Self-Deploying Flood Barriers


Initially developed and deployed in the Netherlands, self-raising flood barriers are a passive flood defense system that uses rising water to automatically raise the flood barrier. As the floodwaters recede the barrier automatically retracts. The beauty of this system lies in the fact that it is virtually invisible allowing residents and/or visitors unobstructed waterfront views when not in use and does not require human intervention or a regular power source for deployment.
