This research is focused on testing the sensitivity of this model to its input parameters by verifying the effects on key output indicators for coastal managers, such as wave run-up, beach erosion, shoreline retreat and inundation. The model is applied to Cesenatico and calibrated based on the data measured during an extreme storm event, with the mid-term purpose of calibrating the model for the Emilia-Romagna coast, which suffers from subsidence, erosion and flooding.
