The breaching of temporary open/closed estuaries.
(2007)Intermittent breaching of sand barriers at temporary open estuaries plays a key role in the functioning of these systems. Breaching events lead to large and rapid changes in the physico-chemical environment which in turn ... -
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 ... -
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 ... -
The characterization of stormwater runoff from road surfaces.
(2006)The water quality of stormwater runoff from various road surfaces in Durban, KwaZulu- Natal was characterised by monitoring programmes established at four study areas. The investigation focussed on obtaining representative ... -
Circular economy design visioning: exploring industrial and urban symbiosis in South African cities.
(2017)Cities of tomorrow will be at the coalface of the complex challenges posed by climate change, e.g. resource scarcity. Climate change adaptation strategies will include circular economy (CE) practices (e.g. industrial and ... -
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 ... -
Coastline impacts of tropical cyclones and climate change on Mauritius.
(2014)The tourism industry has grown to become the third pillar of the Mauritian economy, due mainly to its prestigious beaches. However, Mauritius is prone to severe tropical cyclones which can have detrimental impacts on its ... -
A comparative life cycle assessment (LCA) of water treatment plants using alternative sources of water (seawater and mine affected water).
(2016)Water is a replenishing, yet at times scarce resource that is necessary for the growth and development of all organisms and plant life. In South Africa, the situation is challenging due to competing demands for limited ... -
A comparison of the design approach recommended in the South African national standard for a reinforced soil wall with a finite element design to identify an opportunity to optimise the design.
(2019)Reinforced soil structures are used extensively for retaining wall applications in South Africa, with the design methodology recommended within the civil engineering fraternity as specified in the design code SANS 8006-1:2018, ... -
Conditioning Tropical Rainfall Measuring Mission (TRMM) data using ground based rainfall data.
(2016)Rainfall helps to structure society in a geographical sense, thus correct capturing of rainfall data and recording is very importantant in ensuring that water resources planners have information that can be used to make ... -
Core entrepreneurial competencies for civil engineers to be successful entrepreneurs.
(2017)Purpose: Since entrepreneurship is viewed as a path to sustainable economic development, this study examined the managerial and entrepreneurial competencies necessary for entrepreneurial action. Design/methodology/approach: ... -
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 ... -
Critique of durability specifications for concrete bridges on national roads in South Africa.
(2011-05-06)Damage to reinforced concrete bridges due to carbonation and chloride induced corrosion is widespread in South Africa and prone in environments where carbon dioxide is at high levels as well as in marine environments where ... -
Denitrification of high strength landfill leachate using garden refuse compost and pine bark.
(2009)Landfill leachate, a toxic by-product formed through the decomposition of organic matter, is harmful to the environment and human health. After nitrification, the concentration of nitrate in discharged leachate may still ... -
Denitrification of high strength nitrified landfill leachate using raw and lightly composted commercial garden refuse (CGR) as carbon sources.
(2011)Waste is commonly disposed in landfills, this result in the formation of leachate which needs to be treated to acceptable standards before being discharged to the environment. High concentrations of pollutants, particularly ... -
Denitrification of leachate using domestic waste at different levels of stability : simulations in batch test.
(2011)Disposing of waste on land has been a method practiced by many countries because it is relatively inexpensive. This has led to the fast increase of landfilling option which is also due to increase of waste generation, ... -
Development of ‘green’ rigid pavements incorporating recyclable rubber and paper mill products.
(2019)Natural aggregate resources used as conventional fillers in concrete production are constantly diminishing. Several studies have suggested that there will be a lot of pollution in the degradation of waste rubber products. ... -
The development of a latent heat thermal energy storage system using a phase change material for solar energy application.
(2010)This investigation forms part of an attempt to provide an alternative to conventional power generation technologies that use fossil fuels which have impact on global warming. The field of this investigation covers the ...
