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 ... -
Anthropogenic impacts and biophysical interactions in Lake St Lucia.
(2013)The St Lucia estuarine lake system in South Africa is part of a UN- ESCO World Heritage site and a Ramsar wetland of international importance. Like many estuarine systems worldwide St Lucia has experienced signi cant ... -
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, ... -
Capacity of vertically loaded piles in low density sands.
(2011-05-26)The reduction of pile capacity associated with volume contraction of the soil close to the pile surface has been reported in carbonate deposits offshore North West Australia and in residual deposits of Southern ... -
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 ... -
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 ... -
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 ... -
Development of an integrated model for urban sustainable resilience through smart city projects in the Southern African context.
(2021)The construct Smart City has gone through a few phases in the last decades. Today there is still no consensus on an accurate definition of Smart City, even though a few concepts are now accepted by most stakeholders, ... -
Development of sounding equipment for the assessment of the time- settlement characteristics of recent alluvial deposits when subjected to embankment loads.
(1992)The whole of this thesis is my work unless specifically indicated to the contrary in the text, and has not been submitted in part or in whole to any other University. Some thirty years ago the author operated a deep ... -
Development of sounding equipment for the assessment of the time- settlement characteristics of recent alluvial deposits when subjected to embankment loads.
(1992)Many embankments on the soft, highly variable, recent alluvial deposits along the South African coast have suffered large settlements necessitating ongoing costly repairs. Due to the soft variable soils, borehole sampling ... -
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 ... -
Effective HIV and AIDS management : a South African construction sector model.
(2013)Abstract available on PDF file. -
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 ... -
High resolution space-time modelling of rainfall : the string of beads model.
(2003)The purpose of this study was to develop a rainfall model, continuous in space-time, which captures both the spatial and temporal structure of rainfall over a range of scales varying from lkm to 128km pixels at temporal ... -
The impact of the affirmative procurement policy on affirmable business enterprises in the South African construction industry.
(2000)The construction industry in South Africa is envisaged to play a pivotal role in the reconstruction of the South African economy, via the delivery of economic and social infrastructure. The skewed ownership I patterns ... -
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 ... -
Influence of rainfall on red-light running at signalised intersections and the service quality implications.
(2021)When drivers approach a signalised intersection stop-line, they must decide whether to stop or proceed and clear the intersection before the end of a green phase. The driver behaviour at the intersection affects signalised ... -
An investigation into the emissions of greenhouse gases associated with the disposal of solid waste in the eThekwini Municipality.
(2013)The amount of greenhouse gases (GHG) emitted due to waste management in the cities of developing countries is predicted to rise considerably in the near future; however, these countries have a series of problems in accounting ...
