Coastline impacts of tropical cyclones and climate change on Mauritius.
(2014)The tourism industry has grown to become the third pillar of the Mauritian economy, due mainly to its prestigious beaches. However, Mauritius is prone to severe tropical cyclones which can have detrimental impacts on its ... -
A comparative life cycle assessment (LCA) of water treatment plants using alternative sources of water (seawater and mine affected water).
(2016)Water is a replenishing, yet at times scarce resource that is necessary for the growth and development of all organisms and plant life. In South Africa, the situation is challenging due to competing demands for limited ... -
A comparison of the design approach recommended in the South African national standard for a reinforced soil wall with a finite element design to identify an opportunity to optimise the design.
(2019)Reinforced soil structures are used extensively for retaining wall applications in South Africa, with the design methodology recommended within the civil engineering fraternity as specified in the design code SANS 8006-1:2018, ... -
Conditioning Tropical Rainfall Measuring Mission (TRMM) data using ground based rainfall data.
(2016)Rainfall helps to structure society in a geographical sense, thus correct capturing of rainfall data and recording is very importantant in ensuring that water resources planners have information that can be used to make ... -
Core entrepreneurial competencies for civil engineers to be successful entrepreneurs.
(2017)Purpose: Since entrepreneurship is viewed as a path to sustainable economic development, this study examined the managerial and entrepreneurial competencies necessary for entrepreneurial action. Design/methodology/approach: ... -
Costing calculation of operation and maintenance in community water supplies.
(2001)Studies of community water have been on the increase since the International Drinking Water Supply and Sanitation Decade, 1981 - 1990. However there is some key areas of community water supply that still require research ... -
Critique of durability specifications for concrete bridges on national roads in South Africa.
(2011-05-06)Damage to reinforced concrete bridges due to carbonation and chloride induced corrosion is widespread in South Africa and prone in environments where carbon dioxide is at high levels as well as in marine environments where ... -
Denitrification of high strength landfill leachate using garden refuse compost and pine bark.
(2009)Landfill leachate, a toxic by-product formed through the decomposition of organic matter, is harmful to the environment and human health. After nitrification, the concentration of nitrate in discharged leachate may still ... -
Denitrification of high strength nitrified landfill leachate using raw and lightly composted commercial garden refuse (CGR) as carbon sources.
(2011)Waste is commonly disposed in landfills, this result in the formation of leachate which needs to be treated to acceptable standards before being discharged to the environment. High concentrations of pollutants, particularly ... -
Denitrification of leachate using domestic waste at different levels of stability : simulations in batch test.
(2011)Disposing of waste on land has been a method practiced by many countries because it is relatively inexpensive. This has led to the fast increase of landfilling option which is also due to increase of waste generation, ... -
Development of ‘green’ rigid pavements incorporating recyclable rubber and paper mill products.
(2019)Natural aggregate resources used as conventional fillers in concrete production are constantly diminishing. Several studies have suggested that there will be a lot of pollution in the degradation of waste rubber products. ... -
The development of a latent heat thermal energy storage system using a phase change material for solar energy application.
(2010)This investigation forms part of an attempt to provide an alternative to conventional power generation technologies that use fossil fuels which have impact on global warming. The field of this investigation covers the ... -
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 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 ... -
An economic comparison of the waste management schemes employed in Cape Town and Johannesburg.
(2006)The disposal of waste into landfill sites is currently the most commonly employed method of dealing with waste in South Africa as well as internationally. However the global trend towards operating waste management systems ... -
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 ...
