    Decadal Analysis of River Flow Extremes Using Quantile-Based Approaches 

    Tabari, Hossein; Teferi Taye, Meron; Onyutha, Charles; Willems, Patrick (er Resources Management, 2017)
    Next to the traditional analysis of trends in time series of hydro-climatological variables, analysis of decadal oscillations in these variables is of particular importance for the risk assessment of hydro-climatological ...

    Identification of sub-trends from hydro-meteorological series 

    Onyutha, Charles (Stochastic environmental research and risk assessment, 2016)
    In hydro-meteorological trend analysis, an alteration in the given variable is detected by considering the long-term series as a whole. Whereas the long-term trend may be absent, the significance of hidden (short-dura ...

    Analyses of rainfall trends in the Nile River Basin 

    Onyutha, Charles; Tabari, Hossein; Taye, Meron T.; Nyandwaro, Gilbert N.; Willems, Patrick (Journal of hydro-environment research, 2016)
    Trends in rainfall at 39 locations of the Nile River Basin (NRB) in Africa were analyzed. Comparison was made between rainfall trend results from the long-term data and those of short-term series selected over different ...

    On Rigorous Drought Assessment Using Daily Time Scale: Non-Stationary Frequency Analyses, Revisited Concepts, and a New Method to Yield Non-Parametric Indices 

    Onyutha, Charles (Hydrology, 2017)
    Some of the problems in drought assessments are that: analyses tend to focus on coarse temporal scales, many of the methods yield skewed indices, a few terminologies are ambiguously used, and analyses comprise an implicit ...

    Statistical Uncertainty in Hydrometeorological Trend Analyses 

    Onyutha, Charles (Advances in Meteorology, 2016)
    This study demonstrates the existence of uncertainty in hydrometeorological trend analyses using historical rainfall from Kenya in East Africa. With respect to the influence of short- and long-term persistence on trend ...

    Analyses of rainfall extremes in East Africa based on observations from rain gauges and climate change simulations by CORDEX RCMs 

    Onyutha, Charles (Climate Dynamics, 2020)
    This study derived twelve Extreme Rainfall Indices (ERIs) such as the Maximum Dry Spell (MDS) and Maximum Wet Spell (MWS) from daily rainfall observed over the period 1961–1990 at nine locations across East Africa. Capacity ...

    Contribution of climatic variability and human activities to stream flow changes in the Haraz River basin, northern Iran 

    Pirniaa, Abdollah; Choubin, Bahram; Omidvar, Ebrahim; Onyutha, Charles; Torabi Haghighi, Ali (Journal of Hydro-Environment Research, 2019)
    In northern Iran’s Haraz River basin between 1975 and 2010, hydrological sensitivity, double mass curve, and Soil and Water Assessment Tool (SWAT) methods were applied to monitoring and analysing changes in stream flow ...
