Abstract
This paper assesses the spatial variations in types and rates of channel migration over an historical time-period on the middle River Coe, Western Grampians, Scotland. The study reach represents an exceptional example of an integrated channel system, which displays progressive downstream adjustment in both hydraulic geometry and planform characteristics from a mountain torrent environment, through a wandering gravel-bed river section to a low-angle, gravel delta within a fluvio-lacustrine environment above Loch Achtriochtan. Spatial and temporal variations in channel planform adjustment and floodplain reworking are related to variations in bankfull discharge, associated stream power and channel competence.
