Only in America. The Delta Works in the Netherlands are designed for the 2000-year flood. This is the minimum - there are areas that are protected against the 10000-year flood.
This makes sense. It is not normal that densely settled areas are flooded at least once during the human lifespan.

- arethuza 14y agoIn the context of a 10000-year flood, it's interesting to consider what the southern North Sea looked like until ~6200 BCE: http://en.wikipedia.org/wiki/Doggerland http://en.wikipedia.org/wiki/Doggerland
- youngerdryas 14y ago>Only in America. You don't seriously claim all of Europe is prepared for a 2000 year flood. I doubt a lot of nations can afford it.
- HarryHirsch 14y agoSouth Holland is, and it has 4 million people living in it.
- youngerdryas 14y agoI was thinking more of Italy and its notorious construction fiascos.
