Multi-objective fuzzy optimization model for the determination of furrow surge irrigation parameters

In view of the small quota of irrigation by collected water, multi-objective fuzzy optimization model was established based on field experiment data andfuzzy modeling techniques. A combination of parameters for optimization ofirrigation was gained by the solution of this model, i.e. in cycle of 15 minutes water supplying, 15 minutes stopping and 1 L/s water flow rate of entering into furrow. It was shown that the irrigation quality indexes predicted by this modelwere close to those measured in the field experiment and that the comprehensiveirrigation quality effect produced by these parameters was satisfactory. The results of this paper provide an effective irrigation plan for the surge irrigationarea with small quota of irrigation water. Also, this paper provides an effective method for determination of technical parameters of surge irrigation.
