正文(英文) | The devastating flooding across the UK in February 2020 was remarkable in terms of the combination of duration, scale and severity, according to a preliminary analysis by the UK Centre for Ecology & Hydrology. Our briefing note provides an in-depth, initial hydrological summary of the record-breaking February floods. Highlighted findings include:
Persistent heavy rainfall resulting from Storm Ciara on February 8/9 triggered exceptionally high peak river flows, most notably across northern England in many of the same areas that suffered from flooding in November 2019 and winter 2015/2016. A week later, Storm Dennis generated similarly extreme high river flows, predominantly affecting Wales and central England.
The duration and severity of the high river flows resulted in extensive property flooding, most notably from the rivers Calder, Aire, Teme, Wye, Severn and Taff. However, the total number of properties affected across the UK was significantly lower than in previous notable flood events in winter 2015/16, summer 2012 and summer 2007. The Environment Agency says flood defences protected 128,000 homes across England in February 2020. He points out that it is challenging to collate information on the impacts of extreme events in a very short period of time, and says more comprehensive assessments will follow in the coming months. The Environment Agency, Natural Resources Wales, Scottish Environment Protection Agency and Northern Ireland Department for Infrastructure - Rivers have been continuing to manage the impacts of the flooding, and Dr Parry thanked these authorities for providing river flow data and feedback under difficult circumstances.
