River Tavy
The Tavy () is a river on Dartmoor, Devon, England. The name derives from the Brythonic root "Tam", once thought to mean 'dark' but now generally understood to mean 'to flow'. It has given its name to the town of Tavistock and the villages of Mary Tavy and Peter Tavy. It is a tributary of the River Tamar and has as its own tributaries: * Collybrooke * River Burn *River Wallabrooke * River Lumburn *River Walkham At Tavistock it feeds a canal running to Morwellham Quay. Its mouth is crossed by the Tavy Bridge which carries the Tamar Valley railway line. Navigation The river is navigable inland as far as Lopwell, where a weir A weir or low head dam is a barrier across the width of a river that alters the flow characteristics of water and usually results in a change in the height of the river level.

River Walkham
The Walkham is a river whose source is on Dartmoor, Devon, England. It rises in the wide gap between Roos Tor and Great Mis Tor and flows almost due south for approximately leaving the tors and thus National Park behind then south-west for past Woodtown. The river then reaches a village, Horrabridge, with a small compact network of streets mainly on the south or left bank. It receives most of its tributaries which are unnamed headwaters along its south-flowing inception, draining the near side of two series of six tors (peaks) to the west ending in Pew Tor at 320 metres and likewise to the east ending in Leeden Tor at 389 metres (above mean sea level). In absolute distance, west of the village and the same south of the small well-preserved town of Tavistock by a footbridge on the West Devon Way the Walkham joins the Tavy which discharges into the Tamar Estuary north of the Plymouth conurbation after a fast descent around wide hillsides, a few miles south.

Rivers Of Devon
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 creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to 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" 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 through a drainage basin from surface runoff and other sources such as groundwater recharge, springs, ...

Tamar–Tavy Estuary
The Tamar–Tavy Estuary is a Site of Special Scientific Interest (SSSI) covering the tidal estuaries of the River Tamar and the River Tavy on the border between Cornwall and Devon in England, UK. Part of the Tamar estuary also forms the Tamar Estuary Nature Reserve, owned by the Cornwall Wildlife Trust. The site was designated in 1991 for its biodiversity and varying habitats that support many wader and wildfowl species, as well as the special interest of its marine biology. Geography The SSSI encompasses the entirety of the tidal regions of the Tamar; from Gunnislake down to the Tamar Bridge in the south, where it forms the Hamoaze, and the River Tavy from Lopwell to its discharge in the Tamar. The site also includes Kingsmill Lake, Tamerton Lake and a few other tributary streams of the Tamar, as well as the marshes around Morwellham Quay. The site forms part of the ''Tamar Estuaries Complex'' Special Protection Area (SPA), along with the estuary of the River Lynher and S ...

Ordnance Survey
Ordnance Survey (OS) is the national mapping agency for Great Britain. The agency's name indicates its original military purpose (see ordnance and surveying), which was to map Scotland in the wake of the Jacobite rising of 1745. There was also a more general and nationwide need in light of the potential threat of invasion during the Napoleonic Wars. Since 1 April 2015 Ordnance Survey has operated as Ordnance Survey Ltd, a government-owned company, 100% in public ownership. The Ordnance Survey Board remains accountable to the Secretary of State for Business, Energy and Industrial Strategy. It was also a member of the Public Data Group. Paper maps for walkers represent only 5% of the company's annual revenue. It produces digital map data, online route planning and sharing services and mobile apps, plus many other location-based products for business, government and consumers. Ordnance Survey mapping is usually classified as either " large-scale" (in other words, more detaile ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Devonport, Devon
Devonport ( ), formerly named Plymouth Dock or just Dock, is a district of Plymouth in the English county of Devon, although it was, at one time, the more important settlement. It became a county borough in 1889. Devonport was originally one of the " Three Towns" (along with Plymouth and East Stonehouse); these merged in 1914 to form what would become in 1928 the City of Plymouth. It is represented in the Parliament of the United Kingdom as part of the Plymouth Sutton and Devonport constituency. Its elected Member of Parliament (MP) is Luke Pollard, who is a member of the Labour Party. The population of the ward at the 2011 census was 14,788. History Plymouth Dock In 1690 the Admiralty gave a contract to Robert Waters from Portsmouth to build a stone dock at Point Froward on the east bank of the Hamoaze at the mouth of the River Tamar. Plymouth Dock, as Devonport was originally called, began around 1700 as a small settlement to house workers employed on the new naval base ...

Normal Tidal Limit
Head of tide, tidal limit or tidehead is the farthest point upstream where a river is affected by tidal fluctuations, or where the fluctuations are less than a certain amount. This applies to rivers which flow into tidal bodies such as oceans, bays and deltas. Though this point may vary due to storms, spring tides, and seasonal or annual differences in water flows, there is generally an average point that is accepted as the head of tide (in Great Britain this is the Normal Tidal Limit, typically noted on Ordnance Survey maps as 'NTL'). A river's tidal data are recorded at various locations downstream of this point. A river's head of tide may be considered the upper boundary of its estuary. The head of tide is important in surveying, navigation, and fisheries management, and thus many jurisdictions establish a legal head of tide. As the head of tide is useful for navigation, separate maps can be made of the tidal zones up to the head of tide, such as was done in New Jersey. Th ...

Weir
A weir or low head dam is a barrier across the width of a river that alters the flow characteristics of water and usually results in a change in the height of the river level. Weirs are also used to control the flow of water for outlets of lakes, ponds, and reservoirs. There are many weir designs, but commonly water flows freely over the top of the weir crest before cascading down to a lower level. Etymology There is no single definition as to what constitutes a weir and one English dictionary simply defines a weir as a small dam, likely originating from Middle English ''were'', Old English ''wer'', derivative of root of ''werian,'' meaning "to defend, dam". Function Commonly, weirs are used to prevent flooding, measure water discharge, and help render rivers more navigable by boat. In some locations, the terms dam and weir are synonymous, but normally there is a clear distinction made between the structures. Usually, a dam is designed specifically to impound water beh ...

Tamar Valley Line
The Tamar Valley Line is a railway line from Plymouth, Devon, to Gunnislake, Cornwall, in England, also known as the Gunnislake branch line. The line follows the River Tamar for much of its route. Like all railway lines in Devon and Cornwall, it is unelectrified and all trains are diesel powered. The entire line is single track past St. Budeaux Junction. History The line from St Budeaux to Bere Alston was opened for passenger traffic on 2 June 1890 by the Plymouth, Devonport and South Western Junction Railway (PDSWJ) as part of their line from Lydford to Devonport, which in effect was an extension of the London and South Western Railway's main line from London Waterloo station to Lydford, enabling the LSWR to reach Plymouth independently of the Great Western Railway. The branch to Gunnislake was opened by the PDSWJ on 2 March 1908. The line was listed for closure in the '' Reshaping of British Railways Report'' but was kept open (apart from the section between Gunnislake and ...
