River Cober
The River Cober ( kw, Dowr Kohar) is a short river in west Cornwall, England, United Kingdom. The river runs to the west of Helston into The Loe, Cornwall's largest natural lake. Geology and hydrology It rises in Nine Maidens Downs, directly between Hangman's Barrow to the west and the Nine Maidens stone circle to the east, in the former Kerrier District and runs to the west of the town of Helston before entering the largest natural lake in Cornwall – Loe Pool. The water is impounded by the natural barrier, Loe Bar, and the river system can be traced several kilometres out into Mount's Bay. Mining activity of over one hundred years in the river catchment, ceased in 1938, in the Wendron and Porkellis mining districts; and the engine house of Castle Wary (also known as Wheal Pool), near Nansloe can still be seen on the east side of the river below Helston. The lower reaches of river was canalised in 1946 and a causeway built over Loe Marsh in 1987.Le. Messurier, B. and Luck ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United Kingdom
The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a country in Europe, off the north-western coast of the continental mainland. It comprises England, Scotland, Wales and Northern Ireland. The United Kingdom includes the island of Great Britain, the north-eastern part of the island of Ireland, and many smaller islands within the British Isles. Northern Ireland shares a land border with the Republic of Ireland; otherwise, the United Kingdom is surrounded by the Atlantic Ocean, the North Sea, the English Channel, the Celtic Sea and the Irish Sea. The total area of the United Kingdom is , with an estimated 2020 population of more than 67 million people. The United Kingdom has evolved from a series of annexations, unions and separations of constituent countries over several hundred years. The Treaty of Union between the Kingdom of England (which included Wales, annexed in 1542) and the Kingdom of Scotland in 170 ...

Porkellis
Porkellis ( kw, Porthkellys) is a village in Cornwall, England, United Kingdom. It is approximately three and a half miles north-east of Helston, and is in the heart of the old Wendron mining district. The village has a pub (The Star Inn), Methodist chapel, village hall and primary school. The name ''Porkellis'' comes from the Cornish language words ''porth'', meaning 'cove' or 'gate', and ''kellys'', meaning 'lost'. Chapels Porkellis has two chapels, both of which are Grade II listed. The original chapel was built in 1814, whereas the later Wesleyan chapel was bigger and built in 1866 alongside the older one. When the latter chapel was built the original was converted into a schoolroom. Services now take place in the earlier 1814 Chapel, sympathetically refurbished as the 1866 building has been sold and is currently under renovation. The building of a church (dedicated to St Christopher) and intended to seat 120 people started in January 1882, at an estimated cost of £700 an ...

Kaolin
Kaolinite ( ) is a clay mineral, with the chemical composition Al2 Si2 O5( OH)4. It is an important industrial mineral. It is a layered silicate mineral, with one tetrahedral sheet of silica () linked through oxygen atoms to one octahedral sheet of alumina () octahedra. Rocks that are rich in kaolinite are known as kaolin () or china clay. Kaolin is occasionally referred to by the antiquated term lithomarge, from the Ancient Greek ''litho-'' and Latin ''marga'', meaning 'stone of marl'. Presently the name lithomarge can refer to a compacted, massive form of kaolin. The name ''kaolin'' is derived from Gaoling (), a Chinese village near Jingdezhen in southeastern China's Jiangxi Province. The name entered English in 1727 from the French version of the word: , following François Xavier d'Entrecolles's reports on the making of Jingdezhen porcelain. Kaolinite has a low shrink–swell capacity and a low cation-exchange capacity (1–15 meq/100 g). It is a soft, earthy, usu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flint
Flint, occasionally flintstone, is a sedimentary cryptocrystalline form of the mineral quartz, categorized as the variety of chert that occurs in chalk or marly limestone. Flint was widely used historically to make stone tools and start fires. It occurs chiefly as nodules and masses in sedimentary rocks, such as chalks and limestones.''The Flints from Portsdown Hill'' Inside the nodule, flint is usually dark grey, black, green, white or brown in colour, and often has a glassy or waxy appearance. A thin layer on the outside of the nodules is usually different in colour, typically white and rough in texture. The nodules can often be found along s and |
Barrier Beach
Barrier islands are coastal landforms and a type of dune system that are exceptionally flat or lumpy areas of sand that form by wave and tidal action parallel to the mainland coast. They usually occur in chains, consisting of anything from a few islands to more than a dozen. They are subject to change during storms and other action, but absorb energy and protect the coastlines and create areas of protected waters where wetlands may flourish. A barrier chain may extend uninterrupted for over a hundred kilometers, excepting the tidal inlets that separate the islands, the longest and widest being Padre Island of Texas, United States. Sometimes an important inlet may close permanently, transforming an island into a peninsula, thus creating a barrier peninsula, often including a beach, barrier beach. The length and width of barriers and overall morphology of barrier coasts are related to parameters including tidal range, wave energy, sediment supply, sea-level trends, and basemen ...

