H. Wortman Pumping Station
The H. Wortman Pumping Station () is a pumping station in Lelystad, Flevoland, the Netherlands. Named for Hendrik Wortman, a civil engineer who contributed to the Zuiderzee Works, the station was designed by Dirk Roosenburg and completed in 1956. It was used for the reclamation of the eastern Flevopolder in 1957, and contributed to the reclamation of the polder's southern areas. It was declared a municipal monument in 2017. Design and layout The Wortman Pumping Station is situated at Oostvaardersdijk 32 in Lelystad, Flevoland, the Netherlands. It consists of a series of blocks, built atop a concrete substructure that contains the suction and pressure shafts. Central is a one-storey machine hall with a mastic gable roof. To the side of the hall are various service rooms, spread across two storeys. The superstructure is built on a concrete frame, filled with alternating brick and glass facades; these glass panes were initially framed in steel, but are currently framed in aluminiu ...

Lelystad
Lelystad () is a Dutch Municipalities of the Netherlands, municipality and the capital city of the province of Flevoland in the central Netherlands. The city, built on reclaimed land, was founded in 1967 and was named after Cornelis Lely, who engineered the Afsluitdijk that made the reclamation possible. Lelystad is situated approximately three metres (10 feet) below sea level. History Lelystad is built on the seabed of the former Zuiderzee. About 6,500 years ago, this wetland was above high tide level and inhabited; the Netherlands have steadily subsided since. Near Lelystad at Swifterbant, the oldest human skeletons in Western Europe were discovered. Due to Floods in the Netherlands, rising water levels and storms, the peatlands were washed away, and the Lake Flevo, Lacus Flevo (in Roman times) grew to be the Almere (lake), Almere (Middle Ages) and became the Zuiderzee. The Zuiderzee (Southern Sea) was the main transport route from Amsterdam to the North Sea and the Hanseatic L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Discharge (hydrology)
In hydrology, discharge is the volumetric flow rate (volume per time, in units of m3/h or ft3/h) of a stream. It equals the product of average flow velocity (with dimension of length per time, in m/h or ft/h) and the cross-sectional area (in m2 or ft2). It includes any suspended solids (e.g. sediment), dissolved chemicals like (aq), or biologic material (e.g. diatoms) in addition to the water itself. Terms may vary between disciplines. For example, a fluvial hydrologist studying natural river systems may define discharge as streamflow, whereas an engineer operating a reservoir system may equate it with outflow, contrasted with inflow. Formulation A discharge is a measure of the quantity of any fluid flow over unit time. The quantity may be either volume or mass. Thus the water discharge of a tap (faucet) can be measured with a measuring jug and a stopwatch. Here the discharge might be 1 litre per 15 seconds, equivalent to 67 ml/second or 4 litres/minute. This is an average meas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dutch Guilder
The guilder (, ) or florin was the currency of the Netherlands from 1434 until 2002, when it was replaced by the euro. The Dutch name was a Middle Dutch adjective meaning 'golden', and reflects the fact that, when first introduced in 1434, its value was about equal to (i.e., it was on par with) the Italian gold florin. The Dutch guilder was a reserve currency in Europe in the 17th and 18th centuries. Between 1999 and 2002, the guilder was officially a "national subunit" of the euro. However, physical payments could only be made in guilders, as no euro coins or banknotes were available. The exact exchange rate, still relevant for old contracts and for exchange of the old currency for euros at the central bank, is exactly 2.20371 Dutch guilders for 1 euro. Inverted, this gives approximately 0.453780 euros for 1 guilder. Derived from the Dutch guilder are the Netherlands Antillean guilder (still in use in Curaçao and Sint Maarten) and the Surinamese guilder (replaced in 20 ...

