Deborama's WWW Number 33 - London Under - water?

My new m.o. for Wednesday Website of the Week is to start on Friday and work my backwards. So this one is only one day late, a 100% improvement on last week! This week's WWW is not a site exactly but a theme, a film coming out in a little over a week which is a fictional tale of London in a disastrous flood.
In 1984 the Thames estuary southeast of London inaugurated a system of flood defence in the form of the massive Thames Barrier. It is the second largest flood barrier in the world, exceeded in size only by one in the Netherlands called the Oosterscheldekering. The film concerns a tsunami surging up the estuary and breaching the barrier (a scenario that the experts say is extremely unlikely but hey if it makes a good movie . . . )
It is a little uncanny that as this film was being made, floods of a fairly disastrous type were hitting Britain in real life, even if there was no tsunami involved and London was barely affected. Meanwhile, monsoon floods have claimed hundreds of lives in south Asia. And if it's not water, it's fire: I just saw the most appalling footage on the TV news of a towering inferno sweeping through suburban Athens (Greece, not GA) propelled by gale force winds.
