Re: New Orleans Pumps: New Orleans flooding may last for days[sic] |
Hello
I send again that post to the group, where somebody is certainly able to
make it
following toward government people in charge of the works on the breaches of
the levees;
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 leave them,
vertically, from an heigth defined by few direct experiments on the levee.
The positionment of an helicopter is common, and precise with help of GPS.
The stakes can be old electric reinforced conctrete 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 as 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 will easily
penetrate in a vertical position to quickly create a vertical barrier, next
reinforced with horizontal stakes and stones and any disponible thing, 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.

Hello

make it

the levees;
It is too late for that. The water is the now at the same height on both
sides of the levee, and the bursts can easily be filled by driving
dumper trucks along the top where it has not been breached.
So now you have to think of how you are going to get the water back
over the levees, when all the pumps that did that job are beneath the
water :-(
Cheers, Alastair.

The plan for that seems to be to run Lake Ponchartrain down to sea level
(open the outlets ) until it is below the majority of the city and then
breach the levees to let the city drain ( except for those areas which are
below sea level.) At this point, the pumps should mostly be above water ( or
can be diked ) and can be repaired and brought online to pump out the rest
of the city while the levees are rebuilt.
Cheers, Alastair.