Juliana Of The Netherlands
Juliana (; Juliana Louise Emma Marie Wilhelmina; 30 April 1909 – 20 March 2004) was Queen of the Netherlands from 1948 until her abdication in 1980. Juliana was the only child of Queen Wilhelmina and Duke Henry of Mecklenburg-Schwerin. She received a private education and studied international law at the University of Leiden. In 1937, she married Prince Bernhard of Lippe-Biesterfeld with whom she had four daughters: Beatrix, Irene, Margriet, and Christina. During the German invasion of the Netherlands in the Second World War, the royal family was evacuated to the United Kingdom. Juliana then relocated to Canada with her children, while Wilhelmina and Bernhard remained in Britain. The royal family returned to the Netherlands after its liberation in 1945. Due to Wilhelmina's failing health, Juliana took over royal duties briefly in 1947 and 1948. In September 1948, Wilhelmina abdicated and Juliana ascended to the Dutch throne. Her reign saw the decolonization and indepen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marshall Plan
The Marshall Plan (officially the European Recovery Program, ERP) was an American initiative enacted in 1948 to provide foreign aid to Western Europe. The United States transferred $13.3 billion (equivalent to $ in ) in economic recovery programs to Western European economies after the end of World War II in Europe. Replacing an earlier proposal for a Morgenthau Plan, it operated for four years beginning on April 3, 1948, though in 1951, the Marshall Plan was largely replaced by the Mutual Security Act. The goals of the United States were to rebuild war-torn regions, remove trade barriers, modernize Manufacturing, industry, improve European prosperity and prevent the spread of communism. The Marshall Plan proposed the reduction of interstate barriers and the economic integration of the Europe, European Continent while also encouraging an increase in productivity as well as the adoption of modern business procedures. The Marshall Plan aid was divided among the participant sta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deep Foundation
A pile or piling is a vertical structural element of a deep foundation, driven or drilled deep into the ground at the building site. A deep foundation is a type of foundation (architecture), foundation that transfers building loads to the earth farther down from the surface than a shallow foundation does to a subsurface layer or a range of depths. There are many reasons that a geotechnical engineer would recommend a deep foundation over a shallow foundation, such as for a skyscraper. Some of the common reasons are very large design loads, a poor soil at shallow depth, or site constraints like property lines. There are different terms used to describe different types of deep foundations including the pile (which is analogous to a pole), the pier (which is analogous to a column), drilled shafts, and Caisson (engineering), caissons. Piles are generally driven into the ground ''in situ''; other deep foundations are typically put in place using excavation and drilling. The namin ...

Koningin Juliana Stelt Het Gemaal In Werking, Bestanddeelnr 908-0009
This is a list of monarchs of the Netherlands (Dutch: ''Koningen der Nederlanden''). By practical extension, the list includes the stadtholders of the House of Orange Nassau since 1556. However, they were voted into office by, and were civil servants and generals of, the semi-independent provinces of the Dutch Republic and cannot be seen as monarchs. From William IV they were the direct male line ancestors of later monarchs when the monarchy was established in 1813 (first as a Sovereign Principality, but in 1815 as a Kingdom). Dutch Republic (1581–1795) The origin of the Dutch monarchy can be traced back to the appointment of William I, Prince of Orange as stadtholder of Holland, Zeeland and Utrecht in 1559 by Philip II of Spain. However, he was removed from office and became the leader of the Dutch Revolt. Consequently, the States-General appointed him as stadtholder of both rebelling provinces, Holland and Zeeland, in 1572. During the Dutch Revolt, most of the Dutch provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polder
A polder () is a low-lying tract of land that forms an artificial hydrology, hydrological entity, enclosed by embankments known as levee, dikes. The three types of polder are: # Land reclamation, Land reclaimed from a body of water, such as a lake or the seabed # Floodplain, Flood plains separated from the sea or river by a dike # Marshes separated from the surrounding water by a dike and subsequently drained; these are also known as ''koogs'', especially in Germany The ground level in drained marshes subsidence, subsides over time. All polders will eventually be below the surrounding water level some or all of the time. Water enters the low-lying polder through infiltration (hydrology), infiltration and water pressure of groundwater, or rainfall, or transport of water by rivers and canals. This usually means that the polder has an excess of water, which is pumped out or drained by opening sluices at low tide. Care must be taken not to set the internal water level too low. Pold ...

Check Valve
A check valve, non-return valve, reflux valve, retention valve, foot valve, or one-way valve is a valve that normally allows fluid (liquid or gas) to flow through it in only one direction. Check valves are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave. There are various types of check valves used in a wide variety of applications. Check valves are often part of common household items. Although they are available in a wide range of sizes and costs, check valves generally are very small, simple, and inexpensive. Check valves work automatically and most are not controlled by a person or any external control; accordingly, most do not have any valve handle or stem. The bodies (external shells) of most check valves are made of plastic or metal. An important concept in check valves is the cracking pressure which is the minimum differential upstream pressure between inlet and outlet at which the valve will operate ...

Hendrik Wortman
Hendrik Wortman (25 March 1859 – 21 October 1939) was a Dutch civil engineer. Born in Amersfoort, Utrecht, he graduated from Delft Polytechnic in 1880 and joined the Rijkswaterstaat. He took offices throughout the country, focusing particularly on questions of water management and hydraulic engineering, until he was seconded to the Ministry of Public Works, Trade, and Industry in 1894. In this capacity, he developed several infrastructure projects, including a harbour in Scheveningen, while preparing exploratory studies for damming of the Zuiderzee. After Queen Wilhelmina of the Netherlands gave royal assent to the Zuiderzee Works, in 1919 Wortman was appointed as the director general of the Zuiderzee Works Service. Wortman thus designed several aspects of the project as he oversaw its initial stages, including early work on the Afsluitdijk. For his contributions, Wortman was appointed to the Orders of the Netherlands Lion and Orange-Nassau. The H. Wortman Pumping ...
