A method and apparatus for head control of irrigation waters in above-ground gated pipe located on a gradient. The method includes the steps of: measuring the elevation drop over the length of said pipe; providing an in-line container at predetermined elevation drops along said pipe, said container having an inlet for receiving water from the upstream portion of said pipe and an outlet for discharging water to the downstream portion of said pipe; dividing each of said containers with a height adjustable partisan located between said intake and said outtake; and adjusting the height of each of said height adjustable partisan to provide the desired flow from the openings in the pipe upstream of said partisan being adjusted.
