Contributions of human activities and climatic variability to changes in river Rwizi flows in Uganda, East Africa
(MDPI, 2021-09)This study employed Soil and Water Assessment Tool (SWAT) to analyze the impacts of climate variability and human activities on River Rwizi flows. Changes in land use and land cover (LULC) types from 1997 to 2019 were ... -
COVIDiStress diverse dataset on psychological and behavioural outcomes one year into the COVID-19 pandemic
(Scientific data, 2022)During the onset of the COVID-19 pandemic, the COVIDiSTRESS Consortium launched an open-access global survey to understand and improve individuals’ experiences related to the crisis. a year later, we extended this line ... -
Dam breach analysis of Kibimba Dam in Uganda using HEC-RAS and HEC-GeoRAS
(Springer, 2023-10)Dam failures have severe consequences on human life and property. In the case of an earth filled Kibimba Dam located in Eastern Uganda, the occurrence of a food equal to or larger than the probable maximum food (PMF) ... -
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 ... -
Drought severity across Africa: a comparative analysis of multi-source precipitation datasets
(Springer, 2024-04)An accurate analysis of climate extremes is essential for impact assessment and devising appropriate adaptation measures. There is an urgent need to assess precipitation products in capturing the increasing occurrence of ... -
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 ... -
Improving household water treatment: using zeolite to remove lead, fluoride and arsenic following optimized turbidity reduction in slow sand filtration
(Sustainable Environment Research, 2024-03)Despite the United Nations 2030 agenda, large number of both urban and rural dwellers in low-income countries continue to lack access to improved water. Thus, increased effort is required towards enhancing low-cost ... -
Influence of physical and water quality parameters on residual chlorine decay in water distribution network
(Heliyon, 2024-05-07)Chlorine is the most common disinfectant in drinking water distribution practice. World Health Organization recommends 0.2–5.0 mg/l of residual chlorine in drinking water. This paper analyzed influence of physical and ... -
Interpretation of constant suction direct shear test
(EDP Sciences, 2023-04)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 equipment productivity in feeder road maintenance in Uganda
(Elsevier, 2023-01)Rural roads form the largest part of Uganda’s road network (approximately 50.2%) and is therefore a critical part of economic growth in an agriculturally dependent country like Uganda. With Uganda’s rural population standing ... -
