De Hef
De Hef (), officially Koningshaven Bridge, is a vertical-lift bridge over the Koningshaven (Kings Harbor) channel at the port of Rotterdam, Netherlands. Built in 1927, the bridge was part of the Breda–Rotterdam railway line until it was decommissioned in 1993. Today, it is a Rijksmonument heritage site. History The predecessor bridge dated from 1878. Its configuration as a swing bridge proved an obstacle to shipping (the most notable incident occurring in 1918, when the bridge was struck by the German vessel ''Kandelfels''), and it was replaced by a lift bridge in 1927. It was the first bridge of this kind in western Europe. The bridge was the subject of a 1928 film by Joris Ivens, titled '' De brug''. Redevelopment Plans to demolish the railway line and bridge in 1993 were abandoned after widespread protests from local residents. The line was removed but the bridge was left in place as a Rijksmonument national heritage monument. In November 2014, the disused bridge' ...

Vertical-lift Bridge
A vertical-lift bridge or just lift bridge is a type of movable bridge in which a span rises vertically while remaining parallel with the deck. The vertical lift offers several benefits over other movable bridges such as the bascule and swing-span bridges. Generally speaking, they cost less to build for longer moveable spans. The counterweights in a vertical lift are only required to be equal to the weight of the deck, whereas bascule bridge counterweights must weigh several times as much as the span being lifted. As a result, heavier materials can be used in the deck, and so this type of bridge is especially suited for heavy railroad use. The biggest disadvantage to the vertical-lift bridge (in comparison with many other designs) is the height restriction for vessels passing under it, due to the deck remaining suspended above the passageway. Although most vertical-lift bridges use towers, each equipped with counterweights, some use hydraulic jacks located below the deck. ...

Channel (geography)
In physical geography, a channel is a type of landform consisting of the outline of a path of relatively shallow and narrow body of water or of other fluids (e.g., lava), most commonly the confine of a river, river delta or strait. The word is cognate to canal, and sometimes takes this form, e.g. the Hood Canal. Formation Channel initiation refers to the site on a mountain slope where water begins to flow between identifiable banks.Bierman, R. B, David R. Montgomery (2014). Key Concepts in Geomorphology. W. H. Freeman and Company Publishers. United States. This site is referred to as the channel head and it marks an important boundary between hillslope processes and fluvial processes. The channel head is the most upslope part of a channel network and is defined by flowing water between defined identifiable banks. A channel head forms as overland flow and/or subsurface flow accumulate to a point where shear stress can overcome erosion resistance of the ground surface. Channel he ...

Rotterdam
Rotterdam ( , , , lit. ''The Dam on the River Rotte'') is the second largest city and municipality in the Netherlands. It is in the province of South Holland, part of the North Sea mouth of the Rhine–Meuse–Scheldt delta, via the ''"New Meuse"'' inland shipping channel, dug to connect to the Meuse first, but now to the Rhine instead. Rotterdam's history goes back to 1270, when a dam was constructed in the Rotte. In 1340, Rotterdam was granted city rights by William IV, Count of Holland. The Rotterdam–The Hague metropolitan area, with a population of approximately 2.7 million, is the 10th-largest in the European Union and the most populous in the country. A major logistic and economic centre, Rotterdam is Europe's largest seaport. In 2020, it had a population of 651,446 and is home to over 180 nationalities. Rotterdam is known for its university, riverside setting, lively cultural life, maritime heritage and modern architecture. The near-complete destruction ...

