Global Uniformity of Trickle Irrigation Systems

ABSTRACT Asimulation model for the study of trickle irrigation uniformity was developed which treats the various equipment, system and other factors known to influence emitter flow rate variation. The model provides a tool for the assessment of global trickle uniformity in the sense that the assessment need not be spatially or otherwise restricted. A number of simulations were made to determine the sensitivity of global trickle uniformity to each of the determining factors. Emitter plugging, the number of emitters per plant, and emitter manufacturing variation are the most significant factors influencing the uniformity of trickle irrigation systems..
