Application of enviromental and hydrochemical analysis to characterize flow dynamics in the Sakumo Wetland, Ghana
(University of the Western Cape, 2018)This research focused on understanding the current hydrogeology of the Sakumo wetland by developing a conceptual flow model and simulating the groundwater flow system. The purpose of the model is to assist in understanding ... -
An integrated approach to understanding the geological controls on gas escape and migration pathways in offshore northern Orange Basin, South Africa.
(University of the Western Cape, 2017)The use of an integrated approach in science has gained more prominence recently because it is thorough and provides a dynamic perspective from which scientific problems can be investigated and solutions proffered. Here, ... -
Opportunity for implementing reclaimed water for domestic applications in South Africa: institutional engagement and public perceptions
(University of the Western Cape, 2017)Water scarcity which impacts negatively on humans, as well as on the natural environment, is a real problem facing developed and developing countries. The reuse of wastewater is a critical component of the effective and ... -
Geochemical, Sedimentological and Mineralogical Study of Sediments along Coastal Areas of Abu Dhabi, United Arab Emirates (UAE): Implications for Provenance, Depositional Environment, Heavy Minerals and Radiogenic Elements Contamination
(University of the Western Cape, 2017)This study describes sedimentological, geochemical and mineralogical results of the beach sediments of Abu Dhabi in the United Arab Emirates in order to understand the provenance, depositional environment and the level of ... -
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 ... -
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 ... -
Assessment of sustainable groundwater utilization with case studies from semi-arid Namibia
(University of the Western Cape, 2016)The thesis addresses sustainability of groundwater utilization in arid and semiarid regions of Namibia. Recharge in this hydrogeological setting occurs as discrete events to aquifers that are bounded in extent. Case studies ... -
Rethinking groundwater governance in South Africa
(University of the Western Cape, 2015)Governance is essentially the process whereby organisations or networks of organisations exercise their authority. It describes how a body with authority makes or does not make decisions, and how it implements - or does ... -
Spatial and temporal variation of inundation in the Okavango Delta, Botswana; with special reference to areas used for flood recession cultivation
(University of the Western Cape, 2015)The Okavango Delta is recognized as one of the famous inland wetlands and its sustainable use is important for socio-economic development of Botswana. The Okavango delta comprises permanent swamps, seasonal swamps, and ... -
Testing and evaluation of artesian aquifers in Table Mountain Group aquifers
(University of the Western Cape, 2014)The Table Mountain Group (TMG) Aquifer is a huge aquifer system which may provide large bulk water supplies for local municipalities and irrigation water for agriculture in the Western Cape and Eastern Cape Provinces in ... -
Evaluation of groundwater flow theories and aquifer parameters estimation
(University of the Western Cape, 2014)This thesis deals with some fundamental aspects of groundwater models. Deterministic mathematical models of groundwater are usually used to simulate flow and transport processes in aquifer systems by means of partial ... -
NON-INVASIVE CHARACTERIZATION OF UNSATURATED ZONE TRANSPORT IN DRY COAL ASH DUMPS: A CASE STUDY OF TUTUKA, SOUTH AFRICA
(University of the Western Cape, 2013)The management of the large volumes of solid wastes produced as coal combustion residue is of particular concern due to the presence of leachable metals and salts which may constitute a long term environmental risk and ... -
Assessment of groundwater management for domestic use from IWRM perspective in upper Limphasa river catchment, Malawi
(University of the Western Cape, 2012)The research problem for this study is the limited and unsuccessful implementation of the IWRM concept. This thesis has argued that comprehensive assessment of physical and socioeconomic conditions is essential to provide ... -
Hydraulic properties of the Table Mountain Group (TMG) aquifers
(University of Western Cape, 2008)Research findings in current study provide a new insight into the fractured rock aquifers in the TMG area. Some of the results will have wide implications on the groundwater management and forms a solid basis the further ... -
Effects of land-cover - land-use on water quality within the kuils - Eerste River Catchment
(University of Western Cape, 2012)The most significant human impacts on the hydrological system are due to land-use change. The conversion of land to agricultural, mining, industrial, or residential uses significantly alters the hydrological characteristics ... -
