The model AVALOC aims at design and performance analysis of micro-irrigation systems, adopting the sector as the unit for analysis. Model computations are supported by a database on the emitters and pipes, and the sectors being designed or evaluated. In the design mode, the model provides for the selection of pipes and emitters that permit to attain a target performance. In the performance analysis mode, a hydraulics simulation is executed and several system performance indicators are computed. The present paper introduces the model, mainly oriented for the evaluation of systems under operation.
