Description :
This paper examines the stability of river channels and their associated valley floors in the uplands of Scotland since 1750. Changes in global-scale atmospheric circulation patterns during this period have resulted in regionally district flood-rich and flood-poor periods with potential geomorphic impacts. Changes in the planform of 9 active rivers in the piedmont zone of upland Scotland are examined from series of rectified maps and aerial photographs at scales close to 1:10 000. Differences in geomorphic history, land use and degree of slope-channel coupling are identify as the likely causes of marked differences in the behaviour of active rivers in Scotland and northern England over the last 250 years.
