River Drone
The River Drone is a river which flows south from its source on the Sheffield, South Yorkshire, border. It flows through Dronfield, Unstone and Unstone Green in Derbyshire before merging at Sheepbridge to the north of Chesterfield with the Barlow Brook. Below the junction, it is often referred to as the River Whitting. It then flows south-east till it merges with the River Rother at Brimington Road North ( B6050) at Chesterfield. It is one of the three main tributaries of the Rother. Course The River Drone rises as several small streams south of Sheffield. One rises close to the contour near the Hamlet of Mickley and flows east, crossing the Midland Main Line railway by an aqueduct a little south of Bradway Tunnel and then passing under the A61 road Unstone-Dronfield Bypass and the B6057 Sheffield Road, which was downgraded when the bypass was constructed. A second source rises north-east of Bradley Tunnel, on Dore and Totley golf course. It flows east and passes under the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River Rother, South Yorkshire
The River Rother, a waterway in the northern midlands of England, gives its name to the town of Rotherham and to the Rother Valley parliamentary constituency. It rises near Clay Cross in Derbyshire and flows in a generally northwards direction through the centre of Chesterfield, where it feeds the Chesterfield Canal, and on through the Rother Valley Country Park and several districts of Sheffield before joining the River Don at Rotherham in Yorkshire. Historically, it powered mills, mainly corn or flour mills, but most had ceased to operate by the early 20th century, and few of the mill buildings survive. From the 1880s, the water quality deteriorated rapidly, as a result of coal mining and its associated communities. The river became unable to sustain life, and by 1974, was the most polluted of the rivers within the River Don catchment. The pollutants came from coking plants, from inefficient sewage treatment plants, and from the manufacture of chemicals. Major investment in ...

Grade II Listed
In the United Kingdom, a listed building or listed structure is one that has been placed on one of the four statutory lists maintained by Historic England in England, Historic Environment Scotland in Scotland, in Wales, and the Northern Ireland Environment Agency in Northern Ireland. The term has also been used in the Republic of Ireland, where buildings are protected under the Planning and Development Act 2000. The statutory term in Ireland is " protected structure". A listed building may not be demolished, extended, or altered without special permission from the local planning authority, which typically consults the relevant central government agency, particularly for significant alterations to the more notable listed buildings. In England and Wales, a national amenity society must be notified of any work to a listed building which involves any element of demolition. Exemption from secular listed building control is provided for some buildings in current use for worship, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Invertebrate
Invertebrates are a paraphyletic group of animals that neither possess nor develop a vertebral column (commonly known as a ''backbone'' or ''spine''), derived from the notochord. This is a grouping including all animals apart from the chordate subphylum Vertebrata. Familiar examples of invertebrates include arthropods, mollusks, annelids, echinoderms and cnidarians. The majority of animal species are invertebrates; one estimate puts the figure at 97%. Many invertebrate taxa have a greater number and variety of species than the entire subphylum of Vertebrata. Invertebrates vary widely in size, from 50 μm (0.002 in) rotifers to the 9–10 m (30–33 ft) colossal squid. Some so-called invertebrates, such as the Tunicata and Cephalochordata, are more closely related to vertebrates than to other invertebrates. This makes the invertebrates paraphyletic, so the term has little meaning in taxonomy. Etymology The word "invertebrate" comes from the Latin word ''vertebra'', whi ...

