Do not forget the client. As we speak we dealing with a client that want as cheap as possible work done. And believe me, that opens the doors to all sort of problems. When we sit in meeting with them, they keep throwing the issue of "they can get anther company to do it" on the table. My answer...
We call trenches silent killers. We loose around 50 % of jobs due to safety built into our cost. But rather that, then your name in the mud and the fact that sloppy and cheap work killed your workers. We shore anything that's above knee deep. If you think we overkill, go make your own...
Well, if this was now my job, I would do the following. First off to my computer. Take the current spillway design and load it into a amazing program called 3D-FLOW (I am not working for them, heheheheh)and draw profiles at different flow rates. Then get the optimum design pattern which give...
Watch some youtube videos and they mention that it cost some 20 M to do the job. Ouch. My business is surely on the wrong continent on planet earth. It would have taken us three days of scanning, drilling and restricted blasting to do this job. And if they paid us only 4 M, We would have smiled...
My 2 cents.
Two issues I have with this design or rather, end product. sometimes the design and end product separate paths due to financial issues.
The emergency spillway seems to be more or less at the same height as the whole area where the parking area is. What bothers me about this.?

Just a observation from studying the various photo's ,it is clear that the composition of the material in that hill is not stable, nor solid granite. So whatever one built on top, will need a solid man made foundation. I agree with a previous poster, now it is time to redo that whole Shute. With...
I think way back people at projects from a different angle as what we do today. Seen it in some dams built by Even large foreign companies in AFRICA. The project was kept within the budget, no matter what come up. Then 20/30/40/or like in the case of KARIBA, 60 years later, it become somebody...
Oldest, We are on the same page. Agree fully what you say,that the whole bottom part must be redone and serious attention to the base material before a new slab is cast.
To Oldest, the base would only corrode if the concrete on top is damaged,but it provide a much more stable foundation as what bedrock is. its not the 8 feet of water thats the problem. its the tiny air bubbles in the water that cause cavitation. In the past many believe cavitation is a minor...
Looking at the whole picture, I put my money on cavitation and some sloppy engineering design.
Let us keep Bernouli on the side for the moment, and bring Uncle Newton in. That area is below the curve in the spilway. The water want to continue straight, but eventually gravity will win,slamming...
