Hartelkering
The Hartelkering (English: Hartel barrier) is a storm surge barrier in Spijkenisse, Netherlands. The barrier is part of the Europoortkering, itself part of the Delta Works project and is designed to close the Hartelkanaal in case of a storm surge. The barrier consists of two vertical lift gates, and in length. The gates have a height of above NAP when closed. The waterlevel at this location can become higher, but in order to prevent flooding of the Europoort-area the gates were designed to allow the water to overtop the gates in extreme situations. The amount of water would be too small to cause any problems in the protected area but it does limit the surgelevel in the unprotected areas. In the raised position the bottom of the gates is at above NAP, slightly higher than the bridge next to the barrier. The barrier is equipped with a construction to fend off floating debris, which could damage the gates. The Hartelkering was constructed at the same time as the Maeslantkeri ...

Delta Works
The Delta Works ( nl, Deltawerken) is a series of construction projects in the southwest of the Netherlands to protect a large area of land around the Rhine–Meuse–Scheldt delta from the sea. Constructed between 1954 and 1997, the works consist of dams, sluices, locks, dykes, levees, and storm surge barriers located in the provinces of South Holland and Zeeland. The aim of the dams, sluices, and storm surge barriers was to shorten the Dutch coastline, thus reducing the number of dikes that had to be raised. Along with the Zuiderzee Works, the Delta Works have been declared one of the Seven Wonders of the Modern World by the American Society of Civil Engineers. History The estuaries of the rivers Rhine, Meuse and Schelde have been subject to flooding over the centuries. After building the Afsluitdijk (19271932), the Dutch started studying the damming of the Rhine-Meuse Delta. Plans were developed to shorten the coastline and turn the delta into a group of freshwater ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Europoortkering
The Europoortkering or barrier of the Europoort is a program of engineering works in addition to the Delta Plan, designed to protect the maritime access routes from the port of Rotterdam and thus, the entire South Holland against storms and tides. The original Delta Plan provided no closure of the Western Scheldt and of the Nieuwe Waterweg to allow access to the ports of Antwerp and Rotterdam. But regarding the Nieuwe Waterweg and the Hartelkanaal it appeared in the mid-1980s that the levees were not high enough to ensure optimum protection of the territories densely populated South Holland. A heightening of all dikes would be too expensive. An alternative was found. In 1987 the final decision was taken, the Nieuwe Waterweg will be protected by dikes up to the location of a storm surge barrier, the Maeslantkering at Hook of Holland, and the Hartelkanaal will be protected up to another storm surge barrier, the Hartelkering. Between those two barriers, the raising of all dikes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maeslantkering
The Maeslantkering ("Maeslant barrier" in Dutch) is a storm surge barrier on the Nieuwe Waterweg, in South Holland, Netherlands. It was constructed from 1991 to 1997. As part of the Delta Works the barrier responds to water level predictions calculated by a centralized computer system called BOS. It automatically closes when Rotterdam (especially the Port of Rotterdam) is threatened by floods. Maeslantkering has two 210-metre long barrier gates, with two 237-metre long steel trusses holding them. When closed, the barrier will protect the entire width (360 metres) of the Nieuwe Waterweg, the main waterway of Port of Rotterdam. It is one of the largest moving structures on Earth, rivalling the Green Bank Telescope in the United States and the Bagger 288 excavator in Germany. The Maeslant Barrier The initial plan The construction of the Maeslantkering was a part of the Europoortkering project which, in turn, was the final stage of the Delta Works. The main objective of this Euro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flood Barrier
A flood barrier, surge barrier or storm surge barrier is a specific type of floodgate, designed to prevent a storm surge or spring tide from flooding the protected area behind the barrier. A surge barrier is almost always part of a larger flood protection system consisting of floodwalls, levees (also known as dikes), and other constructions and natural geographical features. Flood barrier may also refer to barriers placed around or at individual buildings to keep floodwaters from entering the buildings. Examples Delta Works The Delta Works in the Netherlands is the largest flood protection project in the world. This project consists of a number of surge barriers, the Oosterscheldekering being the largest surge barrier in the world, long. Other examples include the Maeslantkering, Haringvlietdam and the Hartelkering. Thames Barrier The Thames Barrier is the world's second largest movable flood barrier (after the Oosterscheldekering and the Haringvlietdam) and is locate ...

