Barrier Gates for London's Thames' Doorstep

Thames Barrier Park, the barrier, and an apocalyptic London globally warmed?

In the far eastern corner of London, next to the Docklands development, is one of the more unique parks in the city. Sleek pavilions, manicured hedge rows, and wide grassy areas lead to the edge of the Thames and the behemoth that keeps the river in check. Rising like 10 silver-backed armadillos, the  Thames Barrier is marvel of modern engineering. London is susceptible to flooding since the Thames is very tidal and North Sea winter storms regularly roll up a long and broad estuary. The barrier's curved gates normally lie on the river floor, but if needed, huge rocker arms rotate up to provide a five-story wall. Built in 1984, the barrier is 1.5 meters higher than the last great flood in 1953 but is typically raised at least twice a year. A barrier now, but who knows what the future holds if the seas continue to rise as a result of climate change?
