Cae Llwyd Reservoir
Cae Llwyd is a reservoir located between Llwyneinion and the Ruabon Moors in Wrexham County Borough, Wales. Description The reservoir is an impounded lake holding raw water. It is dammed with a soil embankment consisting of a puddle clay core. It rises up to , holds a total water capacity of . The contract to build the reservoir was signed in 1875, with a cost of . The plans are described to be "commendably brief", only containing seven items. One of the drawings was later found in 1984 to have been drawn on the back of a print for various Mersey crossing proposals including a suspension bridge and two tunnels. The reservoir was constructed in 1878 by the Wrexham Waterworks Company, it is operated by Hafren Dyfrdwy on behalf of Severn Trent. The reservoir is part of the Ty Mawr/Cae Llwyd/ Pen-y-Cae Reservoir System, one of the two reservoir systems by Hafren Dyfrdwy to supply the Wrexham Resource Zone. There is a Scouting site located next to the reservoir. See als ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wrexham
Wrexham ( ; cy, Wrecsam; ) is a city and the administrative centre of Wrexham County Borough in Wales. It is located between the Welsh mountains and the lower Dee Valley, near the border with Cheshire in England. Historically in the county of Denbighshire, and later the county of Clwyd in 1974, it has been the principal settlement of Wrexham County Borough since 1996. Wrexham has historically been one of the primary settlements of Wales. At the 2011 Census, it had an urban population of 61,603 as part of the wider Wrexham built-up area which made it Wales's fourth largest urban conurbation and the largest in north Wales. The city comprises the local government communities of Acton, Caia Park, Offa and Rhosddu. Wrexham's built-up area extends further into villages like Bradley, Brymbo, Brynteg, Gwersyllt, New Broughton, Pentre Broughton and Rhostyllen. Wrexham was likely founded prior to the 11th century and developed in the Middle Ages as a regional centre for t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River Mersey
The River Mersey () is in North West England. Its name derives from Old English and means "boundary river", possibly referring to its having been a border between the ancient kingdoms of Mercia and Northumbria. For centuries it has formed part of the boundary between the Historic counties of England, historic counties of Lancashire and Cheshire. The Mersey starts at the confluence of the River Tame, Greater Manchester, River Tame and River Goyt in Stockport. It flows westwards through south Manchester, then into the Manchester Ship Canal at Irlam, becoming a part of the canal and maintaining its water levels. After it exits the canal, flowing towards Warrington where it widens. It then narrows as it passes between Runcorn and Widnes. From Runcorn the river widens into a large estuary, which is across at its widest point near Ellesmere Port. The course of the river then turns northwards as the estuary narrows between Liverpool and Birkenhead on the Wirral Peninsula to the west ...

List Of Lakes Of Wales
This is a list of lakes in Wales, including those created as reservoirs. The names of most lakes in Wales start with the word "''Llyn''", which is Welsh for "''lake''". Except where otherwise referenced, all lakes listed here are named on the relevant Ordnance Survey map at 1:25000 scale. By area In terms of surface area, the ten largest lakes in Wales are * Llyn Tegid (Bala Lake) — *Llyn Trawsfynydd — *Lake Vyrnwy — * Llyn Brenig — * Llyn Celyn — *Llyn Alaw — *Claerwen Reservoir — * Llyn Clywedog — * Nant y Moch Reservoir — *Caban Coch Reservoir — All of the above, with the exception of Llyn Tegid, are reservoirs held back by dams. Llyn Tegid was the largest natural lake in Wales though its level has been artificially controlled by sluices since about 1804. The largest natural lake in South Wales is Llangorse Lake (Llyn Syfaddan), which is also the second largest natural lake. By unitary authority This list of Welsh lakes ordered by unitary aut ...

Cold And Still - Geograph
Cold is the presence of low temperature, especially in the atmosphere. In common usage, cold is often a subjective perception. A lower bound to temperature is absolute zero, defined as 0.00K on the Kelvin scale, an absolute thermodynamic temperature scale. This corresponds to on the Celsius scale, on the Fahrenheit scale, and on the Rankine scale. Since temperature relates to the thermal energy held by an object or a sample of matter, which is the kinetic energy of the random motion of the particle constituents of matter, an object will have less thermal energy when it is colder and more when it is hotter. If it were possible to cool a system to absolute zero, all motion of the particles in a sample of matter would cease and they would be at complete rest in the classical sense. The object could be described as having zero thermal energy. Microscopically in the description of quantum mechanics, however, matter still has zero-point energy even at absolute zero, because ...

Scouting
Scouting, also known as the Scout Movement, is a worldwide youth movement employing the Scout method, a program of informal education with an emphasis on practical outdoor activities, including camping, woodcraft, aquatics, hiking, backpacking, and sports. Another widely recognized movement characteristic is the Scout uniform, by intent hiding all differences of social standing in a country and encouraging equality, with neckerchief and campaign hat or comparable headwear. Distinctive uniform insignia include the fleur-de-lis and the trefoil, as well as merit badges and other patches. In 1907, Robert Baden-Powell, a Lieutenant General in the British Army, held a Scouting encampment on Brownsea Island in England. Baden-Powell wrote '' Scouting for Boys'' (London, 1908), partly based on his earlier military books. The Scout Movement of both Boy Scouts and Girl Scouts was well established in the first decade of the twentieth century. Later, programs for younger children, such as ...

Tunnel
A tunnel is an underground passageway, dug through surrounding soil, earth or rock, and enclosed except for the entrance and exit, commonly at each end. A pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods. A tunnel may be for foot or vehicular road traffic, for rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel. Some tunnels are used as sewers or aqueducts to supply water for consumption or for hydroelectric stations. Utility tunnels are used for routing steam, chilled water, electrical power or telecommunication cables, as well as connecting buildings for convenient passage of people and equipment. Secret tunnels are built for military purposes, or by civilians for smuggling of weapons, contraband, or people. Special tunnels, such as wildlife crossings, are built to allow wildlife to cross human-made barriers safely. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Suspension Bridge
A suspension bridge is a type of bridge in which the deck (bridge), deck is hung below suspension wire rope, cables on vertical suspenders. The first modern examples of this type of bridge were built in the early 1800s. Simple suspension bridges, which lack vertical suspenders, have a long history in many mountainous parts of the world. Besides the bridge type most commonly called suspension bridges, covered in this article, there are other types of suspension bridges. The type covered here has cables suspended between towers, with vertical ''suspender cables'' that transfer the Structural load#Live load, imposed loads, transient load, live and Structural load#Dead load, dead loads of the deck below, upon which traffic crosses. This arrangement allows the deck to be level or to arc upward for additional clearance. Like other suspension bridge types, this type often is constructed without the use of falsework. The suspension cables must be anchored at each end of the bridge, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Puddle Clay
Puddling is both the material and the process of lining a water body such as a channel or pond with puddle clay (puddle, puddling) – a watertight (low hydraulic conductivity) material based on clay and water mixed to be workable. Puddle clay as a lining Puddling is used in maintaining canals or reservoirs on permeable ground. The technique of puddling and its use was developed by early canal engineer James Brindley; it is considered his greatest contribution to engineering. This processed material was used extensively in UK canal construction in the period starting circa 1780. Starting about 1840 puddle clay was used more widely as the water-retaining element (or core) within earthfill dams, particularly in the Pennines. Its usage in UK dams was superseded about 1960 by the use of rolled clay in the core, and better control of moisture content. A considerable number of early notable dams were built in that era and they are now sometimes referred to as the 'Pennines embankment' ...
