Sporadic E is the Earth's aluminum foil beanie for the 'global warming' sheep.

I seem to remember that they were supposed to be maintained using parish funds, but the funds were diverted elsewhere.

Likewise in the Minneapolis bridge collapse.

Designed and built by C of E, inspected and minor maintenance by local Levee Board, major maintenance by C of E. The Levee Board was more concerned with running casinos and marinas.

The Minneapolis Bridge was in the process of being repaired and upgraded when it collapsed. I don't know if a final "smoking-gun " cause report has been issued.

In IA it was 35' above "flood stage". It looked from the pictures that the Des Moines river was a good 30'-40' above what I remembered it as being in March when I was there.

Doesn't work that way. It didn't only rain on the rivers. That water came from the entire state and a few around them.

Different geology entirely. Even you admitted the state was mountainous except for the cities by the river. They only had to protect a small strip. Not wall an entire state's worth of water in the river's channel.

The subject wasn't a cess pool like New Orleans.

...which hels a lot (volume), though the Muddy is pretty wide too, it is *slow* (no drop).

Perhaps getting to this thread late... But last time I looked at 100-year and 500-year datasets, they had the letters "FEMA" associated with them.

As such (and being from hurricane-central), I have to accept these numbers with no small amount of skepticism.

Statically speaking, I would say FEMA has no clue.

I think those designations existed before FEMA.

Not that i know of, but the workplace has been very ugly of late. Way too many false "hard" deadlines. All in the past two weeks.

Built yes, maintained no. That is transferred to the locals who typically will not. They "need" the money for various tax relief schemes.

It would be an interesting exercise to take current aerial photos of the flood damaged regions and overlay them against the 100 and 500 year flood data.

I've never had to do actual physical sandbagging before (in the literal sense, that is. Ha!!) For towns at risk, don't they also have to do something with the sewer/ storm drains? Wouldn't the water "back-up" into town? Or do they have valves for these things?

-mpm

It isn't legal to have a sewer dump directly into any stream... at least in most of the US. Here, in AZ, sewer is processed in a plant which then outputs water usable for irrigation.

We don't have storm drains in AZ, other than for reaching retention basins; although Scottsdale's greenbelt dumps into the Salt River, which is normally dry. We don't have "floods" in AZ, just "run-off" ;-)

I'll post some pictures of our local park.

But I think back-East-style storm drains can be closed.

AFAIK, our storm drains run to the river, seperate from the sewer system.

I suppose in an arid place like Arizona, city engineers could care less about installing two systems (flash floods aside).

I'll get out sometime today and take pictures at the park down the hill from me.

Our storm drains are entirely different from back East... we tend to get enormous, but short, rainstorms.

So we use local retention basins to return the water into the ground water table.
