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 ...

England
England is a country that is part of the United Kingdom. It shares land borders with Wales to its west and Scotland to its north. The Irish Sea lies northwest and the Celtic Sea to the southwest. It is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, and includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight. The area now called England was first inhabited by modern humans during the Upper Paleolithic period, but takes its name from the Angles, a Germanic tribe deriving its name from the Anglia peninsula, who settled during the 5th and 6th centuries. England became a unified state in the 10th century and has had a significant cultural and legal impact on the wider world since the Age of Discovery, which began during the 15th century.

Hampton Court Palace
Hampton Court Palace is a Grade I listed royal palace in the London Borough of Richmond upon Thames, southwest and upstream of central London on the River Thames. The building of the palace began in 1514 for Cardinal Thomas Wolsey, the chief minister of Henry VIII. In 1529, as Wolsey fell from favour, the cardinal gave the palace to the king to check his disgrace. The palace went on to become one of Henry's most favoured residences; soon after acquiring the property, he arranged for it to be enlarged so that it might more easily accommodate his sizeable retinue of courtiers. Along with St James' Palace, it is one of only two surviving palaces out of the many the king owned. The palace is currently in the possession of King Charles III and the Crown. In the following century, King William III's massive rebuilding and expansion work, which was intended to rival the Palace of Versailles, destroyed much of the Tudor palace.Dynes, p. 90. His work ceased in 1694, leaving the pa ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Penton Hook Lock
Penton Hook Lock is the sixth lowest lock of forty four on the non-tidal reaches of the River Thames in England. It faces an island which was until its construction a pronounced meander (a hook) and is on the site of its seasonal cutoff. It is against the left bank marking the church parish medieval border of Laleham and Staines upon Thames in Surrey for many centuries. Until 1965 their county was Middlesex. At it is the third longest lock on the river. A bend 1000 yards (900 metres) upstream of the lock, Silvery Sands, hosts Staines Regatta in the sport of rowing annually. On the opposite bank in Thorpe is Penton Hook Marina which occupies lakes once land used for gravel extraction. History Problems were long caused in erosion and to navigation by floodwaters topping the neck of the meander (a seasonal meander cutoff). The Corporation promoted the funding of the lock with formalised weirs in 1809, and Parliament passed its enabling act 1814.'Staines: Introducti ...

Confluence
In geography, a confluence (also: ''conflux'') occurs where two or more flowing bodies of water join to form a single channel. A confluence can occur in several configurations: at the point where a tributary joins a larger river (main stem); or where two streams meet to become the source of a river of a new name (such as the confluence of the Monongahela and Allegheny rivers at Pittsburgh, forming the Ohio); or where two separated channels of a river (forming a river island) rejoin at the downstream end. Scientific study of confluences Confluences are studied in a variety of sciences. Hydrology studies the characteristic flow patterns of confluences and how they give rise to patterns of erosion, bars, and scour pools. The water flows and their consequences are often studied with mathematical models. Confluences are relevant to the distribution of living organisms (i.e., ecology) as well; "the general pattern ownstream of confluencesof increasing stream flow and decreasing s ...

London Borough Of Hillingdon
The London Borough of Hillingdon () is the largest and westernmost borough in West London, England. It was formed from the districts of Hayes and Harlington, Ruislip-Northwood, Uxbridge, and Yiewsley and West Drayton in the ceremonial county of Middlesex. Today, Hillingdon is home to Heathrow Airport (which straddles the border between Hillingdon and Hounslow) and Brunel University, and is the second largest of the 32 London boroughs by area. The main towns in the borough are Hayes, Ruislip, Northwood, West Drayton and Uxbridge. Hillingdon is the second least densely populated of the London boroughs, due to a combination of large rural land in the north, RAF Northolt Aerodrome, and the large Heathrow Airport. Governance Administrative history The borough was formed in 1965 from the Hayes and Harlington Urban District, Municipal Borough of Uxbridge, Ruislip-Northwood Urban District, and Yiewsley and West Drayton Urban District, all formerly in the ceremonial county of Midd ...

Tributary
A tributary, or affluent, is a stream or river that flows into a larger stream or main stem (or parent) river or a lake. A tributary does not flow directly into a sea or ocean. Tributaries and the main stem river drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean. The Irtysh is a chief tributary of the Ob river and is also the longest tributary river in the world with a length of . The Madeira River is the largest tributary river by volume in the world with an average discharge of . A confluence, where two or more bodies of water meet, usually refers to the joining of tributaries. The opposite to a tributary is a distributary, a river or stream that branches off from and flows away from the main stream. PhysicalGeography.net, Michael Pidwirny & S ...

River
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as Stream#Creek, creek, Stream#Brook, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to Geographical feature, geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "Burn (landform), burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle. Water generally collects in a river from Precipitation (meteorology), precipitation through a ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

River Misbourne
The River Misbourne rises in a field on the outskirts of Great Missenden in Buckinghamshire, passing through Little Missenden, Old Amersham, Chalfont St Giles, Chalfont St Peter and under the Chiltern railway line and the M25 motorway to its confluence with the River Colne just north of where the Colne is crossed by Western Avenue, the A40 road. It falls by around in the course of its length. Etymology The name ''Misbourne'' is first attested, in the form ''Misseburne'', in 1407. The ''-bourne'' element is agreed to derive from Old English ''burna'' ('stream, river'), but the etymology of the first element is uncertain. It is thought to occur in the names of both Great and Little Missenden, and also in the Tring place-name Miswell. Frank Stenton and Allen Mawer guessed that it came from a hypothetical Anglo-Saxon personal name ''Myrsa'', which they also supposed to be found in the name of Mursley. Eilert Ekwall suggested that it came from a lost Old English word related to ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

River Chess
The River Chess is a chalk stream that rises near Chesham in the Chiltern Hills, and flows for through Buckinghamshire and Hertfordshire to its confluence with the River Colne, Hertfordshire, River Colne in Rickmansworth. The Chess, along with the River Colne, Hertfordshire, Colne and River Gade, Gade, gives rise to the name of the district of Three Rivers (district), Three Rivers. Etymology The name arose by back-formation from the town of Chesham Chesham (, , or ) is a market town and civil parish in Buckinghamshire, England, south-east of the county town of Aylesbury, north-west of central London, and part of the London commuter belt.

River Gade
The River Gade is a river running almost entirely through Hertfordshire. It rises from a spring in the chalk of the Chiltern Hills at Dagnall, Buckinghamshire and flows through Hemel Hempstead, Kings Langley, then along the west side of Watford through Cassiobury Park. After passing Croxley Green it reaches Rickmansworth, where it joins the River Colne. For its whole course the Gade is unnavigable. Its principal tributary is the River Bulbourne which joins it at Two Waters, just below Hemel Hempstead. The river was once used to power water mills, such as those at Water End, Cassiobury Park and Two Waters as well as powering the John Dickinson paper mills at Apsley and Croxley. It supported the farming of watercress at Cassiobury Park, Water End, the Grade 2 listeJellicoe Water Gardensand Two Waters until water was diverted from the river in 1947 to supply the growing new town of Hemel Hempstead. Below Hemel Hempstead it runs alongside and sometimes forms part of the ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
