BGS flood response

Geological maps show where all the floodplains and coastal plains in Britain are located and therefore the main areas at greatest risk of flooding. From this information BGS has produced a map dataset called ‘geological indicators of flooding’ (GIF). To investigate the link between floodplain extent and extreme flooding events, BGS carries out aerial surveys after a flood event disaster. This photographic collection will be used to improve our understanding of floodplain processes and management of floodplains. By extracting and digitising the actual extent of the flooding, these images also provide first hand information to validate the GIF dataset.
