Reen Infrastructure
A rhyne (Somerset), rhine/rhyne (Gloucestershire), or reen (South Wales) (all pronounced "reen"; from Old English ''ryne'' or Welsh ''rhewyn'' or ''rhewin'' "ditch") is a drainage ditch, or canal, used to turn areas of wetland close to sea level into useful pasture. Water levels will usually be controlled by a system of sluice gates and pumps. Rhynes have been used extensively in the United Kingdom. Etymology The spelling of the term varies, though all terms are pronounced , which comes from terms for ''ditch'' in Old English (''ryne'') or Welsh (''rhewyn'' or ''rhewin''). The term is ''rhyne'' in Somerset, ''rhine'' or ''rhyne'' in Gloucestershire, and ''reen'' in South Wales. The etymology of the name is unclear. Some sources claim that rhyne is derived from the Irish word ''rathin'', a diminutive of ''rath'' —a circular mound or entrenchment. The word ''rhewyn'' is attested in Welsh from the 1400s onwards.

North Somerset Levels
The North Somerset Levels is a coastal plain, an expanse of low-lying flat ground, which occupies an area between Weston-super-Mare and Bristol in North Somerset, England. The River Banwell, River Kenn, River Yeo and Land Yeo are the three principal rivers draining the area. To the south the levels are bounded by the Mendip Hills, to the east by the Yeo Valley and the Lulsgate Plateau, and to the north by the Tickenham Ridge. To the west lies the Severn Estuary. The levels are distinct from two similar areas: the much larger Somerset Levels to the south in Somerset, and the smaller Gordano Valley to the north. The water level management and maintenance of rhynes in the area are the responsibility of the North Somerset Internal Drainage Board. The term "Avon Levels" has also been used - either as a synonym for the North Somerset Levels, or to refer a larger area also including all of the other low-lying flat areas in the former county of Avon (e.g. the Gordano Valley an ...

Ditch
A ditch is a small to moderate trench created to channel water. A ditch can be used for drainage, to drain water from low-lying areas, alongside roadways or fields, or to channel water from a more distant source for plant irrigation. Ditches are commonly seen around farmland, especially in areas that have required drainage, such as The Fens in eastern England and much of the Netherlands. Roadside ditches may provide a hazard to motorists and cyclists, whose vehicles may crash into them and get damaged, flipped over, or stuck and cause major injury, especially in poor weather conditions and rural areas. Etymology In Anglo-Saxon, the word ''dïc'' already existed and was pronounced ("deek") in northern England and "deetch" in the south. The origins of the word lie in digging a trench and forming the upcast soil into a bank alongside it. This practice has meant that the name ''dïc'' was given to either the excavation or the bank, and evolved to both the words "dike"/" ...

Canal
Canals or artificial waterways are waterways or engineered channels built for drainage management (e.g. flood control and irrigation) or for conveyancing water transport vehicles (e.g. water taxi). They carry free, calm surface flow under atmospheric pressure, and can be thought of as artificial rivers. In most cases, a canal has a series of dams and locks that create reservoirs of low speed current flow. These reservoirs are referred to as ''slack water levels'', often just called ''levels''. A canal can be called a navigation canal when it parallels a natural river and shares part of the latter's discharges and drainage basin, and leverages its resources by building dams and locks to increase and lengthen its stretches of slack water levels while staying in its valley. A canal can cut across a drainage divide atop a ridge, generally requiring an external water source above the highest elevation. The best-known example of such a canal is the Panama Can ...

Wembdon
Wembdon is a semi-rural area of Bridgwater on the town’s outskirts, in Somerset, England. Wembdon is now home to an Anglican church, a small shop (combined with the post office), a pub and a small garage. History Wembdon was listed in the Domesday Book of 1086 as having "5 villagers and 6 smallholders with four ploughs". The name Wembdon is believed to mean "Huntsman's Hill", referring to Wembdon Hill itself where Saxon* burials have been discovered. These are believed to be British burials which date to the Saxon period. Wembdon Hill is also the site of St. Johns Well, which was renowned for its healing powers from the 15th century onwards. In 2002 a northern distributor road for Bridgwater was built to the south of the village to ease traffic congestion in Bridgwater town centre. The road had been part of local town planning since the 1980s, and building proceeded despite some local resistance. Governance The parish council has responsibility for local issues, including s ...

Internal Drainage Board
An internal drainage board (IDB) is a type of operating authority which is established in areas of special drainage need in England and Wales with permissive powers to undertake work to secure clean water drainage and water level management within drainage districts. The area of an IDB is not determined by county or metropolitan council boundaries, but by water catchment areas within a given region. IDBs are geographically concentrated in the Broads, Fens in East Anglia and Lincolnshire, Somerset Levels and Yorkshire. In comparison with public bodies in other countries, IDBs are most similar to the ''Waterschappen'' of the Netherlands, ''Consorzi di bonifica e irrigazione'' of Italy, '' wateringen'' of Flanders and Northern France, Watershed Districts of Minnesota, United States and Marsh Bodies of Nova Scotia, Canada. Responsibilities Much of their work involves the maintenance of rivers, drainage channels ( rhynes), ordinary watercourses, pumping stations and other cri ...

