The Oosterschelde Storm Surge Barrier is a large flood defense structure located in the Netherlands. Completed in 1986, it protects the surrounding areas from storm surges and rising sea levels by controlling the flow of water in the Oosterschelde Estuary. The barrier consists of a series of large gates that can be closed during severe weather events to prevent flooding. This engineering marvel is part of the larger Delta Works project, which was initiated after the devastating North Sea Flood of 1953. The Oosterschelde Storm Surge Barrier is notable for its innovative design, allowing for both flood protection and the maintenance of the estuary's natural ecosystem.
