Özet

This study examined the trends of monthly and annual potential evapotranspiration (PET) values ​​between 1965 and 2018 at Erzincan, Bayburt, and Gümüşhane meteorological stations. Spearman's Rho, Mann Kendall (MK), and Sequential Mann Kendall (SQMK) methods were used to determine the trends. The Hargreaves equation was used to calculate the PET values. As a result of the study, according to MK and Spearman's Rho tests, while increasing trends at 95% and 99% significance levels were dominant at Erzincan and Bayburt stations, no statistically significant trends were found at Gümüşhane station except February. According to the SQMK test, an increasing trend of 95% was observed in all periods at Erzincan station, except for April, August, and December. In the Bayburt station, increased trends at the level of 95% importance were determined in the periods except for January and December. While increasing trends at 95% significance level were dominant in February, October, December, and annual periods in Gümüşhane station, no significant trends were found in other periods. According to the findings, significant increases were detected in PET trends at Erzincan, Bayburt, and Gümüşhane stations. For this reason, the importance of taking measures against the decrease in agricultural production in the study area and effectively managing water resources was emphasized.
