Staring at a map of Australia, you can see that we've got a system of
rivers- there should be someway we can tap into them - creating canals,
reservoirs and aquaduct systems (underground) to pipe water from areas
which flood to areas which are dry.

What's the cost? One billion dollars? Ten billions dollars? Probably more.
Will it be done in ten years time, twenty? forty years perhaps? I think
its feasibily - anything is better than seeing parts of our nation flood,
farming communities dry out, and just swatting the flies off our faces.

If you are looking at a topographical map, you will notice that Australia is
virtually flat and that means that most rivers are shallow and that the
rivers that have water in quantity, have it for only a relatively short
period of time and event hen it spreads out on the floodplain.

Canals have worked over relatively short distances in other countries with a
much higher population density but in our conditions they would suffer
evaporation badly.

Exactly

Reservoirs work best where there are steep ravines
through which a river passes and this has largely already been done where it
can be. In order for pipelines to be effective you would need permanent
access to large quantities of water to make building them effective and
where woudl that be?


Not to mention that every time you build a dam you cover many kilometres of
land, often very productive land as it is in in river valleys.

Dorathea Mackellar was right. "Droughts and flooding rains" That has
always been our pattern and that is also why Aus has the topographical
profile it does now. We live in a truly ancient continent and I strongly
suspect that peak oil and the lack of progress on solar energy means we will
not be faced with any solutions in the short term (by which I mean anything
up to 50 years from now).



A more realistic view.

David I don't know if you are old enough to remember the old 'Nation
Review'. If you aren't old enough, it was a newspaper full of well written
meaty articles but with a tendency to the leftist side of the political
spectrum. I don't care about that: I just want information and thoughtful
comments so I can make up my own mind.

Given the dearth of decent commentary of any sort over the past decade or
so, I have long wished for such a publication and I think I have finally
found something very similar.

I wrote my comment on water and topography yesterday and today picked up a
publication that I've only read only once before but I'm going to do so
regularly in future. The publication is called "Dissent" and it has some
interesting articles on the environment (and one article on the escalation
of debt in Aus with a very disturbing chart showing debt to GDP from 1880 to
now - I haven't read it yet but am itching to do so). Anyway, I suspect you
might have a simialr interest in some of the things I do so just want to
mention it in case you are interested. Cost $7.70 - seems to be a
quarterly.

I am. I do.

I will keep my eyes open

Don't know it at all!

Linda (not the one wantng to do the lawn, the one with the Zucchinis.
Any ideas for Cherry Tomatoes???)
Er grow them, give them enough water, dont plant them under trees where
there is shade, and kids, and allow them to ripen.
Then eat them? Sounds good to me!!!!

Oh Chardonnay goes well with them, as does a salad, onions and good company!
