Chelmer And Blackwater Navigation
The Chelmer and Blackwater Navigation is the canalisation of the Rivers Chelmer and Blackwater in Essex, in the east of England. The navigation runs for from Springfield Basin in Chelmsford to the sea lock at Heybridge Basin near Maldon. Initial plans faced spirited opposition from Maldon, which were overcome by avoiding the town and terminating at Heybridge, and the navigation opened in 1797. There were some teething problems, and the engineer John Rennie was called back on two occasions to recommend improvements. The impact of the railways was less severe than on many canals, as there was never a direct line between Chelmsford and Maldon. The sea lock at Heybridge was enlarged after the Second World War, but trade gradually declined and ceased in 1972. Unlike most canals, it was not nationalised in 1948, and remained under the control of the original company. The first leisure boats to use the navigation did so in 1973, when the Inland Waterways Association organised a ral ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Canal. Many ...

John Smeaton
John Smeaton (8 June 1724 – 28 October 1792) was a British civil engineer responsible for the design of bridges, canals, harbours and lighthouses. He was also a capable mechanical engineer and an eminent physicist. Smeaton was the first self-proclaimed "civil engineer", and is often regarded as the "father of civil engineering".Mark Denny (2007). "Ingenium: Five Machines That Changed the World". p. 34. JHU Press. He pioneered the use of hydraulic lime in concrete, using pebbles and powdered brick as aggregate. Smeaton was associated with the Lunar Society. Law and physics Smeaton was born in Austhorpe, Leeds, England. After studying at Leeds Grammar School he joined his father's law firm, but left to become a mathematical instrument maker (working with Henry Hindley), developing, among other instruments, a pyrometer to study material expansion. In 1750, his premises were in the Great Turnstile in Holborn. He was elected a Fellow of the Royal Society in 1753 and in 1 ...

Witham-Maldon Branch Line
The Witham to Maldon branch line is a closed railway line joining Maldon to the British railway network at Witham in Essex, England. It was opened in 1848 and was long. It was extended to Woodham Ferris (later Woodham Ferrers) to give direct access to Southend-on-Sea, but that extension was not commercially successful. The Woodham Ferrers extension was closed to passenger traffic in 1939 and completely in 1953. The original main line from Maldon to Witham also declined in passenger carryings; efforts to stimulate business included the introduction of low-cost diesel railbuses and a more intensive passenger service. This proved to be in vain and the passenger service was withdrawn in 1964. A residual goods service continued but, from 1980, the line was completely closed. First proposals In 1825, the Stockton and Darlington Railway opened and many communities were prompted to consider whether a railway was a means to increased prosperity locally. A meeting at Maldon in that year c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coal
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous ( Pennsylvanian) and Permian times. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its electricity. Some iron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gasworks
A gasworks or gas house is an industrial plant for the production of flammable gas. Many of these have been made redundant in the developed world by the use of natural gas, though they are still used for storage space. Early gasworks Coal gas was introduced to Great Britain in the 1790s as an illuminating gas by the Scottish inventor William Murdoch. Early gasworks were usually located beside a river or canal so that coal could be brought in by barge. Transport was later shifted to railways and many gasworks had internal railway systems with their own locomotives. Early gasworks were built for factories in the Industrial Revolution from about 1805 as a light source and for industrial processes requiring gas, and for lighting in country houses from about 1845. Country house gas works are extant at Culzean Castle in Scotland and Owlpen in Gloucestershire. Equipment A gasworks was divided into several sections for the production, purification and storage of gas. Retort ho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
James Green (engineer)
James Green (1781–1849) was a noted civil engineer and canal engineer, who was particularly active in the South West of England, where he pioneered the building of tub boat canals, and inventive solutions for coping with hilly terrain, which included tub boat lifts and inclined planes. Although dismissed from two schemes within days of each other, as a result of construction problems, his contribution as a civil engineer was great. Early career James Green was born in Birmingham, the son of an engineering family. He learned much from his father, by whom he was employed until the age of 20. He then worked with John Rennie on a number of projects around the country, until 1808, when he moved to Devon, and established a base at Exeter. He submitted plans for the rebuilding of Fenny Bridges, in East Devon, which had collapsed only 18 months after their previous reconstruction. The plans were accepted, and Green became the Bridge Surveyor for the County of Devon. By 1818 he had ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Little Baddow
Little Baddow is a village to the east of Chelmsford, Essex. The name ''Baddow'' comes from an Old English word meaning 'bad water', and which was the original name of the River Chelmer. The village is positioned on one of the many elevated hills in Essex and comprises extensive woodlands owned by the National Trust and Essex Naturalist Trust, and is bounded by the River Chelmer to the north. Although there are no shops or businesses in the village, there are two pubs, ''The Generals Arms'' and ''The Rodney'', a village hall, and Elm Green Preparatory School. Churches are the Anglican St Mary the Virgin and the United Reformed Church. St Mary's is a Grade I listed building with a late 11th-century core. It contains a 14th-century ' Devil's door', dating to the time when medieval Christians believed the North of side of a church to be the abode of the Devil. The village sports ground and clubhouse is used by Little Baddow Cricket club and the local running club, Little Baddow "Ri ...

