Headworks
Headworks is a civil engineering term for any structure at the head or diversion point of a waterway. It is smaller than a barrage and is used to divert water from a river into a canal or from a large canal into a smaller canal. at Web archive An example is the Horseshoe falls at the start of the Llangollen canal. Historically the phrase "headworks" derives from the traditional approach of diverting water at the start of an irrigation network and the location of these processes at the "head of the works".

Barrage (dam)
A barrage is a type of low-head, diversion dam which consists of a number of large gates that can be opened or closed to control the amount of water passing through. This allows the structure to regulate and stabilize river water elevation upstream for use in irrigation and other systems. The gates are set between flanking piers which are responsible for supporting the water load of the pool created. The term '' barrage'' is borrowed from the French word "barrer" meaning "to bar". Dam construction Barrage dams have a series of gates that control the amount of water passing through it. A barrage dam can be used to divert water for irrigation needs or limit the amount of water down-stream. In most cases, a barrage dam is built near the mouth of the river. The site of dam construction needs to be thoroughly investigated to ensure that the foundation is strong enough to support the dam and has low possibility of failing. When dams are created, they are given a safety rating dep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Wiley & Sons
John Wiley & Sons, Inc., commonly known as Wiley (), is an American multinational publishing company founded in 1807 that focuses on academic publishing and instructional materials. The company produces books, journals, and encyclopedias, in print and electronically, as well as online products and services, training materials, and educational materials for undergraduate, graduate, and continuing education students. History The company was established in 1807 when Charles Wiley opened a print shop in Manhattan. The company was the publisher of 19th century American literary figures like James Fenimore Cooper, Washington Irving, Herman Melville, and Edgar Allan Poe, as well as of legal, religious, and other non-fiction titles. The firm took its current name in 1865. Wiley later shifted its focus to scientific, technical, and engineering subject areas, abandoning its literary interests. Wiley's son John (born in Flatbush, New York, October 4, 1808; died in East Orange, New Je ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Web Archive
The Web ARChive (WARC) archive format specifies a method for combining multiple digital resources into an aggregate archive file together with related information. The WARC format is a revision of the Internet Archive's ARC_IA File Format that has traditionally been used to store " web crawls" as sequences of content blocks harvested from the World Wide Web. The WARC format generalizes the older format to better support the harvesting, access, and exchange needs of archiving organizations. Besides the primary content currently recorded, the revision accommodates related secondary content, such as assigned metadata, abbreviated duplicate detection events, and later-date transformations. The WARC format is inspired by HTTP/1.0 streams, with a similar header and the use of CRLFs as delimiters, making it very conducive to crawler implementations. First specified in 2008, WARC is now recognised by most national library systems as the standard to follow for web archiving. Software * ...

Horseshoe Falls (Wales)
Horseshoe Falls (Welsh: ''Rhaeadr y Bedol'') () is a weir on the River Dee near Llantysilio Hall in Denbighshire, Wales, about north-west of the town of Llangollen. History The distinctively shaped weir, which is long, helps create a pool of water that can enter the Llangollen Canal (via an adjacent valve house and flow meter). The canal west of Pontcysyllte Aqueduct and the construction of the weir were authorised by an Act of Parliament obtained in 1804 by the Ellesmere Canal Company. The canal was a navigable feeder, which supplied water to the Ellesmere Canal beyond Pontcysyllte, and to the Chester Canal, to which it connected near Nantwich. Thomas Telford was the civil engineer responsible for the design, and the canal and feeder were completed in 1808. The weir was an important factor in the retention of the canal to Llangollen when the owners of the entire Shropshire Union system, the London, Midland and Scottish Railway, decided to close much of the network in 1944. ...

Llangollen Canal
The Llangollen Canal ( cy, Camlas Llangollen) is a navigable canal crossing the border between England and Wales. The waterway links Llangollen in Denbighshire, north Wales, with Hurleston in south Cheshire, via the town of Ellesmere, Shropshire. The name, which was coined in the 1980s, is a modern designation for parts of the historic Ellesmere Canal and the Llangollen navigable feeder, both of which became part of the Shropshire Union Canals in 1846. The Ellesmere Canal was proposed by industrialists at Ruabon and Brymbo, and two disconnected sections were built. The northern section ran from Ellesmere Port on the River Mersey to Chester, where it joined the Chester Canal, and opened in 1795. Work on the southern section began at Frankton, with a line southwards to Llanymynech, and subsequently, a second section was built westwards towards Trevor. This involved crossing the Afon Ceiriog and the River Dee, which was achieved by building two vast aqueducts, using iron tro ...

Civil Engineering
Civil engineering is a professional engineering discipline that deals with the design, construction, and maintenance of the physical and naturally built environment, including public works such as roads, bridges, canals, dams, airports, sewage systems, pipelines, structural components of buildings, and railways. Civil engineering is traditionally broken into a number of sub-disciplines. It is considered the second-oldest engineering discipline after military engineering, and it is defined to distinguish non-military engineering from military engineering. Civil engineering can take place in the public sector from municipal public works departments through to federal government agencies, and in the private sector from locally based firms to global Fortune 500 companies. History Civil engineering as a discipline Civil engineering is the application of physical and scientific principles for solving the problems of society, and its history is intricately linked to advances in t ...
