The Country That Should Be Underwater

A quarter of the Netherlands would be underwater by morning if the pumps stopped tonight. 17 million people live there anyway — on a drowned lake bed, under runways four metres below the sea, beside canals that run above the roads. It started with a night. On 31 January 1953, a spring tide and a hurricane arrived together and the dikes didn't overflow — they dissolved. 1,836 people died. Near Rotterdam, a barge captain steered his own ship into a splitting dike and plugged the breach with the hull, and three million people stayed dry because one boat sank in the right place. Twenty days later the Dutch government passed a single sentence into law: this can never happen again. What followed is the largest sustained engineering programme any country has ever run against the ocean — a 32 km dam that sealed an inland sea in one afternoon, a province pumped dry and colonised by wind-blown reed seed, concrete piers of 18,000 tons carried out to sea by a purpose-built ship, a storm barrier scrapped and redesigned because sealing the estuary was killing everything in it, and two steel arms heavier than the Eiffel Tower that close across Rotterdam with no human hand on the switch. Since 1953, the number of Dutch lives taken by a sea flood is zero.
