This team addresses questions related to:
• the geomorphology of rivers and sedimentary bodies,
• upstream/downstream evolution of sediment transported on a “Source to Sink” continuum,
• coupling between reservoir geometry, water flows and sediment transport.
This team brings together about ten people with skills in hydraulics, seismics, geomorphology, hydrology, sedimentology, tectonics, 3D remote sensing and geophysics. One of the team’s main objectives is to foster cross-disciplinary exchanges. It presents the originality of extending the spatial scale of the problem from the catchment area to the grain characteristics (size, shape, size distribution), and of addressing the change in temporal scale since the morphogen event (flood) up to several million years (stratigraphic signal), in particular exploring the impact and signature of extreme events (earthquakes, storms). These are all research questions that range from fundamental aspects of understanding basic geomorphological processes to operational aspects of critical resource management and its impact on the environment.
