Hydraulic Grade Line
Hydraulic Grade Line
(OP)
I am designing some storm drain pipes but I have difficulty to find the right hydraulic grade line for those systems. I am designing with circular and elliptical pipe. I would like some help could be some tips, information of how to do it. Thank you





RE: Hydraulic Grade Line
If you are designing a new system connecting to an existing system then I usually reanalyze the entire system. If this is a stand alone new system then the analysis is straight foward. Sounds like this is first time designing a storm drain so I will point you to a step by step procedure, HEC22. Go to FHWA's website and download HEC22 pdf. It will be a great help.
RE: Hydraulic Grade Line
Are you having a specific problem or just don't know how to do the analysis? If it is a specific problem or issue please clarify your question. If you don't know how to start, I think that the agency or your client would expect that you have some expertise before designing a drainage system based on teaching yourself from a book. If you haven't done this type of engineering analysis before you should be working under the supervision of a licensed engineer, who should be able to help you, or hire a qualified consultant. HEC-22 is a great reference, but here in Washington (and I assume the other states as well) our state code requires that engineering analyses are supposed to be overseen by a qualified (i.e. experienced) and licensed engineer.
Good luck!
