An analysis of sustainability of communally-managed rural water supply systems in Zimbabwe
(University of the Western Cape, 2016)Sustainability of rural water supply systems is a major development challenge in most developing countries including Zimbabwe. This thesis aimed to analyse the sustainability of communally managed rural water supply systems ... -
The palaeo environment and depositional facies of the drift section of Block 3A/4A in the Orange Basin, West Coast Offshore South Africa
(University of the Western Cape, 2017)The Orange Basin is underexplored and has shown proven hydrocarbon reserves with the potential for further discoveries. This study is aimed at describing the depositional facies and palaeoenvironment of the drift section ... -
Hydrogeophysical characterisation of shallow coastal aquifers in the Western Cape, South Africa
(University of the Western Cape, 2017)Coastal aquifers present a key groundwater resource for freshwater supply in many coastal zones of Africa, and its availability is largely driven by the physical hydrogeological properties. An understanding of the aquifer ... -
Using geostatistical-hydrogeological approach to develop groundwater monitoring system in South Western Karoo, South Africa
(University of the Western Cape, 2017)Groundwater in the South Western Karoo plays a vital role in the overall water supply in the region. However, this resource is vulnerable to impacts from anthropogenic and natural activities. Mitigating the impacts on ... -
An assessment of water use by Acacia longifolia trees occurring within the hillslopes and riparian zone of the Heuningnes Catchment, Western Cape
(University of the Western Cape, 2018)The increasing expansion of Acacia longifolia trees along the riparian zones in South Africa demands an urgent intervention as the species is listed in the National Environmental Management: Biodiversity Act (2004). This ... -
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 ... -
Basin Evaluation of Turonian Deposits in the Lower Congo Basin using outcrops, cores, well-logs and seismic
(University of the Western Cape, 2017)This manuscript presents a review of the Turonian series of the Congolese Coastal Basin using outcrop, core, well-logs and seismic data in order to provide a comprehensive model for the series and increase the oil recovery. ... -
Conceptualization of urban hydrogeology within the context of water sensitive urban design: case study of Cape Flats Aquifer
(University of the Western Cape, 2018)Urban hydrogeology can be used to facilitate a decision-making process regarding the implementation of water sensitive urban design (WSUD) to manage water systems of periurban cities. This thesis was aimed at providing ... -
Investigating groundwater governance arrangements for unconventional gas exploration and production in main Karoo Basin, South Africa
(University of the Western Cape, 2016)South Africa relies on coal and imported crude oil for most of its energy. The possible production of shale gas in the main Karoo Basin of South Africa provides a potential opportunity to diversify the primary energy mix. ... -
Improving estimation of precipitation and prediction of river flows in the Jonkershoek mountain catchment
(University of the Western Cape, 2016)Rainfall is the main input into the land phase of the hydrological cycle which greatly determines the available water resources. Accurate precipitation information is critical for mountain catchments as they are the main ... -
Hydrological Characterisation of Wetlands: Understanding wetlands-catchment linkages
(University of the Western Cape, 2017)This study explores the hydrological processes of selected wetlands in four different catchments in South Africa (the Nuwejaars River in the Western Cape which has the Elandsdrift-Wiesdrift wetland; the Mohlapetsi river ... -
Analysis of monthly MOD16 evapotranspiration rates at sites with different climatic characteristics; Heuningnes and Letaba catchments in South Africa
(University of the Western Cape, 2017)Evapotranspiration (ET) is an important component of the water cycle that is estimated to return about 60% of precipitation back to the atmosphere. Actual ET can be estimated using remote sensing techniques and ground-based ... -
A comparative analysis of long-term variations of temperature and rainfall in rural and urban areas, and their effects on the estimation of design storms in Kenya
(University of the Western Cape, 2016)My Thesis aimed at expanding the current knowledge on how variations of temperature characteristics including the possible existence of urban heat islands (UHI) over urban areas of Kenya could be influencing rainfall ... -
2D Geomechanical Model for an Offshore Gas Field in the Bredasdorp Basin, South Africa.
(University of the Western Cape, 2016)This thesis provides a 2D geomechanical model for the K-R field, Bredasdorp Basin and describes the workflow and process to do so. This study has a unique density correction software applied to density data, prior to the ... -
A comparison of black-oil versus compositional simulation methods for evaluating a rich gas-condensate reservoir
(University of the Western Cape, 2016)Over time, researchers have endeavoured to use conventional black-oil (BO) models to model volatile-oil and gas-condensate reservoirs as accurately as possible, with variable levels of success. The black-oil approach ... -
Reservoir Characterization using Genetic Inversion and Seismic attributes of Block 1 Orange Basin, Offshore South Africa
(University of the Western Cape, 2016)Block 1, Orange Basin is located offshore west coast South Africa. This study is focused on providing a solution to performing reservoir characterization in areas where well data is scanty by generating reservoir models ... -
Investigation of deep groundwater flow systems in the Main Karoo Basin of South Africa
(University of the Western Cape, 2017)The improvement in hydraulic fracturing techniques resulted in the exploitation of natural gas associated with low-permeability of organic-rich shale formations in the United States. South Africa has prospective shale gas ... -
The use of GIS, statistical and risk assessment tools to evaluate aquifer vulnerability to potential contaminants
(The University of the Western Cape, 2017)An aquifer is a body of permeable rock which can contain or transmit groundwater. It is a low cost water supply for domestic and agricultural use. Routine monitoring of aquifers is important to prevent contamination and ... -
