Lluest-wen Reservoir
Lluest-wen Reservoir (Welsh: ''Cronfa-ddwr Lluest-wen'') is a reservoir at the top of the Rhondda Fach Valley (Welsh: ''Cwm Rhondda Fach''), in the borough of Rhondda Cynon Taf, South Wales. Parts of it fall within the communities of Rhigos, Aberdare and Treherbert. A recreational walking route, the Coed Morgannwg Way, and route 47 of the National Cycle Network run northeast and southwest of it respectively. The reservoir gained national attention in 1969 when significant damage was discovered that led to the evacuation of hundreds of nearby homes and prompted more than £1 million of emergency repair works. Geography and construction The reservoir was built in 1898 and covers an area of . It was located at the top of the Rhondda Fach, near the village of Maerdy. The site holds around of water. The dam was built using earth embankments, the core of which were constructed of clay. The banks were reinforced during the early 1970s with thick concrete. History Construction of th ...

Rhondda
Rhondda , or the Rhondda Valley ( cy, Cwm Rhondda ), is a former coalmining area in South Wales, historically in the county of Glamorgan. It takes its name from the River Rhondda, and embraces two valleys – the larger Rhondda Fawr valley (''mawr'' large) and the smaller Rhondda Fach valley (''bach'' small) – so that the singular "Rhondda Valley" and the plural are both commonly used. The area forms part of the South Wales Valleys. From 1897 until 1996 there was a local government district of Rhondda. The former district at its abolition comprised sixteen communities. Since 1996 these sixteen communities of the Rhondda have been part of Rhondda Cynon Taf County Borough. The area of the former district is still used as the Rhondda Senedd constituency and Westminster constituency, having an estimated population in 2020 of 69,506. It is most noted for its historical coalmining industry, which peaked between 1840 and 1925. The valleys produced a strong Nonconformist movemen ...

Reservoirs In Rhondda Cynon Taf
A reservoir (; from French ''réservoir'' ) is an enlarged lake behind a dam. Such a dam may be either artificial, built to store fresh water or it may be a natural formation. Reservoirs can be created in a number of ways, including controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, through excavation, or building any number of retaining walls or levees. In other contexts, "reservoirs" may refer to storage spaces for various fluids; they may hold liquids or gasses, including hydrocarbons. ''Tank reservoirs'' store these in ground-level, elevated, or buried tanks. Tank reservoirs for water are also called cisterns. Most underground reservoirs are used to store liquids, principally either water or petroleum. Types Dammed valleys Dammed reservoirs are artificial lakes created and controlled by a dam constructed across a valley, and rely on the natural topography to provide most of the basin of the re ...

