Turlough (lake)
A turlough (turloch or turlach in Irish), is a seasonal or periodic water body found mostly in limestone karst areas of Ireland, west of the River Shannon. The name comes from the Irish ''tur'', meaning "dry", and ''loch'', meaning "lake". The water bodies fill and empty with the changes in the level of the water table, usually being very low or empty during summer and autumn and full in the winter. As groundwater levels drop the water drains away underground through cracks in the karstic limestone. Turloughs are almost unique to Ireland, although there is one example in Wales, Pant-y-Llyn at Cernydd Carmel near Llandeilo. They are of great interest to many scientists: geomorphologists are interested in how turloughs were formed, hydrologists try to explain what makes turloughs flood, botanists study the unusual vegetation which covers the turlough floor, and zoologists study the animals associated with the turloughs. Locations Turloughs are mostly found on the central ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for lime ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
County Clare
County Clare ( ga, Contae an Chláir) is a county in Ireland, in the Southern Region and the province of Munster, bordered on the west by the Atlantic Ocean. Clare County Council is the local authority. The county had a population of 118,817 at the 2016 census. The county town and largest settlement is Ennis. Geography and subdivisions Clare is north-west of the River Shannon covering a total area of . Clare is the seventh largest of Ireland's 32 traditional counties in area and the 19th largest in terms of population. It is bordered by two counties in Munster and one county in Connacht: County Limerick to the south, County Tipperary to the east and County Galway to the north. Clare's nickname is ''the Banner County''. Baronies, parishes and townlands The county is divided into the baronies of Bunratty Lower, Bunratty Upper, Burren, Clonderalaw, Corcomroe, Ibrickan, Inchiquin, Islands, Moyarta, Tulla Lower and Tulla Upper. These in turn are divided into civ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rahasane Turlough
Rahasane turlough is a turlough (an intermittent lake), west of Craughwell in southwest County Galway. It is the largest surviving turlough in Ireland. A turlough is a karst lake, which has no surface outlet and is surrounded on all sides by rising land. At Rahasane the drainage has been modified in that since the nineteenth century the Dunkellin river has followed an artificial channel downstream of the turlough, but part of the flow continues to go underground, via a natural sink, into the underlying limestone. Rahasane consists of two basins which are connected at times of flood but separated as the waters decline. It covers 257 ha at an altitude of 10–30m above sea level. The site comprises marshes, and seasonally flooded wet meadows, with limestone outcrops and scrub at its margins. In the summer the lake empties and the basin is grazed by cattle, horses and sheep. The southern basin is the more impressive feature, with high rocky sides above an undulating base, strewn w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Wales
South Wales ( cy, De Cymru) is a loosely defined region of Wales bordered by England to the east and mid Wales to the north. Generally considered to include the historic counties of Glamorgan and Monmouthshire, south Wales extends westwards to include Carmarthenshire and Pembrokeshire. In the western extent, from Swansea westwards, local people would probably recognise that they lived in both south Wales and west Wales. The Brecon Beacons National Park covers about a third of south Wales, containing Pen y Fan, the highest British mountain south of Cadair Idris in Snowdonia. A point of some discussion is whether the first element of the name should be capitalised: 'south Wales' or 'South Wales'. As the name is a geographical expression rather than a specific area with well-defined borders, style guides such as those of the BBC and ''The Guardian'' use the form 'south Wales'. In a more authoritative style guide, the Welsh Government, in their international gateway w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
