Dutch Katrina

The 1953 North Sea flood was a major flood caused by a heavy storm, that occurred on the night of Saturday, 31 January 1953 and morning of Sunday, 1 February 1953. The floods struck the Netherlands, Belgium, England and Scotland.

A combination of a high spring tide and a severe European windstorm over the North Sea caused a storm tide of the North Sea; the combination of wind, high tide, and low pressure led to a water level of more than 5.6 metres (18.4 ft) above mean sea level in some locations. The flood and waves overwhelmed sea defences and caused extensive flooding. The Netherlands, a country with 20% of its territory below mean sea level and 50% less than 1 metre (3.3 ft) above sea level and which relies heavily on sea defences, was worst affected, recording 1,836 deaths and widespread property damage. Most of the casualties occurred in the southern province of Zeeland. In England, 307 people were killed in the counties of Lincolnshire, Norfolk, Suffolk and Essex. 19 were killed in Scotland. 28 were killed in West Flanders, Belgium.
