Abstract

THE hydraulics of a moving-plug gated pipe irrigation
system are analyzed. A relationship was developed
for predicting orifice discharge coefficients for a range of
typical pipe flow velocity and head conditions. A simulation
model was developed to predict the time distribution
of orifice flows, the distribution of infiltrated water
across a field, and runoff rates. The model can be used to
design cablegation systems for fields having variable pipe
slopes and variable furrow lengths. Orifice sizes are
varied along the pipe line and the plug travel speed is
varied in order to obtain optimum net water application
for all furrows and to keep the furrow stream sizes within
acceptable limits.
