EVOLUTION OF HYDRO-SEDIMENTARY SERVICES OF COASTAL STRUCTURES IN THE CONTEXT OF CLIMATE CHANGE – PALAVAS-LES-FLOTS (34)
Duration: 4 months (May–August 2025)
In the context of climate change, the medium-term effectiveness of so-called "grey" coastal structures, such as breakwaters and groynes, remains poorly assessed .
Commissioned by the Agglomération Pays de l’Or and the Entente du Golfe d’Aigues-Mortes, LINEUP OCEAN conducted a 4-month study aimed at determining the effectiveness thresholds of a set of breakwaters and groynes in the region, taking into account hydro-sedimentary changes driven by climate change.
To meet this objective, a multi-scale hydro-sedimentary numerical modelling strategy was developed , incorporating different weather-ocean forcing scenarios and multiple time horizons. This approach was based on a recent and updated dataset, obtained through topographic and bathymetric survey campaigns (remotely piloted drones / next-generation sensors), which allowed for precise calibration and validation of the numerical models.
This work provides concrete insights into the durability of existing coastal structures and serves as a valuable resource to inform decision-making and guide the development of next-generation protection solutions, integrated into broader coastal adaptation strategies .
