International audience. This study applies the reduced-complexity model LX-ST to simulate the future evolution of the shoreline and nearshore morphology of Lacanau, a wave-dominated, erosion-prone coastal site in southwest France. By coupling longshore transport with shoreface translation processes, the model evaluates changes under various IPCC sea-level rise scenarios through 2100. Results highlight significant spatial variability in erosion, with pronounced downdrift retreat near coastal defenses. The findings demonstrate the utility of LX-ST for informing long-term coastal adaptation strategies.
