I was schocked to see the New Orleans Levees on CNN.
In Holland the most populated land lies till 30 feet below sea-level. After severe storms in 1953 many levees (dijken) blow away. Many people drowned. We decided to rebuild the levees and put all the knowledge we had in our levees. Millions of people would be drowned now if the levees would break. From the moment I saw your New Orleans levees it was clear to me that they never could withstand the water. You can’t let people live behind such levees. I don’t know if there is enough knowledge about levees in the United States, if not, I would immediatly contact the Dutch authorities to see what they could do for you.
Half a million people behind such levees is a criminal act.

In an article about Shell’s oil shale experiments the technique they used to prevent the contaminated waters from the extraction process from leaking into the water table was to freeze the walls of the chambers (ice is impermeable to water turns out, so long as it stays frozen).
This has me thinking that a possible fast temporary levee breach patch could be done using refrigeration units to create a temporary ice dam that could withhold the constant erosion of the water pressure so long as you keep it frozen.
There are probably physical limitations I haven’t considered as to why that method hasn’t been tried, or maybe someone who knows something can tell me why this would or wouldn’t be possible.

Everything you ever wanted to know about the advanced levee systems in Amsterdam and London, unless you’re a civil engineer and want the hard math. Noah linked to this article a few days ago.
With a price tag of $8 billion over 25 years, though, I’m afraid that Congressional amd political machinery that cut out preventative levee work in the first place are going to mean that we shall pay any price and bear any burden for such a system, as long as it isn’t too expensive or too difficult.

This is not the fault of the corp of Eng. Those guys are top shelf and when it comes down to it they never do anything that they are not asked to do by the civilian govt.
As to New Orleans and other flood planes. I see no reason for the average person to be allowed to live and work in a flood plane. There are businesses (Agro, ports, pertoleum and gas storage and piping center) that are always going to need to be in flood planes, but schools, homes, malls, govt. builds, stadiums, etc are just silly. If people for the most part did not live in the flood planes then most of this problem would not exist.

I read about the interlocking systems that are filled with dirt,sand etc. I would think that time is a factor when you are setting these systems up and putting in sand and dirt would would be time consuming. First you have to have the manpower to bring in the sand or whatever. Then you have to have the manpower to fill the containers. I would think that if you had containers that only needed to be filled with water would be better and quicker. I would think that when a section of the levee fails something that is similar to a barge could be brought in and sunk in place would help plug the breach faster than so many sand bags, but what do I know.

Yeah, but they don’t have to deal with hurricanes in Holland. I imagine it makes there work a little easier.