Spijkenisse
Spijkenisse () is a city in the province of South Holland, Netherlands. Following an administrative reform in 2015, it is part of the municipality of Nissewaard, and has a population of 72,500. It covers an area of of which is water. It is part of the Greater Rotterdam area. History Archaeological evidence suggests that the area around Spijkenisse has been inhabited for several thousand years. The area's prehistoric inhabitants depended on fishing in the Maas and hunting in the surrounding swamps for sustenance. Spijkenisse also has an anthem, the song is called "Spijkenisse" by Rik Hoogendoorn. The song was released in 2012 and is very popular amongst people who live in Spijkenisse. The oldest known reference to the name ''Spickenisse'' is in a source from 1231. Spijkenisse is a portmanteau of the words ' ( spit) and ''nesse'' (nose) meaning "pointy nose." The name is a reference to the settlement's location on a spit of land protruding into the river. Spijkenisse formed as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rijkswaterstaat
Rijkswaterstaat, founded in 1798 as the ''Bureau voor den Waterstaat'' and formerly translated to Directorate General for Public Works and Water Management, is a Directorate-General of the Ministry of Infrastructure and Water Management of the Netherlands. Its role is the practical execution of the public works and water management, including the construction and maintenance of waterways and roads, and flood protection and prevention. The agency was also involved in the construction of big railway projects such as the Betuweroute and the HSL-Zuid. The mission of the organisation is: "Rijkswaterstaat is de rijksdienst die werkt aan droge voeten, schoon en voldoende water én aan de vlotte en veilige doorstroming van het verkeer" (Rijkswaterstaat is the national agency that provides dry feet, clean and sufficient water and a quick and safe flow of traffic). The agency is divided in 10 regional, 6 specialist services and 2 special services. As of 15 May 2017, the director-general (DG ...

Storm Surge
A storm surge, storm flood, tidal surge, or storm tide is a coastal flood or tsunami-like phenomenon of rising water commonly associated with low-pressure weather systems, such as cyclones. It is measured as the rise in water level above the normal tidal level, and does not include waves. The main meteorological factor contributing to a storm surge is high-speed wind pushing water towards the coast over a long fetch. Other factors affecting storm surge severity include the shallowness and orientation of the water body in the storm path, the timing of tides, and the atmospheric pressure drop due to the storm. There is a suggestion that climate change may be increasing the hazard of storm surges. Some theorize that as extreme weather becomes more intense and sea level rises due to climate change, storm surge is expected to cause more risk to coastal populations. Communities and governments can adapt by building hard infrastructure, like surge barriers, soft infrastructure, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Normaal Amsterdams Peil
Amsterdam Ordnance Datum or ' (NAP) is a vertical datum in use in large parts of Western Europe. Originally created for use in the Netherlands, its height was used by Prussia in 1879 for defining ', and in 1955 by other European countries. In the 1990s, it was used as the reference level for the United European leveling Network (UELN) which in turn led to the European Vertical Reference System (EVRS). Mayor Johannes Hudde of Amsterdam in a way came up with the idea after he expanded the sea dike after a flood in Amsterdam in 1675. Of course a dike should be storm-resistant to protect a city against flooding, and in this case a margin of "9 feet and 5 inches" (2.67 m - margin is defined in Amsterdam feet) was deemed enough to cope with rising water. So he measured the water level of the adjacent sea arm, ' and compared it with the water level in the canals within the city itself. He found that the water level at an average summer flood in the sea arm (when the water level reac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Europoort
Europoort (, en, Eurogate, also "Europort") is an area of the Port of Rotterdam and the adjoining industrial area in the Netherlands. Being situated at Southside of the mouth of the rivers Rhine and Meuse with the hinterland consisting of the Netherlands, Germany, Belgium and partly France, Europoort is one of the world's busiest ports and considered a major entry to Europe. The port handled 12 million containers in 2015. The Europoort area is very heavily industrialised with petrochemical refineries and storage tanks, bulk iron ore and coal handling as well as container and new motor vehicle terminals. Europoort is situated on the South bank of the Nieuwe Waterweg, same as the Maasvlakte area. On the Northern bank of the Nieuwe Waterweg one could find Hook of Holland (in Dutch: Hoek van Holland). Development of Europoort Rotterdam has developed from a small town into a major harbour city. In earlier centuries, docks were built on the banks of the Nieuwe Maas river. In the 1 ...
