Thames Barrier closes for annual test ahead of 200th operational closure

The video discusses the threat of tidal flooding in central London and the role of the Thames Barrier in mitigating this risk. The barrier, located at Charlton, spans 520 meters across the river and prevents incoming tides from moving upriver. Historically, London has faced flooding threats, but the Thames Barrier and associated defenses have significantly reduced this risk. The barrier has been closed 199 times for flood defense, with a total of 613 closures including tests.
