Rhyne
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 term used in parts of England and Wales for a drainage ditch, or canal, used to turn areas of wetland close to sea level into useful pasture. Water levels (and hence the level of the water table) will usually be controlled by a system of sluice gates and pumps, allowing the land to become wetter at times of the year when this will improve grass growth. Rhynes represent an early method of swamp or marsh drainage. Large sections of swampland were surrounded by trenches deep enough to drain the water from the encircled mound and leave the land relatively dry. Regular clearing and dredging is necessary to keep the rhynes clear of debris so that they flow freely. Rhynes have been used extensively in the United Kingdom, especially on marshy coastal areas such as the Somerset Levels, and the North Somerset Leve ...

Somerset Levels
The Somerset Levels are a coastal plain and wetland area of Somerset, England, running south from the Mendips to the Blackdown Hills. The Somerset Levels have an area of about and are bisected by the Polden Hills; the areas to the south are drained by the River Parrett, and the areas to the north by the rivers Axe and Brue. The Mendip Hills separate the Somerset Levels from the North Somerset Levels. The Somerset Levels consist of marine clay "levels" along the coast and inland peat-based "moors"; agriculturally, about 70 per cent is used as grassland and the rest is arable. Willow and teazel are grown commercially and peat is extracted. A Palaeolithic flint tool found in West Sedgemoor is the earliest indication of human presence in the area. The Neolithic people exploited the reed swamps for their natural resources and started to construct wooden trackways, including the world's oldest known timber trackway, the Post Track, dating from about 3800 BC. The Levels w ... [...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 . 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 extremely rich archaeologically, with finds from the Mesolithic, Bronze Ag ...

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 critic ...

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 and the ...

Drainage Canals
Drainage is the natural or artificial removal of a surface's water and sub-surface water from an area with excess of water. The internal drainage of most agricultural soils is good enough to prevent severe waterlogging (anaerobic conditions that harm root growth), but many soils need artificial drainage to improve production or to manage water supplies. History Early history The Indus Valley civilization had sewerage and drainage systems. All houses in the major cities of Harappa and Mohenjo-daro had access to water and drainage facilities. Waste water was directed to covered gravity sewers, which lined the major streets. 18th and 19th century The invention of hollow-pipe drainage is credited to Sir Hugh Dalrymple, who died in 1753. Current practices Geotextiles New storm water drainage systems incorporate geotextile filters that retain and prevent fine grains of soil from passing into and clogging the drain. Geotextiles are synthetic textile fabrics specially ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water Supply And Sanitation In England And Wales
Public water supply and sanitation in England and Wales has been characterised by universal access and generally good service quality. Salient features of the sector in the United Kingdom compared to other developed countries is the full privatisation of service provision and the pioneering of independent economic regulation in the sector in Europe. There has been a substantial increase in real tariffs between 1989 and 2005, whilst independent assessments place the cost of water provision in the UK as higher than most major countries in the EU. The government body responsible for water regulation, together with the water companies, have claimed improvements in service quality during the same period. Water resources and uses On average, only about 10 percent of freshwater resources in England and Wales are abstracted. Water companies abstract almost half of this amount. The remainder is used for cooling power plants, other industries, fish farming and other uses. Water compa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ditch
A ditch is a small to moderate divot 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"/"dyke" and ...

Wembdon
Wembdon is a semi-rural village near Bridgwater, 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 setting an annual p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. 97% of the water on the Earth is salt water and only three percent is fresh water; slightly over two thirds of this is frozen in glaciers and 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 frozen water. Artificial sources of fresh water can include treated wastewater ( wastewater reuse) and desalinated seawater. Human uses of water resources include agricultural, industrial, household, recreational and environmental activities. Water resources are under threat from water scarcity, water pollution, water conflict and climate change. Fresh water is a renewable resource, yet the world's supply of groundwater is steadily decreasing, with depletio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
