摘要

The coastal areas are the theatre of increasing erosion and submersion risks by gathering growing hazards and exposures. Nature-based resilience is here mapped at 2 m spatial resolution using a novel fusion of morpho-bathymetry classification, derived from airborne bathymetric LiDAR, and graph-based network modelling. Connectivity results were discussed in light of coastal management.