Benjamin Henry Latrobe
Benjamin Henry Boneval Latrobe (May 1, 1764 – September 3, 1820) was an Anglo-American neoclassical architect who emigrated to the United States. He was one of the first formally trained, professional architects in the new United States, drawing on influences from his travels in Italy, as well as British and French Neoclassical architects such as Claude Nicolas Ledoux. In his thirties, he emigrated to the new United States and designed the United States Capitol, on " Capitol Hill" in Washington, D.C., as well as the Old Baltimore Cathedral or The Baltimore Basilica, (later renamed the Basilica of the National Shrine of the Assumption of the Blessed Virgin Mary). It is the first Cathedral constructed in the United States for any Christian denomination. Latrobe also designed the largest structure in America at the time, the "Merchants' Exchange" in Baltimore. With extensive balconied atriums through the wings and a large central rotunda under a low dome which dominated the city ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ipswich And Stowmarket Navigation
The River Gipping is the source river for the River Orwell in the county of Suffolk in East Anglia, England, which is named from the village of Gipping, and which gave its name to the former Gipping Rural District. The name is unrelated to the name of Ipswich. although the County Town takes its name from Gippeswic. It rises near Mendlesham Green and flows in a south-westerly direction to reach Stowmarket. From there it flows towards the south or south east, passing through Needham Market and a number of villages to reach Ipswich, where it becomes the Orwell. The river has supplied power to a number of watermills, several of which are still standing. None is operational, although the mill at Baylham retains most of its machinery, and is the only complete mill on the river. There is evidence that the river was used for navigation in the thirteenth and seventeenth centuries, but in 1790 the Ipswich and Stowmarket Navigation Act 1790 was obtained to enable the river to be improve ...

Chief Engineer
A chief engineer, commonly referred to as "ChEng" or "Chief", is the most senior engine officer of an engine department on a ship, typically a merchant ship, and holds overall leadership and the responsibility of that department..Chief engineer's rank is equivalent to the rank of a ship's captain. As a person who holds one of the most senior roles on the ship, they must have excellent communication and leadership skills. They will be expected to regularly work alongside other crew members and external consultants, and most importantly, provide guidance to their team. To be a chief engineer, an engineer must attain a chief engineer's license appropriate to the tonnage, power rating, and type of ship that they are employed on. A chief engineer is ultimately responsible for all operations and maintenance that has to do with any and all engineering equipment throughout the entire ship, and supervises all other engineering officer and engine ratings within the department.

Robert Whitworth
Robert Whitworth (1734 – 30 March 1799) was an English land surveyor and engineer, who learnt his trade under John Smeaton and James Brindley, and went on to become one of the leading canal engineers of his generation. Biography Whitworth was born in Sowerby, West Riding of Yorkshire to Henry and Mary Whitworth. He was baptised on 15 November 1734, and was their sixth child of seven. His father worked as a combsmith, and the family lived in a house called Waterside or Wheatleyroyd, where he probably lived until he married Sarah Irwin on 26 December 1765. After a brief period in Norton in the Moors around 1772, Whitworth and his family, which by now included two sons, returned to Sowerby, and stayed there until the 1790s. During the latter part of this period he lived in Waterside, but moved to Burnley for the final years of his life, to be closer to the Leeds and Liverpool Canal, on which he was working. He died on 30 March 1799 at the White Lion Inn in Halifax, aged 64. Ear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
