River Purwell
The River Purwell is a chalk stream in Hertfordshire, England. The entire course of the stream is near Hitchin. Its source is springs which rise out of the chalk bedrock at St Ippolyts, forming Ippollitts Brook. It is known as the Purwell by the time it reaches Ninesprings on the border of the parishes of Great Wymondley and Hitchin. It flows on to join the River Hiz. The river and associated wetlands are protected by nature reserves at Ninesprings and Purwell Meadows. Purwell Mill At Purwell Meadows the river powered a watermill until the 1920s. The existing building is a couple of hundred years old, but a mill at this site is mentioned in the Domesday Book Domesday Book () – the Middle English spelling of "Doomsday Book" – is a manuscript record of the "Great Survey" of much of England and parts of Wales completed in 1086 by order of King William I, known as William the Conqueror.

River Purwell In Purwell Meadows 5
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle. Water generally collects in a river from precipitation through a drainage basin from surface runoff and other sources such as groundwater recharge, springs, an ...

Nature Reserve
A nature reserve (also known as a wildlife refuge, wildlife sanctuary, biosphere reserve or bioreserve, natural or nature preserve, or nature conservation area) is a protected area of importance for flora, fauna, or features of geological or other special interest, which is reserved and managed for purposes of conservation and to provide special opportunities for study or research. They may be designated by government institutions in some countries, or by private landowners, such as charities and research institutions. Nature reserves fall into different IUCN categories depending on the level of protection afforded by local laws. Normally it is more strictly protected than a nature park. Various jurisdictions may use other terminology, such as ecological protection area or private protected area in legislation and in official titles of the reserves. History Cultural practices that roughly equate to the establishment and maintenance of reserved areas for animals date bac ...

Penny (British Pre-decimal Coin)
The British pre-decimal penny was a denomination of sterling coinage worth of one pound or of one shilling. Its symbol was ''d'', from the Roman denarius. It was a continuation of the earlier English penny, and in Scotland it had the same monetary value as one pre-1707 Scottish shilling. The penny was originally minted in silver, but from the late 18th century it was minted in copper, and then after 1860 in bronze. The plural of "penny" is "pence" when referring to an amount of money, and "pennies" when referring to a number of coins. Thus 8''d'' is eight pence, but "eight pennies" means specifically eight individual penny coins. Before Decimal Day in 1971, sterling used the Carolingian monetary system (£sd), under which the largest unit was a pound (£) divisible into 20 shillings (s), each of 12 pence (d). The penny was withdrawn in 1971 due to decimalisation, and replaced (in effect) by the decimal half new penny, with p being worth 1.2''d''. History The kingdoms o ...

William The Conqueror
William I; ang, WillelmI (Bates ''William the Conqueror'' p. 33– 9 September 1087), usually known as William the Conqueror and sometimes William the Bastard, was the first House of Normandy, Norman List of English monarchs#House of Normandy, king of England, reigning from 1066 until his death in 1087. A descendant of Rollo, he was Duke of Normandy from 1035 onward. By 1060, following a long struggle to establish his throne, his hold on Normandy was secure. In 1066, following the death of Edward the Confessor, William invaded England, leading an army of Normans to victory over the Anglo-Saxons, Anglo-Saxon forces of Harold Godwinson at the Battle of Hastings, and suppressed subsequent English revolts in what has become known as the Norman Conquest. The rest of his life was marked by struggles to consolidate his hold over England and his continental lands, and by difficulties with his eldest son, Robert Curthose. William was the son of the unmarried Duke Robert I of Normandy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shilling (British Coin)
The British shilling, abbreviated "1/-", was a unit of currency and a denomination of sterling coinage worth of one pound, or twelve pence. It was first minted in the reign of Henry VII as the testoon, and became known as the shilling, from the Old English , sometime in the mid-16th century. It circulated until 1990. The word ''bob'' was sometimes used for a monetary value of several shillings, e.g. "ten-bob note". Following decimalisation on 15 February 1971 the coin had a value of five new pence, and a new coin of the same value but labelled as "five new pence" or "five pence" was minted with the same size as the shilling until 1990, after which the shilling no longer remained legal tender. It was made from silver from its introduction in or around 1503 until 1946, and thereafter in cupronickel. Before Decimal Day in 1971, sterling used the Carolingian monetary system ("£sd"), under which the largest unit was a pound (£) divided into 20 shillings (s), each of 12 pence (d ...

