Quantification of Safety Standards for Small Islands in the Wadden Sea

Small islands in the Wadden Sea, particularly the Northfrisian Halligen, face significant storm surge risks due to their low-lying nature. A key finding from this study is the establishment of maximum allowed water depths on artificial dwelling mounds—critical structures that remain above water during extreme weather events—to prioritize protection measures. Using numerical simulations, researchers tested compliance with these safety standards by modeling wave overtopping effects, providing a data-driven approach to assess flood risks. This method offers a scientific basis for improving the resilience of these unique coastal communities, traditionally reliant on non-scientific design practices.
