Would this work and if not why not
Discussion
A couple of days ago I answered 'deeps' thread about sea levels with what follows, It now really has me wondering would it work and if not why not? Your opinions please.
In the middle of Australia was a massive inland sea called Lake Ayre. It's now as dry as a dry thing.
If a pipe line was run from say the Gulf of Carpenteria to Lake Ayre which is obviously below sea level and we filled it up, shirley the level of the sea would drop.
And as an added benefit Oz would have an inland sea again which would encourage wild life which would bring vegetation and rain to the inland and everyone wins and all the doom and gloom greenies can F off.

Seems quite sensible to me.
I think either the whole pipe would have to be below sea level or you'd need Mick Jagger to start siphoning.
It would also have to be very big diameter pipe, in fact it would probably be easier to dig a canal.
Why did Lake Ayre dry up and what stops it happening again? also, what affect would all that seawater have on Australia's water table?

Yeah, it would have to be a big pipe and long, but they run gas from Russia. I don't thik it being full would 'cause too much of a problem as it gets water in it every ten years or so. which is amazing to see. As fish come out of nowhere and birds and animals come for miles. then it all goes again. Don't know why.
you would think if it was kept full it would open up a whole new habitat. (not like the one in Brent Cross)

How far below sea level does Lake Ayre go? Because I can't imagine its going to make a great deal of difference personally.
Like using a paddling pool to deal with a flood. I may be wrong though, depends on how big it is.
It's bloody massive, just about turn Oz into a donut.Like using a paddling pool to deal with a flood. I may be wrong though, depends on how big it is.

How deep is it though? If its 20 feet deep over 1000 square miles, thats not going to make alot of difference.
Does anyone live in it?
Are there major roads/railways that run across it?
I'm not sure of the exact area it covers. No-one lives on it and nothing is built on it. It's salt flats when it hasn't water in it. Does anyone live in it?

Might stuff a few land speed records if it was kept full but that's about all i can think of.
And 9,500 square klms in area. that would take a drop or two to fill

Cool. Can't find any reference to the surface area, but I doubt it'd make much difference.Robg said:
Keeping Lake Eyre full will increase water vapour in the atmosphere above the lake, possibly leading to more summer storms in eastern Australia, and perhaps a little more rain over the eastern ranges during winter, when cold fronts meet the easterly progressing “moist” air from Lake Eyre. However it would be better to analyse rainfall observations from when Lake Eyre did fill in 1949 and determine whether the filled lake generated any material change rainfall patterns in the local area and eastern Australia. The challenge with this task is that rain in Australia is so variable and subject to the El-Nino Southern Oscillation phenomenon that it would be difficult to discern any difference.
Based on the 1949 experience and the fact that the Lake has since dried out, I think the cost of keeping it full would be enormous in terms of infrastructure and energy. Though in theory you could siphon sea water into the lake, the daily volumes are truly staggering just to counter the 2000mm annual evaporation. The lake covers 1.14 million square km and has an average rain of 250mm. Assuming a net evaporation of 1.75m per year, you would need to pump in excess of 5,400 GigaLitres of water per day just to maintain the water level (that’s equivalent to 10 Sydney Harbour’s worth of water per day!). As to turning our desert into productive land – Australia is geologically one of the oldest continents, so our soils are exceedingly infertile and saline. As a keen gardener, I have learnt that poor soils are a costly waste of time and money. The words “pipedream” come to mind.
