Short summary
This study evaluates the performance of an EWS (Early Warning System) for coastal flooding operating at a beach scale. The system captures total water level exceedances based on predefined morphological thresholds and trigger timely warnings, particularly under energetic conditions. Its forecasts are found to align well with selected overtopping events of varying magnitude and duration, leading to flooding of the berm-dune zone, which have been monitored by on-site coastal videocameras.
