Aim of study
Describe morphology of tidal bars and channels Describe sedimentological variations Understand processes responsible for sedimentary signature
Facies descriptions and 3D geometry of sub-recent tidal deposits
Surface samples & sediment cores
Surface samples and cores
Depositional processes and cyclicity in Braganzavågen
Sediment description, X-ray and ITRAX of a long sediment core (6m)
High-resolution X-ray – depositional processes of laminae and cyclic patterns
Channel morphology from aerial photographs
Two types of drainage system interacting in the tidal flat: •
River channels meander, bringing sediments, evolving every year and moving laterally
•
Tidal creeks, accommodating the tide water, very stable over the 19years studied period
Mapping morphology of bars and channels and describing sediments
