fel3, I think you've nailed it. Talking with some other engineers at other municipalities, the consultant decided to show that the depth of flow is still under capacity for their proposed upstream development. I was told as long as the HGL is contained in the pipe, then theoretically you can...
I’m working under a P.e. And we are the approving authority for the municipality. I usually meet with our P.e. To discuss the developments but it is not due for a while. I just did not understand how you can argue the surface outlet water elevation if the mannings show the pipe section can not...
I'm reviewing new developments for sanitary sewers. Usually I've seen sanitary sewer analyzed by capacity, using mannings (pretty simple). But I have a developer providing computation for an existing over capacity pipe section. They are providing inlet water surface and max water surface...
