Desborough Cut
The Desborough Cut is an artificial channel in the River Thames above Sunbury Lock near Walton on Thames in England. It was completed in 1935, to improve flow and ease navigation on the river. The cut was dug between 1930 and 1935, taking the river on a straight course between Weybridge and Walton, and avoiding a meandering stretch past Shepperton and Lower Halliford. It is a very slight curve long. Its geodesic, geodesic length is as the crow flies, and its construction created Desborough Island. Two bridges were built across the cut to link to the island, which contains a water treatment works and a large extent of open space used for recreation. The cut alleviated flooding in Shepperton and halved the distance of travel on that part of the river. The cut creates a rare stretch on the River Thames, Thames having alternative main navigation channels and is the longest such alternative. Navigation transit markers stand alongside it as a traditional method for powered boats to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River Thames
The River Thames ( ), known alternatively in parts as the The Isis, River Isis, is a river that flows through southern England including London. At , it is the longest river entirely in England and the Longest rivers of the United Kingdom, second-longest in the United Kingdom, after the River Severn. The river rises at Thames Head in Gloucestershire, and flows into the North Sea near Tilbury, Essex and Gravesend, Kent, via the Thames Estuary. From the west it flows through Oxford (where it is sometimes called the Isis), Reading, Berkshire, Reading, Henley-on-Thames and Windsor, Berkshire, Windsor. The Thames also drains the whole of Greater London. In August 2022, the source of the river moved five miles to beyond Somerford Keynes due to the heatwave in July 2022. The lower reaches of the river are called the Tideway, derived from its long tidal reach up to Teddington Lock. Its tidal section includes most of its London stretch and has a rise and fall of .

Sunbury Lock
Sunbury Lock is a lock complex of the River Thames in England near Walton-on-Thames in north-west Surrey, the third lowest of forty four on the non-tidal reaches. The complex adjoins the right, southern bank about downstream of the Weir Hotel. The complex is two locks, old and new, and a narrow concrete divide, which are downstream of the original lock built in 1812. The older, hand-operated, was originally built in 1856, seldom used. The newer was opened in 1927 by Lord Desborough. Rollers and a slope adjoins for the portage (hauling) of small boats. The lock adjoins Sunbury Lock Ait. The lock has three associated weirs, upstream. The main weir is between Sunbury Lock Ait and Wheatley's Ait (north); the latter has two other weirs, one is a small part-time storm weir. History The earliest major weir locally was built in 1789 specifically to divert water to create a deeper channel for navigation. Other such weirs locally were in place since medieval times because of man ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Walton On Thames
Walton-on-Thames, locally known as Walton, is a market town on the south bank of the Thames in the Elmbridge borough of Surrey, England. Walton forms part of the Greater London built-up area, within the KT postcode and is served by a wide range of transport links. According to the 2011 Census, the town has a total population of 22,834. The town itself consists mostly of affluent suburban streets, with a historic town centre of Celtic origin. It is one of the largest towns in the Elmbridge borough, alongside Weybridge. History The name "Walton" is Anglo-Saxon in origin and is cognate with the common phonetic combination meaning "Briton settlement" (literally, "Welsh Town" – weal(as) tun). Before the Romans and the Saxons were present, a Celtic settlement was here. The most common Old English word for the Celtic inhabitants was the "Wealas", originally meaning "foreigners" or "strangers". William Camden identified Cowey Stakes or Sale, Walton as the place where Julius Cae ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weybridge
Weybridge () is a town in the Borough of Elmbridge in Surrey, England, around southwest of central London. The settlement is recorded as ''Waigebrugge'' and ''Weibrugge'' in the 7th century and the name derives from a crossing point of the River Wey, which flows into the River Thames to the north of the town centre. The earliest evidence of human activity is from the Bronze Age. During the Anglo-Saxon and medieval periods, Weybridge was held by Chertsey Abbey. In the 1530s, Henry VIII constructed Oatlands Palace to the north of the town centre, which he intended to be the residence of his fourth wife, Anne of Cleves. He married Catherine Howard there in July 1540 and the palace remained a royal residence until the Civil War. The buildings were demolished in the early 1650s and a new mansion, Oatlands House, was constructed to the east of Weybridge later the same century. Prince Frederick, Duke of York and Albany owned the mansion in the 18th century. The town began to ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shepperton
Shepperton is an urban village in the Borough of Spelthorne, Surrey, approximately south west of central London. Shepperton is equidistant between the towns of Chertsey and Sunbury-on-Thames. The village is mentioned in a document of 959 AD and in the Domesday Book. In the early 19th century, resident writers and poets included Rider Haggard, Thomas Love Peacock, George Meredith and Percy Bysshe Shelley, who were attracted by the proximity of the River Thames. The river was painted at Walton Bridge in 1754 by Canaletto and in 1805 by Turner. Shepperton Lock and nearby Sunbury Lock were built in the 1810s to facilitate river navigation. Urbanisation began in the latter part of the 19th century, with the construction in 1864 of the Shepperton Branch Line, which was sponsored by William Schaw Lindsay, the owner of Shepperton Manor. Its population rose from 1,810 residents in the early 20th century to a little short of 10,000 in 2011. Lindsay had hoped to extend the railw ...