Sea Level
Mean sea level (MSL, often shortened to sea level) is an average surface level of one or more among Earth's coastal bodies of water from which heights such as elevation may be measured. The global MSL is a type of vertical datuma standardised geodetic datumthat is used, for example, as a chart datum in cartography and marine navigation, or, in aviation, as the standard sea level at which atmospheric pressure is measured to calibrate altitude and, consequently, aircraft flight levels. A common and relatively straightforward mean sea-level standard is instead the midpoint between a mean low and mean high tide at a particular location. Sea levels can be affected by many factors and are known to have varied greatly over geological time scales. Current sea level rise is mainly caused by human-induced climate change. When temperatures rise, Glacier, mountain glaciers and the Ice sheet, polar ice caps melt, increasing the amount of water in water bodies. Because most of human settlem ...

Loe Bar
The Loe ( kw, An Logh), also known as Loe Pool, is the largest natural freshwater lake () in Cornwall, United Kingdom. The earliest recorded appearance of this simple name form was in 1337, when it was called "La Loo", but is mentioned as 'the lake' in 1302; Situated between Porthleven and Gunwalloe and downstream of Helston, it is separated from Mount's Bay by the shingle bank of Loe Bar. Both the Loe (including the southern arm known as Carminowe Creek) and Loe Bar are situated within the Penrose Estate, which is administered by the National Trust, and are designated as a Site of Special Scientific Interest by Natural England. It is within the Cornwall Area of Outstanding Natural Beauty and is considered a classic Geological Conservation Review Site.May, V.J. Loe Bar. In May, V.J. and Hansom, J.D.

Hundreds Of Cornwall
The hundreds of Cornwall ( kw, Keverangow Kernow) were administrative divisions or Shires ( hundreds) into which Cornwall, the present day administrative county of England, in the United Kingdom, was divided between and 1894, when they were replaced with local government districts. Some of the names of the hundreds ended with the suffix ''shire'' as in Pydarshire, East and West Wivelshire and Powdershire which were first recorded as names between 1184 and 1187. In the Cornish language the word ''keverang'' (''pl. keverangow'') is the equivalent for English "hundred" and the Welsh cantref. The word, in its plural form, appears in place names like Meankeverango (i.e. stone of the hundreds) in 1580 (now The Enys, north of Prussia Cove and marking the southern end of the boundary between the hundreds of Penwith and Kerrier), and Assa Govranckowe 1580, Kyver Ankou ''c.'' 1720, also on the Penwith – Kerrier border near Scorrier.

Canalised
River engineering is a discipline of civil engineering which studies human intervention in the course, characteristics, or flow of a river with the intention of producing some defined benefit. People have intervened in the natural course and behaviour of rivers since before recorded history—to manage the water resources, to protect against flooding, or to make passage along or across rivers easier. Since the Yuan Dynasty and Ancient Roman In modern historiography, ancient Rome refers to Roman civilisation from the founding of the city of Rome in the 8th century BC to the collapse of the Western Roman Empire in the 5th century AD. It encompasses the Roman Kingdom (753–509 BC ... times, rivers have been used as a source of hydropower.
