Researchers have used field, archival and modelling sources to investigate the dynamics and long-term behaviour of meandering channels to help understand and predict future changes. There is still a great deal of uncertainty about why different meander bends are active and why similar bends are stable. Questions also remain about how the impact of change on one part of the river is propagated upstream and downstream. These questions are important as dynamic rivers can be challenging for human settlements, but also provide an opportunity to increase biodiversity and habitat opportunity in the riparian zone. The aims of this thesis are to explore the variability of meander migration in space and time for two actively meandering rivers in the UK. The long-term evolutionary behaviour of individual bends is explored using historic Ordnance Survey maps. Finally, a data mode...
