I've designed some irrigation ditches for a large farm project. The specified slopes range from 0.03% to 0.07% - very flat. The contractor has told me that even with GPS and lasers, that he won't be able to meet these grades.
From other designs and guidelines I've seen, slopes this flat are...
I am trying to analyze the capacity of an old ditch with some sections that have uphill slope (uphill = negative slope). Without using any modeling software like HEC-RAS, what are some ways I can estimate how much capacity we are losing in these sections? Assuming I have all the...
Hello all,
I am specifying 15-inch plastic irrigation pipe (P.I.P.) for an agricultural irrigation project. Contractor is telling me that 15-inch butterfly valves don't exist(according to his vendors). I understand 15-inch is a bit of an odd size, but I find it surprising that a major PVC pipe...
