Description :
The AA. report on the development of a multi-proxy flood history for the River Tay, Scotland, drawing on the sediment archive of a major palaeochannel complemented by archival, historical and epigraphic flood records from the city of Perth. This paper demonstrates that proxy flood records extending over 200 years can be successfully recovered from sediment stacks in palaeochannels adjacent to major rivers. The hypothesis that each local coarsening in the stack represents a flood signature which can be individually dated by Pb 210 or Cs 137 is also confirmed.
