    Hydrological Model Supported by a Step-Wise Calibration against Sub-Flows and Validation of Extreme Flow Events 

    Onyutha, Charles (Water, 2019)
    Most hydrological models have fixed structures and their calibrations are typified by a conventional approach in which the overall water balance closure is considered (without a step-wise focus on sub-flows’ variation). ...

    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 ...

    Spatial and temporal variability of rainfall in the Nile Basin 

    Onyutha, C.; Willems, P. (Hydrology and Earth System Sciences, 2015)
    Spatiotemporal variability in annual and seasonal rainfall totals were assessed at 37 locations of the Nile Basin in Africa using quantile perturbation method (QPM). To get insight into the spatial difference in rainfall ...

    Empirical statistical characterization and regionalization of amplitude–duration–frequency curves for extreme peak flows in the Lake Victoria Basin, East Africa 

    Onyutha, Charles; Willems, Patrick (Hydrological Sciences Journal, 2015)
    This paper focuses on a regionalization attempt to partly solve data limitation problems in statistical analysis of high flows to derive discharge–duration–frequency (QDF) relationships. The analysis is based on 24 selected ...

    Identifying indigenous practices for cultivation of wild saprophytic mushrooms: responding to the need for sustainable utilization of natural resources 

    Wendiro, Deborah; Wacoo, Alex Paul; Wise, Graham (Journal of Ethnobiology and Ethnomedicine, 2019)
    Due to increasing pressure on natural resources, subsistence agriculture communities in Uganda and Sub-Saharan Africa are experiencing increasingly restricted access to diminishing natural resources that are a ...

    Variability of seasonal and annual rainfall in the River Nile riparian countries and possible linkages to ocean–atmosphere interactions 

    Onyutha, Charles (Hydrology Research, 2016)
    Variability analyses for the rainfall over the Nile Basin have been confined mostly to sub-basins and the annual mean of the hydroclimatic variable based on observed short-term data from a few meteorological stations. ...

    Geospatial Trends and Decadal Anomalies in Extreme Rainfall over Uganda, East Africa 

    Onyutha, Charles (Onyutha, C. (2016). Geospatial trends and decadal anomalies in extreme rainfall over Uganda, East Africa. Advances in Meteorology, 2016. http://dx.doi.org/10.1155/2016/6935912, 2016)
    Trends and variability in series comprising the mean of fifteen highest daily rainfall intensities in each year were analyzed considering entire Uganda.The data were extracted from high-resolution (0.5∘ × 0.5∘) gridded ...

    Phosphate removal from aqueous solution using iron oxides: adsorption, desorption and regeneration characteristics 

    Ajmal, Zeeshan; Muhmood, Atif; Usman, Muhammad; Kizito, Simon; Lu, Jiaxin; Dong, Renjie; Wu, Shubiao (Journal of Colloid and Interface Science, 2018)
    Dynamics of phosphate (PO4 3-) adsorption, desorption and regeneration characteristics of three lab-synthesized iron oxides, ferrihydrite (F), goethite (G), and magnetite (M) were evaluated in this study. Batch experiments ...

    Comparison of different statistical downscaling methods for climate change rainfall projections over the Lake Victoria basin considering CMIP3 and CMIP5 

    Onyutha, C.; Tabari, H.; Rutkowska, A.; Nyeko-Ogiramoi, P.; Willems, P. (Journal of Hydro-environment Research, 2016)
    In this study, outputs of three statistical downscaling (SD) methods including the change factor (Delta), simplified (simQP) and advanced (wetQP) quantile-perturbation-based approaches were compared based on daily rainfall ...

    Uncertainties in Flow-Duration-Frequency Relationships of High and Low Flow Extremes in Lake Victoria Basin 

    Onyutha, Charles; Willems, Patrick (Water, 2013)
    This paper focuses on uncertainty analysis to aid decision making in applications of statistically modeled flow-duration-frequency (FDF) relationships of both daily high and low flows. The analysis is based on 24 selected ...
