River Pinn
The Pinn is a suburban, outer west London river. It has dendritic headwaters, the furthest is considered its sourcein Harrow Weald. Its confluence with Frays River makes it a tributary of the Colne. It is one of three principal rivers wholly in the historic county of Middlesex. Route The river runs through Pinner, the northern halves of Eastcote and Ruislip: the latter may be a notable rise-lip of land as 17th century maps often have the place name but likely derives from "rush leap" from the local width of the river. It then runs through Ickenham and on to Uxbridge, where it passes through the former grounds of RAF Uxbridge and Brunel University. The Pinn continues on to Pield Heath and Cowley, passing under the Grand Union canal before joining the Frays River, an anabranch of the Colne, at Yiewsley. ''A ...

River Colne, Hertfordshire
The Colne is a river and a tributary of the River Thames in England. Just over half its course is in south Hertfordshire. Downstream, it forms the boundary between Buckinghamshire and the London Borough of Hillingdon. The confluence with the River Thames is on the Staines reach (above Penton Hook Lock) at Staines-upon-Thames. Two of its distributaries, constructed in the 1600 – 1750 period largely for aesthetic reasons for Hampton Court and for Syon Park, have been maintained. Their main purpose was not drinking water but these can be likened to the New River in scale and in date. Crossing its route, many viaducts and a canal, the intersecting Grand Union Canal, have been recognised for pioneering engineering during the Industrial Revolution. Digging for gravel and clay along its lower course near Rickmansworth has created a belt of flooded pits below the water table, as established lakes, many of which are well-adapted habitats for wildlife, protected as nature rese ...

RAF Uxbridge
RAF Uxbridge was a Royal Air Force (RAF) station in Uxbridge, within the London Borough of Hillingdon, occupying a site that originally belonged to the Hillingdon House estate. The British Government purchased the estate in 1915, three years before the founding of the RAF. Until the outbreak of the Second World War in 1939, the station was open to the public. The station is best known as the headquarters of No. 11 Group RAF, which was responsible for the aerial defence of London and the south-east of England during the Battle of Britain. Hillingdon House served as the group's headquarters. A bunker, subsequently known as the Battle of Britain Bunker, was built nearby to house the Operations Room, which controlled fighter squadrons operating within the group. The Operations Room was also responsible for providing air support during the evacuation of Dunkirk in May 1940 ( Operation Dynamo) and the D-Day landings (Operation Overlord). It was here that Winston Churchill fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tideway
The Tideway is a 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. Tidal activity Depending on the time of year, the river tide rises and falls twice a day by up to 7 m (24 ft). Because the tide goes against the outflow of fresh water from the Thames Basin, it takes longer to subside (6–9 hours) than it does to flow in (4–5 hours). London Bridge is used as the basis for published tide tables giving the times of high tide. 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 rise in sea levels due to climate change.

Mogden Sewage Treatment Works
Mogden Sewage Treatment Works is a sewage treatment plant in the Ivybridge section of Isleworth, West London, formerly known as Mogden. Built in 1931–36 by Middlesex County Council and now operated by Thames Water, it is the third largest sewage works in the United Kingdom. It treats the waste water from about 1.9 million people served by three sewers in North and West London. The plant has been extended to its geographical boundaries and is constantly being upgraded with new process, most recently in OfWat Amp6 by the Costain Atkins Joint venture who delivered 6MW of Combined Heat and Power (CHP) generation, New process air blowers for Batterys A&B and 6 new gravity sludge thickening streams. The site now covers . History The plant was built in 1931–36 for £1.7 million by Middlesex County Council, replacing 28 small sewage treatment facilities as part of the West Middlesex (Mogden-Perry Oaks) Main Drainage Scheme.Philip Howard, ''London's River'', London: Hamilton, ...

