Rotterdam harbor storm barrier closes for the first time in its history

I read the article, and it says:<p>&gt; During the evening of 8 November 2007, the barrier was closed due to a storm surge for the first time.<p>I also read the archived reference article [0]:<p>&gt; In the Netherlands, maritime traffic in Rotterdam was halted as the authorities closed the giant Maeslant surge barrier, which guards the entrance to the largest port in Europe, for the first time since its construction in the 1990s<p>Is the title missing a [2007]? Or is there a current event happening as well that has been misidentified as the first occurrence of this?<p>* [0]: <a href="https:&#x2F;&#x2F;web.archive.org&#x2F;web&#x2F;20071109163913&#x2F;http:&#x2F;&#x2F;news.bbc.co.uk&#x2F;2&#x2F;hi&#x2F;europe&#x2F;7086175.stm" rel="nofollow noreferrer">https:&#x2F;&#x2F;web.archive.org&#x2F;web&#x2F;20071109163913&#x2F;http:&#x2F;&#x2F;news.bbc.c...</a>

The title of this is slightly inaccurate. It’s the first time the barrier has closed at its default 300cm surge level. It has previously closed for testing with the level set down to 280cm to test it in storm conditions.

Apparently the automated control system consists of 200,000 lines of formally-verified C++: <a href="https:&#x2F;&#x2F;ansymore.uantwerpen.be&#x2F;system&#x2F;files&#x2F;uploads&#x2F;courses&#x2F;SE3BAC&#x2F;p07_1_surgeBarrier.pdf" rel="nofollow noreferrer">https:&#x2F;&#x2F;ansymore.uantwerpen.be&#x2F;system&#x2F;files&#x2F;uploads&#x2F;courses&#x2F;...</a>

I always love saying that the Dutch coast is defended by a robot with arms the size of the Eiffel Tower.<p>It&#x27;s true! That&#x27;s how big those arms are, and it&#x27;s completely automated.

I love these kind of mega projects! Neat to see it in action.

Cool, but what does this mean?

FYI closing this gate has a huge economic impact and is left over to machines. The reasoning is a person living in the country would close this gate by fear of loosing families etc, here CODE decides when the time is right to close or stay open. It uses a lot of data to monitor and predict the weather.
