Application of geochemical characterization, multivariate statistics and geological modelling in assessment and prediction studies on selected coal and gold mine waste in South Africa
(University of the Western Cape, 2023)Over the years, South Africa has generated vast amounts of coal fly ash and gold slime tailings, constituting over 70% of the country's waste materials. These byproducts contain elevated levels of trace metals, posing a ... -
The application of geophysical wireline logs for porosity and permeability characterisation of coal seams for coal bed methane evaluation : Waterberg Basin, South Africa
(University of the Western Cape, 2012)The fracture porosity and permeability of the Beaufort Seam 1 (BS1) and Ecca coal seams of the Waterberg Basin have been comprehensively characterised with the aid of geophysical wire‐line logs. The main aim of the thesis ... -
Application of multivariate statistics and Geographic Information Systems (GIS) to map groundwater quality in the Beaufort West area, Western Cape, South Africa
(UWC, 2013)Groundwater in arid and semi-arid areas like the Karoo region of South Africa is an important source of domestic, agricultural and industrial source of fresh water. As a scarce resource, it requires extensive quality control ... -
Application of petrophysics and seismic in reservoir characterization. A case study on selected wells, in the Orange Basin, South Africa
(University of the Western Cape, 2012)The evaluation of petroleum reservoirs has shifted from single approach to an integrated approach. The integration, analysis and understanding of all available data from the well bore and creating property models is an ... -
An approach to acquifer test pumping in fractured crystalline aquifers with a case study in Namaqualand
(University of the Western Cape, 2002)Water resources in South Africa are being stressed. Due to this concern more emphasis should be placed on determining where we can improve our existing methods for the calculation of sustainable yield. Current approaches ... -
An approach to groundwater targeting in the Springbok region, central Namaqualand, Northern Cape Province, South Africa
(University of the Western Cape, 2003)Namaqualand is a semi-arid region where water is not only a necessity and basic need, but also very much a luxury. As a consequence, various studies were undertaken to find water sources, whether surface or groundwater, ... -
An approach to groundwater targeting in the Springbok region, Central Namaqualand, Northern Cape Province, South Africa
(University of the Western Cape, 2003)Namaqualand is a semi-arid region where water is not only a necessity and basic need but also very much a luxury. As a consequence, various studies were undertaken to find water sources, whether surface or groundwater, (by ... -
Assessing different coal combustion residue backfill scenarios in opencast coal mines, Mpumalanga, South Africa
(University of Western Cape, 2020)Coal-fired power stations produce large volumes of coal combustion residues (CCRs), which are disposed of in hold ponds or landfill sites. These ash storage facilities are limited in space and are approaching the end of ... -
Assessing effectiveness of groundwater remediation technologies to a coastal aquifer within an urban environment in South Africa
(University of the Western Cape, 2022)The study aimed to assess the effectiveness of Reverse Osmosis technology as an example of ex-situ groundwater remediation technologies. The Cape Flats Aquifer System, an urban coastal system, was used as a case study. ... -
Assessing groundwater-surface water interaction as a decision-making tool licensing water use South Africa : case study area of Gevonden farm
(University of the Western Cape, 2015)Assessing groundwater-surface water interaction as a decision-making tool licensing water use South Africa: Case study area of Gevonden Farm is the title of the current study with the context that arises from the use of ... -
Assessing hydrocarbon potential in cretaceous sediments in the Western Bredasdorp Sub-basin in the Outeniqua Basin South Africa
(University of the Western Cape, 2015)The Bredasdorp Basin is one of the largest hydrocarbon producing blocks within Southern Africa. The E-M field is situated approximate 50 km west from the FA platform and was brought into commission due to the potential ... -
Assessing hydrogeological characteristics to establish influence of aquifer-river interaction in non-perennial river systems, Heuningnes catchment
(University of the Western Cape, 2019)Over half of total flows in the global river network are composed of non-perennial rivers. This indicates the importance of non-perennial river systems in supporting the biodiversity. It has been established that groundwater ... -
Assessing hydrogeology of springs in Heuningnes Catchment in South Africa
(University of the Western Cape, 2022)Springs have been a significant source of water for flora and fauna since the beginning of human history and, in some circumstances, the only source capable of supplying enough water to sustain domestic and agricultural ... -
Assessing land use-land cover changes and their effects on the hydrological responses within the Nyangores River Catchment, Kenya
(University of Western Cape, 2021)This thesis aimed at contributing knowledge on how the widespread changes in land use/cover resulting from increasing human population and their associated activities, are influencing hydrological responses in a sub-humid ... -
Assessing river-aquifer interaction for sustained water abstraction, Lower Vaal Catchment, South Africa
(University of the Western Cape, 2022)Several methods are available in the literature for the estimations of river-aquifer interactions. However, the selection of which depends on available data, local geographic and topographic conditions, the spatial and ... -
Assessing Rural domestic water demand and use for local groundwater governance during drought, Halambani area, South Africa
(University of the Western Cape, 2017)Groundwater demand (abstraction) and use during drought continues to be a vital aspect in rural areas. However, the lack of systematic data to assess the availability, demand and use of such resource in addition to lack ... -
Assessing the change in hydro-geochemical properties of fly ash over time when disposed into opencast coal mines in Mpumalanga, South Africa
(University of the Western Cape, 2019)Eskom supplies to 95% of South Africa’s energy needs and it primarily comes from coal combustion at their coal–fired power stations. Large volumes of fly ash are generated at these coal-fired power stations as a by-product ... -
Assessing the effect of the Kars Wetland on flow attenuation in the Cape Agulhas, South Africa
(University of the Western Cape, 2019)The Kars has a well-defined channel along the 62 km stretch from its sources in the Bredasdorp Mountains. After entering the Agulhas plain which has a very low gradient, this river changes into a triangular shaped wetland. ... -
