Stormvloedkering Hollandse IJssel
The ( English: ''Hollandse IJssel Storm Surge Barrier''), (''Hollandse IJssel Barrier'') or (''Algera Barrier'') is a storm surge barrier located on the Hollandse IJssel, at the municipal boundary of Capelle aan den IJssel and Krimpen aan den IJssel, east of Rotterdam in The Netherlands. The construction of the works comprised the first project of the Delta Works, undertaken in response to the disastrous effects of the North Sea flood of 1953. Prior to 1954, the spelling was used in the official name. The Hollandse IJssel is a low-lying river, and during the 1953 flood, the river dikes were exposed to dangerously high water levels, placing around 1.5 million people in the Randstad at risk from flooding. A dike at Ouderkerk aan den IJssel failed, and a dike in Nieuwerkerk aan den IJssel was almost breached, being sealed only after the local mayor ordered sailor Arie Evegroen to navigate his barge into the hole which had been formed in it. The body in charge of the De ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hollandse IJssel
The Hollandse (or Hollandsche) IJssel (; "Holland IJssel", as opposed to the 'regular' or Gelderland IJssel) is a branch of the Rhine delta that flows westward from Nieuwegein on river Lek through IJsselstein, Gouda and Capelle aan den IJssel to Krimpen aan den IJssel, where it ends in the Nieuwe Maas. Another branch called Enge IJssel ("Narrow IJssel") flows southwest from Nieuwegein. The name IJssel is thought to derive from the Germanic ''i sala'', meaning "dark water". Originally, the Hollandse IJssel forked off from river Lek at Nieuwegein, but the connection was cut off with the Hollandse IJssel nowadays only draining the surrounding pastures. If the North Sea floods, the Hollandse IJssel allows water through the Rotterdam Waterway to flood low-lying land east of Rotterdam. The Delta Works included a steel barrier that can be lowered within minutes to block the waterway. The sea protection constructions were built at the mouth of the Hollandse IJssel in 1957. See al ...

Barge
Barge nowadays generally refers to a flat-bottomed inland waterway vessel which does not have its own means of mechanical propulsion. The first modern barges were pulled by tugs, but nowadays most are pushed by pusher boats, or other vessels. The term barge has a rich history, and therefore there are many other types of barges. History of the barge Etymology "Barge" is attested from 1300, from Old French ''barge'', from Vulgar Latin ''barga''. The word originally could refer to any small boat; the modern meaning arose around 1480. ''Bark'' "small ship" is attested from 1420, from Old French ''barque'', from Vulgar Latin ''barca'' (400 AD). The more precise meaning of Barque as "three-masted sailing vessel" arose in the 17th century, and often takes the French spelling for disambiguation. Both are probably derived from the Latin ''barica'', from Greek ''baris'' "Egyptian boat", from Coptic ''bari'' "small boat", hieroglyphic Egyptian D58-G29-M17-M17-D21-P1 and similar ' ...

Control Lock
A control lock, guard lock or Lock_(water_transport)#Stop_locks, stop lock differs from a normal canal lock in that its primary purpose is controlling variances in water level rather than raising or lowering vessels. A control lock may also be known as a tide lock where it is used to control seawater entering into a body of fresh water. Examples The T. J. O’Brien Lock and Dam at Chicago, Illinois is a guard lock that controls the outflow of water from Lake Michigan into the Illinois Waterway while locking vessels through between the waterway and Lake Michigan. Lock 8 near the south end of the Welland Canal at Port Colborne, Ontario, Canada is a guard lock. Due to the large expanse of shallow water in Lake Erie, changes in wind direction and force create water level changes as great as 11 feet (3.4 m) at Port Colborne. Lock 8 controls the water level in the canal, keeping it independent of the fluctuations of Lake Erie, but allows ships to enter Lake Erie regardless of its level. ...

Polders
A polder () is a low-lying tract of land that forms an artificial hydrological entity, enclosed by embankments known as dikes. The three types of polder are: # Land reclaimed from a body of water, such as a lake or the seabed # 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 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 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. Polder land made up of peat (former marshland) will sink in relation to its previo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seawater
Seawater, or salt water, is water from a sea or ocean. On average, seawater in the world's oceans has a salinity of about 3.5% (35 g/L, 35 ppt, 600 mM). This means that every kilogram (roughly one liter by volume) of seawater has approximately of dissolved salts (predominantly sodium () and chloride () ions). The average density at the surface is 1.025 kg/L. Seawater is denser than both fresh water and pure water (density 1.0 kg/L at ) because the dissolved salts increase the mass by a larger proportion than the volume. The freezing point of seawater decreases as salt concentration increases. At typical salinity, it freezes at about . The coldest seawater still in the liquid state ever recorded was found in 2010, in a stream under an Antarctic glacier: the measured temperature was . Seawater pH is typically limited to a range between 7.5 and 8.4. However, there is no universally accepted reference pH-scale for seawater and the difference between measu ...

