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 ... -
Traffic circles in South Africa : traffic performance and driver behaviour.
(1997)This thesis presents the results of an investigation into traffic operations and driver behaviour at traffic circles under South African conditions. The scarcity of local traffic circles necessitated the development of ... -
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 ... -
Urban poverty reduction through municipal solid waste management (MSWM) : a case study of Maseru and Maputsoe in Lesotho.
(2002)The study was designed to generate data and information necessary for designing an appropriate sustainable solid waste management system, and examining the socio-economic benefits of urban municipal so lid waste management ... -
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 ... -
A study on sustainable waste disposal in South Africa using mechanical biological waste treatment.
(2009)The landfilling of Municipal Solid Waste poses a threat to the environment in the form of landfill emissions. These emissions are a result of the biochemical breakdown of the waste in the anaerobic landfill environment. A ... -
Towards a zero waste South Africa : a case study on post-consumer solid waste management in rural and urban areas.
(2009)Through the National Environmental Management Act (No. 107 of 1998), the South African Department of Environmental Affairs and Tourism (DEAT) introduced the concept of the Waste Hierarchy (Reduce - Reuse - Recover - Dispose) ... -
The role of waste data in changing behaviour : the case of the South African waste information system (SAWIS)
(2011)The South African waste information system (SAWIS) developed and implemented by the Department of Environmental Affairs in 2006, provided a unique case study to explore the research question “Can the collection of data ... -
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 ... -
A new approach to the polyaxial stress numerical analysis of underground openings.
(2012)The traditional design methodologies for tunnel and underground excavations are divided in to three categories: Empirical, Analytical, and Observational approaches, whereas in the last years the Numerical approach has ... -
Predicting shoreline response to wave and sea level trends.
(2012)In March 2007 the KwaZulu-Natal coastline was devastated by an extreme storm event. There is international concern that such events are associated with climate change. There is evidence of global changes in climate but ... -

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 use of commercial garden refuse at different degrees of maturity as an organic carbon source to bio-denitrify treated MSW landfill leachate.
(2014)Abstract available in PDF file. -
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 ... -
Maximising the photobiological production of hydrogen using leachate, while monitoring algal photosynthesis using pam fluorometry.
(2014)Hydrogen is universally known as the most efficient renewable energy source capable of meeting global energy demands. Chlamydomonas reinhardtii has the ability to produce biohydrogen during the metabolic engineering of ...
