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.

Delta Plan
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 c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Satellite Image Of Europoort, Netherlands (4
A satellite or artificial satellite is an object intentionally placed into orbit in outer space. Except for passive satellites, most satellites have an electricity generation system for equipment on board, such as solar panels or radioisotope thermoelectric generators (RTGs). Most satellites also have a method of communication to ground stations, called transponders. Many satellites use a standardized bus to save cost and work, the most popular of which is small CubeSats. Similar satellites can work together as a group, forming constellations. Because of the high launch cost to space, satellites are designed to be as lightweight and robust as possible. Most communication satellites are radio relay stations in orbit and carry dozens of transponders, each with a bandwidth of tens of megahertz. Satellites are placed from the surface to orbit by launch vehicles, high enough to avoid orbital decay by the atmosphere. Satellites can then change or maintain the orbit by propulsion, ...

Flood Barriers In South Holland
A flood is an overflow of water ( or rarely other fluids) that submerges land that is usually dry. In the sense of "flowing water", the word may also be applied to the inflow of the tide. Floods are an area of study of the discipline hydrology and are of significant concern in agriculture, civil engineering and public health. Human changes to the environment often increase the intensity and frequency of flooding, for example land use changes such as deforestation and removal of wetlands, changes in waterway course or flood controls such as with levees, and larger environmental issues such as climate change and sea level rise. In particular climate change's increased rainfall and extreme weather events increases the severity of other causes for flooding, resulting in more intense floods and increased flood risk. Flooding may occur as an overflow of water from water bodies, such as a river, lake, or ocean, in which the water overtops or breaks levees, resulting in some of ...

Hook Of Holland
Hook of Holland ( nl, Hoek van Holland, ) is a town in the southwestern corner of Holland, hence the name; ''hoek'' means "corner" and was the word in use before the word ''kaap'' – "cape", from Portuguese ''cabo'' – became Dutch. The English translation using Hook is a false cognate of the Dutch Hoek, but has become commonplace (in official government records in English, the name tends not to get translated and Hoek van Holland is used). It is located at the mouth of the New Waterway shipping canal into the North Sea. The town is administered by the municipality of Rotterdam as a district of that city. Its district covers an area of 16.7 km2, of which 13.92 km2 is land. On 1 January 1999 it had an estimated population of 9,400. Towns near "the Hook" ( nl, "de Hoek") include Monster, 's-Gravenzande, Naaldwijk and Delft to the northeast, and Maassluis to the southeast. On the other side of the river is the Europort and the Maasvlakte. The wide sandy beach, one sectio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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 ...
