Geography Of London
London is the largest urban area and capital city of the United Kingdom. It is located in the southeast of Great Britain. The London region covers an area of , and had a population of 7,172,036 in 2001 and a population density of 4,542 people per square kilometre. A larger area, referred to as the London Metropolitan Region or the London Metropolitan Agglomeration covers an area of , and had a population of 12,653,500 and a population density of 1,510 people per square kilometre. London is a port on the Thames (see main article ''Port of London''), a navigable river. The river has had a major influence on the development of the city. London began on the Thames' north bank and for a long time the main focus of the city remained on the north side of the Thames. For many centuries London Bridge was the only bridge in or close to the city. When more bridges were built in the 18th century, the city expanded in all directions as the mostly flat or gently rolling countryside presen ...

North Downs
The North Downs are a ridge of chalk hills in south east England that stretch from Farnham in Surrey to the White Cliffs of Dover in Kent. Much of the North Downs comprises two Areas of Outstanding Natural Beauty (AONBs): the Surrey Hills and the Kent Downs. The North Downs Way National Trail runs along the North Downs from Farnham to Dover. The highest point in the North Downs is Botley Hill, Surrey ( above sea level). The ''County Top'' of Kent is Betsom's Hill ( above sea level), which is less than 1 km from Westerham Heights, Bromley, the highest point in Greater London at an elevation of . Etymology 'Downs' is from Old English ''dun'', meaning, amongst other things, "hill". The word acquired the sense of "elevated rolling grassland" around the 14th century. The name contains "North" to distinguish them from a similar range of hills – the South Downs – which runs roughly parallel to them but some to the south.

River Roding
The River Roding () rises at Molehill Green, Essex, England, then flows south through Essex and London and forms Barking Creek as it reaches the River Thames. Course The river leaves Molehill Green and passes through or near a group of eight or nine villages in Essex known collectively as the Rodings, as their names are 'Roding' prefixed with various different specific names (High, Margaret, Aythorpe etc.). After Chipping Ongar, the river flows under the M25 motorway by Passingford Bridge and Abridge. The river then runs between Loughton and Chigwell, where the Roding Valley Meadows make up the largest surviving area of traditionally managed river-valley habitat in Essex. This nature reserve consists of unimproved wet and dry hay meadows, rich with flora and fauna and bounded by thick hedgerows, scrubland, secondary woodland and tree plantation. The meadows stretch down to the M11 motorway and the Roding Valley tube station is situated close to the area, although Loughton ...

Bow Creek (England)
Bow Creek is a long tidal estuary of the English River Lea and is part of the Bow Back Rivers. Below Bow Locks the creek forms the boundary between the London Boroughs of Newham and Tower Hamlets, in East London. History The River Lea rises in the town of Luton in Bedfordshire, and flows to the east and then the south to reach the River Thames at Leamouth. The final are known as Bow Creek, and follow a meandering route across a low-lying area formerly called Bromley Marsh, but now occupied by gas works and trading estates. The river is one of the oldest navigations in the country, but the creek is tidal, providing insufficient depth for navigation at low tide. Use of the river for navigation is recorded in documents dating from 1190 and, in 1424, it became the first river in Britain where improvements were authorised by an Act of Parliament. Another act of 1571 allowed the Lord Mayor to make cuts and improvements to the river and to construct towing paths on both sides of i ...

River Lea
The River Lea ( ) is in South East England. It originates in Bedfordshire, in the Chiltern Hills, and flows southeast through Hertfordshire, along the Essex border and into Greater London, to meet the River Thames at Bow Creek. It is one of the largest rivers in London and the easternmost major tributary of the Thames. The river's significance as a major east–west barrier and boundary has tended to obscure its importance as north–south trade route. Below Hertford the river has since medieval times had alterations made to make it more navigable for boats between the Thames and eastern Hertfordshire and Essex, known as the Lee Navigation. This stimulated much industry along its banks. The navigable River Stort, the main tributary, joins it at Hoddesdon. While the lower Lea remains somewhat polluted, its upper stretch and tributaries, classified as chalk streams, are a major source of drinking water for London. An artificial waterway known as the New River, opened in 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River Brent
The River Brent is a river in west and northwest London, England, and a tributary of the River Thames. in length, it rises in the Borough of Barnet and flows in a generally south-west direction before joining the Tideway stretch of the Thames at Brentford. Hydronymy and etymology A letter from the Bishop of London in 705 suggesting a meeting at Breġuntford, now Brentford, is the earliest record of this place and probably therefore that of the river, suggesting that the name may be related to the Celtic *''brigant-'' meaning "high" or "elevated" perhaps linked to the goddess BrigantiaCanham, Roy; Glanville G H (1978). ''A London Museum Archaeological Report: 2000 years of Brentford''. Ch 2; pg 3. Her Majesty's Stationery Office.

River Crane, London
The River Crane, a tributary of the River Thames, runs 8.5 miles (13.6 km) in West London, England. It forms the lower course of Yeading Brook. It adjoins or passes through three London boroughs: Hillingdon, Hounslow and Richmond upon Thames, in the historic county of Middlesex. The drainage basin is heavily urbanised but many of the Hayes to Whitton flood-meadows have been conserved, forming a narrow, green vale, opening out to what remains of Hounslow Heath in the centrea near-continuous belt of semi-natural habitat. At the start of the twentieth century several small sewage works discharged to the river. However these have been consolidated with others into one (Mogden Sewage Treatment Works) which discharges directly to the upper estuary of the Thames (the Tideway). The Crane's form has been greatly altered by river engineering works: over centuries the watercourse has been subject to widening, narrowing, straightening, dredging and bank reinforcement. The greatest of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 reser ...

Subterranean Rivers Of London
The subterranean or underground rivers of London are or were the direct or indirect tributaries of the upper estuary of the Thames (the Tideway), that were built over during the growth of the metropolis of London. They now flow through culverts, with some of them now integral parts of London's sewerage system and diverted accordingly.

Woolwich
Woolwich () is a district in southeast London, England, within the Royal Borough of Greenwich. The district's location on the River Thames led to its status as an important naval, military and industrial area; a role that was maintained throughout the 16th to 20th centuries. After several decades of economic hardship and social deprivation, the area now has several large-scale urban renewal projects. Geography Woolwich is situated from Charing Cross. It has a long frontage to the south bank of the Thames river. From the riverside it rises up quickly along the northern slopes of Shooter's Hill towards the common, at and the ancient London–Dover Road, at . The ancient parish of Woolwich, more or less the present-day wards Woolwich Riverside and Woolwich Common, comprises . This included North Woolwich, which is now part of the London Borough of Newham. The ancient parishes of Plumstead and Eltham became part of the civil parish of Woolwich in 1930. Parts of the war ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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".

Post-glacial Rebound
Post-glacial rebound (also called isostatic rebound or crustal rebound) is the rise of land masses after the removal of the huge weight of ice sheets during the last glacial period, which had caused isostatic depression. Post-glacial rebound and isostatic depression are phases of glacial isostasy (glacial isostatic adjustment, glacioisostasy), the deformation of the Earth's crust in response to changes in ice mass distribution. The direct raising effects of post-glacial rebound are readily apparent in parts of Northern Eurasia, Northern America, Patagonia, and Antarctica. However, through the processes of ''ocean siphoning'' and ''continental levering'', the effects of post-glacial rebound on sea level are felt globally far from the locations of current and former ice sheets.Milne, G.A., and J.X. Mitrovica (2008) ''Searching for eustasy in deglacial sea-level histories.'' Quaternary Science Reviews. 27:2292–2302. Overview During the last glacial period, much of northern E ...
