%0 Journal Article %T Comparison of Mann-Kendall and Sen¡¯s innovative trend tests on measured monthly flows series of some streams in Euphrates-Tigris Basin %A MURAT AY %J - %D 2018 %X Low, medium and high values of a variable are a significant issue in hydrological, meteorological and climatological events; moreover, these values are used to decide various design parameters based on scientific aspects and real applications around the world. In this context, a new trend method recently proposed by £¿en was used for monthly streamflow data recorded at two different stations (2174- Murat River (Akkonak) and 2634-Garzan Creek (Kozluk)) in Euphrates-Tigris Basin. The Mann-Kendall trend test was also applied to the same data. It was seen that the stations had statistically significant decreasing trend according to the Mann-Kendall and £¿en trend test at 95% confidence level; moreover, the proposed method provided an important advantage in terms of graphically evaluation of low, medium and high values of streamflow data %K F£¿rat-Dicle Havzasu %K Mann-Kendall %K Ak£¿m %K £¿en¡¯s trend test %U http://dergipark.org.tr/erciyesfen/issue/37078/406818
