Description :
This paper summarizes existing research results on the hydrogeomorphology of the 18 km reach of the lower River Dee. It describes the preparation and analysis of channel cross-sectional surveys from 122 locations along the reach, and then assesses the process significance of the observed morphological trends. The possible relationship between channel form and process within the study reach is explored by identifying 4 stretches of river that are differently influenced by tides and the tidal weir. The extent to which recent flow regulation has affected channel form in each of these 4 stretches is also considered.
