Hydro-sedimentary dynamics (DHYSED)
The DHYSED laboratory focuses on the hydro-morpho-sedimentary functioning of the coastal zone, from estuaries to plateaus (muddy and sandy-muddy environments), associated processes and interactions with other ecosystem components.
This issue is addressed through a multi-scale temporal approach, from tidal to multi-decadal scales, including the impact of extreme/intensive events (floods, low water, storms) and the effects of global change. The aim is to anticipate changes in the trajectory of the coastal environment, through 3 main themes : 1 ) the land/sea continuum and the hydro-morpho-sedimentary evolution of estuarine zones, 2 ) the study of coastal habitats and interactions between biotopes and biocenoses and 3 ) the study of sedimentary flows on the scale of continental shelves
To address these issues, the laboratory relies on a strategy combining laboratory experimentation, in situ observation and modeling, via the development of the MUSTANG model coupled with various hydrodynamic models (MARS3D, CROCO, SYMPHONIE).