South Holland
South Holland ( nl, Zuid-Holland ) is a province of the Netherlands with a population of over 3.7 million as of October 2021 and a population density of about , making it the country's most populous province and one of the world's most densely populated areas. Situated on the North Sea in the west of the Netherlands, South Holland covers an area of , of which is water. It borders North Holland to the north, Utrecht and Gelderland to the east, and North Brabant and Zeeland to the south. The provincial capital is the Dutch seat of government The Hague, while its largest city is Rotterdam. The Rhine-Meuse-Scheldt delta drains through South Holland into the North Sea. Europe's busiest seaport, the Port of Rotterdam, is located in South Holland. History Early history Archaeological discoveries in Hardinxveld-Giessendam indicate that the area of South Holland has been inhabited since at least c. 7,500 years before present, probably by nomadic hunter-gatherers.

Drinking Water
Drinking water is water that is used in drink or food preparation; potable water is water that is safe to be used as drinking water. The amount of drinking water required to maintain good health varies, and depends on physical activity level, age, health-related issues, and environmental conditions. This 2004 article focuses on the USA context and uses data collected from the US military. Recent work showed that the most important driver of water turnover which is closely linked to water requirements is energy expenditure. For those who work in a hot climate, up to a day may be required. Typically in developed countries, tap water meets drinking water quality standards, even though only a small proportion is actually consumed or used in food preparation. Other typical uses for tap water include washing, toilets, and irrigation. Greywater may also be used for toilets or irrigation. Its use for irrigation however may be associated with risks. Water may also be unacceptable d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maritime Transport
Maritime transport (or ocean transport) and hydraulic effluvial transport, or more generally waterborne transport, is the transport of people ( passengers) or goods ( cargo) via waterways. Freight transport by sea has been widely used throughout recorded history. The advent of aviation has diminished the importance of sea travel for passengers, though it is still popular for short trips and pleasure cruises. Transport by water is cheaper than transport by air, despite fluctuating exchange rates and a fee placed on top of freighting charges for carrier companies known as the currency adjustment factor. Maritime transport accounts for roughly 80% of international trade, according to UNCTAD in 2020. Maritime transport can be realized over any distance by boat, ship, sailboat or barge, over oceans and lakes, through canals or along rivers. Shipping may be for commerce, recreation, or military purposes. While extensive inland shipping is less critical today, the majo ...

Navigational Aid
Navigation is a field of study that focuses on the process of monitoring and controlling the movement of a craft or vehicle from one place to another.Bowditch, 2003:799. The field of navigation includes four general categories: land navigation, marine navigation, aeronautic navigation, and space navigation. It is also the term of art used for the specialized knowledge used by navigators to perform navigation tasks. All navigational techniques involve locating the navigator's position compared to known locations or patterns. Navigation, in a broader sense, can refer to any skill or study that involves the determination of position and direction. In this sense, navigation includes orienteering and pedestrian navigation. History In the European medieval period, navigation was considered part of the set of '' seven mechanical arts'', none of which were used for long voyages across open ocean. Polynesian navigation is probably the earliest form of open-ocean navigation; it was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rijksmonument
A rijksmonument (, ) is a national heritage site of the Netherlands, listed by the agency Rijksdienst voor het Cultureel Erfgoed (RCE) acting for the Dutch Ministry of Education, Culture and Science. At the end of February 2015, the Netherlands had 61,822 listed national heritage sites, of which approximately 1,500 are listed as archaeological sites. History and criteria Until 2012, a place had to be over 50 years old to be eligible for designation. This criterion expired on 1 January 2012. The current legislation governing the monuments is the ''Monumentenwet van 1988'' ("Monument Law of 1988"). The organization responsible for caring for the monuments, which used to be called ''Monumentenzorg'', was recently renamed, and is now called Rijksdienst voor het Cultureel Erfgoed. In June 2009, the Court of The Hague decided that individual purchasers of buildings that were listed as rijksmonuments would be exempt from paying transfer tax, effective from 1 May 2009.
