Water Resources: Hydraulics and Hydrology
reservoir, instead of assuming the most critical condition, as was done for hydraulic
design. I think that's what he had in mind. Did he make any specific comment? He said
he had a lot of problems.
Yes, I think that's basically what he was doing and what he was talking about.
A:
All right.
I was just wondering when it passes over from hydrology to hydraulics. What kind of
consequences did you have to consider?
If Vern had been successful in determining the reservoir sedimentation level for a spillway
design flood, that level would have been used in the hydraulic design to determine the size
of spillway and height of dam required to pass the maximum possible flood. Model tests
indicated the difference to be relatively small, so the worst sedimentation condition was
assumed for design.
On the conservative side, then?
That's right.
Was there anything else about the Arkansas-Red-White that you can remember?
No, not specifically. That was quite awhile ago.
In the design of locks or dams--the other day we talked about tainter gates and vertical lift
gates in various types of dams.
Yes.
Q ..
I've also noticed that the Corps has built roller gate dams and these double-lift gates, and
this is what we were talking about the other day.
apparently has double-lift gates.
A:
That's right.
