The rain along the east coast is not unusual, but the runoff is.
Because rain is part of climate , ignorant climate activists open their big mouths and misdirect resources concern and cynicism .
In investigating the huge damage to houses in the Barwon river floodplain in November 1995 , I was surprised to learn that neither the Engineers Australia guidelines for runoff estimates or the Met Bureau records were of any use in really understanding the ongoing very high risk of bigger than expected floods from some mountain areas , especially when moist easterlies were operating .
To put it simply, the modelling is not dynamic enough to pick upon the many site specific factors ( like orography ,soil erosion and bedload ) that cause these unusually large amounts of water and silt rising out of channels . .
The failure of planning authorities to anticipate a very high level of
risk is evident in the sloppy way these floods are reported and NOT anticipated
when moist easterlies are active . (ongoing exposure near the Brisbane river
locals as a result of constant rain near Toowoomba.

The best way to picture the risk is to remember the limited ability of most
clouds to produce more than an inch or two of water and the cooling
effect required to get even that amount . What happens in these
rare but quite predictable occasions is that the rising hills provide the
orographic cooling effect required to et a train of clouds to give
up their moisture on one locality for many hours on end.
2 inch per hour in one spot becomes 20 inches in one spot and no soil can take it as we can see ( if we have eyes to see ) in the water .We can even see a bit about "whose soil where" by the color
.
If we allow ignorant wannabes to continue to blame everything on climate
change, there will be deaths and destruction because of them because they
redirect support away from the real consequences of real environmental
risks we should be facing .
