Guess that those benefits make nice homes... 
Such flooding is always a tragedy and it will probably not be very long before the press starts blaming the government for not doing the proper maintenance in time.
Yep, the government's fault that some half-wit decided to build next to a possible overflowing water source and/or on a flood plain.
Honestly, there are reasons why the land and housing is cheap in flood prone areas....oh, and reasons that the people living in those areas can't get insurance due to companies refusing to insure accident prone areas.
As dickish as it sounds, flooding will happen. Deal with it. If you don't want to deal with it - move somewhere that isn't on bloody flood plains or right on the banks of rivers that do not have proper flood defences. There are places in this world that take the brunt of much more serious flooding.
I'm not going to sit and say "AMAGAD I HAZ NO SIMPATHEH FUR DEM" as people can lose everything up to their own life in these sorts of situations. But the same places are affected every 6 months to every year, you would think someone would have the sense to just move away. Boycotting the system seems like a much better idea than saying the government aren't doing their bit to help with flood defences, because in short there are no "flood defences" that can really help in an area where the river has been redirected by concrete and asphalt.
