Llyn Celyn
Llyn Celyn () is a reservoir constructed between 1960 and 1965 including the highly controversial Tryweryn flooding in the valley of the River Afon Tryweryn, Tryweryn in Gwynedd, Wales. This included the forcible removal of the Capel Celyn village residents despite protest and opposition of Welsh MPs. With an area of , 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 Culture of Wales, Welsh culture and the Welsh language, whilst the reservoir w ...

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. 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. Stability of the dam primarily arises from the range of normal force angles viably generated by the foundation. Also, the stiff nature of a gravity dam structure endures differential foundation settlement poorly, as it can crack the dam structure. The main advantage to gravity dams over embankments is the scour-resistance of concrete, which protects against damage from minor over-topping flows. Unexpected large over-topping flows are still a problem, as they can scour dam foundations. A disadvantage of gra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Wirral Peninsula
The Wirral Peninsula (), 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 Dee Estuary to the west, the Mersey Estuary to the east, and Liverpool Bay to the north.

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 and reclaimed land adjoining the south-west of the peninsula lies in the Wales, Welsh county of Flintshire. Toponymy The name Wirral literally means "bog myrtle, myrtle corner", from the Old English , a myrtle tree, and , an angle, corner or slope. It is supposed that the land was once overgrown with bog myrtle, a plant no longer found in the area, but plentiful ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dee Regulation Scheme
The Dee regulation scheme is a system of flow balancing and quality management along the River Dee, Wales, 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 Peninsula, the Wirral far exceed the locally available sources of clean water. The River Dee, Wales, 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 sust ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River Dee, Wales
The River Dee (, ) flows through North Wales and Cheshire, England. The majority of the river is located in Wales, with the stretch between Aldford and Saltney within England and two other sections forming the border between the two countries. The length of the section from Bala to Chester is . The river rises on Dduallt in Snowdonia and flows east through Bala Lake, Corwen, and Llangollen. It turns north near Overton-on-Dee and forms part of the England–Wales border before fully entering England near Aldford, north-east of Wrexham. It flows through Chester then re-enters Wales near Saltney; the final section is canalised and discharges to the Irish Sea via an estuary long. History The River Dee was the traditional boundary of the Kingdom of Gwynedd in Wales for centuries, possibly since its founding in the 5th century.

Tryweryn Memorial Chapel W
Afon Tryweryn is a river in the north of Wales which starts at Llyn Tryweryn in the Snowdonia National Park and after joins the river Dee at Bala. One of the main tributaries of the Dee, it was dammed in 1965 to form Llyn Celyn. The Tryweryn flooding forcibly removed residents of the village of Capel Celyn despite popular and political opposition in Wales. The resulting graffiti "Cofiwch Dryweryn" ("Remember Tryweryn") near Llanrhystud became and remains a popular icon of Welsh feeling. Water is stored in Llyn Celyn in winter when flows are high, and released over the summer to maintain the flow in the Dee (water from the Dee is used as the water supply for large areas of north-east Wales, and for the Wirral and much of Liverpool in England). Whitewater sports Afon Tryweryn joins the River Dee roughly half a mile downstream from Bala Lake. The reservoir now at the head of Afon Tryweryn was created in 1965, to provide water to Liverpool. At that time, the 67 inhabitants of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archaic pronoun ''thee'') ...
