Application of revised innovative trend analysis in lower Drava River

Abstract Changes in the streamflow pattern raise a plethora of implications on morphological, economic, social, and cultural aspects an entire river basin. Trend analysis hydrological time series is most common method to identify these changes. Several methods have been proposed trends series. In present study, Mann–Kendall (MK), innovative trend (ITA), revised (RITA) were used discharge sediment load at two gauging sites lower Drava River Basin, during 1988–2017 with objective compare understand limitations methods. Innovative provided greater visualization different magnitude discharges as compared test. However, it was observed that due certain assumptions, ITA produced significant when insignificant. The significance obtained from RITA close agreement this regard, determining needs be rechecked revised.