Geodesic
In geometry, a geodesic () is a curve representing in some sense the shortest path ( arc) between two points in a surface, or more generally in a Riemannian manifold. The term also has meaning in any differentiable manifold with a connection. It is a generalization of the notion of a "straight line". The noun '' geodesic'' and the adjective ''geodetic'' come from ''geodesy'', the science of measuring the size and shape of Earth, though many of the underlying principles can be applied to any ellipsoidal geometry. In the original sense, a geodesic was the shortest route between two points on the Earth's surface. For a spherical Earth, it is a segment of a great circle (see also great-circle distance). The term has since been generalized to more abstract mathematical spaces; for example, in graph theory, one might consider a geodesic between two vertices/nodes of a graph. In a Riemannian manifold or submanifold, geodesics are characterised by the property of having vanishin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
As The Crow Flies
__NOTOC__ The expression ''as the crow flies'' is an idiom for the most direct path between two points, rather similar to "in a beeline". This meaning is attested from the early 19th century, and appeared in Charles Dickens's 1838 novel '' Oliver Twist'': Crows do conspicuously fly alone across open country, but neither crows nor bees (as in "beeline") fly in particularly straight lines.Villazon, Luis.“Do crows actually fly in a straight line?” BBC Focus (August 30, 2017). While crows do not swoop in the air like swallows or starlings, they often circle above their nests. One suggested origin of the term is that before modern navigational methods were introduced, cages of crows were kept upon ships and a bird would be released from the crow's nest when required to assist navigation, in the hope that it would fly directly towards land. However, the earliest recorded uses of the term are not nautical in nature, and the crow's nest of a ship is thought to derive from its sha ...

Desborough Island
Desborough Island is a manmade island in the River Thames on the reach above Sunbury Lock in Surrey, England. It was formed in the 1930s by the digging of a channel – the Desborough Cut – by the Thames Conservancy as a meander cutoff of narrow width on the right bank. The island and cut are named after Lord Desborough, a chairman of the Thames Conservancy. Construction The –mile (1–km) Desborough Cut takes the Thames directly between the brief Weybridge bank to the upper (south) part of the Walton bank — creating Desborough Island between it and the river meanders which front much of Old Shepperton and Lower Halliford in Shepperton. The meanders remain navigable. They are of similar width to the cut. The cut alleviated flooding at Hamm Court and in Shepperton and halves the distance of travel from its start to its finish. Uses The island is almost uninhabited: mainly open space, playing fields and water treatment facilities. The island has access over ...

Navigation Transit Markers
Navigation Transit Markers are posts placed alongside a navigation to allow powered craft to check their speed. Examples of these markers can be found at several locations along the River Thames in England. A navigation marker consists of a black and white ringed pole surmounted by a red open triangle. The configuration of the markers is made up of two pairs, each pair having one pole behind the other, and the pairs being separated by a set distance along the bank. Timing starts when the first two markers line up, and ends when the second pair line up. For a craft to be within the speed limit, it should take a minute or more to reach the second pair of markers after passing the first pair of markers. On the upper reaches of the Thames, the speed limit is 8 km per hour or 133.3 m per minute, and so the markers are set 133.3 m apart. On the River Thames, there are markers on the reaches above Teddington Lock, Sunbury Lock, Cookham Lock, Sonning Lock, Day's Lock and O ...
