Wilton Water
Wilton Water (or Wide Waters) is a small reservoir, southwest of the village of Great Bedwyn in the English county of Wiltshire, which supplies the summit pound of the Kennet and Avon Canal with water. The reservoir lies in the parish of Grafton and collects rainfall from the eastern end of the Vale of Pewsey and the surrounding hills. It was created by John Blackwell in 1836, by damming a narrow branching valley, and is fed by natural springs. In addition to supplying water for the canal, which is pumped by Crofton Pumping Station, it provides a haven for wildlife. It has been stocked with rainbow trout. When the canal was built, there were no reliable water sources available to fill the summit by normal gravitational means. However, a set of usable springs were found adjacent to the canal route about one mile (2 km) east of the summit pound, and about 40 feet (12 m) below it. Arrangements were made for these springs to feed the pound below lock 60 at Crofton Locks. Some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crofton Pumping Station
Crofton Pumping Station, near the village of Great Bedwyn in Wiltshire, England, supplies the summit pound of the Kennet and Avon Canal with water. The steam-powered pumping station is preserved and operates on selected weekends. It contains an operational Boulton & Watt steam engine dating from 1812, making it the oldest working beam engine in the world in its original engine house and capable of doing the job for which it was installed. Description When the canal was built, no reliable water sources were available to fill the summit by normal gravitational means. However, a set of usable springs were found adjacent to the canal route about east of the summit pound, and about below it. Arrangements were made for these springs to feed the pound below lock 60 at Crofton Locks. Some years later a reservoir (Wilton Water) was created to improve the supply to this pound, and this can now be seen across the canal from the pumping station. Water from below lock 60 was taken ...

Canal Lock
A lock is a device used for raising and lowering boats, ships and other watercraft between stretches of water of different levels on river and canal waterways. The distinguishing feature of a lock is a fixed chamber in which the water level can be varied; whereas in a caisson lock, a boat lift, or on a canal inclined plane, it is the chamber itself (usually then called a caisson) that rises and falls. Locks are used to make a river more easily navigable, or to allow a canal to cross land that is not level. Later canals used more and larger locks to allow a more direct route to be taken. Pound lock A ''pound lock'' is most commonly used on canals and rivers today. A pound lock has a chamber with gates at both ends that control the level of water in the pound. In contrast, an earlier design with a single gate was known as a flash lock. Pound locks were first used in China during the Song Dynasty (960–1279 AD), having been pioneered by the Song politician and naval en ...

History Of The British Canal System
History (derived ) is the systematic study and the documentation of the human activity. The time period of event before the invention of writing systems is considered prehistory. "History" is an umbrella term comprising past events as well as the memory, discovery, collection, organization, presentation, and interpretation of these events. Historians seek knowledge of the past using historical sources such as written documents, oral accounts, art and material artifacts, and ecological markers. History is not complete and still has debatable mysteries. History is also an academic discipline which uses narrative to describe, examine, question, and analyze past events, and investigate their patterns of cause and effect. Historians often debate which narrative best explains an event, as well as the significance of different causes and effects. Historians also debate the nature of history as an end in itself, as well as its usefulness to give perspective on the problems of the p ...

Canals Of The United Kingdom
The canals of the United Kingdom are a major part of the network of inland waterways in the United Kingdom. They have a varied history, from use for irrigation and transport, through becoming the focus of the Industrial Revolution, to today's role of recreational boating. Despite a period of abandonment, today the canal system in the United Kingdom is again increasing in use, with abandoned and derelict canals being reopened, and the construction of some new routes. Canals in England and Wales are maintained by navigation authorities. The biggest navigation authorities are the Canal & River Trust and the Environment Agency, but other canals are managed by companies, local authorities or charitable trusts. The majority of canals in the United Kingdom can accommodate boats with a length of between and are now used primarily for leisure. There are a number of canals which are far larger than this, including New Junction Canal and the Gloucester and Sharpness Canal, which can acc ...

