Den Oever Lighthouse
The Den Oever Lighthouse is a cast iron lighthouse in Den Oever, the Netherlands, on the Wadden Sea. Erected in 1885, it was originally located at the western end of the former island of Wieringen where it served as the rear light of a pair of leading lights. In 1930, when the Afsluitdijk was finished, the tower was relocated to the eastern end of Wieringen at Den Oever. While the light was first directed the Wadden Sea, it was moved southward in 1932 and turned to face the IJsselmeer. It was deactivated in 2009. A previous lighthouse in Den Oever was established in 1918. It was moved to Zeughoek in 1930. See also * List of lighthouses in the Netherlands A list of lighthouses in the Netherlands.

Den Oever
Den Oever (; in English, the ''shore, the coast'') is a village in the Dutch province of North Holland. It is a part of the municipality of Hollands Kroon, and lies about east of Den Helder. Overview The village was first mentioned in 1432 as "ten Oisterlande op 't Oever", and means "(on the sea) shore", because it was an access point to the former Zuiderzee. Den Oever was a fishing village which developed in the Late Middle Ages on the north-eastern edge of the former Wieringen island. The village is located on the former island Wieringen at the west side of the Afsluitdijk: therefore the Stevin lock (named after mathematician and engineer Simon Stevin) and three series of five sluices for discharging the IJsselmeer into the Wadden Sea were constructed in Den Oever. The eight-sided wooden grain smock mill "De Hoop" ("The Hope") is situated in the middle of the village with a wingspan of . It dates back into the 17th century (1654) and has been completely restored in the sec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Candela
The candela ( or ; symbol: cd) is the unit of luminous intensity in the International System of Units (SI). It measures luminous power per unit solid angle emitted by a light source in a particular direction. Luminous intensity is analogous to radiant intensity, but instead of simply adding up the contributions of every wavelength of light in the source's spectrum, the contribution of each wavelength is weighted by the standard luminosity function (a model of the sensitivity of the human eye to different wavelengths). A common wax candle emits light with a luminous intensity of roughly one candela. If emission in some directions is blocked by an opaque barrier, the emission would still be approximately one candela in the directions that are not obscured. The word ''candela'' is Latin for ''candle''. The old name "candle" is still sometimes used, as in ''foot-candle'' and the modern definition of ''candlepower''.

Cast Iron
Cast iron is a class of iron–carbon alloys with a carbon content more than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its color when fractured: white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and ductile cast iron has spherical graphite "nodules" which stop the crack from further progressing. Carbon (C), ranging from 1.8 to 4 wt%, and silicon (Si), 1–3 wt%, are the main alloying elements of cast iron. Iron alloys with lower carbon content are known as steel. Cast iron tends to be brittle, except for malleable cast irons. With its relatively low melting point, good fluidity, castability, excellent machinability, resistance to deformation and wear resistance, cast irons have become an engineering material with a wide range of applications and are ...

Lighthouse
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lenses and to serve as a beacon for navigational aid, for maritime pilots at sea or on inland waterways. Lighthouses mark dangerous coastlines, hazardous shoals, reefs, rocks, and safe entries to harbors; they also assist in aerial navigation. Once widely used, the number of operational lighthouses has declined due to the expense of maintenance and has become uneconomical since the advent of much cheaper, more sophisticated and effective electronic navigational systems. History Ancient lighthouses Before the development of clearly defined ports, mariners were guided by fires built on hilltops. Since elevating the fire would improve the visibility, placing the fire on a platform became a practice that led to the development of the lighthouse. In antiquity, the lighthouse functioned more as an entrance marker to ports than as a warning signal for reefs a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wadden Sea
The Wadden Sea ( nl, Waddenzee ; german: Wattenmeer; nds, Wattensee or ; da, Vadehavet; fy, Waadsee, longname=yes; frr, di Heef) is an intertidal zone in the southeastern part of the North Sea. It lies between the coast of northwestern continental Europe and the range of low-lying Frisian Islands, forming a shallow body of water with tidal flats and wetlands. It has a high biological diversity and is an important area for both breeding and migrating birds. In 2009, the Dutch and German parts of the Wadden Sea were inscribed on UNESCO's World Heritage List and the Danish part was added in June 2014. The Wadden Sea stretches from Den Helder, in the northwest of the Netherlands, past the great river estuaries of Germany to its northern boundary at Skallingen in Denmark along a total coastline of some and a total area of about . Within the Netherlands, it is bounded from the IJsselmeer by the Afsluitdijk. Historically, the coastal regions were often subjected to large floods, r ...

Wieringen
Wieringen () is part of the municipality of Hollands Kroon, established in 2012 in the province of North Holland in the Netherlands. It is a former municipality in this province, with its name appearing in records of the late 9th and early 10th century. From 1200 it was known as an island, also named Wieringen, which was separated by water from the mainland during one of the disastrous storm floods towards the end of the late Middle Ages that changed the coastline. By draining, dikes and landfill from 1924 to 1932, the island was rejoined to the mainland. In the 21st century, the local governments proposed a project to restore the insular status of Wieringen by construction of a recreational lake to be called the Wieringerrandmeer. The project was cancelled in 2010 for financial reasons. Population centres The former municipality of Wieringen consisted of the following cities, towns, villages and/or districts: Dam, De Haukes, De Hoelm, Den Oever, Hippolytushoef, Hollebalg, N ...

Leading Lights
Leading lights (also known as range lights in the United States) are a pair of light beacons used in navigation to indicate a safe passage for vessels entering a shallow or dangerous channel; they may also be used for position fixing. At night, the lights are a form of leading line that can be used for safe navigation. The beacons consist of two lights that are separated in distance and elevation, so that when they are aligned, with one above the other, they provide a bearing. Range lights are often illuminated day and night. In some cases the two beacons are unlighted, in which case they are known as a range in the United States or a transit in the UK. The beacons may be artificial or natural. Operation Two lights are positioned near one another. One, called the front light, is lower than the one behind, which is called the rear light. At night when viewed from a ship, the two lights only become aligned vertically when a vessel is positioned on the correct bearing. During t ...

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] |
IJsselmeer
The IJsselmeer (; fy, Iselmar, nds-nl, Iesselmeer), also known as Lake IJssel in English, is a closed off inland bay in the central Netherlands bordering the provinces of Flevoland, North Holland and Friesland. It covers an area of with an average depth of . The river IJssel flows into the IJsselmeer. History Two thousand years ago Pomponius Mela, a Roman geographer, mentioned a complex of lakes at the current location of the IJsselmeer. He called it ''Lacus Flevo''. Over the centuries, the lake banks crumbled away due to flooding and wave action and the lake, now called the Almere, grew considerably. During the 12th and 13th centuries, storm surges and rising sea levels flooded large areas of land between the lake and the North Sea, turning the lake into a bay of the North Sea, called the Zuiderzee. The Zuiderzee continued to be a threat to the Dutch, especially when northwesterly storms funnel North Sea waters towards the English Channel, creating very high tides along ...
