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 ...
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 ...
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 ...
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 ...
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 ...
Contribution of climatic variability and human activities to stream flow changes in the Haraz River basin, Northern Iran
(Journal of Hydro-environment Research, 2019-06)
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 ...
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 ...
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 ...
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). ...
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 ...
