Modelling wave overtopping along urban waterfronts during severe storms requires resolving tightly coupled wave, water-level and local impact processes.     Overtopping in severe storms is rarely driven by a single process and remains one of the most complex coastal flooding processes to model accurately.    In urban waterfront settings, wave run-up and overtopping can be highly localised, difficult to reproduce and critical to get right.    In a project in France, the challenge was to represent the full flood pathway reliably across the entire exposed waterfront, while matching observed behaviour from camera monitoring and historic storm events.    Using 𝗠𝗜𝗞𝗘 𝟯 𝗪𝗮𝘃𝗲 𝗙𝗠, new functionality was explored to better represent overtopping along defences and coupled wave-water level effects. The model was calibrated against camera monitoring and historic storms, showing good agreement with measured data.    The result was an improved fit to measurements, stronger calibration against historic events and clearer visualisation of storm consequences across the full exposed waterfront, including under future climate conditions.    This provided local authorities with stronger insight for flood assessment and early-warning planning.    When physical complexity demands more than a standard model setup, the right combination of tools and methodology makes the difference.    Learn more about 𝗠𝗜𝗞𝗘 𝟯 𝗪𝗮𝘃𝗲 𝗙𝗠: https://lnkd.in/gt5zGA8j    #WaveOvertopping #CoastalFlooding #CoastalEngineering #HydrodynamicModelling #MIKE3
