The Maatschappij tot Uitvoering van Zuiderzeewerken (MUZ) ( English: Society for the Execution of the Zuiderzee Works) was a consortium of dredging contractors in the Netherlands, formed in August 1926 for the specific purpose of executing the Zuiderzee Works. The Zuiderzee Works comprised a number of significant hydraulic engineering projects designed to dam the Zuiderzee, a large shallow inlet of the North Sea, to prevent flooding and reclaim land for agricultural and residential use.
The founding companies of the consortium included M.J. van Hattum's Havenwerken from Beverwijk, Hollandsche Aannemingsmaatschappij from The Hague, A. Bos from Dordrecht, and L. Volker.
MUZ was headquartered in Den Oever and was responsible for the construction of several key projects of the Zuiderzee Works, including the Afsluitdijk, a major dam and causeway completed in 1932 that converted the Zuiderzee into the freshwater IJsselmeer. The work carried out by the MUZ consortium significantly influenced water management and contracting practices in the Netherlands, but the lack of competition for major infrastructure projects arising from the creation of such a large entity attracted criticism. [1] [2]
The consortium was led by J.A. Ringers, an engineer previously employed by Rijkswaterstaat whose hydraulic engineering experience included overseeing the construction of the Noordersluis at IJmuiden. Whilst Ringers' involvement provided significant technical expertise and governmental trust, there remained some concerns that awarding a series of large infrastructure projects to a single joint venture entity created an effective monopoly. [1] [3] These concerns were partially assuaged by the formation of a rival consortium in 1927, known as Maatschappij tot Aanneming van Zuiderzeewerken (MAZ)(English: Society for Contracting Zuiderzee Works). [4]
The first project undertaken by the MUZ was the construction of the Pilot Polder at Andijk (Dutch: Proefpolder Andijk). On 17 September 1927, a competitor organisation known as the Society for Contracting Zuiderzee Works (Dutch:Maatschappij tot Aanneming van Zuiderzeewerken, MAZ) was founded. The MAZ was established by N.V. Maatschappij tot Aanneming van Werken, owned by A.L.J. (Leendert) Volker of Bussum, and Johannes Kraaijeveld of Sliedrecht, with the company later becoming Boskalis. [3] This consortium was based in Anna Paulowna, with its first project being the construction of a dike around the Boezemmeer south of Wieringen. [5]
Over time, additional contractors joined the MAZ joint venture, including A. Prins and K.L. Kalis. Several companies from outside the two joint venture groups, such as Breejenbout and Zanen Verstoep, participated in the Zuiderzee Works through special arrangements. [1]
During the Great Depression, economic challenges necessitated increased collaboration within the Netherlands dredging industry. This led to the establishment of an association of Dutch dredging contractors known as the Vereniging “centraal baggerbedrijf”which ultimately facilitated the merger of the MUZ and MAZ organisations. Historical records indicate significant cultural differences between these two organisations, with the MUZ often described as more formal. [6] This perception is noted in an appendix to the 2001 reissue of the book Het verjaagde water, which includes a historical account of events undertaken by researchers from Delft University of Technology.

The Zuiderzee Works is a system of dams and dikes, land reclamation and water drainage work, which was the largest hydraulic engineering project undertaken by the Netherlands during the twentieth century. The project involved the damming of the Zuiderzee, a large, shallow inlet of the North Sea, and the reclamation of land in the newly enclosed water using polders. Its main purposes are to improve flood protection and create additional land for agriculture.
The Afsluitdijk 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 32 kilometres (20 mi) and a width of 90 metres (300 ft), at an initial height above Amsterdam Ordnance Datum of between 6.7 metres (22 ft) along the section at Friesland, and 7.4 metres (24 ft) where it crosses the deep channel of the Vlieter. The height at the greater sea depths west of Friesland was required to be a minimum of 7 metres everywhere when originally constructed.
The Oosterscheldekering, between the islands Schouwen-Duiveland and Noord-Beveland, is the largest of the Delta Works, a series of dams and storm surge barriers, designed to protect the Netherlands from flooding from the North Sea. The construction of the Delta Works was a response to the widespread damage and loss of life in the North Sea flood of 1953.
Flood control is an important issue for the Netherlands, as due to its low elevation, approximately two thirds of its area is vulnerable to flooding, while the country is densely populated. Natural sand dunes and constructed dikes, dams, and floodgates provide defense against storm surges from the sea. River dikes prevent flooding from water flowing into the country by the major rivers Rhine and Meuse, while a complicated system of drainage ditches, canals, and pumping stations keep the low-lying parts dry for habitation and agriculture. Water control boards are the independent local government bodies responsible for maintaining this system.
