Mood: Somber
Listening to: A Fugue by J. C Bach
This is terrible disaster. The scene of death and
destruction on the BBC news make the US appear to be a third world
country. I know that the US has the capability to solve the
problem. However, it is important to act quickly.
The US is renowned as the place where "great things happen fast".
Now is the time to show what they can do.
The measure of their success is the number of deaths and the amount of damage.
See the bottom of this article for other measures.
IT IS TIME TO ACT!
Here are the steps required
1. Getting Food Water, Supplies and Medical Aid to the People.
Supply all the needed food and material to the people stranded.
This requires that the food/water/medical aid be transported to the area.
1.1. Air Transport.
The US Airforce have the equipment to transport the supplies by air.
1.2. Water Transport.
There are plenty of boats of all sizes that can be used to move the supplies to the stranded people.
1.3 Transportation Organization
Federal Express have
the best logistics organization in the world. They have the
organizational ability to ship millions
of packages around the world ( in 36 hours of less).
I am sure that they could
have all the supplies delivered in 48 hours. They just have to be
asked.
2. Stopping the Flooding.
To deal with the flooding you have to do the following:
2.1 Seal the breaches.
2.2 Pump out the water.
3.Health Issues.
4. Risks
5. Preventing this from happening again.
6. Measuring Success.
The details.
Let's take each part in turn.
The total length of the breaches is less under 1000 feet.
2.1 Create a Barrier
The first task is to create a barrier. The quickest way
to create a barrier is to make a barrier of I-beams at 10
feet spacing and then put steel plates, standing on edge,
against these I-beams to form a wall. The I-beams will keep the
plates from moving due to the pressure of the water.
2.1.1 Placing the I-beams.
Using a helicopter, take a 30 ft. I-beam and drop it, like a spike, where the breaches have occurred.
By adjusting the height from which you drop the I-beam, you can control how deep the I-beam penetrates into the ground .
My guess is that the correct drop height is approximately
100 ft. However, dropping a few I-beams will allow
the optimum height to be determined quickly.
This is an opportunity for some company to show what wonderful engineering then can do.
Think of advertising potential! The world-wide
news coverage and associated advertising and goodwill that this work
will generate will be priceless!
The goal is to have about 15 feet of the I-beam sticking up above the water level.
this will ensure that it is high enough for protect from
future storms. One can add more steel plates, where required, to
make a barrier of 20 feet or more later on, when this immediately
disaster has
been addressed.
By spacing these I-beams 10 feet apart, one can make line
of I-beams which jut out of the water. The will look from afaw
like toothpicks on a watery beach.
2.1.2 Placing the Steel Plates.
Next, take steel plates, 10 feet by 20 feet, and lower them into the
water so that when the plates are stood on edge the water
pushes the plates against the I-beams. This
will provide a quick barrier that will reduce the flow of water
dramatically.
Alternatively, the steel plates may dropped from 10
ft so they will sink into the ground stopping leakage under the
plates.
2.1.3 Stopping the leaks with smaller malleable plates.
To handle the leaks one can take steel plates of 1/4 - 1/16 inch
and place them to cover the spaces where the larger plate overlap. The
water pressure will 'stick the plates over the leaks'. This will
further reduce the flow.
2.1.4 Flexible cloth - to seal the cracks.
Take Tyvek ( or fiberglass/carbon fibre or some strong flexible fabric)
sheets and lay them over the other sheets to stop the flow
completely. Once again, they are placed on the water side so the
water pressure forces the material into the holes to seal it.
Epoxy or silicone or glue can be place on the sheets before they are placed to complete the seal.
2.1.5 Completely Sealing the Barrier.
Using boats and divers one could perform the other work to completely seal the levees.
I am confident that there are hundred of companies that could do that work in a day.
If only President Bush to would ask them.
2.3.1 Speed of Deployment
2.3.2 Time to Place the I-beams.
This approach is rapid - I estimate that 4 helicopters can
place 10 I-beams in 1 hour. This would cover a breach
100 feet. So in 16 hours one could have a breach
of 1600 ft staked with I-beams.
2.2.3 Time to place the Plates.
I estimate that a team of 20 men and 4 helicopters could place
four 10 x 20 ft. plates in 1 hour. So one could seal
about breach of 80 feet in 1 hour.
So in 16 hours one could seal 1200 ft.
From the TV pictures this would solve the breach and reduce the flow to 1%.
2.4 Dumping the area dry.
The next task so to pump out the area.
2.4.1 Using Commercial Pumps.
This can be done with commercial pumps. Many construction sites have pumps which can be
rented.
2.4.2. Powering the Pumps.
Some run on Gasoline or Diesel oil. Many others are electrically driven.
The helicopters can fly in electrical generators to operate the electric pumps.
One can run thousands of pumps and this will empty the flooded parts of the city quickly.
2.4.3 Restoring the Electrical Grid.
Obviously, if the power companies get electrical power restored
to the city this will allow electrical pumps to be used.
Time is of the essence!
3. Stop the health risks.
3.1. Stopping Disease.
It is essential to get the dead bodies sealed to stop disease. This is where
plastic body bags would provide an quick solution. the goal is to provide care
for the living and injured .and stop the spread of disease.
3.2 Supplying Water and Food.
Supplying bottle water and food is the next task. Large companies like Coke
can supply all the bottled water required.
Other large companies can supply the food needed.
Alternatively, the US Army/Navy/ Airforce have stockpiles of
rations that can be used if needed.
3.3 Shelter
For shelter - many organizations have the capability to create tent camps.
The current delays do not look good. There should have been few deaths.
Every death is a red flag that the U.S. has problems.
4. Risks
4.1 What about risk from the shooting?
I am sure that the shooting will stop when the people come to do the repairs.
In any case the U.S. army and National Guard have the training to stop the shooting.
5. Preventing this from happening again.
When all the breaches have been stopped one can use this barrier
as a framework and build a cement cladding on the outer face.
6. Measuring Success.
Engineering is a measurement based profession.
Timing is important.
The right task performed too late is the wrong task!
I suggest that a good measure of the effectiveness of the effort
is by looking at indicators.
I suggest that there are some useful indicators:-
1. Death toll after 1, 5, 10, 15, 20 , 30, 60, 90 days.
2. Number of days until barrier is completed.
3. Number of days till water level drops 1 feet.
3. Number of days till water level drops 2, 3,4,5 , 6, 8 , 10, 12 ,14 ,15 ,20 feet, completely dry.
4. Number of days till power is restored to pumps. 10%, 20%, 50% 80%, 100% of city.
7. Number of days till health risk due to sewage etc is reduced to pre-flood level.
8. Number of days till phone service is back to normal.
9. Number of day till water is restored to 10%, 20 ... 100%.
One can measure the old water consumption levels and calculate the water flow.
(Assuming that noone cheats by pumping water directly into the sewer to pretend that
all the service has been restored! By looking at the hourly water demand one will be able
detect such cheating.)
10. Number of days until all streets are open for traffic.
11. Number of days till tourists return. (Sales of toilet rolls and Coke etc.
can be used as indicators of the return to the old level of business).
12. Electricity power consumption can be used to measure the adjustment to normal.
(President Bush can use these to show what a good job he has done at handling this crisis.)
If you think that this should be forwarded to someone who can help, please do so.
Any comments and suggestions are welcome.