Water Resource Management
Water resources are natural resources of water that are potentially useful for humans, for example as a source of drinking water supply or irrigation water. These resources can be either Fresh water, freshwater from natural sources, or water produced artificially from other sources, such as from reclaimed water (wastewater) or Desalination, desalinated water (seawater). 97% of the water on Earth is saline water, salt water and only three percent is fresh water; slightly over two-thirds of this is frozen in glaciers and polar climate, polar ice caps. The remaining unfrozen freshwater is found mainly as groundwater, with only a small fraction present above ground or in the air. Natural sources of fresh water include surface water, under river flow, groundwater and ice, frozen water. People use water resources for agriculture, agricultural, Industry (economics), industrial and household activities. Water resources are under threat from multiple issues. There is water scarcity, water p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caldicot And Wentloog Levels
The Caldicot and Wentloog Levels are two areas of low-lying estuarine alluvial wetland and intertidal mudflats adjoining the north bank of the Severn Estuary, either side of the River Usk estuary near Newport in south east Wales. They are also known collectively as the Monmouthshire Levels or Gwent Levels, and the name Wentloog is sometimes spelled Wentlooge in official publications. The Caldicot Level lies to the southeast of Newport between the River Usk and River Wye and consists of . It is home to Newport Wetlands Reserve. The Wentloog Level lies to the southwest between the River Usk and Rhymney River and consists of . They are an agricultural region interspersed with suburban development. The levels are formed from tidal deposits and alluvium, which have been recurrently inundated and reclaimed from the Severn Estuary by humans since Roman times. They have been patterns of settlement, enclosure and drainage systems belonging to successive periods of use, and are extr ...

Aust
Aust is a small village in South Gloucestershire, England, about north of Bristol and about south west of Gloucester. It is located on the eastern side of the Severn estuary, close to the eastern end of the Severn Bridge which carries the M48 motorway. The village has a chapel, a church and a public house. There is a large area of farmland on the river bank, which is sometimes flooded due to the high tidal range of the River Severn, Severn. Aust Cliff, above the Severn, is located about from the village. The civil parish of Aust includes the villages of Elberton, Gloucestershire, Elberton and Littleton-upon-Severn. History Overview Aust, on the River Severn, was at one end of an ancient Roman road that led to Cirencester. Its name, Aust, may be one of the very few English place-names to be derived from the Latin ''Augusta''. "Augustin endeavoured to persuade the Welsh clergy to join him in preaching the Gospel to the Teutonic invaders, and held a meeting with them at or nea ...

Avonmouth
Avonmouth ( ) is a port and outer suburb of Bristol, England, on the north bank of the mouth of the River Avon and the eastern shore of the Severn Estuary. Part of the Port of Bristol, Avonmouth Docks is important to the region's maritime economy, hosting large vessels for the unloading and exporting of heavier goods. Much of the land use is industrial, including warehousing, light industry, electrical power and sanitation. The M5 motorway bisects the neighbourhood, with junctions onto the A4 road and M49 motorway, and it has stations on the Severn Beach Line railway. Avonmouth is part of the Bristol City Council electoral ward of Avonmouth and Lawrence Weston, which also includes Shirehampton and the western end of Lawrence Weston. Geography Avonmouth is approximately rectangular, its length favouring the Severn shore, and sits on the north bank of the Avon, west-north-west of Bristol city centre.

Severn Estuary
The Severn Estuary () is the estuary of the River Severn, flowing into the Bristol Channel between South West England (from North Somerset, Bristol and South Gloucestershire) and South Wales (from Cardiff, Newport to Monmouthshire). Its very high tidal range, approximately , creates valuable intertidal habitats and has led to the area being at the centre of discussions in the UK regarding renewable tidal energy. Geography Definitions of the limits of the Severn Estuary vary. In pre-modern times the area was commonly referred to as the River Severn, or the Severn Sea. Today, at the upstream boundary, the normal tidal limit of the river is at Maisemore weir (on the West Channel) and Llanthony Weir (on the East Channel), close to Gloucester Docks, although exceptionally high tides can overtop these weirs. Downstream, the estuary transitions into the open sea of the Bristol Channel. The distinction between the estuary and the Bristol Channel is ambiguous, with some sources ...

Sharpness Canal
The Gloucester and Sharpness Canal (also known as the Gloucester and Berkeley Canal) is a ship canal in the west of England, between Gloucester and Sharpness, completed in 1827. For much of its length the canal runs close to the tidal River Severn, but it cuts off a significant loop in the river, at a once-dangerous bend near Arlingham. It was once the broadest and deepest canal in the world. The canal is long. Canal planning and construction Conceived in the canal mania period of the late 18th century, the Gloucester and Berkeley Ship Canal scheme (as it was originally named) was started by architect and civil engineer Robert Mylne. In 1793 an act of Parliament, the ( 33 Geo. 3. c. 97) was obtained authorising the raising of a total of £200,000.Hadfield (1969), p.342 The project rapidly encountered financial difficulties, to such an extent that Mylne left the project in 1798. By mid-1799 costs had reached £112,000 but only of the canal had been completed.Hadfield (19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
