1947 Thames flood
The 1947 Thames flood was worst overall 20th century flood of the River Thames, affecting much of the Thames Valley as well as elsewhere in England during the middle of March 1947 after a severe winter.
The floods were caused by 117 mm (4.6 inches) of precipitation (including snow); the peak flow was 61.7 billion litres of water per day and the damage cost a total of £12 million to repair . War damage to some of the locks made matters worse.
Other significant Thames floods since 1947 have occurred in 1968, 1993, 1998, 2000, 2003, 2006 and 2014.