Paddington Arm
The Paddington Canal or Paddington Arm of the Grand Union Canal is a canal to Paddington in central London, England. It runs from the west of the capital at Bull's Bridge in Hayes. Little Venice — its only junction — is with the Regent's Canal, London that runs to Limehouse Basin to the east. The arm and the two canals it links are fed by water by the Brent Reservoir. The Paddington Arm is part of a long pound that stretches for nearly thirty miles. History Transport and the economy The canal was authorised by an Act of April 1795 later called the Grand Junction Canal Act (of which there were three that year). At the time the Industrial Revolution was advanced. Promoters saw a purpose in opening a water-transport route between two divergent economies. London had many niche industries and global imports added to which from the late 1830s was added almost direct access to the western rail terminus. The Midlands had mass-manufactured goods, raw and processed com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grand Union Canal
The Grand Union Canal in England is part of the British canal system. It is the principal navigable waterway between London and the Midlands. Starting in London, one arm runs to Leicester and another ends in Birmingham, with the latter stretching for with 166 locks from London. The Birmingham line has a number of short branches to places including Slough, Aylesbury, Wendover, and Northampton. The Leicester line has two short arms of its own, to Market Harborough and Welford. It has links with other canals and navigable waterways, including the River Thames, the Regent's Canal, the River Nene and River Soar, the Oxford Canal, the Stratford-upon-Avon Canal, the Digbeth Branch Canal and the Birmingham and Fazeley Canal. The canal south of Braunston to the River Thames at Brentford in London is the original Grand Junction Canal. At Braunston the latter met the Oxford Canal linking back to the Thames to the south and to Coventry to the north via the Coventry Canal. "Grand ...

Slough Arm
The Slough Arm is a short canal branch from the Grand Union Main Line to Slough in Berkshire (before 1974 in Buckinghamshire), England. It was originally opened to serve the brick-making industry. The last commercial traffic was carried in 1960, but as the plans to fill it in were opposed locally, the stretch was re-opened in 1975 and has remained in use since. History With the demand for bricks for the buildings of London continuing to increase, a canal branch to Slough was first proposed in 1878 by Hubert Thomas. It would run from Bulls Bridge on the Grand Union Canal (then the Grand Junction Canal) to Slough, where new brickworks would be opened. Thomas completed a survey in 1879, and the route was altered slightly, with the junction moving to Cowley Peachey. An Act of Parliament was sought, which was opposed by the Great Western Railway, but despite this, the Act was passed in July 1879, although the Slough end was truncated back to Stoke Road, as the original termi ...

Parallel Drainage
In geomorphology, drainage systems, also known as river systems, are the patterns formed by the streams, rivers, and lakes in a particular drainage basin. They are governed by the topography of land, whether a particular region is dominated by hard or soft rocks, and the gradient of the land. Geomorphologists and hydrologists often view streams as part of drainage basins (and sub-basins). This is the topographic region from which a stream receives runoff, throughflow, and its saturated equivalent, groundwater flow. The number, size, and shape of the drainage basins varies and the larger and more detailed the topographic map, the more information is available. Drainage patterns Per the lie of channels, drainage systems can fall into one of several categories, known as drainage patterns. These depend on the topography and geology of the land. All forms of transitions can occur between parallel, dendritic, and trellis patterns. Accordant versus discordant drainage patterns A drai ...

Second World War
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yiewsley
Yiewsley ( ) is a large suburban village in the London Borough of Hillingdon, England, 2 miles (3 km) south of Uxbridge, the borough's commercial and administrative centre. Yiewsley was a chapelry in the ancient parish of Hillingdon, Middlesex. The population of the ward was 12,979 at the 2011 Census. Toponymy Yiewsley is not recorded in the Domesday Book of 1086. The place-name is believed to be derived from the Anglo-Saxon ''Wifeleslēah'': "Wifel's woodland clearing". The earliest written record of Yiewsley is from 1235 where it is shown as ''Wiuesleg'' in Assize Rolls. Geography The western side of Yiewsley lies within the Colne Valley Regional Park. Here the River Colne forms the county boundary between the London Borough of Hillingdon and Buckinghamshire. The confluence of the Frays River and River Pinn also occurs in this area and there are several man-made lakes.

Anabranch
An anabranch is a section of a river or stream that diverts from the main channel or stem of the watercourse and rejoins the main stem downstream. Local anabranches can be the result of small islands in the watercourse. In larger anabranches, the flow can diverge for a distance of several kilometers before rejoining the main channel. Word usage and related terms The term ''anabranch'', in its hydrological meaning, is used more frequently in Australia than in the rest of the English-speaking world. The term ''anabranching river'' describes a river with many anabranches, whilst an anastomosing river is an organic-rich subset of this river type. The term braided river describes watercourses which are divided by small islands into multiple channel threads within a single main channel, but the term does not describe the multiple channels of an anabranching river. A distributary is a branch of a river that does not rejoin the main channel; these are common on and near river d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
