One of the major Thames floods happened in 1928. Prolonged heavy rainfall combined with high tides caused the river to burst its banks. The flood affected large parts of London, submerging streets, homes, and businesses. Several people lost their lives, and thousands were forced to evacuate.
To reduce the risk of future flooding, improvements and measures have been undertaken, including construction of embankments, raised river walls, and the Thames Barrier—a movable flood barrier completed in 1984. While these defenses have been largely successful in protecting London from flooding, the area still faces a potential flood risk during particularly extreme weather events.
