The project aims to spatially extend the integrated OSIRISC coastal erosion and submersion risk observatory to new coastal territories in the Brittany Region. It will make it possible to innovate in this observation by developing the tools, transferable regionally at the end of the project, for monitoring the vulnerability of specific regional coastal issues that are inevitably affected by the consequences of ongoing and future climate and global changes: seaports, coastal roads, coastal trails, second homes, shellfish farming areas and foreshores.
