• It is important to analyze the hydraulics of pipeline irrigation system for visualizing the proper pressure distribution. In this paper, the hydraulic transient approach is presented for determining the hydraulic pressure and steady state discharges at nodes and valves. In order to develop a systematic, quick and flexible analytical procedure, an alternative to specified time intervals, namely a staggered grid, is adopted. The equation for the determination of discharges at valves is modified to calculate only steady state conditions at irregular field slope settings. An algorithm is developed which permits flexible running system. The results obtained by this unsteady flow method (UFM) are compared with the results obtained by a back step method (BSM) and the analyzing method is found to be accurate.
