Modelling Belgian Coast. ScaldisCoast. Sub report 2. Updates ScaldisCoast 2025
This report documents the latest release of the ScaldisCoast numerical model, developed to simulate both long- and short-term morphological evolution along the Belgian coast under varying hydrodynamic and meteorological conditions. Key developments include the transition from the SISYPHE to the GAIA sediment transport module and the upgrade of the TELEMAC modelling system to version v8p4. In addition to ensuring consistency across modules and versions, particular attention was given to the adoption of the Flather formulation as the default wind drag formulation in the new version of TELEMAC system, which significantly improved hydrodynamic accuracy during the Ciara Storm event. The wave model TOMAWAC was also updated with an optimized numerical scheme, resulting in a 35% reduction in computation time and improved numerical stability.
Comprehensive validation of the morphological model was carried out using historical data and recent measurements from representative locations, including Zeebrugge, Wenduine, and Blankenberge. The model demonstrated satisfactory agreement with both long-term morphological trends and short-term storminduced sediment dynamics.
These results confirm the ScaldisCoast model as a robust and efficient tool for operational and strategic applications, supporting coastal defense planning, sediment management, and climate adaptation along the Belgian coast.
