70 years ago today the great flood took place and flooded large parts of the southwestern provinces of the Netherlands. After that, the Delta works were built to protect the South West Delta. While the area is still well protected from flooding, it is unsure how long these measures will be sufficient in the light of sea level rise.

As part of the national knowledge program on sea level rise (Kennisprogramma Zeespiegelstijging) we explore different long-term development directions and their spatial and functional implications to ensure a resilient delta area in the future.
