Understanding the processes underlying coastal dynamics as well as the resilience of coastal and coastal systems is at the heart of the team’s scientific theme.
Understanding the changes of natural and anthropogenic origins requires a multi-method approach (in situ measurements, numerical modeling, physical modeling, biological indicators, remote sensing), multi disciplines (geomorphology, geophysics, hydrodynamics, sedimentology) and multi-temporal (since the instantaneous up to several thousand years).
The studied environments are mainly beaches, cliffs and sedimentary platform bodies including the upstream (watersheds, estuaries) and downstream (submarine canyons) areas when they participate in coastal and coastal dynamics. Direct or indirect measurements of the characteristic parameters of coastal dynamics (forcings, evolutionary geometries, environmental quality) are necessary both to complete and constrain numerical models, and to validate them.
We are therefore carrying out original instrumental and methodological developments, mainly in multi-sensor and multi-platform remote sensing coupled with in situ measurements to improve our 4D knowledge of the littoral physical environment. This multi-parameter and multi-scale approach to coastal dynamics is necessary to understand the phenomena of resilience.
A secondary objective of this team is to develop new tools, methods and indicators geared towards civil society and the socio-economic milieu. These indicators will concern coastal risks (biodiversity / water quality / shoreline evolution).
