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 ...

Syon Park
Syon Park is the garden of Syon House, the London home of the Duke of Northumberland in Brentford in the London Borough of Hounslow. It was landscaped by Capability Brown in the 18th century, and it is Grade I listed by English Heritage under the Historic Buildings and Ancient Monuments Act 1953 for its special historic interest. The main gardens are a Site of Borough Importance for Nature Conservation, Grade I, and the flood meadows next to the River Thames are a biological Site of Special Scientific Interest (SSSI) and a Site of Metropolitan Importance for Nature Conservation. History Syon was the site of Sion Abbey, which was founded in 1415 and named after Mount Zion in Jerusalem. It was dissolved in 1539. Foundations of the abbey were discovered in 2003. Landscaping of the gardens in the middle of the eighteenth century have left them with a collection of rare trees and plants and a lake which has a population of terrapins.

Hampton Court Palace
Hampton Court Palace is a Listed building, Grade I listed royal palace in the London Borough of Richmond upon Thames, southwest and upstream of central London on the River Thames. Opened to the public, the palace is managed by Historic Royal Palaces, a charity set up to preserve several unoccupied royal properties. The building of the palace began in 1514 for Cardinal Thomas Wolsey, Archbishop of York and the chief minister of Henry VIII. In 1529, as Wolsey fell from favour, the cardinal gave the palace to the king to try to save his own life, which he knew was now in grave danger due to Henry VIII's deepening frustration and anger. 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 it could accommodate his sizeable retinue of Courtier, courtiers. In the early 1690s, William III of England, William III's massive rebuilding and expansion work, which was intended to rival the Palace of V ...

Confluence
In geography, a confluence (also ''conflux'') occurs where two or more watercourses join to form a single channel (geography), 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 river source, source of a river of a new name (such as the confluence of the Monongahela River, Monongahela and Allegheny River, Allegheny rivers, forming the Ohio River); or where two separated channels of a river (forming a river island) rejoin downstream from their point of separation. Scientific study 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 [downstream o ...

Tributary
A tributary, or an ''affluent'', is a stream or river that flows into a larger stream (''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 into which they flow, drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean, another river, or into an endorheic basin. The Irtysh is a chief tributary of the Ob (river), 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.

River
A river is a natural stream of fresh water that flows on land or inside Subterranean river, caves towards another body of water at a lower elevation, such as an ocean, lake, or another river. A river may run dry before reaching the end of its course if it runs out of water, or only flow during certain seasons. Rivers are regulated by the water cycle, the processes by which water moves around the Earth. Water first enters rivers through precipitation, whether from rainfall, the Runoff (hydrology), runoff of water down a slope, the melting of glaciers or snow, or seepage from aquifers beneath the surface of the Earth. Rivers flow in channeled watercourses and merge in confluences to form drainage basins, or catchments, areas where surface water eventually flows to a common outlet. Rivers have a great effect on the landscape around them. They may regularly overflow their Bank (geography), banks and flood the surrounding area, spreading nutrients to the surrounding area.

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 wor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
River Chess
The River Chess is a chalk stream that rises near Chesham in the Chiltern Hills in England, and flows for through Buckinghamshire and Hertfordshire to its confluence with the River Colne, Hertfordshire, River Colne in Rickmansworth.

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 G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
