So, last week, I wrote about the\u00a0Zuiderzeewerken<\/a><\/em>, which gave birth to the province Flevoland. But not only that.<\/p>\n

\"As<\/a>

As you can see, the Afsluitdijk was finished in 1932, after which there was space for the creation of Flevoland. (Image by Io Herodotus at Commons.wikipedia.org)<\/p><\/div>\n

The\u00a0Zuiderzeewerken<\/em>\u00a0had as their goal to create more land for agricultural use, and to “tame” the\u00a0Zuiderzee<\/em>, the part of the\u00a0Noordzee\u00a0<\/em>(North Sea) that protruded well into the Dutch inland. Another goal, which was pursued already centuries before the proposal of the\u00a0Zuiderzeewerken\u00a0<\/em>at the end of the 1800s, was to stop the frequent floods and devastation the\u00a0Zuiderzee\u00a0<\/em>would cause through its influence of the Noordzee<\/em>.<\/p>\n

The Dutch wanted to regulate this better. And one of the first, and probably the most important way to do this was the\u00a0Afsluitdijk<\/em>.\u00a0The name literally means the “Lock Dyke”, since it locks up the Zuiderzee<\/i>, away from its parent, the\u00a0Noordzee<\/em>. The name\u00a0dijk\u00a0<\/em>is not entirely accurate – a\u00a0dijk\u00a0<\/em>refers to a separation between water and land, whereas the\u00a0Afsluitdijk\u00a0<\/em>separates two waters – making it a\u00a0dam<\/em>. The accurate name would therefore be\u00a0Afsluitdam<\/em>!<\/p>\n

Whatever its name, the 32 km (almost 20 mi) long road on the\u00a0dam, which itself is actually 30 km (almost\u00a019 mi) long. This closure was built from 1927-1932: a remarkable feat for its time! So the question that comes up, of course, is:<\/p>\n

How did they do it?<\/strong><\/p>\n

First, in 1920, the Amsteldiepdijk\u00a0<\/i>or\u00a0Korte Afsluitdijk\u00a0<\/em>was built, which served as a model and try-out for the real deal. This\u00a0dijk<\/em> was only 2.5 km (1.5 mi) long, and was connected\u00a0Noord-Holland\u00a0<\/em>to the island\u00a0Wieringen<\/em>. The experience made in this short project was later used in the construction of the\u00a0Afsluitdijk<\/em>.<\/p>\n

That construction started in 1927. The\u00a0Afsluitdijk\u00a0<\/em>was built from four locations: from the coastal line in Noord-Holland at\u00a0Den Oever<\/em>, from the coastal line in Friesland at\u00a0Zurich<\/em>, from\u00a0Breezand<\/em>, and from\u00a0Kornwederzand<\/em>.\u00a0Breezand\u00a0<\/em>and\u00a0Kornwederzand\u00a0<\/em>were both\u00a0werkeilanden\u00a0<\/em>(work islands), which were built on the track of the Afsluitdijk.\u00a0<\/i><\/p>\n

As a foundation,\u00a0wilgtenen\u00a0<\/em>were used – willow rods. These were sunk by placing stone blocks on top of them. Now I bet you think: wood? How is that supposed to withstand all that water force for decades? Well, it didn’t. Already in 1931, it became clear that the wood was infected with paalworm<\/i>, a parasite that makes the wood hollow, and the steel rods that kept the wood together was already strongly affected by the sea. German\u00a0baryte was used as a replacement, a strong mineral that withstands water very well.<\/p>\n

Keileem\u00a0<\/em>(boulder clay) was used for the first time in the\u00a0Afsluitdijk<\/em>, because it was deemed stronger than sand or clay. Together with sand and stones,\u00a0keileem\u00a0<\/em>formed the body of the dijk<\/em>.<\/p>\n

Two, and later three,\u00a0sluizen\u00a0<\/em>(locks) were inserted into the\u00a0dijk<\/em> to regulate the water in the\u00a0IJsselmeer<\/em>, since rivers would still increase the amount of water in it.<\/p>\n

On this dijk<\/i>, a road was built, and that basically completed the work in 1932. On \u00a0September 20 of that year, the\u00a0Zuiderzee\u00a0<\/em>officially became the\u00a0IJsselmeer<\/em>.<\/p>\n

Success<\/b><\/p>\n

The first noticeable success of the Afsluitdijk\u00a0<\/em>was in 1953, when the\u00a0Watersnoodramp\u00a0<\/em>struck. It withstood the high water, and saved a lot of lives and disaster around the IJsselmeer<\/em>.<\/p>\n

Criticism<\/strong><\/p>\n

Back in the days of its construction, fishermen were complaining, because the fishery in the Zuiderzee\u00a0<\/i>would end with the\u00a0Afsluitdijk<\/em>. However, their protest was not enough, and it was built anyway. A small poem was left, that described this:<\/p>\n

Eerst de zee en nu de netten <\/em>
\nnam men van de Urkers af <\/em>
\nEn zoo delft men, schop voor schopje <\/em>
\nlangzaam aan des visschers graf.<\/em><\/p>\n

Do you understand what it says? Let me know in the comments!<\/p>\n

Visiting the\u00a0Afsluitdijk<\/em><\/strong><\/p>\n

You can also visit the\u00a0Afsluitdijk<\/em>, climb the uitkijktoren\u00a0<\/em>(observation tower)\u00a0and see the dam from up high, and take nice pictures like the one above. This\u00a0Monument op de Afsluitdijk\u00a0<\/em>was built in 1933 at the\u00a0Vlieter<\/em>, where the\u00a0Afsluitdijk\u00a0<\/i>was closed in 1932.<\/p>\n

Have you been to the Afsluitdijk before?<\/p>\n

Are there similar spectacular constructions in your country?<\/p>\n
