These two geophysical campaigns aim to improve the knowledge and understanding of sedimentary morphodynamics at the SEM-REV sea test site and around its infrastructures. These campaigns will complete and refine the datasets necessary for:

1. To control the depth of burial of the electric cable against the morphodynamic processes;
2. To control the risks associated with scouring phenomena around submerged structures;
3. Improve the reliability of materials in the face of abrasion problems;
4. To validate a regional sedimentary morphodynamic model under development at the LIENSs laboratory to assess its ability to account for mid-depth bathymetric evolutions;
5. Contribution to the data acquisition for the WEAMEC Hoopla project which aims to study the settlement in Haploops off the Croisic.
