Flash Lock
A flash lock is a type of lock (water transport), lock for river or canal transport. Early locks were designed with a single gate, known as a flash lock or staunch lock. The earliest European references to what were clearly flash locks were in Roman times. Development In England the "gate" was similar to a temporary needle dam: a set of boards, called ''paddles'', supported against the current by upright timbers called ''rymers'' which normally kept the level of water above it to navigable levels. Boats moving downstream would wait above the lock until the paddles (and their rymers) were removed, which would allow a "flash" of water to pass through, carrying the boats with it. Boats moving upstream would be winched or towed through the lock with the paddles removed. Considerable skill was involved both in removing the paddles in a timely manner and navigating the boat through the lock. Flash locks of this type have been Science and technology of the Song dynasty#Civil enginee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lock (water Transport)
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 chamber in a permanently fixed position in which the water level can be varied. (In a caisson lock, a boat lift, or on a canal inclined plane, it is the chamber itself (usually then called a caisson (engineering), 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. Over time, more and larger locks have been used in canals to allow a more direct route to be taken. History Ancient Egypt In Ancient Egypt, the river-locks was probably part of the Canal of the Pharaohs: Ptolemy II is credited by some for being the first to solve the problem of keeping the Nile free of salt water when his engineers invented the lock around 274/273 BC. Ancient China During 960–1279 CE, the natural extension o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Streatley, Berkshire
Streatley is a village and civil parishes in England, civil parish on the River Thames in Berkshire, England. The village faces Goring-on-Thames. The two places share in their shops, services, leisure, sports and much of their transport. Across the river is railway station and the village cluster adjoins Goring Lock, a lock and weir. The west of the village is a mixture of agriculture and woodland plus a golf course. The village has a riverside hotel. Much of Streatley is at steeply varying elevations, ranging from Ordnance datum, above ordnance datum (AOD) at Streatley Warren, a hilltop point on its western border forming the eastern end of the Berkshire Downs. This Area of Outstanding Natural Beauty is topped by the The Ridgeway path, which crosses the Thames at Goring and Streatley Bridge. Location Streatley is centred north-west of Reading, Berkshire, Reading and south of Oxford. Its developed area occupies half of the narrow Goring Gap on the River Thames and is directl ...

Goring-on-Thames
Goring-on-Thames (or Goring) is a village and civil parish on the River Thames in South Oxfordshire, England. Situated on the county border with Berkshire, it is south of Wallingford and north-west of Reading. It had a population of 3,187 in the 2011 census and was estimated to have increased to 3,335 by 2019. Most land is farmland, with woodland on the Goring Gap outcrop of the Chiltern Hills.

Rushey Lock
Rushey Lock is a lock on the River Thames in England. It is on the northern bank of the river in Oxfordshire, at a considerable distance from any village, the nearest being Buckland Marsh, a hamlet on the road to Buckland to the south of the river. The lock was built in stone in 1790 by the Thames Navigation Commission. The weir is adjacent to the lock on the other side of the lock island. History There was originally a weir and flash lock about a mile upstream called Old Nan's Weir. A survey made in 1790 concluded that the site was unsuitable for a pound lock, and it was built at Rushey instead. There is no record of an earlier weir or lock at Rushey. Keepers at Rushey had oversight of Old Nan's Weir which was finally removed in 1868. Rushey lock was reported as in a bad state of deterioration in 1857 and the weir also in 1871, repairs being needed on both occasions. The lock keeper's house with a pyramidical roof was built in 1894, replacing an older one, and the lock ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River Kennet
The Kennet is a tributary of the River Thames in Southern England. Most of the river is straddled by the North Wessex Downs AONB (Area of Outstanding Natural Beauty). The lower reaches have been made navigable as the Kennet Navigation, which – together with the Avon Navigation, the Kennet and Avon Canal and the Thames – links the cities of Bristol and London. The length from near its sources west of Marlborough, Wiltshire, Marlborough, Wiltshire down to Woolhampton, Berkshire is a biological Site of Special Scientific Interest (SSSI). This is primarily from an array of rare plants and animals completely endemism, endemic to chalky watercourses. When Wiltshire had second-tier local authorities, one, Kennet District, took the name of the river. Etymology The pronunciation (and spelling) was as the Kunnit (or Cunnit). This is likely derived from the Roman settlement in the upper valley floor, Cunetio (in the later large village of Mildenhall, Wiltshire, Mildenhall). Latin s ...

Blake's Lock
Blake's Lock is a lock situated on the River Kennet in Reading, Berkshire, England. It is on the short reach of the River Kennet which is administered as if it were part of the River Thames and is hence owned and managed by the Environment Agency. History The first mile of the Kennet from its junction with the River Thames has been navigable since the 13th century. Blake's Lock was originally a flash lock known as Brokenburglok. In 1404 the Abbot of Reading Abbey, who had control of the River Kennet, made an agreement with the town's guild to allow craft to pass through the lock between sunrise and sunset on payment of a one penny toll. By 1794, not much had changed, with John Rennie, the engineer of the Kennet and Avon Canal describing it as "a very bad and inconvenient staunch lock". The lock was converted to a timber-constructed pound lock in 1802 to improve navigation from the Thames into the River Kennet enabling boats to travel all the way to the Bristol area. Th ...

Hydraulics
Hydraulics () is a technology and applied science using engineering, chemistry, and other sciences involving the mechanical properties and use of liquids. At a very basic level, hydraulics is the liquid counterpart of pneumatics, which concerns gases. Fluid mechanics provides the theoretical foundation for hydraulics, which focuses on applied engineering using the properties of fluids. In its fluid power applications, hydraulics is used for the generation, control, and transmission of Power (physics), power by the use of pressure, pressurized liquids. Hydraulic topics range through some parts of science and most of engineering modules, and they cover concepts such as pipe Volumetric flow rate, flow, dam design, fluidics, and fluid control circuitry. The principles of hydraulics are in use naturally in the human body within the vascular system and erectile tissue. ''Free surface hydraulics'' is the branch of hydraulics dealing with free surface flow, such as occurring in rivers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
