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 ... -
Effective HIV and AIDS management : a South African construction sector model.
(2013)Abstract available on PDF file. -
The efficacy of silver/copper nanoparticles in biofilm control on water supply pipeline materials.
(2019)Biofilms are microorganisms that inhabit inside a matrix made mainly of exopolysaccharides that are secreted from the micriobual consortia. Silver and copper ions efficacies have been proven in vitro, but, Huang, et al., ... -
The efficacy of using the microalgae chlorella sp. for the treatment of hazardous landfill leachate.
(2015)Abstract available in PDF file. -
Environmental impacts of the construction phase of an intensive development project on a coastal forest wetland : case study : Seaward Estates, Ballito.
(2011-01-14)Storm water runoff is a leading cause of degradation in the water quality of receiving water bodies. Although legislation requires that Environmental Impact Assessments (EIA) are performed and Environmental Management ... -
Environmental management strategy : Krantzkloof Nature Reserve, a case study.
(2006)KZN Nature Conservation Services budgetary cuts for the KrantzkloofNature Reserve (KNR) has led to economic shortfalls in important areas like facilities maintenance and invader plant control. The study has found that the ... -
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 ... -
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 ... -
Evaluation of PCI reverse osmosis membrane on landfill leachate.
(2010-10-20)The specific objective of this study was to evaluate a PCI reverse osmosis membrane for -
Evaluation of using local information from donor catchments to improve performance of selected deterministic and empirical design flood estimation methods in South Africa.
(2021)There are a number of design flood estimation methods routinely used in South Africa. Flood Frequency Analysis (FFA) remains the preferred technique in instances where adequate records of observed data are available. ... -
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 ... -
Effect of coral reefs on wave attenuation and erosion: Mnemba Island, Zanzibar.
(2017)Global warming and sea level rise are some of the greatest threats humanity faces today with low-lying coral reef islands most vulnerable to these threats and their repercussions. This study focuses on the mechanisms that ... -
Finite element analysis on the behaviour of multi-storey steel frame with concrete slabs against progressive collapse under fire conditions.
(2020)This research was conducted to study the behaviour of a multi-storey steel frame with concrete slabs against progressive collapse under fire conditions. An implicit coupled thermomechanical analysis was executed using a ... -
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 ...
