Interesting. So apparently there’s belief that the original failure point was caused by the failure of a particular slab not the dynamics of the curve in the spillway.
I find all of this interesting and worthwhile.

Exactly. See post 1,745 on the extensive fluid flow replica model lab testing. Only a super critical bend would risk a failure mode (i.e. inducing cavitation & great turbulence). None of these conditions have been observed even in the higher flow rates of 100,000cfs. The water exactly follows the results of the hydraulic model testing.
