“…For this purpose, various trend methods are used, both parametric and nonparametric, as well as providing statistical and graphical evaluation. For the past few decades, methods such as Mann-Kendall (MK), sequential Mann-Kendall (SMK), Spearman's rho (SRho), Sen's t, Sen's slope, linear regression (LR) and cumulative sum (CS) have been common in determining trends in hydrometeorological time series (Makwana et al 2020;Koycegiz and Buyukyildiz 2021;Patakamuri et al 2020;Shahid 2011;Yenigun et al 2008;Yue et al 2002). Rahman et al (2017) examined the annual, monthly and dry season precipitation trends of Bangladesh and found no significant trend in annual mean precipitation and dry season precipitation for the whole country, while increasing and decreasing trends were obtained in long-term monthly precipitation.…”

The Euphrates–Tigris River Basin (ETRB), one of the largest river basins in the Middle East, is also among the most risky transboundary basins in the world. ETRB has a critical importance for the region both politically and economically due to its location. Evaluating the increasing regional impacts of climate change is even more important for the sustainable management of water and soil resources, especially in transboundary basins such as ETRB. Türkiye is one of the most important riparian countries of the ETRB and the Türkiye part of ETRB constitutes the headwater of the basin. In this study, the temporal variability of the annual total precipitation data for the period 1965–2020 of eighteen stations located in the Türkiye part of the ETRB was investigated. Classical Mann–Kendall (MK) test was used to statistically determine the monotonic trend of precipitation. In addition to the MK method, analyses were carried out with three innovative trend methods, which have the ability to interpret trends both statistically and graphically. These innovative trend methods are Şen innovative trend analysis (Şen-ITA), Onyutha trend test (OTT) and trend analysis with combination of Wilcoxon test and scatter diagram (CWTSD). The results obtained show that there is a decreasing trend in annual total precipitation in ETRB according to all trend methods generally used for the examined period. In addition, the results obtained from the relatively new OTT and CWTSD methods show strong consistency with the results of the other two methods. The advantages such as performing numerical and visual trend analysis with innovative OTT and CWTSD methods, identifying trends in low–medium–high value data and detecting sub-trends have shown that these methods can be used as an alternative to the widely used MK and Şen-ITA.
