How Does the MOSE Flood Barrier Function During High Tides?
The MOSE Flood Barrier functions during high tides by using a system of barriers and gates. When high tides approach, the system activates. The barriers rise from the seabed to block tidal waters from entering the Venetian Lagoon. The gates inflate with air and seal off the water, preventing flooding in Venice.
The main components include large barriers, a control system, and pumps. The control system monitors tidal levels and weather conditions. When forecast data indicates an incoming high tide, the system triggers the barriers.
The pumps then fill the barriers with air. This rising action creates a physical barrier against the incoming water. As the tide recedes, the barriers lower back into the water, allowing normal water flow to resume.
This process occurs quickly, often within a few hours. The design ensures minimal disruption to marine traffic. The system is essential for protecting Venice against rising sea levels and frequent flooding. The MOSE Flood Barrier is a significant engineering solution, aiming to safeguard the city’s unique environment and heritage.
