This article makes it seem as if protecting against rising water levels is an almost impossible feat. For everyone who thinks it is, I invite them to come to the Netherlands. The majority of the Netherlands lies under sea level, yet because it is completely protected by dikes/levees no floods have taken place for decades. In fact, all places that indexed by direct economical damage were a flood to take place; and get protected accordingly. A highly populated area or industrious zone might get a rating that only a flood every 10.000 years is acceptable, while for some rural areas may get a rating that a flood every 300 years is acceptable. https://www.rijnland.net/downloads/floodcontrolrijnland-1-1....
I wonder what rating Dutch dike safety experts would give to the NASA launch platform, but seeing such an important economical site with hardly any protection against floods certainly boggles me.
