Utilitzant el model SFINCS, un model digital d’elevacions d’alta resolució i dades d’entrada de marees ciclòniques i onatge, es simulen les dinàmiques d’inundació en condicions extremes. L’estudi se centra en la regió de Ligúria i avalua el rendiment del sistema amb finalitats d’alerta primerenca. Els resultats mostren l’eficiència del model i el seu potencial per ser integrat en fluxos de treball de protecció civil en temps real. Esta tesis presenta el desarrollo y la aplicación de un sistema operativo de previsión de inundaciones costeras para el mar Tirreno septentrional. Utilizando el modelo SFINCS, un modelo digital de elevaciones de alta resolución y entradas de marejada ciclónica y oleaje, se simulan las dinámicas de inundación bajo condiciones extremas. El estudio se centra en la región de Liguria y evalúa el rendimiento del sistema con fines de alerta temprana. Los resultados muestran la eficiencia del modelo y su potencial integración en flujos de trabajo de protección civil en tiempo real. This thesis presents the development of a reproducible coastal flood modelling framework for the region of Liguria in Italy, using the open-source model SFINCS (Super-Fast INundation of CoastS) made by Deltares. The main goal of the thesis is to create a flexible and welldocumented setup that can both be used and expanded by future students and researchers, rather than to perform very detailed flood forecasting. The model was tested with the October 2018 coastal storm as a reference event. Digital elevation data (topography) from the Liguria Region Geoportale was combined with bathymetry data from GEBCO to build a high-quality complete elevation model of Liguria and is ocean. The final simulation was run on a 50×50-meter grid, using combined tide and storm surge with wave run-up boundary conditions over a five-day period. Output files from the SFINCS model were used to analyze water levels at the boundary points and flood development at selected coastal locations over time. Despite not being calibrated against real world measured flood data, the model showed realistic behaviour. Flooding occurred in the low-lying areas of Liguria such as beaches and harbours, while areas with steeper terrain and cliff faces remained dry. The results demonstrate that SFINCS can simulate the main tendences of coastal flooding in Liguria and that the framework is suitable for future testing, teaching, and continued development. 2025-09-19T20:26:34Z 2025-09-19T20:26:34Z 2025-07-23 Master thesis http://hdl.handle.net/2117/440532 http://creativecommons.org/licenses/by/4.0/ Open Access Attribution 4.0 International Universitat Politècnica de Catalunya
