What 3 inches of flowing water (& mud) does, is literally evil. So I can't imagine what it is like for the people of Lismore, Gympie and other places that got metres/yards of water go through their homes. Even with the little that we copped, I am needing to spay the toxic crap against mould, all I see with the homes that were literally under water all the way above their roof is "demolition" and rebuild.
At least I was able to take notes where and how to prevent it from happening in future, to detour any crazy amount of rainfall, but how does one prevent meters of water and mud and shit that just keeps rising!
Can you build like a retaining wall and some kind of culvert to reroute it should it happen again?
I'm gonna dig trenches, tank trenches like the ones in the former yugoslapheadia, where anything unwanted tries to cross gets stuck and goes down, from wild pigs to tanks and flowing water.
I will figure something out, just need the time, patience, money and willpower!
