Life cycle assessment of municipal solid waste management in Newcastle Local Municipality.
(2014)Abstract available from the print copy. -
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 ... -
The lining of steep landfill slopes in South Africa and the applicability of the "minimum requirements for waste disposal by landfill" by the Department of Water Affairs and Forestry.
(2013)In August 2013, the landfill liner designs prescribed by the Minimum Requirements for Waste Disposal by Landfill was superseded by the containment barriers of landfills, now prescribed by the National Norms and Standards ... -
Long term emission from pre treated waste : column studies.
(2010-10-20)Emissions resulting from waste degradation processes have a high polluting potential -
Long term emissions from pretreated waste : lysimeter studies.
(2007)Landfill emissions are the major environmental impact associated with the landfilling of solid wastes. These emissions which are mainly gases and leachate are a result of the anaerobic biochemical breakdown of the waste ... -
Long term water balance and estuarine mechanism simulation of the Mfolozi River floodplain, South Africa.
(2013)The St Lucia estuarine lake is a World Heritage Site due to its size and its unique ecology. In the past, the mouths of the Mfolozi River and the St Lucia Lake were combined. During drought periods, the combined mouth ... -
Management and production techniques in the manufacturing and service industries and how it relates to the construction industry.
(2011-01-21)This dissertation is concerned with the future of the construction industry in South Africa and the ability to improve. Continuous growth is predicted through to the year 2015 and beyond, it is considered that to meet ... -
A mathematical model development for simulating in-stream processes of non-point source pollutants.
(2018)In coming years, chronic water stress is inevitable owing to the unavailability of fresh water. This situation is occasioned by rapid urbanisation, climate change, rising food demand, and production. The increasing rate ... -
Maximising the photobiological production of hydrogen using leachate, while monitoring algal photosynthesis using pam fluorometry.
(2014)Hydrogen is universally known as the most efficient renewable energy source capable of meeting global energy demands. Chlamydomonas reinhardtii has the ability to produce biohydrogen during the metabolic engineering of ... -
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 ... -
Modelling hydrological responses to land use and climate change : The Mfolozi Catchment.
(2012)St. Lucia is South Africa’s largest and most important estuarine system. The Mfolozi and Mkuze catchments provide the main source of water to the system. Regional climate change may influence future water and sediment ... -
Modelling in ungauged catchments using PyTOPKAPI : a case study of Mhlanga catchment.
(2018)Hydrological modeling of rainfall-runoff processes is a powerful tool used in various water resources applications, including the simulation of water yield from ungauged catchments. Many rivers in developing countries are ... -
Modelling of the water balance and nutrient dynamics of Mhlanga Estuary.
(2011-01-19)Waste water discharge into a temporary open/closed estuary (TOCE) system introduces two main concerns namely (1) the effects on the water balance of the system (quantity) and (2) the effects on the nutrient dynamics (water ... -
Modelling sand bypass schemes on the KwaZulu-Natal coastline.
(2015)Coastal structures such as breakwaters cause a disruption of longshore sediment transport along coastlines. The result of this disruption creates sand accumulation up-drift and beach erosion down-drift of these structures. ... -
Modelling the influence of varying sediment sources on coastlines.
(2019)Coastal erosion is of concern to developed shorelines worldwide and has largely intensified due to anthropogenic influences. Sea-level rise, reductions in sediment supply and changes to wave behaviour due to changes in ... -
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 ... -
A new approach to the polyaxial stress numerical analysis of underground openings.
(2012)The traditional design methodologies for tunnel and underground excavations are divided in to three categories: Empirical, Analytical, and Observational approaches, whereas in the last years the Numerical approach has ... -
Nitrate removal from treated landfill leachate using a mix of vegetable waste and immature compost as a carbon source (simulation) in batches.
(2014)The aim of this dissertation was to investigate how effective the process of removing nitrates from treated leachate, and if it is possible to apply to a landfill treatment plant. The leachate is high strength landfill ... -
Nitrate removal using compost and pine bark as a carbon source.
(2010-09-03)Emissions resulting from waste degradation processes have a high polluting potential and are responsible for negative impacts on the environment. Landfill leachate is hazardous for the human health and the environment ...
