The document summarizes research into the possible causes of the 1607 flood in the Bristol Channel area of the UK. It describes evidence from historical documents of a catastrophic flooding event. The researchers investigated the theory that it was caused by a tsunami rather than a storm surge, through field work examining coastal landscapes and sediment layers for tsunami signatures. While the data collected added to the debate, the researchers were unable to conclusively determine whether a storm surge or tsunami caused the 1607 flood.
