The Netherlands utilizes advanced water management and large-scale engineering to protect its territory, much of which lies below sea level. Following a devastating North Sea storm in 1953, the nation transitioned from traditional dike repairs to visionary projects like the Delta Works. This system includes the Maeslantkering storm surge barrier, which uses automated steel gates to protect the Port of Rotterdam.

Recent efforts have focused on modernizing existing infrastructure to combat climate change and rising sea levels. A significant milestone was reached with the completion of a major reinforcement phase of the Afsluitdijk, a 32-kilometer hydraulic barrier separating the Wadden Sea from Lake IJsselmeer. While this specific reinforcement phase is finalized, the Dutch agency Rijkswaterstaat continues to oversee broader modernization works for the Afsluitdijk system, which are expected to proceed through 2030.
