Sorry about this off topic post, but I am not sure where else to ask.

I am looking on the web for more photos of the New Orleans levees to
better understand how they were built.

Here are a few links that will help in your research:

How they were built is not as important as what they were built on and
what they were designed to do. Just as an airbag is not a guarantee
that you won't die in a crash, a levee is not a guarantee that water
won't top it or topple it.
