Of course it will happen again rache, just as it has in the past, in fact over 120years ago.

What do you think caused those floods, it certainly couldn't have been CO2.

To build tidal walls across the Brisbane River similar to London's, the cost would be around $6 billion. Another proposal is for the council to buy flood effected properties.

Hassy, do you still rely on that Old Fart up the road to give you all your weather info. You will go to your grave a climate skeptic.

rache said- "Arguing over symptoms rather than addressing causes is an interesting mental exercise but really just a waste of time and the chances are it will all happen again in another few years."

Answer- What is Rache doing to address/ understand the causes? Perhaps Rache could study hydraulic engineering for a couple of years if she disagrees with the experts and prove them wrong. Perhaps the answer is to move Brisbane- not a happy feel good solution.

The "cause" is too much water being dropped from the sky in too short a time- this is obvious- this is why engineers talk about symptoms. Maybe we could move the sky to a different location- maybe we can move the clouds- or the land to a different location- maybe we can change the slope of the land. If the sky is dropping water on a surface faster than the surface can drain the water away then the level of the water on the surface will rise and cause damage to the structures on said surface.

Maybe you could do a grid point analysis and modelling of Queensland and vary the water dropped per unit area per unit time on said surface and see if the water rises. Then see if the neighbouring areas/ paths have similar dissipation rates to determine the possibility of redirection/ remediation measures.

Maybe we could knock down all the fences on the property lines in Brisbane to facilitate better hydraulic flow across the land.

Maybe we could catch lightening bolts from the sky and store them in batteries.

The power of nature is often impressive- though at times rare and brilliant engineers have been able to change it.

Maybe off-hand comments can be just as useless and destructive as symptom analysis

the cost would be around $6 billion.
Paul1405,
That's peanuts over 25 or so years ! That's the change we get from the hordes of Public servants in questionable positions with no evidence of positive contribution !
Forget locks, widen/deepen the water courses.

Hi Indy,

There are many larger cities with rivers flowing through them. There are several that have flood relief systems in place. So there are practical ideas our there that Australian governments can investigate.

Lismore has a levee system.

Levees have a history around the world of failure. Perhaps if we got the Dutch to design & build them, they just might work.

Paul Anyone not a climate skeptic is a bloody idiot.

Yes I'll go to my grave a climate skeptic, along with my official bureau figures you chose to deny.

Better that than live & die a useful idiot.
