River Moyola
The River Moyola or Moyola River stretches for approximately 27 miles from the Sperrin Mountains to Lough Neagh. The Moyola starts a small river (3-5 metres; 10' to 16') for the first few miles of its length and proceeds to expand to a medium-sized river (5-20 metres; 16' to 65') and then to a large river (20 metres +; 65' plus) for its last couple of miles before Lough Neagh. In ancient times, the River Moyola was known as the 'Bior', and served as the border between the Airgiallan kingdoms of Fir Li and Ui Tuirtri. According to Deirdre and Laurence Flanagan in their book, ''Irish Place Names'', the River Moyola derives its name from ''Magh nÉola'', meaning ''Éolas Plain''.Deirdre & Laurence Flanagan, ''Irish Place Names''; Hydrology The flow or discharge of the river is measured near to its mouth in Lough Neagh. The catchment area to the gauging station is , which yields an average flow of . The maximum recorded flow between 1971 and 2012 was on 19 January 1988. The ...

Castledawson
Castledawson is a village in County Londonderry, Northern Ireland. It is mostly within the townland of Shanemullagh (, IPA: anˠˈʃanˠˌwʊl̪ˠəx, about four miles from the north-western shore of Lough Neagh, and near the market town of Magherafelt. At the 2011 Census it had a population of 3,293. History The village sits on the River Moyola and was originally called "Dawson's Bridge". The bridge that crossed the river here was once the largest single span stone bridge in Ireland. The village was named after its 'castle' (actually a large manor house) built by Joshua Dawson in 1713. He was Chief Secretary for Ireland and founded the village in 1710. The Dawson estate, Shanemullagh, shares its name with the original townland name. The Dawson family also founded Christ Church, on the edge of that estate, in the early 18th century. On 29 June 1912, a large group of Ancient Order of Hibernians members, allegedly drunk after having held a parade, clashed with a party of Presb ...

Sperrin Mountains
The Sperrins or Sperrin Mountains () are a range of mountains in Northern Ireland and one of the largest upland areas in Northern Ireland. The range stretches from Strabane eastwards to Slieve Gallion in Desertmartin and north towards Limavady, in the counties of Tyrone and Londonderry. The region has a population of some 150,000 and is a designated Area of Outstanding Natural Beauty. Features It has a distinctive glaciated landscape. The Glenshane Pass, part of the A6 Belfast to Derry road, is in the mountains and has notoriously bad weather in winter. Sawel Mountain is the highest peak in the Sperrins, and the seventh highest in Northern Ireland. Its summit rises to . Another of the Sperrins, Carntogher (464 m), towers over the Glenshane Pass. Geologically, the Sperrins are formed mostly from Precambrian metamorphic rocks, with some younger Ordovician igneous rocks in the southern flank of the range. The Mountains are very sparsely populated and provide habitat for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lough Neagh
Lough Neagh ( ) is a freshwater lake in Northern Ireland and is the largest lake in the island of Ireland, the United Kingdom and the British Isles. It has a surface area of and supplies 40% of Northern Ireland's water. Its main inflows come from the Upper River Bann and River Blackwater, and its main outflow is the Lower River Bann. Its name comes from Irish , meaning " Eachaidh's lake".Deirdre Flanagan and Laurance Flanagan, Irish Placenames, (Gill & Macmillan Ltd, 1994) The lough is owned by the Earl of Shaftesbury and managed by Lough Neagh Partnership Ltd. Geography With an area of , it is the British Isles' largest lake by area and is ranked 33rd in the list of largest lakes of Europe. Located west of Belfast, it is about long and wide. It is very shallow around the margins and the average depth in the main body of the lake is about , although at its deepest the lough is about deep.

