Naviduct
A naviduct is a special class of navigable aqueduct, in which the waterway also includes a lock. One example of a naviduct has been built at Enkhuizen on the Houtribdijk in the Netherlands on the instructions of the Rijkswaterstaat. This cost over €55 million and was completed in 2003. It is big enough to simultaneously transfer two large Rhine river-barges from the Markermeer to the IJsselmeer or vice versa. The structure was chosen because a busy waterway crosses a dam carrying a busy road, but the space available for separate aqueduct and lock facilities was restricted. Name and definition The term is derived from the words for navigation and aqueduct, which are in turn partly derived from the Latin words ''navis'' meaning ship and ''ducere'' meaning to lead or conduct. It can also be thought of as a lock system with an underpass under the lock for road traffic. The term is introduced and used extensively in the Netherlands for referring to the works near Enkhuizen in Dutch a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Navigable Aqueduct
Navigable aqueducts (sometimes called water bridges) are bridge structures that carry navigable waterway canals over other rivers, valleys, railways or roads. They are primarily distinguished by their size, carrying a larger cross-section of water than most water-supply aqueducts. Roman aqueducts were used to transport water and were created in Ancient Rome. The long steel Briare aqueduct carrying the Canal latéral à la Loire over the River Loire was built in 1896. It was ranked as the longest navigable aqueduct in the world for more than a century, until the Magdeburg Water Bridge in Germany took the title in the early 21st century. Early aqueducts such as the three on the Canal du Midi had stone or brick arches, the longest span being on the Cesse Aqueduct, built in 1690. But, the weight of the construction to support the trough with the clay or other lining to make it waterproof made these structures clumsy. In 1796 Longdon-on-Tern Aqueduct, the first large cast iron aqu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Afsluitdijk
The ''Afsluitdijk'' (; fry, Ofslútdyk; nds-nl, Ofsluutdiek; en, "Closure Dyke") is a major dam and causeway in the Netherlands. It was constructed between 1927 and 1932 and runs from Den Oever in North Holland province to the village of Zurich in Friesland province, over a length of and a width of , at an initial height of above sea level. The ''Afsluitdijk'' is a fundamental part of the larger Zuiderzee Works, damming off the Zuiderzee, a salt water inlet of the North Sea, and turning it into the fresh water lake of the IJsselmeer. It is a major landwinning project and a quicker road-connection between the North and West of the Netherlands. The motorway on the ''Afsluitdijk'' was the initial demonstration site for a speed limit in the Netherlands. History Reasons for construction The Afsluitdijk (literally translated: shut-off-dyke) was completed in 1932, thereby shutting off the Zuiderzee (lit: Southern Sea) from the North Sea. Until then, the Zuiderzee had b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

State Secretary (Netherlands)
Undersecretary (or under secretary) is a title for a person who works for and has a lower rank than a secretary (person in charge). It is used in the executive branch of government, with different meanings in different political systems, and is also used in other organizational settings. In government, the position may be a junior government minister (e.g. a parliamentary secretary) who assists a secretary of state. In other cases, the position may be a senior government official, frequently a career public servant, who typically acts as a senior administrator. The senior administrator may be considered a second-in-command to a politically appointed cabinet minister or other government official (e.g. in the United States), or they may be considered a head or chief executive of a government department (e.g. a permanent secretary). Some systems of government have both types of position, as in the United Kingdom where the title has been in use since the 17th century. Holy See In th ...

