An investigation into the reduction of greenhouse gases associated with the disposal of municipal solid waste for the development of an institutional framework in developing countries.
(2015)Municipal solid waste in landfills releases the greenhouse gas (GHG), methane. This study aimed to develop an institutional framework that could assist municipalities in developing countries to adopt an integrated waste ... -
The applicability of C&D waste material in South Africa road construction.
(2015)In contrast to developed countries, South Africa is starting to adopt the practice of using recycled rubble from civil engineering demolition works in road construction. This change is due to environmental considerations, ... -
On weather and waves : applications to coastal engineering.
(2015)Shoreline erosion in response to extreme wave events can be severe. The reduction in beach width leaves development within the hinterland exposed and vulnerable to future wave attack. Wave climates are a fundamental ... -
Circular economy design visioning: exploring industrial and urban symbiosis in South African cities.
(2017)Cities of tomorrow will be at the coalface of the complex challenges posed by climate change, e.g. resource scarcity. Climate change adaptation strategies will include circular economy (CE) practices (e.g. industrial and ... -
Flood estimation in developing countries with case studies in Ethiopia.
(2017)Extreme flood events have become more destructive in some parts of Ethiopia. Thus, accurate estimates of flood frequencies are vital for effective flood risk management. Yet, estimation of the peak flood is exceptionally ... -
Influence of rainfall on quality of service at multilane roundabouts and its time headway implications.
(2018)Roundabouts, or traffic circles as they are often called in South Africa, are priority intersections with a unique yield rule. Drivers approaching the roundabout must give way to those that are already circulating the ... -
A mathematical model development for simulating in-stream processes of non-point source pollutants.
(2018)In coming years, chronic water stress is inevitable owing to the unavailability of fresh water. This situation is occasioned by rapid urbanisation, climate change, rising food demand, and production. The increasing rate ... -
The applicability of C&D waste material in South Africa road construction.
(2018)In contrast to developed countries, South Africa is starting to adopt the practice of using recycled rubble from civil engineering demolition works in road construction. This change is due to environmental considerations, ... -
Development of a mathematical model considering nutrients kinetics for assessing uMgeni river water quality.
(2018)Surface water is an essential component of the natural environment which needs to be sheltered from all sources of contamination because human and aquatic animals depend on it for their survival. However, the discharge of ... -
Anaerobic digestion of energy crop (cassava)
(2019)Global energy demand is on the rise due to continuous increases in population, economic growth, and energy usage. Methane production through anaerobic digestion of organic materials provides a resourceful carrier of ... -
Effect of rainfall on function service quality deterioration of dark roadways and its implication for stopping sight distance.
(2019)Driving in the rain at night is challenging and more so if the roadway has no light. This study aims to ascertain whether rainy dark roadways would have significant influence on functional service quality reduction, and ... -
Development of a sustainable evolutionary-inspired artificial intelligent system for municipal water demand modelling.
(2020)This study presents the development of a differential evolution (DE)-inspired artificial neural network (ANN) that incorporates climate and socioeconomic information for a more accurate and reliable water ... -
Development of a universal water quality index and water quality variability model for South African river catchments.
(2020)The assessment of water quality has turned to be an ultimate goal for most water resource and environmental stakeholders, with ever-increasing global consideration. Against this background, various tools and water quality ...
