Does training improve sanitary inspection answer agreement between inspectors? Quantitative evidence from the Mukono district, Uganda
(MDPI, 2020-10-10)Sanitary inspections (SIs) are checklists of questions used for achieving/maintaining the safety of drinking-water supplies by identifying observable actual and potential sources and pathways of contamination. Despite the ... -
Dynamically dimensioned search embedded with piecewise opposition-based learning for global optimization
(2019-05-26)Dynamically dimensioned search (DDS) is a well-known optimization algorithm in the field of single solution-based heuristic global search algorithms. Its successful application in the calibration of watershed environmental ... -
Field-based methods for measuring greenhouse gases emissions from on-site sanitation systems: A systematic review of published literature
(Heliyon, 2023-04)On-site sanitation systems (OSS) are a source of greenhouse gas (GHG) emissions. Although ef- forts have been made recently to measure and quantify emissions from septic tanks using various field-based methods, the vast ... -
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 ... -
Hydrodynamic modelling of floods and estimating socio‑economic impacts of floods in Ugandan River Malaba sub‑catchment
(Earth Systems and Environment : Springer link, 2022-01-01)River Malaba sub-catchment tends to experience dramatic flooding events, with several socio-economic impacts to the nearby communities, such as loss of lives and destructions of physical infrastructure. Analysis of ... -
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 ... -
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 ... -
Impacts of climate variability and changing land use/land cover on River Mpanga flows in Uganda, East Africa
(Environmental Challenges : Elsevier, 2021-12-09)We analyzed River Mpanga Catchment (RMC) land use/land cover (LULC) types based on Landsat images for 2000, 2008 and 2014. Soil and Water Assessment Tool (SWAT) was driven by daily meteorological data from 2000 to 2011 to ... -
Interpretation of constant suction direct shear test
(EDP Sciences, 2023)Constant suction direct shear test enables the understanding of the failure mechanism in rainfall- induced landslides. It can be conducted using a conventional direct shear apparatus with some modifications. The constant ... -
Investigating false start of the main growing season: a case of Uganda in East Africa
(Heliyon, 2021-11-19)False start of the growing season (Fsos) is a component of the onset variability related to agronomic drought that adversely impact on agricultural production and productivity. In the sub-Saharan Africa (SSA) where agriculture ... -
Long-term climatic water availability trends and variability across the African continent
(Theoretical and Applied Climatology : Springer Link, 2021-06-29)This study analyzed trends and variability in climatic water availability (CWA) across the African continent using monthly precipitation and potential evapotranspiration (PET) over the period 1901–2015. Climatic water ... -
Modelling chlorine residuals in drinking water: a review
(International Journal of Environmental Science and Technology, 2022-01-24)World Health Organization’s guidelines on water quality limit concentrations of residual chlorine in drinking water to the range 0.2–5 mg/l. Modelling tends to be applied to understand how chlorine concentrations can be ... -
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 ... -
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 ... -
Osmotic consolidation of expansive soil
(Japanese Geotechnical Society Special Publication, 2019)The mechanical behavior of expansive soils is influenced by the concentration of salts in their pore water. Research has shown that volume change of soil can occur due to a difference in salt concentration in the pore ... -
