| This work has been performed in a DRET/CNRS convention and related to the problems of sedimentary dynamics in a bay dominated by tidal currents. It combines the descriptive study of the morphosedimentary units with the modeling of bedload processes. At the South channel Isles, the Mont-Saint-Michel bay is well known for his exceptional tidal range. It's open to the offshore with two broad master channels on both sides from the Chausey's archipelago. On the coarse sedimentary cover of pebbles and gravels, sediments dynamic series of some plurikilometres sandy ribbons. These sands are temporarily stocked in lonely bedforms and in coastal maritime banks, sandwaves field of Granville and tide delta. The coastal banks are connected in the littoral prism. They... |
