Thames Barrier

The Thames Barrier is a large flood defense structure on the River Thames in London, designed to protect the city from flooding caused by high tides and storm surges in the North Sea. It consists of 10 movable steel gates that can be raised to block incoming water during high-risk periods, allowing the river to flow freely at other times. By controlling water levels, the barrier helps prevent flooding in London’s densely populated and vital areas, especially during severe weather events. It’s one of the world’s largest movable flood barriers and a crucial part of the city’s flood management system.
