A hydrological model skill score and revised R-squared
(Hydrology Research, 2022-01-01)Despite the advances in methods of statistical and mathematical modeling, there is considerable lack of focus on improving how to judge models’quality. Coefficient of determination (R2) is arguably the most widely applied ... -
Graphical-statistical method to explore variability of hydrological time series
(Hydrology Research, 2021-02)Due to increasing concern on developing measures for predictive adaptation to climate change impacts on hydrology, several studies have tended to be conducted on trends in climatic data. Conventionally, trend analysis ... -
Quality of packaged drinking water along its production and distribution chain: a case of central and eastern Uganda
(Kyambogo University (un published work), 2019-10)Access to safe and affordable drinking water is one of core targets under Sustainable Development Goals: 6. Bottled water is a path way for such safe access as from 1990, with currently more than 40 registered brands amidst ... -
Negative emotions about climate change are related to insomnia symptoms and mental health: cross-sectional evidence from 25 countries
(Current Psychology : Springer, 2021-02-16)Climate change threatens mental health via increasing exposure to the social and economic disruptions created by extreme weather and large-scale climatic events, as well as through the anxiety associated with recognising ... -
Application of value analysis concept on construction cost of low volume roads in Uganda
(Kyambogo University (un published work), 2019-11)The success of implementation of highway infrastructure projects is usually measured against three parameters; quality, time and cost. However, some of these projects do not achieve expected project goals in terms of ... -
Combined use of graphical and statistical approaches for analyzing historical precipitation changes in the black sea region of Turkey
(MDPI: Water, 2020-03-05)Many statistical methods have been developed and used over time to analyze historical changes in hydrological time series, given the socioeconomic consequences of the changes in the water cycle components. The classical ... -
Analyses of precipitation and evapotranspiration changes across the lake Kyoga basin in East Africa
(MDPI: Water, 2020-04-16)This study analyzed changes in CenTrends gridded precipitation (1961–2015) and Potential Evapotranspiration (PET; 1961–2008) across the Lake Kyoga Basin (LKB). PET was computed from gridded temperature of the Princeton ... -
African food insecurity in a changing climate: the roles of science and policy
(Wiley Online Library: Food and Energy Security, 2018-12-12)African population is projected to double to 2.48 billion people by 2050. The population increase poses a serious challenge of increasing food supply to meet the future demand. This challenge is compounded by climate change ... -
Impact of design flaws on cost overruns in road Construction projects in Uganda
(Kyambogo University (un published work), 2019-11)The inability to complete projects within time and budget continues to be a chronic problem worldwide and it is worsening. Cost overruns have therefore remained a major setback in implementation of road construction ... -
Hydrological model supported by a step-wise calibration against sub-flows and validation of extreme flow events
(MDPI, 2019-01-31)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). ... -
Impact of addition of banana fibres at varying fibre length and content on mechanical and microstructural properties of concrete
(Hindawi: Advances in Civil Engineering, 2021-10-08)'is experimental study aimed at investigating the impact of addition of banana fibres on the mechanical (compression, splitting tension, and flexure) and microstructural (microscopic morphology and Energy Dispersive X-ray ... -
Influence of urbanization on performance of public utilities: a case of national water and sewerage corporation in lira municipality, Uganda
(Kyambogo University (un published work), 2018-11)The study sought to investigate the influence of urbanization on the pe1formance of NWSC in LMC with objectives to establish the relationship between urbanization and performance, to establish the challenges faced by ... -
Occupational safety training and practices in selected vocational training institutions and workplaces in Kampala, Uganda
(Taylor&Francis: International Journal of Occupational Safety and Ergonomics, 2015-12-23)Several industrial accidents, some of them fatal, have been reported in Uganda. Causes could include training gaps in vocational training institutions (VTIs) and workplaces. This study investigated how occupational safety ... -
Comparing performance of different lumped conceptual hydrological models : a case study of River Kafu catchment
(Kyambogo University [ Unpublished work], 2020-10)Planning for water resources management can be supported by hydrological modeling. In a typical data scarce region, the compatibility of structures of various models with the limited data can greatly affect results of ... -
