48 inch pipe, how many CFS can it handle
48 inch pipe, how many CFS can it handle
(OP)
We will be rebuilding a damaged dam that was never built correctly in the first place.
The spillway consisted of a 48 inch vertical corrugated metal pipe. We have completed out hydrology but the question remains how many CFS (cubic feet per second) would have this old system been able to handle. I need to show that this system was flawed to begin with since our 100 year flood calculations come out to 906 CFS and the structure in question overtopped every few years (which should be of no surprise).

Why do you believe that the design was flawed? Just because it overtopped doesn't mean there was a flaw in the design.

TO DAMENG1: Thanks. Our Q100 is rated at 605 cfs while out PMF is at 1632 cfs. The CMP was woefully inadequate from the get go. Goes to show what happens when you don't listen to the professionals!
