#12This seems to have been automatically translated from https://www.nu.nl/binnenland/6295147/maeslantkering-voor-het.... For example, "coupure" (https://en.wikipedia.org/wiki/Coupure) got translated as "denomination", which is not correct in this context :)

#14The Maeslantkering closed automatically for the first time since its completion in 1998.
It had never been necessary before?

I find the emphasis on the automatic decision making and operation here interesting. Why does it need to be automatic?
Is it to relieve political pressure on the decision- makers, since closing the barrier prevents traffic in and out of Rotterdam?
Or is it because the algorithm is so complex and it has to anticipate water flow from the Rhine?

#16With the present conslusion from climate change models on how the water
will rise due to increased temperature, is not parts of the Netherlands
no longer viable and people and business will have ot move to regions
with higher elevation?
Should such a drastic move be taking place now, before the model conclusion say it will be underwater?
That based on the fact that the 1,5C goal has long since become untenable without drastic action, which is presently not taking place. -

Exactly your first reason, the algorithm is not complex but politics and economics would make it a hard decision for a human.

Do you expect resettling all Dutch abroad to be viable?
A substantial part of the Netherlands is already below sea level, even without climate change. Half of the country is less than a meter above.

#20The intesting part:
The flood defense closes automatically at a water level of 3 meters above NAP (Amsterdam water level baseline) at Rotterdam or 2.9 meters above NAP at Dordrecht. The two doors, each 210 meters wide and 22 meters high, fill with water when the barrier closes. They then sink to the bottom in about two hours. A computer system automatically determines whether the barrier should be closed. However, a team from Rikswaterstaat is present to supervise.
