Application of fluid electrical conductivity logging for fractured rock aquifer characterisation at the University of the Western Cape's Franschhoek and Rawsonville research sites
Lasher, Candice (University of the Western Cape, 2011)Characterisation of fractured rock aquifers is important when dealing with groundwater protection and management. Fractures are often good conduits for water and contaminants, leading to high flow velocities and the fast ... -
Assessment controls on reservoir performance and the affects of granulation seam mechanics in the Bredasdorp Basin, South Africa
Schalkwyk, Hugh Je-Marco (University of the Western Cape, 2006)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 ... -
Can Acacia Karroo and Boscia Albitrunca be used in the biogeochemical prospecting for gold :a case study at the Blue Dot Mine, Amalia, Northwest province, South Africa
Mshumi, Unathi (University of the Western Cape, 2006)In areas of transported overburden there is frequently a weak relationship between soil and the underlying mineralized bedrock. Vegetation has the capability to absorb metals from the underlying substrate via its extensive ... -
The challenge of implementing integrated water resources management (IWRM) in the Lower Okavango River Basin, Ngamiland district, Botswana
Kgomotso, Phemo Karen (University of the Western Cape, 2005)Water resources management practice has undergone changes in management approaches and principles over time. It was previously characterised by what scholars refer to as the hydraulic mission where ‘extreme engineering’ ... -
Comparative study of the chemostratigraphic and petrophysical characteristics of wells A-A1, A-L1, A-U1 and A-I1 in the Orange Basin, South Atlantic Margin, Offshore South Africa
Bailey, Carlynne (University of the Western Cape, 2009)Many hydrocarbon reservoirs are situated in barren sequences that display poor stratigraphic control. Correlation between the wells can become extremely difficult and traditional correlation techniques can prove to be ... -
A comparison of SAAS and chemical monitoring of the rivers of the Lesotho Highlands Water Project
Rajele, Molefi Joseph (University of the Western Cape, 2004)The Lesotho Highlands Development Authority routinely uses the South African Scoring System version 4 (SASS4) in conjunction with water chemistry to monitor water quality of rivers in the Lesotho Highlands Water Project ... -
Development of a conceptual model for ash dump system using hydraulic and tracer test techniques
October, Adolf Gerswin (University of the Western Cape, 2011)Coal provides for 77% of South Africa’s primary energy needs and is therefore a major resource that supports the socio-economic needs of South African citizens. Power stations are the major consumers of coal in South Africa ... -
Development of local sampling and monitoring protocol for radioactive elements in fractured rock Acquifers in South Africa using a case study in Beaufort West
Mahed, Gaathier (University of the Western Cape, 2009)The aim of this study was to test whether one could use the same methods as used for sampling heavy metals and apply them to radioactive elements. Furthermore a sampling protocol was developed, the first of its kind, for ... -
The ecohydrology of the Franschoek Trust Wetland: water, soils and vegetation
Kotzee, Ilse (University of the Western Cape, 2010)The research was driven by a need to increase the knowledge base concerning wetland ecological responses, as well as to identify and evaluate the factors driving the functioning of the Franschhoek Trust Wetland. An ... -
The establishment of the long-term rainfall trends in the annual rainfall patterns in the Jonkershoek Valley, Western Cape, South Africa
Moses, Godfrey (University of the Western Cape, 2008)The overall aim of this project was to establish whether there is a long-term decline of rainfall collected in rainfall gauges within the Jonkershoek Valley that have the longest and best quality records. -
Exploration geochemical mapping in the north-eastern sector of the Morokweng impact structure, South Africa
Yang, Jin (University of the Western Cape, 2006)The Morokweng impact structure which is located in the North West province of South Africa, has attracted attention as a potential host for Ni-PGE mineralization. Geochemical exploration techniques using hydroxylamine ... -
The fate of microbial contaminants in the subsurface with a South African case study
Rajkumar, Yasmin (University of the Western Cape, 2009)The time bound agenda of the Millennium Development Goals (MDG's) aims at reducing poverty, extending gender equality and advancing opportunities for health and education by addressing current and future water resource and ... -
A geographic information systems approach to the identification of Table Mountain group aquifer "type areas" of ecological importance
Fortuin, Mildred (University of the Western Cape, 2004)The Table Mountain group aquifer system has the potential to be an important supply of water. Although the aquifer system is used to some extent, a number of aspects relating to the aquifer system are poorly understood and ... -
Groundwater Dependence of Aquatic Ecosystems associated with the Table Mountain Group Aquifer
Roets, Wietsche (University of the Western Cape, 2008)Results from this study enables a better understanding of groundwater surface water interactions in the TMG, particularly regarding aquatic ecosystems. It has also highlighted the necessity to do proper impact assessments ... -
Groundwater recharge estimation in Table Mountain Group aquifer systems with a case study of Kammanassie area
Wu, Yong (University of the Western Cape, 2005)The focus of this study was on recharge mechanisms and recharge estimation within the Table Mountain Group area. The study evaluated recharge processes and recharge estimation methods in the Table Mountain Group aquifer systems. -
Groundwater resource evaluation and protection in the Cape Flats, South Africa
Adelana, Segun Michael Adegboyega (University of the Western Cape, 2010)The analysis of geologic, hydrologic and hydrogeologic data interpreted to give the characteristics of the Cape Flats aquifer showed the quality of groundwater from the aquifer is suitable for development as a water resource. ... -
