Afsluitdijk 1031
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, Friesland, 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, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

North Sea Canal
The North Sea Canal ( nl, Noordzeekanaal) is a Dutch ship canal from Amsterdam to the North Sea at IJmuiden, constructed between 1865 and 1876 to enable seafaring vessels to reach the port of Amsterdam. This man-made channel terminates at Amsterdam in the closed-off IJ Bay, which in turn connects to the Amsterdam-Rhine Canal. The drainage of the canal to the North Sea is done through the Spui Locks at IJmuiden, augmented by the largest pumping station in Europe. This system is vital to the groundwater management of the Western Netherlands. History To improve the connection between the harbour of Amsterdam and the North Sea, the North Holland Canal was built in 1824. But this long and narrow canal was quickly inadequate to handle the growing boat traffic. A few decades later it was decided to dig a new canal at the narrowest point in Holland and thereby providing the shortest route to the sea. Digging began on 8 March 1865, at the dunes of Breesaap and lasted until 1876. Sin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Till
image:Geschiebemergel.JPG, Closeup of glacial till. Note that the larger grains (pebbles and gravel) in the till are completely surrounded by the matrix of finer material (silt and sand), and this characteristic, known as ''matrix support'', is diagnostic of till. image:Glacial till exposed in roadcut-750px.jpg, Glacial till with tufts of grass Till or glacial till is unsorted glacier, glacial sediment. Till is derived from the erosion and entrainment of material by the moving ice of a glacier. It is deposited some distance down-ice to form terminal, lateral, medial and ground moraines. Till is classified into primary deposits, laid down directly by glaciers, and secondary deposits, reworked by fluvial transport and other processes. Description Till is a form of '' glacial drift'', which is rock material transported by a glacier and deposited directly from the ice or from running water emerging from the ice. It is distinguished from other forms of drift in that it is depos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basalt
Basalt (; ) is an aphanite, aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the planetary surface, surface of a terrestrial planet, rocky planet or natural satellite, moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed by geologists at about 20 volcanoes per year. Basalt is also an important rock type on other planetary bodies in the Solar System. For example, the bulk of the plains of volcanism on Venus, Venus, which cover ~80% of the surface, are basaltic; the lunar mare, lunar maria are plains of flood-basaltic lava flows; and basalt is a common rock on the surface of Mars. Molten basalt lava has a low viscosity due to its relatively low silica content (between 45% and 52%), resulting in rapidly moving lava flo ...

Gabion
A gabion (from Italian ''gabbione'' meaning "big cage"; from Italian ''gabbia'' and Latin ''cavea'' meaning "cage") is a cage, cylinder or box filled with rocks, concrete, or sometimes sand and soil for use in civil engineering, road building, military applications and landscaping. For erosion control, caged riprap is used. For dams or in foundation construction, cylindrical metal structures are used. In a military context, earth- or sand-filled gabions are used to protect sappers, infantry, and artillerymen from enemy fire. Leonardo da Vinci designed a type of gabion called a ''Corbeille Leonard'' ("Leonard basket") for the foundations of the San Marco Castle in Milan. Civil engineering The most common civil engineering use of gabions was refined and patented by Gaetano Maccaferri in the late 19th century in Sacerno, Emilia Romagna and used to stabilize shorelines, stream banks or slopes against erosion. Other uses include retaining walls, noise barriers, temporary flood w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Melaleuca Uncinata
''Melaleuca uncinata'', commonly known as broombush, broom honeymyrtle or brushwood, is a plant in the paperbark family native to southern Australia. It is harvested from the wild, and grown in plantations, for broombush fencing. The Noongar names for the plant are kwytyat and yilbarra. Description Broombush is a multistemmed evergreen shrub usually less than in height, occasionally growing as a small tree to less than . It is often found in association with mallee eucalypts. It has spreading or ascending leaves, long and wide, linear in shape, almost circular in cross-section, and tapering to a distinctly curved hook. The leaves have large oil glands along their edges. The flowers are white, cream or yellow, and are attractive to birds. They are arranged in dense almost spherical heads, in diameter in the leaf axils. Each head contains 4 to 19 groups of flowers, each group with 3 flowers. The stamens are arranged in five bundles around the flower, each bundle with 3 to 5 ...

Boulder Clay
Boulder clay is an unsorted agglomeration of clastic sediment that is unstratified and structureless and contains gravel of various sizes, shapes, and compositions distributed at random in a fine-grained matrix. The fine-grained matrix consists of stiff, hard, pulverized clay or rock flour. Boulder clay is also know as either known as drift clay; till; unstratified drift, geschiebelehm (German); argile á blocaux (French); and keileem (Dutch).Charlesworth, J. K., 1957.

Amsteldiepdijk
Amsteldiepdijk is a dike between Van Ewijcksluis and the island of Wieringen. It was built in 1924 and closes a portion of the Amsteldiep and of the Ulkediep. It is often considered to be the first work of engineering of the Zuiderzee works. With the small dike, the former island (1200 to 1932) of Wieringen is connected on the western side with the mainland of North Holland and is no longer an island. The dam serves as a prototype in some way to works to come on the future IJsselmeer. Some errors served as lessons. A collapse is still visible on the side of the lake Amstelmeer. The government decided that it was the fault of the contractor, and ultimately he had to pay damages to the state. Prime contractors joined forces in a consortium, the ''Society for the implementation of work of the Zuiderzee''.D.J. Wolffram, 70 jaar ingenieurskunst. Dienst der Zuiderzeewerken 1919-1989 (Lelystad 1997) This ''small dike'' is important as the first time that boulder clay was used in the con ...

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 ...

1917 Potato Riots
The Potato riots in June–July 1917 was a popular uprising in the Dutch capital city Amsterdam that was caused by the food shortage in the Netherlands during World War I. History In the beginning of the 20th century, food was more within the reach of the workers. The First World War changed this. The Netherlands remained a neutral country, but experienced discomfort and hard circumstances. Imports and exports of goods stagnated. Bread and other food was rationed and soup kitchens sprang up. A bread ration was established in January 1917. On 28 June 1917, there was a shortage of potatoes. It became known in the neighborhoods of Amsterdam that there was a ship with potatoes in the Prinsengracht, but these were for the army. In order to feed their families, the working women of the Eastern Islands and the Czar Peter Neighborhood plundered the ship. According to the Councillor Josephus Jitta, there was no overall shortage of food as the workers had an extra supply of rice provi ...

Flood Of 1916
The flood of 1916 or Zuiderzeevloed of 1916 is a flood that took place in the night between 13 and 14 January 1916 in the Netherlands along the dikes of the Zuiderzee as a result of a storm surge. Course The flood coincided with a high water inflow of rivers causing many ruptures and structural damage in levees at dozens of places along the coastline. Some wooden houses on the island of Marken completely tumbled over. In the province North Holland 19 people were killed, while at sea several ships were wrecked causing another 32 casualties. Queen Wilhelmina of the Netherlands, Wilhelmina visited the areas that were hit. Consequences This disaster, in combination with the famine caused by the First World War, led to a law called the Zuiderzeewet. The reinforcement of the levees, undertaken after the disaster, was finished in 1926. In 1932, the Zuiderzee was 'tamed' by constructing a 32-kilometre long levee, a barrage called the Afsluitdijk. For the fishermen, this also led to th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
