Methodology for the characterization of marine-driven erosion and flooding processes and the assessment of their impact on the Catalan coast

Methodological report defining how to characterize flooding and erosion along the Catalan coast, considering present conditions and climate-change scenarios (SSP2-4.5 and SSP5-8.5). It proposes combining wave and sea-level data (IH Cantabria, CNRM), calculating flood elevation (MM+MA+run-up+SLR), and using the XBeach model (1D/2D) to delineate hazard, alongside an approach to estimate erosion and assess risk in GIS.

Purpose: To establish a methodology applicable to the entire Catalan coastline to define flood elevation, model flooding and erosion, and produce hazard and risk maps integrating vulnerability and exposure.
