    This is not the usual "hey look at this guys" thread. With the Mississippi floods threatening the spillways what level of repairs will be needed after the floods subside? Just a question about repair guesstimates, probable disruptions and general effect on the economy.

    It depends on what you mean by repairs, and what is to be repaired. If it is the spillways themselves, ACE will have to inspect Old River Control, the Morganza spillway and The BC spillway after the event is over for any structural or geotechnical damage. Some is expected (scouring, gate damage) but they would then have time to repair it. for the fuse plug/blown levees, they will require rebuilding.

    For areas flooded due to the spillways, it will be silt cleanup, standing water pumping, and alot of debris removal. The ACE will be the lead agency on this, but remember the people living withing the spillways/flood plains knew this could happen, the ACE may just decide to not renew the easments that allow them to live within the levees, especially in the Atchafalaya flood plain.

    I'm more concerned about the reassuring comments being made about the spillways not giving way. Levees and spillways south of Baton Rouge giving way is not a major immediate problem for the rest of the country but giving way north of Baton Rouge will screw up the economy from from southern Alberta to the Gulf and western New York to eastern Idaho. How long will it take to straighten that out? And how bad are likely knock on effects?

    The spillways are designed for the flow they can take in. The real fear is that not enough flow will be diverted soon enough, and the mainline levees will start failing. That is the real issue.

    So much of the media reporting on this is either wrong, very wrong, or completely wrong. The structure they talk the most about, Old River Control, is actually 4 structures, all desgined to keep the MR in its current basin. The use of spillways is not only to prevent levee failure, but to keep this structure intact.

    By Obamas definition of stimulous this should stimulate the economy. However we know this to be untrue.

    Quadruple redundancy is good, how about Morganza?
