Brisbane facing floods

I visited Brisbane in the rainy season last year, but this year has had much more rain. What's amazing is that Brisbane experienced exceptional drought just a few years ago, leading people to cut water use AND build a desalination plant that's now mothballed.

The floods will be worse to the extent that the river going through the city does not have room to flood, because buildings are in the way.

Bottom Line: Build huge dams to buffer floods and droughts, or just give nature room for both and keep demand to levels consistent with drought.
