Comment on Sands in Todd more stable than you think (re-published with Maxine Cook’s comment) by Hal Duell.

I’m not arguing, just asking a couple questions.
In the first photo there is a not particularly visible sand island that is not covered with any anchoring vegetation. In the second photo there is a clearly visible sand island that has been covered with vegetation that would help keep it anchored in place.
Does a sand island seen in the same spot in photos taken so many years apart imply the possibility of a natural eddy at that spot in any flow of the Todd? And if so, could today’s floods coming upon an anchored island build up that island until it becomes an obstruction? This is assuming that any flow of a river, coming upon an obstruction and therefore being checked to some extent, will drop at least some of the sediment it is carrying.
I think it is worth remembering that not all floods are raging events. Some are quite lazy, but they all carry sediment that can be left behind to be anchored with grasses.
Is couch with its root system more effective in that regard than buffel? if so, could it be the couch on the banks that is protecting the banks and keeping the Todd confined to its present course?

Sands in Todd more stable than you think (re-published with Maxine Cook’s comment)
Thank you for your clearly stated answers to my questions.
It is a bit of a shame, and a continuing problem that will always need managing, that Alice Springs was built where we find it. But after 124 years we’re still here, so we must not be doing everything poorly.
I agree with you when you state that the river and the ranges are our two most valuable natural assets, but I would like to add one more – the night sky. We can’t do much about the sky except keep any industrial smoke our of it, nor about the ranges other than keep them from burning down and/or eroding. But we can impact better on the river through good management.
And that’s the key – managing.
It’s too late to pretend it will ever again be a “wild river” along the stretch between The Gap and the Telegraph Station. And above the Telegraph Station a flood mitigation dam with no allowance for a residue of standing water would severely impact on any tendency for wildness there and immediately downstream. I suggest we let it go wild again once it leaves us, and agree to manage what has become part of our shared urban landscape.
Surely there are enough people with enough knowledge living here to come up with an acceptable plan. It doesn’t have to degenerate into a rancorous climate-change type debate.

Pine Gap and Five Eyes: what did they know about COVID-19?
Charlie, Did you see the Donald on tonight’s news? If I’m not mistaken he’s suggesting people inject ultraviolet light (is that possible?) and/or a cleaning fluid.
Clearly the man is as mad as a meat axe, but he does have the world hanging on and repeating his every word.
And you say you are not amused? Chill! At least Putin is (for now?) off the hook.
China did it.
And just to clarify, I did say conspiracy theories are, or can be, amusing. That’s because they are.
I also think the flim flam man is a hoot and good fun. That’s because he is.
I did not say the death of 50,000 is amusing or fun, and it’s a cheap ad hominum misdirection from you to insinuate I did.

Pine Gap and Five Eyes: what did they know about COVID-19?
Fair go, Charlie.
You use terms like “robust form of evidence”, and “very strong indicator” to advance a theory, and then level suggestions of conspiracy theories on any other interpretation.
All I’m saying is an open mind is a good mind to have.
As for conspiracy theories, they’re entertaining. Mostly bullshit, a bit like elections, but good fun. Just watch the Golden Golem of Greatness, the great flim flam man himself. Do you really think he’s not enjoying himself?

Pine Gap and Five Eyes: what did they know about COVID-19?
@ Charlie Carter, Posted April 22, 2020 at 2:59 pm: I wish I could share your certainty that the origin of Covid-19 is settled, but I rather think an open mind here might be more useful.
As this attempt to assign culpability to China progresses, and with the emergence of quite massive legal cases gaining momentum in the US, China will defend herself.
It will be at least interesting, and possibly informative, to learn what she has to say about how and where this all started.
And isn’t it true that as new evidence emerges, scientific theses evolve? I doubt if any of this is fully done and dusted just yet.

Lucky the Town Council isn’t in the forestry business
Gnoilya, I certainly did not intend to come across as whining, more like just pointing out the absurdity of the situation.
However, since you not only misspelt my name, but also managed to miss my point, I wonder if that makes you a stationary vertical object?

Pine Gap and Five Eyes: what did they know about COVID-19?
An answer to the leading question in the above story can be found toward the end of an article found here.(When the author speaks of our government and an ABC News story, he is speaking as an American.)
“But with the horrific consequences of our own later governmental inaction being obvious, sources within our intelligence agencies have sought to demonstrate that they were not the ones asleep at the switch. Earlier this month, an ABC News story cited four separate government sources to reveal that as far back as late November, a special medical intelligence unit within our Defense Intelligence Agency had produced a report revealing than an out-of-control disease epidemic was occurring in the Wuhan area of China, and widely distributed that document throughout the top ranks of our government, warning that steps should be taken to protect US forces based in Asia. After the story aired, a Pentagon spokesman officially denied the existence of that November report, while various other top level government and intelligence officials refused to comment. But a few days later, Israeli television revealed that in November American intelligence had indeed shared such a report on the Wuhan disease outbreak with its NATO and Israeli allies, thus seeming to independently confirm the complete accuracy of the original ABC story and its several government sources.
It therefore appears that elements of the Defense Intelligence Agency were aware of the deadly viral outbreak in Wuhan more than a month before any officials in the Chinese government itself. Unless our intelligence agencies have pioneered the technology of precognition, I think this may have happened for the same reason that arsonists have the earliest knowledge of future fires.”
I consider that there have been two, and now three, seminal events over the course of my life:
1) Was there a second shooter in Dallas?
2) How did Building Number 7 collapse into its own footprint?
3) Where did Covid-19 come from
