Residents anxious, watchful over plan to blow up levee - CNN.com As we all know too well, plans don't always go according to plan, especially when Old Man River is involved," board member Lester Goodin said, according to the transcript. "It has time after time fooled people who weren't fools, people who merely miscalculated, or failed to take into account its almost infinite variables, or used inadequate models, or out-of-date models, or mistaken assumptions."
The levee was breached before, in 1937. But, Jones and Sutton pointed out, the area was heavily forested then, with trees to slow the water before it reached the second levee. That forestation is no longer there, they said. In addition, Sutton said, the explosives used are likely much more powerful today.
Deforestation, or extreme, is so bad in so many ways, and the above is just another proof.
Also, they are worried that the blast might influence the New Madrid fault, which has a potential to have an incredibly powerful earthquake. I am none too sure that would happen, however, the New Madrid fault hasn't done anything for over a century, and this is in the area of the epicenter.