Grade II Listed
In the United Kingdom, a listed building or listed structure is one that has been placed on one of the four statutory lists maintained by Historic England in England, Historic Environment Scotland in Scotland, in Wales, and the Northern Ireland Environment Agency in Northern Ireland. The term has also been used in the Republic of Ireland, where buildings are protected under the Planning and Development Act 2000. The statutory term in Ireland is " protected structure". A listed building may not be demolished, extended, or altered without special permission from the local planning authority, which typically consults the relevant central government agency, particularly for significant alterations to the more notable listed buildings. In England and Wales, a national amenity society must be notified of any work to a listed building which involves any element of demolition. Exemption from secular listed building control is provided for some buildings in current use for worship, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crofton Locks
Crofton Locks are a flight of locks on the Kennet and Avon Canal, near the village of Great Bedwyn, Wiltshire, England. The nine locks achieve a total rise/fall of 61 ft 0 in (18.5 m) and were built under the supervision of engineer John Rennie. West of the top lock is the summit of the canal at 450 ft (137 m) above sea level. Lockage water is taken from Wilton Water to the summit at the western end of the locks by electric pumps and, on occasion, by the restored Crofton Pumping Station. Location Although named for Crofton in the civil parish of Great Bedwyn the locks are actually situated in the parish of Grafton, as the parish boundary at this point is the West of England Main Line to the north of the canal. References See also *Locks on the Kennet and Avon Canal The Kennet and Avon Canal is a canal in southern England. The name may refer to either the route of the original Kennet and Avon Canal Company, which linked the River Kennet at Newbury to the Ri ...

Spring (hydrosphere)
A spring is a point of exit at which groundwater from an aquifer flows out on top of Earth's crust (pedosphere) and becomes surface water. It is a component of the hydrosphere. Springs have long been important for humans as a source of fresh water, especially in arid regions which have relatively little annual rainfall. Springs are driven out onto the surface by various natural forces, such as gravity and hydrostatic pressure. Their yield varies widely from a volumetric flow rate of nearly zero to more than for the biggest springs. Formation Springs are formed when groundwater flows onto the surface. This typically happens when the groundwater table reaches above the surface level. Springs may also be formed as a result of karst topography, aquifers, or volcanic activity. Springs also have been observed on the ocean floor, spewing hot water directly into the ocean. Springs formed as a result of karst topography create karst springs, in which ground water travels throu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wiltshire
Wiltshire (; abbreviated Wilts) is a historic and ceremonial county in South West England with an area of . It is landlocked and borders the counties of Dorset to the southwest, Somerset to the west, Hampshire to the southeast, Gloucestershire to the north, Oxfordshire to the northeast and Berkshire to the east. The county town was originally Wilton, after which the county is named, but Wiltshire Council is now based in the county town of Trowbridge. Within the county's boundary are two unitary authority areas, Wiltshire and Swindon, governed respectively by Wiltshire Council and Swindon Borough Council. Wiltshire is characterised by its high downland and wide valleys. Salisbury Plain is noted for being the location of the Stonehenge and Avebury stone circles (which together are a UNESCO Cultural and World Heritage site) and other ancient landmarks, and as a training area for the British Army. The city of Salisbury is notable for its medieval cathedral. Swindon is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Blackwell (engineer)
John Blackwell (c. 1775 – 1840) was an English civil engineer, known for his work as superintending engineer of the Kennet and Avon Canal under John Rennie and later as the canal company's resident engineer. Career Blackwell was employed as an engineer on the Kennet and Avon Canal in 1806, working primarily as site agent on the Caen Hill Flight in Devizes, Wiltshire. While John Rennie designed the flight, it was likely that construction was undertaken by the Kennet and Avon Canal Company and its engineers. In 1808, shortly before the completion of the flight, Blackwell moved to work with Rennie on Crofton Pumping Station. The following year, the pair built the remaining locks on the canal—two pound locks Oakhill Down near Froxfield, which replaced an earlier single deeper lock. Original plans would have seen the lock be the canal's only staircase, although this proposal was never seen through. Blackwell was appointed the company's resident engineer on 19 July 181 ...

Vale Of Pewsey
The Vale of Pewsey or Pewsey Vale is an area of Wiltshire, England to the east of Devizes and south of Marlborough, centred on the village of Pewsey. Geography The vale is an extent of lower lying ground separating the chalk downs of Salisbury Plain to the south from the Marlborough Downs to the north. It is around long and around wide. At the western end is the town of Devizes. Larger settlements in the vale include Pewsey and Burbage with many smaller villages, the larger ones including Bishops Cannings, Etchilhampton, Urchfont, Chirton, Alton Priors, Woodborough, Milton Lilbourne, Easton Royal and Wootton Rivers. Although not itself part of the downs, the vale is included as part of the North Wessex Downs AONB (Area of Outstanding Natural Beauty). The vale is a major east–west feature opening to the west towards the Bristol Channel, but is drained by the headwaters of the Salisbury Avon, rather than the westward-flowing Bristol Avon. The river cuts through the chalk ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
