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 ... -
Rural road maintenance through labour-based lengthmen system in Zambia.
(2000)Rural road maintenance has received little or no attention in Zambia for a long time, resulting in an adverse impact on the economy. Meanwhile Road Authorities have continued to use traditional capital-intensive periodic ... -
Gaseous and particulate emissions.
(2000)The need to limit sulphur dioxide, nitrous oxides and particulate matter emissions from fossil fuel combustion processes is now a major factor in the design, construction and operation of plants. Over the past 5 to 10 ... -
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 ... -
A numerical study of bacteria transport through porous media using the green element method.
(2000)The continued widespread contamination of the subsurface environment by microbial pathogens and chemical wastes has resulted in an increased interest in the factors that influence microbial transport through porous ... -
Ultimate load and deflection behaviour of cellular beams.
(2001)Cellular beams were developed in 1987 and are an adaptation of castellated beams having many of the same advantages and disadvantages. There are no published results of tests on cellular beams and there is only one ... -
Environmental study of the rehabilitation of the Monze-Zimba Road in Zambia.
(2001)It is very unfortunate that despite laws that require adequate incorporation and integration of environmental concerns at all phases of the economic developmental projects in Zambia, the research findings of this ... -
A linear catchment model for real time flood forecasting.
(2001)A linear reservoir cell model is presented which is proposed as a good candidate for real time flood forecasting applications. The model is designed to be computationally efficient since it should be able to run on ... -
Numerical and experimental study of transient heat transfer through concrete.
(2001)The increase in temperature of developing concrete as a result of heat liberated by cementing reactions is the primary cause for thermally induced cracks in large concrete elements. It is very essential, in engineering ... -
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 ... -
Monitoring the health of the rivers of the Durban Metropolitan Area using fresh water invertebrates. A pilot study.
(2002)This document is aimed at all parties involved with conservation, planning and management of rivers within the Greater Durban Metropolitan Area, South Africa. The intentions of this study were to provide information on ... -
Characterisation and management of landfill emissions under a sub- tropical climate using full-scale landfill cells.
(2002)It is now widely understood that landfills, compnslng municipal solid wastes, typically undergo biological degradation processes in what are referred to as Bio-Reactor Landfills. These microbiological processes cause the ... -
Application of digital imaging in measuring cross track drift of vessels entering a port.
(2002)Durban is the busiest container port in Africa and there are plans for significant expansion during the next few years. This expansion includes the widening of the port entrance channel to accommodate larger "post-panamax" ... -
Turbulent mixing and dispersion in environmental flows.
(2002)Stably stratified flows are common in the environment such as in the atmospheric· boundary layer, the oceans, lakes and estuaries. Understanding mixing and dispersion in these flows is of fundamental importance in ...
