Abstract:
Sea-levels are rising in many areas around the world, posing risks for coastal communities and infrastructures. Strategies to manage these flood risks are often designed using decision analytical tools that integrate key geophysical, economic, and technological models. Previous studies analyzing sea-level rise adaptation strategies have broken important new ground, but are often silent on the effects of potentially important deep uncertainties and the trade-offs between diverse objectives. Here we implement and improve on a previously published model (van Dantzig, 1956) to represent multiple stakeholder objectives as well as deep uncertainties surrounding model structures and parameters. We analyze the robustness of different strategies in the face of the deep uncertainties and apply global sensitivity analyses to identify key decision-relevant uncertainties.
