The second longest dam in the Delta Works, [1] after the 10.5-kilometre-long Oesterdam, [2] [3] [4] the nine-kilometre-long Oosterscheldekering (kering meaning barrier) was initially designed, and partly built, as a closed dam, but after public protests, [5] huge sluice-gate-type doors were installed in the remaining four kilometres.
After the North Sea flood of 1953, it was decided to close off the Oosterschelde by means of a dam and a storm surge barrier.The Oosterscheldekering (Eastern Scheldt Storm Surge Barrier), between Schouwen-Duiveland and Noord-Beveland, is the largest of 13 ambitious Delta Works designed to protect a large part of the Netherlands from flooding.
Zeeland Bridge Oosterscheldekering An important part of this project was fundamental research to come up with long-term solutions, protecting the Netherlands against future floods. Instead of analysing past floods and building protection sufficient to deal with those, the Delta Works commission pioneered a conceptual framework to use as norm ...
In 1974, it was decided by Rijkswaterstaat and the Den Uyl cabinet to construct the Oosterscheldekering as a storm surge barrier at the mouth of the Oosterschelde, instead of completely closing off the tidal inlet at that location. The construction of the Oosterscheldekering required the compartmentalisation of the basin. [2]
In 1976, under pressures from environmental groups and the fishing industry, it was decided not to close off the Oosterschelde estuary by a solid dam but instead to build the Oosterscheldekering, a storm surge barrier which is only closed during storms. It is the most well-known (and most expensive) dam of the project.
The innovative design of the dam, led by Spaargaren and involving other key hydraulic engineers such as Jan Agema, thus ensured the preservation of the saltwater marine ecosystem, enabled continued fishing activity, and provided flood control for the land beyond the dam. [6] [7] The Oosterscheldekering was successfully completed in 1986 and ...
