Abstract

Optimized management and utilization of any system requires knowing the working conditions of the system, and optimized utilization becomes possible by evaluating the way the system works. Since various regions in Iran have arid and semi-arid climates, obtaining the actual WIND DRIFT AND EVAPORATION LOSSES and also making optimized use of water has a great importannce. The present research intended to evaluate a classic semi-permanent sprinkler, to measure WIND DRIFT AND EVAPORATION LOSSES, and to introduce an optimized model by using MULTIVARIATE REGRESSION for the study region. The study was conducted in Part of the Moghan agro-industrial complex in Ardabil province at WIND SPEEDs of 0-3 and 3-6 and higher than 6 meters per second with three replications. Results in ADF 25º nozzle sprinkler model indicated that the efficiencies of the system at WIND SPEEDs of 0-3, 3-6, and higher than 6 meters per second were 82, 66, and 43 percent, respectively, and WIND SPEED, temperature, relative humidity, nozzle diameter, and vapor pressure deficit (saturation deficit) were among the factors that influenced WIND DRIFT AND EVAPORATION LOSSES. The wind factor had the most and vapor pressure deficit the least effect on WIND DRIFT AND EVAPORATION LOSSES. Furthermore, the equation of the best fit line to the measured values for WIND DRIFT AND EVAPORATION LOSSES under the prevailing atmospheric conditions in the region was as follows and the difference between results of the model and observed data was not significant in 1% level of confidence. Moreover, the measured and the modeled percentages obtained for WIND DRIFT AND EVAPORATION LOSSES varied from 6 to 34 and from 11to 35 percent, respectively.