Domesday Book
Domesday Book () – the Middle English spelling of "Doomsday Book" – is a manuscript record of the "Great Survey" of much of England and parts of Wales completed in 1086 by order of King William I, known as William the Conqueror. The manuscript was originally known by the Latin name ''Liber de Wintonia'', meaning "Book of Winchester", where it was originally kept in the royal treasury. The '' Anglo-Saxon Chronicle'' states that in 1085 the king sent his agents to survey every shire in England, to list his holdings and dues owed to him. Written in Medieval Latin, it was highly abbreviated and included some vernacular native terms without Latin equivalents. The survey's main purpose was to record the annual value of every piece of landed property to its lord, and the resources in land, manpower, and livestock from which the value derived. The name "Domesday Book" came into use in the 12th century. Richard FitzNeal wrote in the ''Dialogus de Scaccario'' ( 1179) that the book ...

Watermill
A watermill or water mill is a mill that uses hydropower. It is a structure that uses a water wheel or water turbine to drive a mechanical process such as milling (grinding), rolling, or hammering. Such processes are needed in the production of many material goods, including flour, lumber, paper, textiles, and many metal products. These watermills may comprise gristmills, sawmills, paper mills, textile mills, hammermills, trip hammering mills, rolling mills, wire drawing mills. One major way to classify watermills is by wheel orientation (vertical or horizontal), one powered by a vertical waterwheel through a gear mechanism, and the other equipped with a horizontal waterwheel without such a mechanism. The former type can be further divided, depending on where the water hits the wheel paddles, into undershot, overshot, breastshot and pitchback (backshot or reverse shot) waterwheel mills. Another way to classify water mills is by an essential trait about their location: tide mills ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wetland
A wetland is a distinct ecosystem that is flooded or saturated by water, either permanently (for years or decades) or seasonally (for weeks or months). Flooding results in oxygen-free (anoxic) processes prevailing, especially in the soils. The primary factor that distinguishes wetlands from terrestrial land forms or Body of water, water bodies is the characteristic vegetation of aquatic plants, adapted to the unique anoxic hydric soils. Wetlands are considered among the most biologically diverse of all ecosystems, serving as home to a wide range of plant and animal species. Methods for assessing wetland functions, wetland ecological health, and general wetland condition have been developed for many regions of the world. These methods have contributed to wetland conservation partly by raising public awareness of the functions some wetlands provide. Wetlands occur naturally on every continent. The water in wetlands is either freshwater, brackish or seawater, saltwater. The main w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chalk Stream
Chalk streams are rivers that rise from springs in landscapes with chalk bedrock. Since chalk is permeable, water percolates easily through the ground to the water table and chalk streams therefore receive little surface runoff. As a result, the water in the streams contains little organic matter and sediment and is generally very clear. The beds of the rivers are generally composed of clean, compacted gravel and flints, which are good spawning areas for Salmonidae fish species. Since they are fed primarily by aquifers, the flow rate, mineral content and temperature range of chalk streams exhibit less seasonal variation than other rivers. They are mildly alkaline and contain high levels of nitrate, phosphate, potassium and silicate. In addition to algae and diatoms, the streams provide a suitable habitat for macrophytes (including water crowfoot) and oxygen levels are generally supportive of coarse fish populations. Of the 210 rivers classified as chalk streams globally, 160 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River Hiz
The River Hiz is a small () tributary river in Hertfordshire that feeds the River Ivel that, in turn, feeds the River Great Ouse.