Chesapeake And Ohio Canal
The Chesapeake and Ohio Canal, abbreviated as the C&O Canal and occasionally called the "Grand Old Ditch," operated from 1831 until 1924 along the Potomac River between Washington, D.C. and Cumberland, Maryland. It replaced the Potomac Canal, which shut down completely in 1828, and could operate during months in which the water level was too low for the former canal. The canal's principal cargo was coal from the Allegheny Mountains. Construction on the canal began in 1828 and ended in 1850 with the completion of a stretch to Cumberland, although the Baltimore and Ohio Railroad had already reached Cumberland in 1842. Rising and falling over an elevation change of , it required the construction of 74 Lock (water transport), canal locks, 11 Navigable aqueduct, aqueducts to cross major streams, more than 240 culverts to cross smaller streams, and the Paw Paw Tunnel. A planned section to the Ohio River at Pittsburgh was never built. The canalway is now maintained as the Chesapeake ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seneca Aqueduct
Seneca Aqueduct — or Aqueduct No. 1 — is a naviduct that carries the Chesapeake and Ohio Canal (C&O) over Seneca Creek in Montgomery County, Maryland. The C&O built eleven aqueducts along its length. Seneca Aqueduct is a unique structure, not only being the first built, but also the only red sandstone aqueduct on the C&O−and the only aqueduct that is also a lock (Lock 24, or Riley's Lock). It is located at the end of Riley's Lock Road in Seneca, Maryland. History Seneca Aqueduct was built from 1829 to 1832 with three red sandstone arches quarried in the nearby Seneca Quarry, just a few hundred feet to the west. The initial stretch of the C&O Canal opened in 1830 up to Lock 23 and Inlet Lock 2, one lock downstream from the Seneca Aqueduct. The segment from Seneca Aqueduct to Harpers Ferry opened in 1833. This included a sizable turning basin, just west of the aqueduct, where canal boats could anchor or turn around. Next to the aqueduct and lock is the lock keeper's house, a ...

Boat Entering Lock 24 Rileys Lock
A boat is a watercraft of a large range of types and sizes, but generally smaller than a ship, which is distinguished by its larger size, shape, cargo or passenger capacity, or its ability to carry boats. Small boats are typically found on inland waterways such as rivers and lakes, or in protected coastal areas. However, some boats, such as the whaleboat, were intended for use in an offshore environment. In modern naval terms, a boat is a vessel small enough to be carried aboard a ship. Boats vary in proportion and construction methods with their intended purpose, available materials, or local traditions. Canoes have been used since prehistoric times and remain in use throughout the world for transportation, fishing, and sport. Fishing boats vary widely in style partly to match local conditions. Pleasure craft used in recreational boating include ski boats, pontoon boats, and sailboats. House boats may be used for vacationing or long-term residence. Lighters are used to convey ...

Barge
Barge nowadays generally refers to a flat-bottomed inland waterway vessel which does not have its own means of mechanical propulsion. The first modern barges were pulled by tugs, but nowadays most are pushed by pusher boats, or other vessels. The term barge has a rich history, and therefore there are many other types of barges. History of the barge Etymology "Barge" is attested from 1300, from Old French ''barge'', from Vulgar Latin ''barga''. The word originally could refer to any small boat; the modern meaning arose around 1480. ''Bark'' "small ship" is attested from 1420, from Old French ''barque'', from Vulgar Latin ''barca'' (400 AD). The more precise meaning of Barque as "three-masted sailing vessel" arose in the 17th century, and often takes the French spelling for disambiguation. Both are probably derived from the Latin ''barica'', from Greek ''baris'' "Egyptian boat", from Coptic ''bari'' "small boat", hieroglyphic Egyptian D58-G29-M17-M17-D21-P1 and similar ''b ...

CEMT Class
The Classification of European Inland Waterways is a set of standards for interoperability of large navigable waterways forming part of the Trans-European Inland Waterway network within Continental Europe and Russia. It was created by the European Conference of Ministers of Transport (ECMT; french: Conférence européenne des ministres des Transports, ) in 1992, hence the range of dimensions are also referred to as CEMT Class I–VII. The size for each waterway is limited by the dimensions of the structures including the locks and boat lifts on the route. Classification Class I corresponds to the historical Freycinet gauge decreed in France during 1879. The larger river classification sizes are focused on the carriage of intermodal containers in convoys of barges propelled by a push-tug. Most of the canals of the United Kingdom have smaller locks and would fall below the dimensions in the European classification system. In 2004, the standards were extended with four smaller si ...
