Description :
The AA. compare and evaluate all lichen-dated flood deposits from UK upland river basins in order to assess changing flood risk over the last 250 years. The analysis indicates that the incidence and size of exterme events have markedly decreased over the last 50 years, and may be at their lowest level since AD 1750. Occurrence of extreme upland floods over the last 200-300 years appears to be associated with negative North Atlantic Oscillation index values and significant non-stationarity evident in the historical floods series is shown to relate to decadal and multi-decadal scale climatic fluctuations.
