The flocculation dynamics of cohesive sediments in the St. Lucia and Mfolozi estuaries, South Africa.
(2011)Increasing turbidities due to land use changes and poor catchment management can cause negative impacts on estuaries worldwide. High turbidity has an impact on the biological functioning of estuaries which are amongst our ... -
Flood estimation for roads, bridges and dams.
(2010-10-20)Flood estimation can be classified into two categories, i.e. flood prediction and flood forecasting. Flood prediction is used for the estimation of design floods, which are floods associated with a degree of risk of being ... -
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 ... -
Flow patterns around groynes in the coastal zone.
(2013)Semi-permeable groynes are used to modulate the long-shore transport for beach management purposes, but the optimal design of these structures remains unresolved. This in part is due to their ability to behave as both a ... -
Following a cleaner production approach to guide the permitting process of odour producing industries : an assessment of case studies.
(2011)The eThekwini Municipality is facing two major challenges in controlling odorous emissions by various industries in the South Durban Basin; firstly, getting industry to manage their onsite odorous emissions and, secondly ... -
Further development of WROSE, decision-making tool for KZN municipalities.
(2016)Abstract available in PDF file. -
Garden refuse composting as part of an integrated zero waste strategy for South African municipalities.
(2010)Garden refuse has been seen to constitute a significant proportion of the total waste stream received at landfills in the eThekwini Municipal Area (EMA). With the growing demand for conserving “precious landfill airspace” ... -
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 ... -
Green roof retrofitting: a study into the structural implications associated with green roof retrofits.
(2017)The realities of climate change have fast become apparent. It is for this reason that vast quantities of research explored potential mitigation methods to alleviate the strain placed on the environment and the planet by ... -
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 ... -
Hydrodynamics of temporary open estuaries, with case studies of Mhlanga and Mdloti.
(2004)Estuaries are unique coastal bodies of water where water derived from land meets the sea. In order to preserve estuaries and minimise the effects of human interference in these sensitive areas, an understanding of the ... -
Identification, quantification and classification of risks pertaining to building contractors in the JBBCC (Principal Building Agreement)
(2010-09-06)Risks are present in every aspect of business. As one of the biggest industries worldwide, the construction industry is plagued with risks. Being such a large industry, there are hundreds of contracts signed every day. ... -
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 ... -
Implementation of green measures for sustainable low-income housing in developing countries : guidelines for the design of new settlements in the South African context.
(2014)In South Africa, about 15,3% of the households were living in 2011 in formal state-subsidised low-income houses (houses for households with income lower than R 3500 - about $ 350 - per month), whereas 12,1% were living ... -
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 the degree of waste pre-treatment on carbon emissions' production and nature.
(2007)This study was carried out to gain knowledge of the degradation processes in an anaerobic environment of pre-treated waste for different degrees of pre-treatment and the evolution of waste pre-treatment by forced aeration. ... -
An investigation into adopting different piling systems for integral abutment bridges.
(2016)In recent years the use of integral abutment bridges has become increasingly popular, globally. These bridges have many advantages because the super-structure and sub-structure are monolithic in nature, no bearings and ... -
Investigation into the denitrification of high strength landfill leachate using pine bark and raw and composted commercial garden refuse as a carbon source : column studies.
(2010)Landfill leachate, the liquid discharge from Municipal Solid Waste (MSW) landfills, is the combination of the surface runoff and ground water that percolates through the waste and the liquid contained in the waste itself ... -
An investigation into the effectiveness of systems thinking approach in illuminating understanding of poverty as a complex situation : a South African case study.
(2007)We are living in a world where academics and politicians seek to define the problem of poverty and where a range of policies and programmes have been introduced in response to one or other version of the problem. Over the ...
