Water Resources: Hydraulics and Hydrology--
Q ..
It would keep them busy for a long time, wouldn't it?
A ..
Keep them busy, but it may just wipe out one structure. Then the water all goes through
that one structure. Miles and miles of the main levee may still be intact so all you have
to do is replace that one expensive structure. You don't have to redo the whole reach
because once it gets through, it's going to keep coming through that same location.
Unfortunately, the structures that are there cost a hell of a lot of money.
Q ..
From one of my discussions, General Heiberg was on it in that `73 flood. He told me
when he was up there, he thought that thing was going.
A ..
You stand on the control structure? with all that water going under it, and boy you worry.
I was on it, too.
Q ..
He said it was just bouncing up and down.
A ..
And you see the big boulders that they dumped in there and they just went right on
through--trying to fill up the holes. The flood dug a real scour hole underneath that
structure. They wondered what the hell was holding it there.
Q ..
Well, one end was completely undercut.
A ..
Underneath the structure was an awful big hole. So after the flood went down enough,
they started dumping concrete in there as much as they could. Rutting it in and putting it
in. But they've got another control structure there now. I think the Auxiliary Control
Structure is finished.
Q ..
So they actually have two of them.
Two of the majors, plus the Morganza floodway. Then the Old River floodway upstream

from the control structure.
Forecasting and Estimating Flows
Q ..
When you look at hydrology, you mentioned that you study river basins and systems. In
the Corps you have an awful lot of them to study or to analyze. We've talked about the
