Comment on LETTER: Removing sand from the Todd makes no sense as a flood mitigation measure by Charlie Carter.

Hal and Steve,
Note, my letter deliberately DID NOT mention the Casino causeway. I did not want to muddy the water. I wanted to concentrate on the sand removal issue. The point about the bed-level causeways is that they reflect the “natural” level of the river bed. The Casino causeway is more complex. In smaller flows (up to a 1 in 20) it reduces the river “cross-section” and therefore increases the water velocity. You do not see a sand build-up below a constriction. What happens above is complex, and beyond my expertise.
I was trying to avoid putting my relatively inexpert opinions forward, and am suggesting that we listen to the experts. I have had the benefit of sitting through the meetings and briefings that were part of the process of compiling the Flood Plain Management Plan. However, it’s 16 years ago, and like the people who see sand build up in the river, my memory is not perfect. That is why I went back to the document before I wrote. I suggest others do the same. Greg Buxton from ASTC responded to my comments on ABC Radio on Thursday.
When asked for the science to support the decision to remove sand he blustered and waffled and finished up with “observations” Peter Latz has often observed that scientific conclusions are sometimes “counter-intuitive”.
I would prefer to rely on the science in the ASFPMP than Mr. Buxton’s observations. He also misunderstood, or misrepresented, the FPMP. It does not recommend sand removal. Nor does it recommend “building bridges”. It does canvas these options, and dismisses both.

What kind of world is this?
Yes, I can see the similarities now that I look, and perhaps the fictional dream is combining the two somewhat.
Being originally from NSW I always thought of Sturt as being based there, which he was originally, only basing his third expedition from Adelaide.
And he did suffer from scurvy on his final trip.


What kind of world is this?
“From this first story we move to ‘At Failure Creek’, to the perspective of a “land explorer”, recognisable as Captain Charles Sturt: a man in a “weakened and near blind state”, perhaps close to death himself …

… to the dream of the dying man – of a glorious imagined parade down Rundle Mall”

This is blatantly, obviously, StuArt, not Sturt.

The ex-Pom who nearly missed the boat
Alex, from my very limited understanding of constitutional law, any legislation that attempted to vary the meaning or application of the Constitution would be unconstitutional.
It is my understanding that the only way out is a referendum to change the Constitution.


Gas deal: They can’t blame Giles for this one!
I’m not sure what the problem is here?
Given the present gas supply and price issues, locking in a supply at (presumably) 2009 price would seem to be a smart idea.
Again, given the present “crisis” in supply and price, selling off the surplus at a handsome profit should be child’s play.
