to stop the breaches holes |
Hello
I send again that post to the group, adding other groups, where I hope
somebody is certainly able to make it following toward government people in
charge of the works on the breaches of
the levees, and to the Army Corp of Engineers.
I sent this post on 31/08/05, answering the post "massive hole in the levee"
but it did not create any remark, or critics.
I am engineer and sincerely I think the way I suggest to stop the breaches
can easily be down to work.
And you have not any time to waste.
The dicussions about human responsabilities are, at the moment, time wasted.
I think that the best, unique and easiest way to plug the massive hole in a
levee that burst on Tuesday is that mean:
to set long stakes by the way of an helicopter which would next leave them,
vertically, to get them in the ground, from an heigth defined by few direct
experiments on the levee.
The positionment of an helicopter is common, and precise with help of GPS.
Helicopters are already commonly used to built electricity pylons, obviously
by a light deposit on position.
The stakes can be old electric reinforced concrete pylons, as well as old
wood pylons of phone lines for exemple, as well as old rails of railway. As
well as new trees ready to be
transformed in boards, or even now cut just for
that use. It would be as good using stocked new pylons. taking in account
the growing coast of the
entering water .
After one or two rows of positionned stakes, some old cars can be placed
upstream. Numerous cars on the flooding zone can be used for that.
The use of helicopters allows numerous possibilities, if trucks and
materials cant be driven directly on the levees, they can be positionned
not far the working zone.
We have seen at TV, at the moment of the first Golf war ( or between the two
wars )an army
demonstration of an helicopter, or a plane) leaving such a concrete stake,
just with a little metallic conic point.
The stake penetrated a huge military concrete shelter as it was a butter
clod.
Ask the US army archives about that fact. Army also can give help with its
numerous big helicopters.
The levee are generaly made of ground so the woodden stakes even will
easily
penetrate in a vertical position to quickly create a vertical barrier, a
first anchor on the ground next
reinforced with horizontal stakes and stones and any disponible thing, and
late
with earth.
With the means of your army a 500 feet wide breach would quickly be closed.
Sincerely sorry for that disaster.

Massive hole in levee is major challenge for engineers
http://www.duluthsuperior.com/mld/duluthsuperior/news/nation/12517242.htm
BATON ROUGE, La. - (KRT) - Federal engineers now face the challenge of
plugging a massive hole in a levee that burst on Tuesday, adding to the
misery that Hurricane Katrina inflicted on New Orleans.
The 26-foot-deep, 500-foot-wide breach in the 17th Street Canal sent
flood waters surging through an estimated 80 percent of the city.
With many people still stranded in the flooding, Tuesday's break
compounded the area's problems.
Officials said fixing the breach is their top priority after saving
human lives.
"You've got to stop the bleeding before you fix the wound," said Mark
Lambert, spokesman for the Louisiana Department of Tranportation and
Development.
Although the hurricane had passed, Gov. Kathleen Blanco said the water
in New Orleans was still rising.
Col. Jeff Smith, Louisiana's deputy director of emergency management,
said the U.S. Army Corps of Engineers hoped to fix the break as soon as
Tuesday night or Wednesday.
The plan is to load large metal containers resembling truck trailers
with heavy sandbags and rocks and drop them into place, like a cork
stopping a bottle, Col. Smith said.
He said officials were still evaluating the plan, trying to ensure that
the weighted-down containers could hold back the floodwaters and would
not cause more damage.
State officials said they had located two other breaches while flying
over the area to survey damage.

They were the ones who built New Orleans on land below sea level. :-)
False. Two thing led to the sinking of New Orleans. One was the control of
the Mississippi by the Corps of Engineers which prevented new silt from
building up the land year by year to replace losses. Now it silts up the
river and thus the river keeps getting higher and higher. The other was
the
pumping of ground water which caused a general compaction of the silt.

I did reply to you pointing out that it was too late to stop the flow as the
water
on both sides of the levees was now equal. Therefore the easiest way to
block the breach is to fill it from the sides. That evening on the BBC news
programme helicopters were shown dropping sand bags in the water, and
trucks were shown driving along the levee up to the waters edge to dump
fill from there. Either they have taken the advice from both of us, or they
(like you and me) were engineers and worked out for themselves what to
do.
HTH,
Cheers, Alastair.

By the way wood floats.

Gravity, all that development of ground-penetrating bunker-busting bombs
might as well get put to some constructive use. However, laser-guiding
the stakes might cost more than just hammering them in the conventional
way...

Bunker-busting bombs would change them into matchsticks. The
technique is to point the ends using a gigantic pencil sharpener. Then
you fly over the breach at a great height and drop them pointed end first.
The problem then is to get them to fit together in a watertight fashion.
Perhaps
if you strapped them together using large rubber bands, and dropped them
altogether, that would work.
OTOH throwing sandbags off the end of the levee into the breach might
be a lot easier.
Cheers, Alastair.
