Ditches
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"/"dyke" ...

Drainage
Drainage is the natural or artificial removal of a surface's water and sub-surface water from an area with excess water. The internal drainage of most agricultural soils can 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 Simple infrastructure such as open drains, pipes, and berms are still common. In modern times, more complex structures involving substantial earthworks and new technologies have been common as well. Geotextiles New storm water drainag ...

Dike (construction)
A levee ( or ), dike (American English), dyke (British English; see spelling differences), embankment, floodbank, or stop bank is an elevated ridge, natural or artificial, alongside the banks of a river, often intended to protect against flooding of the area adjoining the river. It is usually earthen and often runs parallel to the course of a river in its floodplain or along low-lying coastlines. Naturally occurring levees form on river floodplains following flooding. Sediment and alluvium are deposited on the banks and settle, forming a ridge that increases the river channel's capacity. Alternatively, levees can be artificially constructed from fill, designed to regulate water levels. In some circumstances, artificial levees can be environmentally damaging. Ancient civilizations in the Indus Valley, ancient Egypt, Mesopotamia and China all built levees. Today, levees can be found around the world, and failures of levees due to erosion or other causes can be major d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Irrigation
Irrigation (also referred to as watering of plants) is the practice of applying controlled amounts of water to land to help grow crops, landscape plants, and lawns. Irrigation has been a key aspect of agriculture for over 5,000 years and has been developed by many cultures around the world. Irrigation helps to grow crops, maintain landscapes, and revegetation, revegetate disturbed soils in dry areas and during times of below-average rainfall. In addition to these uses, irrigation is also employed to protect crops from frost, suppress weed growth in grain fields, and prevent soil consolidation. It is also used to cool livestock, reduce dust, dispose of sewage, and support mining operations. Drainage, which involves the removal of surface and sub-surface water from a given location, is often studied in conjunction with irrigation. There are several methods of irrigation that differ in how water is supplied to plants. Surface irrigation, also known as gravity irrigation, is the olde ...

Farmland (farming)
Arable land (from the , "able to be ploughed") is any land capable of being ploughed and used to grow crops.''Oxford English Dictionary'', "arable, ''adj''. and ''n.''" Oxford University Press (Oxford), 2013. Alternatively, for the purposes of agricultural statistics, the term often has a more precise definition: A more concise definition appearing in the Eurostat glossary similarly refers to actual rather than potential uses: "land worked (ploughed or tilled) regularly, generally under a system of crop rotation". In Britain, arable land has traditionally been contrasted with pasturable land such as heaths, which could be used for sheep-rearing but not as farmland. Arable land is vulnerable to land degradation and some types of un-arable land can be enriched to create useful land. Climate change and biodiversity loss are driving pressure on arable land. By country According to the Food and Agriculture Organization of the United Nations, in 2013, the world's arable land amou ...

The Fens
The Fens or Fenlands in eastern England are a naturally marshy region supporting a rich ecology and numerous species. Most of the fens were drained centuries ago, resulting in a flat, dry, low-lying agricultural region supported by a system of drainage channels and man-made rivers (Ditch, dykes and drains) and automated pumping stations. There have been unintended consequences to this reclamation, as the land level has continued to sink and the dykes have been built higher to protect it from flooding. ''Fen'' is the local term for an individual area of marshland or former marshland. It also designates the type of marsh typical of the area, which has pH, neutral or alkaline water and relatively large quantities of dissolved minerals, but few other plant nutrition, plant nutrients. The Fens are a National Character Area, based on their landscape, biodiversity, geodiversity and economic activity. The Fens lie inland of the Wash, and are an area of nearly in the south east of L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agriculture
Agriculture encompasses crop and livestock production, aquaculture, and forestry for food and non-food products. Agriculture was a key factor in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in the cities. While humans started gathering grains at least 105,000 years ago, nascent farmers only began planting them around 11,500 years ago. Sheep, goats, pigs, and cattle were domesticated around 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. In the 20th century, industrial agriculture based on large-scale monocultures came to dominate agricultural output. , small farms produce about one-third of the world's food, but large farms are prevalent. The largest 1% of farms in the world are greater than and operate more than 70% of the world's farmland. Nearly 40% of agricultural land is found on farms larger than . However, five of every six farm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River Glen, Lincolnshire
The River Glen is a river in Lincolnshire, England with a short stretch passing through Rutland near Essendine. The river's name appears to derive from a Brythonic Celtic language but there is a strong early English connection. Naming In the language of the Ancient Britons, which survives today as Welsh, Cornish and Breton, the neighbouring rivers, the Glen and the Welland seem to have been given contrasting names. The Welland flowed from the area underlain by the Northampton Sands which in many places are bound together by iron oxide to form ironstone. In the Roman period, the sands were easily worked as arable land and the ironstone was dug for smelting. In both cases, the ground was exposed to erosion which meant that silt was carried down to The Fens by the river. In modern Welsh, ''gwaelod'' (from Late Proto-British ''*Woelǫd-'') means bottom and its plural, ''gwaelodion'' means sediment. Among the medieval forms of the name 'Welland' is Weolod; the river could hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Catchwater Drain
A catchwater drain is a land drain, a ditch cut across the fall of the land, typically just above the level of low-lying, level ground such as The Fens of eastern England, where some land, tens of kilometres from the sea is at about sea level. Its purpose is to gather water draining from the higher, sloping ground before it reaches the flat land whence it would be difficult or expensive to remove. The water may be on the surface, in streams or in the ground before it is gathered, perhaps to be led away across the lowland by an embanked river. There are other circumstances in which a catchwater may be employed. A hill-top or hillside may be used to trap rainwater which is then gathered by the catchwater and fed to a reservoir. From this a house, village or town may be supplied. Catchwater may be used to slow down runoff before running on impervious surfaces to reduce runoff.

Soak Dike
The term Soak dike is used in The Fens of eastern England to mean a ditch or drain running parallel with an embankment, for the purpose of taking any water that soaks through from the river or drain beyond the bank. In Lincolnshire, sock dyke was formerly a frequently found form of the expression. In some parts of the world, the embankment would be called a levee. The soak is the ground water in the peat or silt of the fenland, though the term is often used to mean water table. In The Fens, water from the surrounding higher land is carried across the land which lies below high tide level, in embanked rivers. In this way, the need for pumping is reduced. However, the banks are never completely waterproof so that even in an otherwise thoroughly drained fen A fen is a type of peat-accumulating wetland fed by mineral-rich ground or surface water. It is one of the main types of wetland along with marshes, swamps, and bogs. Bogs and fens, both peat-forming ecosystems, ar ...

World
The world is the totality of entities, the whole of reality, or everything that Existence, exists. The nature of the world has been conceptualized differently in different fields. Some conceptions see the world as unique, while others talk of a "plurality of worlds". Some treat the world as #Monism and pluralism, one simple object, while others analyze the world as a complex made up of parts. In #Scientific cosmology, scientific cosmology, the world or universe is commonly defined as "the totality of all space and time; all that is, has been, and will be". #Theories of modality, Theories of modality talk of possible worlds as complete and consistent ways how things could have been. #Phenomenology, Phenomenology, starting from the horizon of co-given objects present in the periphery of every experience, defines the world as the biggest horizon, or the "horizon of all horizons". In #Philosophy of mind, philosophy of mind, the world is contrasted with the mind as that which is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