Environment Agency
The Environment Agency (EA) is a non-departmental public body, established in 1996 and sponsored by the United Kingdom government's Department for Environment, Food and Rural Affairs, with responsibilities relating to the protection and enhancement of the environment in England (and until 2013 also Wales). Based in Bristol, the Environment Agency is responsible for flood management, regulating land and water pollution, and conservation. Roles and responsibilities Purpose The Environment Agency's stated purpose is, "to protect or enhance the environment, taken as a whole" so as to promote "the objective of achieving sustainable development" (taken from the Environment Act 1995, section 4). Protection of the environment relates to threats such as flood and pollution. The vision of the agency is of "a rich, healthy and diverse environment for present and future generations". Scope The Environment Agency's remit covers almost the whole of England, about 13 million h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Act Of Parliament
Acts of Parliament, sometimes referred to as primary legislation, are texts of law passed by the Legislature, legislative body of a jurisdiction (often a parliament or council). In most countries with a parliamentary system of government, acts of parliament begin as a Bill (law), bill, which the legislature votes on. Depending on the structure of government, this text may then be subject to assent or approval from the Executive (government), executive branch. Bills A draft act of parliament is known as a Bill (proposed law), bill. In other words, a bill is a proposed law that needs to be discussed in the parliament before it can become a law. In territories with a Westminster system, most bills that have any possibility of becoming law are introduced into parliament by the government. This will usually happen following the publication of a "white paper", setting out the issues and the way in which the proposed new law is intended to deal with them. A bill may also be introduced in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unstone Railway Station
Unstone railway station was a station in Derbyshire, England. It was built by the Midland Railway in 1870 and was designed by the company architect John Holloway Sanders. It was on what is known to railwaymen as the "New Road" to Sheffield. This bypassed the North Midland Railway's original line, which had avoided Sheffield due to the gradients involved, and came to be known as the "Old Road".Pixton, B., (2000) ''North Midland: Portrait of a Famous Route,'' Cheltenham: Runpast Publishing Originally called Unston, until 1908 when the "e" was added. It had timber buildings without canopies. It closed to passengers in 1951 and for goods services in 1961. From Unstone, the line continued the long 1 in 100 climb to Dronfield Dronfield is a town in North East Derbyshire, England, which includes Dronfield Woodhouse and Coal Aston. It lies in the valley of the River Drone between Chesterfield and Sheffield. The Peak District National Park is to the west. The nam .... ...

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] |
Drainage Basin
A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the '' drainage divide'', made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, "watershed" is used only in its original sense, that of a drainage divide. In a closed drainage basin, or endorheic basin, the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, a dry lake, or a point where surface water is lost underground. Drainage basins are similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weir
A weir or low head dam is a barrier across the width of a river that alters the flow characteristics of water and usually results in a change in the height of the river level. Weirs are also used to control the flow of water for outlets of lakes, ponds, and reservoirs. There are many weir designs, but commonly water flows freely over the top of the weir crest before cascading down to a lower level. Etymology There is no single definition as to what constitutes a weir and one English dictionary simply defines a weir as a small dam, likely originating from Middle English ''were'', Old English ''wer'', derivative of root of ''werian,'' meaning "to defend, dam". Function Commonly, weirs are used to prevent flooding, measure water discharge, and help render rivers more navigable by boat. In some locations, the terms dam and weir are synonymous, but normally there is a clear distinction made between the structures. Usually, a dam is designed specifically to impound water behind ...

Brown Trout
The brown trout (''Salmo trutta'') is a European species of salmonid fish that has been widely introduced into suitable environments globally. It includes purely freshwater populations, referred to as the riverine ecotype, ''Salmo trutta'' morpha ''fario'', a lacustrine ecotype, ''S. trutta'' morpha ''lacustris'', also called the lake trout, and anadromous forms known as the sea trout, ''S. trutta'' morpha ''trutta''. The latter migrates to the oceans for much of its life and returns to fresh water only to spawn. Sea trout in Ireland and Britain have many regional names: sewin in Wales, finnock in Scotland, peal in the West Country, mort in North West England, and white trout in Ireland. The lacustrine morph of brown trout is most usually potamodromous, migrating from lakes into rivers or streams to spawn, although evidence indicates some stocks spawn on wind-swept shorelines of lakes. ''S. trutta'' morpha ''fario'' forms stream-resident populations, typically in alpine stre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water Wheel
A water wheel is a machine for converting the energy of flowing or falling water into useful forms of power, often in a watermill. A water wheel consists of a wheel (usually constructed from wood or metal), with a number of blades or buckets arranged on the outside rim forming the driving car. Water wheels were still in commercial use well into the 20th century but they are no longer in common use. Uses included milling flour in gristmills, grinding wood into pulp for papermaking, hammering wrought iron, machining, ore crushing and pounding fibre for use in the manufacture of cloth. Some water wheels are fed by water from a mill pond, which is formed when a flowing stream is dammed. A channel for the water flowing to or from a water wheel is called a mill race. The race bringing water from the mill pond to the water wheel is a headrace; the one carrying water after it has left the wheel is commonly referred to as a tailrace. Waterwheels were used for various purposes from ag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
