From the perspective of an American living in the Netherlands for several years now...

The Dutch are light years ahead in their Water management from the US, and far ahead of any other developed nation. The Dutch have a separate tax for Water to ensure money is there to prioritize this need, the citizens/children are all educated on the importance of water management (i.e. Indoctrination from young so EVERY citizen knows how important it is).

Highly recommend everyone watch/read about the dam they built in the North Sea.

In short, they will be fine. This is a core part of their culture, investment, and priority.
