This research, identify the long-term temporal trend and magnitude (m3/s/time scale) in monthly, seasonal, and annual streamflow by employing three non-parametric approaches conventional Mann-Kendall (MK), Innovative-?en trend (I?T), and Sen-slope (SS) on 5% level of significance. The monthly streamflow data of 32-years (1976�2007) were recorded at Naula and Kedar stations positioned in the upper Ramganga River catchment (RRC), Uttarakhand State (India). Results of scrutiny reveal a significant negative trend in 17 time-series was detected by conventional MK test, and significant positive/negative trend in 1/30 time-series was inspected by the I?T method with changing magnitude over monthly, seasonal, and annual scales at both stations, respectively. Furthermore, a comparison among results of the MK and I?T showed that the I?T method examined the unseen trend that cannot be detected by the MK technique at the Naula watershed. The pattern of trend detected on annual, seasonal, and monthly time-scales by three non-parametric approaches can help the water resources management authorities and hydrologists to comprehend the hazard and vulnerability under climate-change scenario over the study catchment area. � 2020 Faculty of Engineering, Alexandria University Final 2023-05-29T08:09:46Z 2023-05-29T08:09:46Z 2020 Article 10.1016/j.aej.2020.04.006 2-s2.0-85085940183 https://www.scopus.com/inward/record.uri?eid=2-s2.0-85085940183&doi=10.1016%2fj.aej.2020.04.006&partnerID=40&md5=663a71c717dc9c5baebdcd16e564d1ce https://irepository.uniten.edu.my/handle/123456789/25467 59 3 1595 1606 All Open Access, Gold Elsevier B.V.
