Morphodynamic development and sediment budget of the Dutch Wadden Sea over the last century

Nearly a century of bathymetric data reveals that the Dutch Wadden Sea, despite extensive human intervention, demonstrates remarkable resilience to rising sea levels and anthropogenic constraints. The study found that large-scale sedimentation—nearly 600 million cubic meters—in tidal basins has occurred, driven primarily by ebb-tidal deltas rather than gradual channel adjustments. While human measures like the closure of the Zuiderzee have significantly altered natural roll-over mechanisms (such as barrier retreat), the Wadden Sea continues to import sediment volumes exceeding those needed to counteract current sea-level rise rates. However, achieving a new equilibrium morphology may require sediment supplies beyond what remaining ebb-tidal deltas can provide. The research leverages long-term measurements to assess morphodynamic evolution and sediment budgets, highlighting both the system's adaptability and vulnerabilities under human influence.
