Abstract:
Field data were taken on furrow irrigations and compared with a hydrodynamic model (SRFR) which was used to predict irrigation performance. The field data were the furrow shape and slope, the infiltration characteristics of the furrow, the initial and final moisture content of the furrow, the rate and time of inflow, and the advance and recession trajectories. The hydrodynamic model predicted well the advance trajectories. It predicted recession trajectories which coincided with those of the field measurements for the upper end of the furrow but varied from the field measurements for the lower end. On the average, the uniformities calculated from observed data were higher than those predicted by the model. On the average, irrigation efficiencies calculated from field measurements were higher than those calculated with the model. Storage efficiencies for the observed data were all 100 percent because all irrigations completely met the requirement.
