Flood barriers on the Thames River.
....at a cost of some $8 billion over a quarter century, (the Netherlands) erected a futuristic system of coastal defenses that is admired around the world today as one of the best barriers against the sea's fury - one that could withstand the kind of storm that happens only once in 10,000 years.