The Deltar was an analogue computer used in the design and execution of the Delta Works from 1960 to 1984. Originated by Johan van Veen, who also built the initial prototypes between 1944 and 1946, its development was continued by J.C. Schönfeld and C.M. Verhagen after van Veen's death in 1959.
Johannes Aleidis (Johan) Ringers was a Dutch hydraulic engineer and politician. He served as the director-general of Rijkswaterstaat and later as the director of Dutch East Indies Railways. During World War II, Ringers was appointed as the government commissioner for reconstruction, but was later interned by German forces.
A. den Doolaard is the pseudonym of the Dutch writer and journalist Cornelis Johannes George (Bob) Spoelstra Jr.
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.
Land reclamation in the Netherlands has a long history. As early as in the 14th century, the first reclaimed land had been settled. Much of the modern land reclamation has been done as a part of the Zuiderzee Works since 1919.
Elizabeth Frederika van den Ban, known as Elze, was a Dutch urban planner and chief engineer of the Rijkswaterstaat at Zuiderzee Works where she introduced curvatures rather than straight lines into the urban planning process of polders and dikes. Van den Ban was the first woman from the Netherlands to graduate as a civil engineer in Delft, where she worked as a civil engineer.
Het verjaagde water is a 1947 Dutch non-fiction novel written by A. den Doolaard, which gives an account of the recovery works to repair dike breaches after the October 1944 Inundation of Walcheren as part of operations by The Allies of World War II during Operation Infatuate. Researchers from Delft University of Technology have found high levels of historical accuracy in den Doolaard's descriptions of the events that took place, the methods used to close the dikes and the key people involved. Den Doolaard assigned pseudonyms to most of the main characters and organisations. The name A. den Doolaard is also a pseudonym, the author’s real name being Cornelis Johannes George Spoelstra Jr.
The Stormvloedkering Hollandse IJssel, Hollandse IJsselkering or Algerakering 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 Hollandsche was used in the official name.
The Zandkreekdam is a compartmentalisation dam located approximately 3 kilometres north of the city of Goes in The Netherlands, which connects Zuid-Beveland with Noord-Beveland, and separates the Oosterschelde from the Veerse Meer.
Jo Johannis Dronkers was a Dutch mathematician who is notable for the development of mathematical methods for the calculation of tides and tidal currents in estuaries. His work formed much of the mathematical basis for the design of the Delta Works. He attended the 1954 International Congress of Mathematicians in Amsterdam, where his work was discussed by David van Dantzig.
Johannes Theodoor Thijsse was a Dutch hydraulic engineer who made significant contributions to hydraulic engineering both in The Netherlands and internationally. In addition to having a major involvement in the design and planning of both the Zuiderzee Works and the Delta Works, he published widely and played a key role in the establishment of the IHE Delft Institute for Water Education.
The Waterloopkundig Laboratorium was an independent Dutch scientific institute specialising in hydraulics and hydraulic engineering. The laboratory was established in Delft from 1927, moving to a new location in the city in 1973. The institute later became known as WL | Delft Hydraulics. In 2008, the laboratory was incorporated into the international nonprofit Deltares institute.
Pieter Philippus Jansen was a Dutch civil engineer and hydraulic engineer who made significant contributions to hydraulic engineering in The Netherlands. He spent the majority of his career with Rijkswaterstaat, working on several major projects including the first phase of the Delta Works and leading the reclamation and repair efforts following the inundation of Walcheren.
Jan Fokke Agema was a Dutch hydraulic engineer and professor at Delft University of Technology. He is notable for his design of the harbour entrance at Hoek van Holland and involvement in the construction of the Oosterscheldekering. The prof. dr.ir. J.F. Agemaprijs is named for him, and has been awarded every five years since 2000.
A fascine mattress(Dutch: Zinkstuk, literally sink piece), is a large woven mat made of brushwood, typically willow twigs and shoots, used to protect riverbeds and other underwater surfaces from scour and erosion. They are similar in construction to a fascine, but are primarily used for hydraulic engineering works, typically to strengthen the banks of rivers and streams, as well as coastal structures like revetments and groynes.
Deltares is a Groot Technologisch Instituut (GTI) in the Netherlands specialising in hydraulic engineering research and consulting, along with water management, geotechnics, and infrastructure.
