movable gate which is called a sluice gate. A sluice gate is traditionally a wood or metal barrier sliding in grooves that are set in the sides of the waterway and can be considered as a bottom opening in a wall. Sluice gates are one of the most common hydraulic structures in controlling flow rate and water level in open channels such as rivers and canals. They also could be used to measure the flow. A water channel containing a sluice gate forms a type of lock to manage the water flow and water level. It can also be an open channel which processes material, such as a River Sluice used in gold prospecting or fossicking. A mill race, leet, flume, penstock or lade is a sluice channeling water toward a water mill. The terms sluice, sluice gate, knife gate, and slide gate are used interchangeably in the water and wastewater control industry. They are also used in wastewater treatment plants and to recover minerals in m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

David Maxwell Fyfe, 1st Earl Of Kilmuir
David Patrick Maxwell Fyfe, 1st Earl of Kilmuir, (29 May 1900 – 27 January 1967), known as Sir David Maxwell Fyfe from 1942 to 1954 and as Viscount Kilmuir from 1954 to 1962, was a British Conservative politician, lawyer and judge who combined an industrious and precocious legal career with political ambitions that took him to the offices of Solicitor General, Attorney General, Home Secretary and Lord High Chancellor of Great Britain. One of the prosecuting counsels at the Nuremberg Trials, he subsequently played a role in drafting the European Convention on Human Rights. As Home Secretary he led a crackdown against homosexuals in the UK in the 1950s, and declined to commute Derek Bentley's death sentence for the murder of a police officer. His political ambitions were ultimately dashed in Harold Macmillan's cabinet reshuffle of July 1962. Early life Born in Edinburgh, the only son of William Thomson Fyfe, Headmaster of Aberdeen Grammar School, by his second wife Isabe ...

Thames Estuary
The Thames Estuary is where the River Thames meets the waters of the North Sea, in the south-east of Great Britain. Limits An estuary can be defined according to different criteria (e.g. tidal, geographical, navigational or in terms of salinity). For this reason the limits of the Thames Estuary have been defined differently at different times and for different purposes. Western This limit of the estuary has been defined in two main ways: * The narrow estuary is strongly tidal and is known as the Tideway. It starts in south-west London at Teddington Lock and weir, Teddington/ Ham. This point is also mid-way between Richmond Lock which only keeps back a few miles of man-made head (stasis) of water during low tide and the extreme modern-era head at Thames Ditton Island on Kingston reach where slack water occurs at maximal high tide in times of rainfall-caused flooded banks. In terms of salinity the transition from freshwater to estuarine occurs around Battersea; east of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Sea Flood Of 1953
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, causing extensive flooding. The storm and flooding occurred at the end of Saturday, 31 January 1953 and morning of the next day. A combination of a high spring tide and a severe European windstorm over the North Sea caused a storm tide. The combination of wind, high tide, and low pressure caused the sea to flood land up to above mean sea level. Flooding summary In the Netherlands 20% of the land was below mean sea level (subsequently with the expansion of Flevoland this proportion has increased); the next-highest 30% sat at less than above sea level. Such land relies heavily on sea defences and was worst affected, recording 1,836 deaths and widespread damage. Most of the casualties occurred in the southern province of Zeeland. In England, 307 people were killed in the countie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roman Britain
Roman Britain was the period in classical antiquity when large parts of the island of Great Britain were under occupation by the Roman Empire. The occupation lasted from AD 43 to AD 410. During that time, the territory conquered was raised to the status of a Roman province. Julius Caesar invaded Britain in 55 and 54 BC as part of his Gallic Wars. According to Caesar, the Britons had been overrun or culturally assimilated by other Celtic tribes during the British Iron Age and had been aiding Caesar's enemies. He received tribute, installed the friendly king Mandubracius over the Trinovantes, and returned to Gaul. Planned invasions under Augustus were called off in 34, 27, and 25 BC. In 40 AD, Caligula assembled 200,000 men at the Channel on the continent, only to have them gather seashells ('' musculi'') according to Suetonius, perhaps as a symbolic gesture to proclaim Caligula's victory over the sea. Three years later, Claudius directed f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
