Hydraulic properties of the vadose zone at two typical sites in the Western Cape for the assessment of groundwater vulnerability to pollution
Samuels, Donovan (University of the Western Cape, 2007)Aquifer vulnerability assessment is increasingly becoming a very significant basis in order to fulfill the water demands in South Africa. Knowledge of soil hydraulic properties that consists of the soil water retention and ... -
Implications of the geological structure of the Qoqodala dolerite ring complex for groundwater dynamics
Nhleko, Olivia Lebogang (University of the Western Cape, 2008)The chief aim of this project is to investigate the groundwater flow dynamics of the various fractured-rock aquifers (deep and shallow) associated with Karoo dolerite ring complexes in the Qoqodala area (northeast of ... -
Institutional overlaps in water management in the Eerste River catchment
Nleya, Ndodana (University of the Western Cape, 2005)In this minithesis I have investigated overlapping mandates as a source of management failure in water management in South Africa in general and Eerste River Catchment in particular. I analysed major legislation which deals ... -
Investigating channel change in relation to landuse change in the Klein Berg River, Tulbagh
Esau, Mandy Anita (University of the Western Cape, 2005)The Klein Berg River catchment is intensely cultivated with orchards, vineyards and wheat, while also ensuring a water supply to the main urban center, Tulbagh, and the two conservation areas (Waterval and Groot Winterhoek). ... -
Modelling the behaviour and fate of priority pesticides in South Africa
Maharaj, Simone (University of the Western Cape, 2005)The use of pesticides poses a serious threat to the limited water resources of South Africa. The amounts which are not taken up by crop plants, are often washed away by runoff into surface waters, or leached through the ... -
Optimisation of selective extraction techniques as a tool for geochemical mapping in the Southern Africa region
Akinyemi, Segun Ajayi (University of the Western Cape, 2008)The complex nature and composition of regolith cover in Southern Africa is a major challenge to geochemical mapping for concealed mineralization. Some of the setbacks to successful geochemical exploration may be ascribed ... -
Perceptions of water scarcity: the case of Genadendal and outstations
Noemdoe, Simone Beatrice (University of the Western Cape, 2006)The water resources management regime has shifted from one focusing almost exclusively on augmenting supply to one where ensuring access, equity and sustainability are an integral part of the process. A growing demand for ... -
Petrographic characterization of sandstones in borehole E-BA1, Block 9, Bredasdorp Basin, Off-Shore South Africa
Van Bloemenstein, Chantell Berenice (University of the Western Cape, 2006)The reservoir quality (RQ) of well E-BA1 was characterized using thin sections and core samples in a petrographic study. Well E-BA1 is situated in the Bredasdorp Basin, which forms part of the Outeniqua Basin situated in ... -
The petrophysical analysis and evaluation of hydrocarbon potential of sandstone units in the Bredasdorp Central Basin
Olajide, Oluseyi (University of the Western Cape, 2005)This research was aimed at employing the broad use of petrophysical analysis and reservoir modelling techniques to explore the petroleum resources in the sandstone units of deep marine play in the Bredasdorp Basin. -
Petrophysical evaluation of the Albian Age gas bearing sandstone reservoirs of the O-M field, Orange Basin, South Africa
Opuwari, Mimonitu (University of the Western Cape, 2010)Petrophysical evaluation of the Albian age gas bearing sandstone reservoirs of the O-M field, Offshore South Africa has been performed. The main goal of the thesis is to evaluate the reservoir potentials of the field through ... -
Porosity and permeability distribution in the deep marine play of the central Bredasdorp Basin, Block 9, offshore South Africa
Ojongokpoko, Hanson Mbi (University of the Western Cape, 2006)This study described porosity and permeability distribution in the deep marine play of the central Bredasdorp Basin, Block 9, offshore South Africa using methods that include thin section petrography, X-ray diffraction, ... -
Pre-paid water metering: social experiences and lessons learned from Klipheuwel pilot project, South Africa
Kumwenda, Moses (University of the Western Cape, 2006)This thesis examined a pre-paid water metering pilot project which was implemented in Klipheuwel , Cape Town, South Africa in 2001. It was anticipated that the implementation of pre-paid water meters would help improve the ... -
A preliminary understanding of deep groundwater flow in the Table Mountain group (TMG) aquifer system
Netili, Khangweleni Fortress (University of the Western Cape, 2007)The Table Mountain Group (TMG) Aquifer is the second largest aquifer system in South Africa, after dolomites. This aquifer has the potential to be a signinficant source of water for the people of the Western Cape. The ... -
Regional groundwater monitoring in the Olifants-Doorn water management area
Seward, Paul (University of the Western Cape, 2006)The aim of this investigation was to provide a framework or strategy for prioritising and implementing regional groundwater monitoring in the Olifants-Doorn Water Management (WMA) area. The general approach was to attempt ... -
