A Quick Overview of Thames Barrier
The Thames Barrier is located downstream of central London. Operational since 1982, its purpose is to prevent the floodplain of all but the easternmost boroughs of Greater London from being flooded by exceptionally high tides and storm surges moving up from the North Sea.
