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 ... -
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 ... -
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 ... -
Prediction, management and control of odour from landfill sites.
(2002)Due to the spread of urbanisation and increased environmental awareness, odour has become a major problem in communities surrounding landfills. The aim of this research was to investigate odour emissions from landfills ... -
Experimental cadmium contamination of the echinoid Stomopneustes variolaris (Echinodermata: Echinoidea) : influence of dosage and distribution of the metal in the organism.
(2002)Cd levels were measured in three different body compartments of the echinoid Stomopneustes variolaris after exposure to concentrations of 5 ug 1l, 20 ug 1l and 50 ug 1l Cd for a period of two weeks. The body compartments ... -
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 ... -
Estimating pedestrian accident risk using conflict techniques and digital imaging.
(2003)Accidents are a complex process involving many contributory factors. The understanding of the accident process has often been sought by the use of accident data. Although accident data provide a direct relationship to ... -
An investigation into the technical feasibility of using vegetated submerged bed constructed wetlands for the treatment of landfill leachate.
(2003)Landfill leachate treatment in South Africa is still in its early stages; research has been conducted but primarily at pilot scale level. Current legislation in South Africa does not prohibit the discharge of landfill ... -
Modelling flood inundation in the Mlazi river under uncertainty.
(2003)The research project described in this dissertation studies the modelling techniques employed for the Mlazi River in the context of flood analysis and flood forecasting in order to model flood inundation. These techniques ... -
Coastal water quality.
(2003)This research focuses on the pathogenic pollution of coastal recreational waters. Pollution of this resource can have serious social and economic implications. The health of the public could be compromised and there may ... -
A universal method for assessing intrinsic expansiveness of soils.
(2004)Many of the attempts made over the past six decades to find a universal system for assessing expansiveness of soils using soil index data have failed to follow the basic principles of soil mechanics. By overcoming most ... -
A sustainable delivery approach for peri-urban and rural areas.
(2004)Challenges of implementing Integrated Development programmes can be seen in the difficulty in aligning different departmental budgets and processes in the implementation phase of projects. This has had many implications ...
