Mann-Kendall and Sen Slope tests were employed during the trend analyses.Findings: the results indicate that linear trends are positive for all stations except Bagh Tangheh during the study period. According to the Mann-Kendalls and the Sens slope tests results, increasing trend of data was significant in Kamarkhani station at level of 95% and in Aliabad - Lavarak station at the level of 99.9% .
