Barscale morphodynamics through the tidal-fluvial transition (2016)
Thesis
Keevil, C. E. Barscale morphodynamics through the tidal-fluvial transition. (Thesis). University of Hull. https://hull-repository.worktribe.com/output/4219287

A complex transitional zone within river-estuary systems exists between fully-fluvial and fully-tidal conditions. This zone varies both spatially and temporally across a range of scales. The resultant sedimentary transport and depositional characteri... Read More about Barscale morphodynamics through the tidal-fluvial transition.
