Those Australian floods are mega scary nothing compared to UK, they have open flat areas with no terrain resistance. Hard baked soil flats with no trees or foilage to support the course of water.The surface speed was immense , no saying what the undercurrents are like.
There are few traditional built properties there, they are mainly all large prefabricated buildings with no wall protection, water was crashing against the external walls at 180 degrees, the properties solums will be knackered. Where do you go due to the expanse of water, there is no chance of a pre plan emergency flood contingency plan working, nothing could cater or deal with such events.Everything is a hail mary just now.
Fire is horrific and deadly, but these type of floods are your worse nightmare. Congested buildings and towns cause water resistance in this country, their towns are so open.
God bless those poor souls, I,ve had a wee taste of dealing with flooding but nothing compared to this, this is a nightmare.
