The rational use and conservation of water resources require that irrigation performance, including emission uniformity, be as high as possible. Simulation models can help achieve these objectives. The AVALOC model has been developed for design and performance analysis of microirrigation systems, adopting the sector as the unit for analysis. The model works with the Windows operating system and is explored interactively through a simple dialogue structure consisting of a sequence of user‐friendly interfaces. Model computations are supported by a database containing updated information on the emitters and pipes available on the market, and where the information relative to the sectors being designed or evaluated is stored. The databases allow easy introduction, visualization and correction of data through a user‐friendly menu. In the design mode, the model provides for the selection of pipes and emitters that permit the attainment of the target performance, including emitter discharge uniformity. In the performance analysis mode, a hydraulics simulation is executed and several system performance parameters are then computed. The simulation can be performed using data created during design or data collected from field system evaluation. The present paper describes the main features of the model and shows a design example applied to an olive orchard. Copyright © 2001 John Wiley & Sons, Ltd.