Northern Ireland
Northern Ireland ( ga, Tuaisceart Éireann ; sco, label= Ulster-Scots, Norlin Airlann) is a part of the United Kingdom, situated in the north-east of the island of Ireland, that is variously described as a country, province or region. Northern Ireland shares an open border to the south and west with the Republic of Ireland. In 2021, its population was 1,903,100, making up about 27% of Ireland's population and about 3% of the UK's population. The Northern Ireland Assembly (colloquially referred to as Stormont after its location), established by the Northern Ireland Act 1998, holds responsibility for a range of devolved policy matters, while other areas are reserved for the UK Government. Northern Ireland cooperates with the Republic of Ireland in several areas. Northern Ireland was created in May 1921, when Ireland was partitioned by the Government of Ireland Act 1920, creating a devolved government for the six northeastern counties. As was intended, Northern Ireland ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gauging Station
A stream gauge, streamgage or stream gauging station is a location used by hydrologists or environmental scientists to monitor and test terrestrial bodies of water. Hydrometric measurements of water level surface elevation ("stage") and/or volumetric discharge (flow) are generally taken and observations of biota and water quality may also be made. The locations of gauging stations are often found on topographical maps. Some gauging stations are highly automated and may include telemetry capability transmitted to a central data logging facility. Measurement equipment Automated direct measurement of streamflow discharge is difficult at present. In place of the direct measurement of streamflow discharge, one or more surrogate measurements can be used to produce discharge values. In the majority of cases, a stage (the elevation of the water surface) measurement is used as the surrogate. Low gradient (or shallow-sloped) streams are highly influenced by variable downstream c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Till
image:Geschiebemergel.JPG, Closeup of glacial till. Note that the larger grains (pebbles and gravel) in the till are completely surrounded by the matrix of finer material (silt and sand), and this characteristic, known as ''matrix support'', is diagnostic of till. image:Glacial till exposed in roadcut-750px.jpg, Glacial till with tufts of grass Till or glacial till is unsorted glacier, glacial sediment. Till is derived from the erosion and entrainment of material by the moving ice of a glacier. It is deposited some distance down-ice to form terminal, lateral, medial and ground moraines. Till is classified into primary deposits, laid down directly by glaciers, and secondary deposits, reworked by fluvial transport and other processes. Description Till is a form of '' glacial drift'', which is rock material transported by a glacier and deposited directly from the ice or from running water emerging from the ice. It is distinguished from other forms of drift in that it is depos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sand
Sand is a granular material composed of finely divided mineral particles. Sand has various compositions but is defined by its grain size. Sand grains are smaller than gravel and coarser than silt. Sand can also refer to a textural class of soil or soil type; i.e., a soil containing more than 85 percent sand-sized particles by mass. The composition of sand varies, depending on the local rock sources and conditions, but the most common constituent of sand in inland continental settings and non-tropical coastal settings is silica (silicon dioxide, or SiO2), usually in the form of quartz. Calcium carbonate is the second most common type of sand, for example, aragonite, which has mostly been created, over the past 500million years, by various forms of life, like coral and shellfish. For example, it is the primary form of sand apparent in areas where reefs have dominated the ecosystem for millions of years like the Caribbean. Somewhat more rarely, sand may be composed of calciu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aggregate (geology)
In the Earth sciences, aggregate has three possible meanings. In mineralogy and petrology, an aggregate is a mass of mineral crystals, mineraloid particles or rock particles. Examples are dolomite, which is an aggregate of crystals of the mineral dolomite, and ''rock gypsum'', an aggregate of crystals of the mineral gypsum. Lapis lazuli is a type of rock composed of an aggregate of crystals of many minerals including lazurite, pyrite, phlogopite, calcite, potassium feldspar, wollastonite and some sodalite group minerals. In the construction industry, an aggregate (often referred to as a construction aggregate) is sand, gravel or crushed rock that has been mined or quarried for use as a building material. In pedology, an aggregate is a mass of soil particles. If the aggregate has formed naturally, it can be called a ped; if formed artificially, it can be called a clod.

Magherafelt
Magherafelt (, mˠaxəɾʲəˈfʲiːlt̪ˠə is a small town and civil parish in County Londonderry, Northern Ireland. It had a population of 8,805 at the 2011 Census. It is the biggest town in the south of the county and is the social, economic and political hub of the area. It is part of Mid-Ulster District. History Magherafelt has been documented as a town since 1425. An earlier name for the area was ''Teach Fíolta'' - ‘Fíolta’s (monastic) house’. This would suggest that there was a monastic settlement here under the leadership of Fíolta. The site of the medieval parish church may be marked by the ruins of a later church and graveyard at the bottom of Broad Street. The Salters Company of London was granted the surrounding lands in South Londonderry in the seventeenth century as part of the Plantation of Ulster. Subsequently, the town began to take on its current shape with a central diamond forming the heart of the town. During The Troubles in the late 20th c ...