Breda–Rotterdam Railway
The Breda–Rotterdam railway is a heavily used railway line in the Netherlands running from Breda to Rotterdam, passing through Dordrecht. It is also called the ''Staatslijn I'' ("state line I") in Dutch. The line was opened between 1866 and 1877. The railway was opened in phases: * 1 July 1866: - - * 1 January 1872: Lage Zwaluwe - Dordrecht, including the Moerdijk Bridge * 1 November 1872: - Rotterdam Mallegat * 1 May 1877: Rotterdam Mallegat - * 2 December 1878: Rotterdam Mallegat - Rotterdam Feijenoord (goods transport only) Until 1872, transport between Moerdijk and Rotterdam was by ferry. The railway was electrified in 1950. With the opening of the in 1994, the through the centre of Rotterdam became redundant. The railway viaducts and the old over the Nieuwe Maas were subsequently demolished, leaving only the lifting bridge De Hef over the Koningshaven which has been preserved as an industrial heritage site. Stations The main interchange stations on the Bredaâ ...

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.

Swing Bridge
A swing bridge (or swing span bridge) is a movable bridge that has as its primary structural support a vertical locating pin and support ring, usually at or near to its center of gravity, about which the swing span (turning span) can then pivot horizontally as shown in the animated illustration to the right. Small swing bridges as found over canals may be pivoted only at one end, opening as would a gate, but require substantial underground structure to support the pivot. In its closed position, a swing bridge carrying a road or railway over a river or canal, for example, allows traffic to cross. When a water vessel needs to pass the bridge, road traffic is stopped (usually by traffic signals and barriers), and then motors rotate the bridge horizontally about its pivot point. The typical swing bridge will rotate approximately 90 degrees, or one-quarter turn; however, a bridge which intersects the navigation channel at an oblique angle may be built to rotate only 45 degrees, or ...

Joris Ivens
Georg Henri Anton "Joris" Ivens (18 November 1898 – 28 June 1989) was a Dutch documentary filmmaker. Among the notable films he directed or co-directed are '' A Tale of the Wind'', '' The Spanish Earth'', ''Rain'', ''...A Valparaiso'', ''Misère au Borinage'' (''Borinage''), '' 17th Parallel: Vietnam in War'', ''The Seine Meets Paris'', '' Far from Vietnam'', ''Pour le Mistral'' and ''How Yukong Moved the Mountains''. Early life and career Born Georg Henri Anton Ivens into a wealthy family, Ivens went to work in one of his father's photo supply shops and from there developed an interest in film. Under the direction of his father, he completed his first film at 13; in college he studied economics with the goal of continuing his father's business, but an interest in class issues distracted him from that path. He met photographer Germaine Krull in Berlin in 1923, and entered into a marriage of convenience with her between 1927 and 1943 so that Krull could hold a Dutch passport ...

It is in the province of South Holland, part of the North Sea mouth of the Rhine–Meuse–Scheldt delta, via the ''"N ..., a vertical-lift railroad bridge. The film looks at its structure, mechanisms, complex actions, and the steam-powered trains and ships making use of it. Synopsis Three views of the film camera appear "as if in a technical drawing. It then proceeds to examine the bridge from all angles." The bridge is shown in ultrawide format, then wide, then in close-up, from a train rider's viewpoint. The view shifts to outside the train looking down at the harbor water far below, then to clouds of steam obscuring and revealing the bridge's steel structure. A ...

Y721
''Koru'' is a luxury custom superyacht owned by Jeff Bezos, the founder of Amazon. The vessel was built in the Netherlands by Oceanco starting in 2021, and delivered in April 2023. It is a three-masted sailing yacht long and reported to have cost $500 million or more. When commissioned, the yacht was the second-largest sailing yacht in the world, after Andrey Melnichenko's Sailing Yacht ''A''. ''Koru'' and De Hef In 2022, Rotterdam announced that the city's historic De Hef bridge would be partially dismantled, temporarily, to allow the yacht to pass through. This move was very controversial because the bridge is a Dutch national monument owing to its long history. In the end, the partial dismantling of the 'De Hef' bridge proved to be unnecessary. The masts were stepped when the vessel was downstream of the bridge in the Rotterdam Harbour. Support vessel A 1,900 Gross ton yacht support vessel, the ''Abeona'', will "shadow" ''Koru'', providing additional crew accommoda ...
