The advancement of the waste resource optimization and scenario evaluation model: the inclusion of socio-economic and instituitonal indicator.
(2018)This study explored Novice Teacher Educators (NTEs) experiences of Relational Learning in a private Higher Education Institution (HEI) in South Africa. The main purpose of this study was to gain a deeper understanding ... -
Anaerobic digestion of energy crop (cassava)
(2019)Global energy demand is on the rise due to continuous increases in population, economic growth, and energy usage. Methane production through anaerobic digestion of organic materials provides a resourceful carrier of ... -
The analysis of connected back to back mechanically stabilised earth walls.
(2019)Back to back mechanically stabilised earth walls (MSEW’s) are designed independently as there is a lack of design guidance in the British Standard - Code of practice for strengthened/reinforced soils and other fills ... -
Analysis of the water distribution main replacement conundrum in Durban.
(2012)The optimisation of the decision of when to replace water distribution mains is a complex task. There are numerous drivers in the decision making process (informed by financial data, performance data and water quality ... -
An analysis on optimizing the use of sustainable urban drainage systems to provide non-potable water supply in the Isipingo region.
(2019)Population growth and urbanisation lead to increased water demand and stress on water resources. The increased demand implies an increased water treatment cost, utilities therefore charge higher tariffs consequently reducing ... -
Anthropogenic impacts and biophysical interactions in Lake St Lucia.
(2013)The St Lucia estuarine lake system in South Africa is part of a UN- ESCO World Heritage site and a Ramsar wetland of international importance. Like many estuarine systems worldwide St Lucia has experienced signi cant ... -
The applicability of C&D waste material in South Africa road construction.
(2015)In contrast to developed countries, South Africa is starting to adopt the practice of using recycled rubble from civil engineering demolition works in road construction. This change is due to environmental considerations, ... -
Application of a quantitative precipitation estimation algorithm for the s-band radar at Irene, South Africa.
(2014)Flash floods are the number one cause of death and damage with regard to natural disasters in South Africa (Poolman, 2009). Thus, the South African Weather Service (SAWS) and the National Disaster Management Centre (NDMC) ... -
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" ... -
The application of pole mounted amorphous core transformers to the electrical distribution network.
(2017)With the drive to save money when supplying electricity to customers, utilities are looking for solutions to decrease losses on distribution lines while maintaining good quality of supply. Amorphous core transformers are ... -
An assessment of carbon emissions reduction potential through zero waste activities in South African municipalities.
(2010)The inception of global warming has resulted in mitigation efforts across all relevant sectors. Waste management activities produce approximately 12% of methane emissions in South Africa. The current scope of waste ... -
Assessment of permeable reactive barriers alternative media for the remediation of nitrate-contaminated ground-waters.
(2013)The increase in the contamination of ground-water (GW) with nitrates in both developing and developed countries mainly results from agricultural activities and improper sanitation systems, and is a recent phenomenon that ... -
An assessment of radar, gauge and kriged gauge rainfall data in Free State, South Africa.
(2019)In the last decades, flooding has caused significant damages and death in South Africa. Flooding is associated with heavy rainfall events which vary largely in space and time. The forecast of such phenomena requires quality ... -
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 ...
