Storm surge barriers, such as the Maeslantkering and Oosterscheldekering, are vital components of the Netherlands’ flood defense system. These impressive structures protect the low-lying delta from sea-level rise and storm surges. However, as these barriers age and sea levels rise, maintaining their effectiveness has become a pressing concern. A newly funded five-year project by the NWO aims to determine the best strategies to sustain a safe and liveable delta in the face of these challenges.
Linking Barriers and the Delta
The SSB-Δ (Storm Surge Barrier Delta) project brings together universities, knowledge institutes, water boards, and companies to explore the interplay between storm surge barriers and the surrounding delta. Led by TU Delft’s Bram van Prooijen, the project seeks to integrate technical expertise with societal perspectives to ensure well-informed decisions. This collaborative effort will address immediate maintenance needs and assess long-term strategies, including adaptation or replacement of the structures.
Planning for the Long-Term
Much like deciding whether to repair or replace a car engine, the project will weigh the costs and benefits of maintaining existing barriers versus exploring alternatives. With structures like the Maeslantkering expected to remain operational for 50 more years, planning must start now to ensure future experts, including today’s PhD students, are equipped to handle the challenges ahead. The goal is to provide clear, actionable guidelines that balance technical, environmental, and societal needs.
