physical causes
The winter of 2013-2014 was the wettest on record for the UK, with 486.8 mm of rain from December to February, surpassing previous records.
A series of Atlantic storms brought heavy rain and strong winds, saturating the ground and causing high river flows.
By February, groundwater levels were extremely high, and rivers in the Thames region were close to bursting.
human causes
The Jubilee River, a man-made flood channel, was designed to prevent flooding around Maidenhead, Windsor, and Eton by diverting water from the Thames.
However, this channel sent water faster to downstream areas like Wraysbury and Staines, where the Thames couldn’t handle the additional volume, worsening the floods.
