Coastal flooding estimation at large scale, e.g. pan-European is usually performed using static method while dynamic method, in which numerical flood models are used to solve hydrodynamic equations, have proven perform better. However, a model can rapidly become computationally demanding. Thus, respect the balance between efficiency and quality, need be properly configured. Usually, configuration supported by calibration validation. In cases where it not possible appropriately implement...
