Abstract

With developing and advance in farm machinery and hydraulic science, many irrigation machines invented that can irrigate a wide range of fields with high efficiency. On the other hand the limitation of water resources and the necessity of water productivity made the use of these machines unavoidable. In this research the evaporation and WIND DRIFT LOSSES of CENTER PIVOT irrigation system measured under different climate conditions. In order to determine evaporation and WIND DRIFT LOSSES according to ASAE standard, four radial lines of cans with 6 m spacing were installed. Then the amount of water in the cans, soil moisture, climate and hydraulic parameters were measured under different speeds of CENTER PIVOT system. Result showed that the average distribution uniformity during the growing season was 63 %, which indicates that this system is not suitable for the experimental site conditions. The average amount of PELQ during the growing season was 55% which shows that this system is not compatible with this farm condition. The evaporation and WIND DRIFT LOSSES were between 2%-17 percent. The evaporation and WIND DRIFT LOSSES calculated by Trimer method were much less than the measured value. This is because of not considering the effect of non-uniformity of water distribution in calculating the evaporation and WIND DRIFT LOSSES by Frost, Schwalen and Trimer methods.
