Coastal regions are increasingly vulnerable (e.g., erosion/flooding) to combined stressors such as sea-level-rise, extreme weather events and anthropogenic pressures. Coastal risks top out in stretches where infrastructures and ecosystems interact, leading to growing hazards and vulnerabilities that require a robust assessment of trade-offs and synergies, particularly under climate variability. The current wealth of high-resolution simulations and observations for coastal domains offers a unique opportunity to reduce risks in these dynamic environments.  This session invites contributions tackling numerical coupled models, observational systems (in-situ and remote sensing) and hybrid approaches that integrate observational data with predictive models. The session focuses on the application of these models and observations to harbour-beach interactions, where the prediction and real-time monitoring of hydro-morpho-structural interactions are an urgent requirement to curb growing risks. Papers dealing with model validation, data assimilation and uncertainty quantification for restricted coastal domains are welcome. Submissions addressing single or multiple forcing mechanisms — such as tides, waves, storm surges, river liquid and solid discharges —are encouraged, as are those that consider forecasting challenges for complex, data-sparse, or rapidly changing environments. This session aims to foster interdisciplinary exchanges and highlight innovations that support the next generation of coastal models.