George Thomas, 1st Viscount Tonypandy
Thomas George Thomas, 1st Viscount Tonypandy, (29 January 1909 – 22 September 1997) was a British politician who served as a member of parliament (MP) and Speaker of the House of Commons from 1976 to 1983. He was elected as a Labour MP. Born in Port Talbot, South Wales, he initially worked as a teacher in both London and Cardiff. A MP from 1945 to 1983, he held office in Harold Wilson's 1964–1970 Labour administration, notably as Secretary of State for Wales from 1968 to 1970. As a junior minister at the Welsh Office, he was one of the first on the scene of the Aberfan disaster (21 October 1966), and was later involved in the controversial government decision to use money from the Aberfan Charity Fund to clear remaining National Coal Board waste tips from around the village. In 1976 Thomas was elected Speaker, in which role the first broadcasting of parliamentary proceedings brought him unprecedented public attention. He is the most recent Speaker to have served as a gove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reservoirs Act 1975
Reservoirs storing large volumes of water have the capability of causing considerable damage and loss of life if they fail. Reservoirs are considered "installations containing dangerous forces" under international humanitarian law because of their potential adverse impact. In 1975 the failure of the Banqiao Reservoir Dam and other dams in Henan Province, China caused more casualties than any other dam failures in history. The disaster killed an estimated 171,000 people and 11 million people lost their homes. Because reservoirs and their containing dams present such significant potential risks many countries have put legislation in place and set safety standards, but it was not until 1930 that effective legislation was first approved for control of the design, construction and maintenance of dams and reservoirs when the Reservoirs (Safety provisions) Act, 1930 was enacted in the United Kingdom. Causes of failure Although failure is often portrayed as a catastrophic failure of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bentonite
Bentonite () is an absorbent swelling clay consisting mostly of montmorillonite (a type of smectite) which can either be Na-montmorillonite or Ca-montmorillonite. Na-montmorillonite has a considerably greater swelling capacity than Ca-montmorillonite. Bentonite usually forms from the weathering of volcanic ash in seawater, or by hydrothermal circulation through the porosity of volcanic ash beds, which converts (devitrification) the volcanic glass ( obsidian, rhyolite, dacite) present in the ash into clay minerals. In the mineral alteration process, a large fraction (up to 40-50 wt.%) of amorphous silica is dissolved and leached away, leaving the bentonite deposit in place. Bentonite beds are white or pale blue or green (traces of reduced ) in fresh exposures, turning to a cream color and then yellow, red, or brown (traces of oxidized ) as the exposure is weathered further. As a swelling clay, bentonite has the ability to absorb large quantities of water, which increa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Air Force
The Royal Air Force (RAF) is the United Kingdom's air and space force. It was formed towards the end of the First World War on 1 April 1918, becoming the first independent air force in the world, by regrouping the Royal Flying Corps (RFC) and the Royal Naval Air Service (RNAS). Following the Allied victory over the Central Powers in 1918, the RAF emerged as the largest air force in the world at the time. Since its formation, the RAF has taken a significant role in British military history. In particular, it played a large part in the Second World War where it fought its most famous campaign, the Battle of Britain. The RAF's mission is to support the objectives of the British Ministry of Defence (MOD), which are to "provide the capabilities needed to ensure the security and defence of the United Kingdom and overseas territories, including against terrorism; to support the Government's foreign policy objectives particularly in promoting international peace and security". The R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maerdy Colliery
Maerdy Colliery was a coal mine located in the South Wales village of Maerdy ( cy, Y Maerdy), in the Rhondda Valley, located in the county borough of Rhondda Cynon Taf, and within the historic county boundaries of Glamorgan, Wales. Opened in 1875, it closed in December 1990. History Maerdy derives its name from a large farmhouse on a bank of the Rhondda Fach, which became the local meeting place for both court matters and worship. Maerdy is the Welsh word for ''mayor's house''. While other areas of the South Wales coalfield had been exploited up to 50 years earlier, due to the scarcity and difficult access conditions of Rhondda Fach, it remained largely undeveloped. But the demand for steam coal drove development and, in 1874, Mordecai Jones of Brecon and Nantmelyn purchased the mineral rights around the farmhouse and its surrounding lands from the estate of the late Crawshay Bailey for £122,000. Additional capital was provided by a partner, J. R. Cobb, and a trial pit was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maerdy
Maerdy (, cy, Y Maerdy) is a village and community (and electoral ward) in the county borough of Rhondda Cynon Taf, and within the historic county boundaries of Glamorgan, Wales, lying at the head of the Rhondda Fach Valley. History "Maerdy" is a Welsh word meaning "house of the STEWARD", and may indicate a medieval origin. The "maer" (steward) was usually appointed by the king; the ''maer biswail'' (literally the "dung steward") was not as important and wielded less authority than the "maer" (''Hen Gyfreithiau Cymreig'', S. J. Williams). "Maerdy" was also used for a 'summer dwelling' as well as for a 'dairy farm' (GPC). The name is found in several locations throughout Wales. 'Mardy' represents the local Gwentian dialect form of the written "maerdy". The area grew from a farming community to town around the coal mining industry and the development of Mardy Colliery in the late 19th century, but its last pit (Mardy Main) shut in 1990. Maerdy was not originally an area of indus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Cycle Network
The National Cycle Network (NCN) is the national cycling route network of the United Kingdom, which was established to encourage cycling and walking throughout Britain, as well as for the purposes of bicycle touring. It was created by the charity Sustrans who were aided by a £42.5 million National Lottery grant. However Sustrans themselves only own around 2% of the paths on the network, these rest being made of existing public highways and rights of way, and permissive paths negotiated by Sustrans with private landowners, which Sustrans have then labelled as part of their network. In 2017, the Network was used for over 786 million cycling and walking trips, made by 4.4 million people. In 2020, around a quarter the NCN was scrapped on safety grounds, leaving of signed routes. These are made up of of traffic-free paths with the remaining on-road. It uses shared use paths, disused railways, minor roads, canal towpaths and traffic-calmed routes in towns and cit ...

Coed Morgannwg Way
Mixed-sex education, also known as mixed-gender education, co-education, or coeducation (abbreviated to co-ed or coed), is a system of education where males and females are educated together. Whereas single-sex education was more common up to the 19th century, mixed-sex education has since become standard in many cultures, particularly in Western countries. Single-sex education remains prevalent in many Muslim countries. The relative merits of both systems have been the subject of debate. The world's oldest co-educational school is thought to be Archbishop Tenison's Church of England High School, Croydon, established in 1714 in the United Kingdom, which admitted boys and girls from its opening onwards. This has always been a day school only. The world's oldest co-educational both day and boarding school is Dollar Academy, a junior and senior school for males and females from ages 5 to 18 in Scotland, United Kingdom. From its opening in 1818, the school admitted both boys and gi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
