Abstract
To investigate the main and interactive effects of various meteorological parameters on the rate of evaporation from the water surface, variance analysis was used. Based on the analysis, all the mentioned parameters had a significant effect on the rate of evaporation. Eta squared for the main effects was 0.69, indicating that the main effects could estimate 69% of the output variance. Based on this parameter, the amount of solar radiation had the most significant effect on the rate of evaporation, followed by surface pressure and relative humidity. The results of variance analysis considering the interactive effects showed that all the interactive effects had a significant effect on the rate of evaporation, and only the interactive effect of wind speed and radiation was not significantly different. The interactive effect of surface pressure on temperature and radiation had the most significant effect on the rate of evaporation, followed by the interactive effect of temperature and relative humidity. Investigation the effect of various meteorological parameters on the rate of evaporation from the water surface and their interactive effects can be used to investigate the efficiency of various methods to reduce evaporation.
