Abstract: This study presents a robust framework for analysing compound flooding events in estuarine regions, where the interaction between freshwater and coastal waters creates a complex scenario for flood hazards. Traditional risk assessments tend to overlook the interconnected nature of flood drivers, potentially yielding inaccurate risk evaluations. Here, our methodology comprises a two-step process that seamlessly integrates statistical and hydrodynamic models to estimate the joint probability of compound events and their associated hazards. To ground our findings, we focus on the Santona estuarine ecosystem in Northern Spain, offering a practical demonstration of our approach, and leveraging the interactions between six distinct flooding drivers. Through this case study, we shed light on the nuanced dynamics of compound flooding, illustrating how these insights could inform more accurate risk assessments and enhance flood management strategies. Our findings indicate that the multivariate approach outperforms the traditional univariate assessment method in terms of comprehensiveness, generating results more compatible with observations.
