Llyn Celyn
Llyn Celyn () is a reservoir constructed between 1960 and 1965 in the valley of the River Tryweryn in Gwynedd, Wales. It measures roughly long by wide, and has a maximum depth of . It has the capacity to hold of water. It was originally to be named ''Llyn Tryweryn Mawr'' (meaning "great Tryweryn lake"), but in September 1964 Liverpool Corporation agreed to the name change following a letter from the Tryweryn Defence Committee. Construction and opposition Construction of the reservoir for Liverpool Corporation Waterworks involved flooding the village of Capel Celyn and adjacent farmland, a deeply controversial move. Much of the opposition was brought about because the village was a stronghold of Welsh culture and the Welsh language, whilst the reservoir was being built to supply water to Liverpool and parts of the Wirral peninsula, rather than Wales. Liverpool Corporation's Tryweryn Reservoir Bill was presented in Parliament as a private bill in January 1957; by obtain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Welsh Nationalism
Welsh nationalism ( cy, Cenedlaetholdeb Cymreig) emphasises and celebrates the distinctiveness of Welsh culture and Wales as a nation or country. Welsh nationalism may also include calls for further autonomy or self determination which includes Welsh devolution, meaning increased powers for the Senedd, or full Welsh independence. History English rule in Wales Through most of its history before the Anglo-Norman Conquest, Wales was divided into several kingdoms. From time to time, rulers such as Hywel Dda, Gruffudd ap Llywelyn and Rhodri the Great managed to unify many of the kingdoms, but their lands were divided on their deaths. Wales first appeared as a unified independent country in 1055 under the leadership of the only King of Wales to have controlled all the territories of Wales, Gruffydd ap Llywelyn until 1063. Three years later the Norman invasion began which briefly controlled much of Wales, but by 1100 Anglo-Normans control was reduced to the lowland Gwent, Glam ...

Snowdonia
Snowdonia or Eryri (), is a mountainous region in northwestern Wales and a national park of in area. It was the first to be designated of the three national parks in Wales, in 1951. Name and extent It was a commonly held belief that the name is derived from ("eagle"), and thus means "the abode/land of eagles", but recent evidence is that it means ''highlands'', and is related to the Latin (to rise) as leading Welsh scholar Sir proved. The term first appeared in a manuscript in the 9th-century , in an account of the downfall of the semi-legendary 5th-century king (Vortigern). In the Middle Ages, the title ''Prince of Wales and Lord of Snowdonia'' () was used by ; his grandfather used the title ''Prince of north Wales and Lord of Snowdonia.'' The name ''Snowdonia'' derives from '' Snowdon'', the highest mountain in the area and the highest mountain in Wales at . Before the boundaries of the national park were designated, "Snowdonia" was generally used to refer to a sm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gravity Dam
A gravity dam is a dam constructed from concrete or stone masonry and designed to hold back water by using only the weight of the material and its resistance against the foundation to oppose the horizontal pressure of water pushing against it. Gravity dams are designed so that each section of the dam is stable and independent of any other dam section. Characteristics Gravity dams generally require stiff rock foundations of high bearing strength (slightly weathered to fresh), although in rare cases, they have been built on soil foundations. The bearing strength of the foundation limits the allowable position of the resultant force, influencing the overall stability. Also, the stiff nature of the gravity dam structure is unforgiving to differential foundation settlement, which can induce cracking of the dam structure. Gravity dams provide some advantages over embankment dams, the main advantage being that they can tolerate minor over-topping flows without damage, as the concre ...

The Wirral Peninsula
Wirral (; ), known locally as The Wirral, is a peninsula in North West England. The roughly rectangular peninsula is about long and wide and is bounded by the River Dee to the west (forming the boundary with Wales), the River Mersey to the east, and the Irish Sea to the north. Historically, the Wirral was wholly in Cheshire; in the Domesday Book, its border with the rest of the county was placed at "two arrow falls from Chester city walls". However, since the Local Government Act 1972, only the southern third has been in Cheshire, with almost all the rest lying in the Metropolitan Borough of Wirral, Merseyside. An area of saltmarsh to the south-west of the peninsula lies in the Welsh county of Flintshire. The most extensive urban development is on the eastern side of the peninsula. The Wirral contains both affluent and deprived areas, with affluent areas largely in the west, south and north of the peninsula, and deprived areas concentrated in the east, especially Bir ...

Dee Regulation Scheme
The Dee regulation scheme is a system of flow balancing and quality management along the River Dee managed by a consortium of the three largest water companies licensed to take water from the river, United Utilities, Welsh Water and Severn Trent Water; together with the regulator, Natural Resources Wales. Water demand The water demands of North West England including Liverpool and the Wirral far exceed the locally available sources of clean water. The River Dee runs mainly in North Wales before flowing through Chester, England, and then returning to Wales in a man-made channel constructed to gain land from the Dee Estuary. The Dee is the largest relatively clean river left near to the North West conurbation and without water from the Dee much of Liverpool would be without water, unless local rivers such as the Mersey were rehabilitated. However, the natural flow of the River Dee during most summers is insufficient to sustain any significant abstractions. To overcome this probl ...
