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 ... -
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, ... -
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 ... -
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 ... -
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 ... -
An assessment of the influence of water allocation on sustainable water resources management: A case study of the Nyando river basin, Kenya
(University of the Western Cape, 2018)Water problems prevalent in the Nyando River Basin are due to an ineffective water allocation system and lack of adequate conditions for implementation of sustainable integrated water resources management (IWRM) strategies. ... -
Citizen participation and water services delivery in Khayelitsha, Cape Town
(University of the Western Cape, 2011)This study analyses the relationship between the manner of citizens’ engagement with the state and the level of service delivery they experience in their everyday lives, as residents of Khayelitsha. The phenomena of so-called ... -
Constraints on the genesis of the Sandamap gold prospect, Namibia: fluid inclusion, geochronology and stable isotope studies
(University of the Western Cape, 2020)The Sandamap gold prospect is a metaturbidite shear zone-hosted gold mineralization located in the Neoproterozoic Damara Orogen 30 km northwest of the town of Usakos in Namibia with an estimated gold content of 240 000 t ... -
Effects of catchment management on physical river condition, chemistry, hydrogeomorphology and ecosystem service provision in small coastal rivers of the Western Cape
(University of the Western Cape, 2019)River systems are by nature complex and dynamic systems, which vary in structure and therefore function, and are closely connected to their landscapes. The primary aim of this thesis was to develop a systems operational ... -
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 ... -
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 ... -
Geochemical and mineralogical evaluation of toxic contaminants mobility in weathered coal fly ash: as a case study, Tutuka dump site, South Africa
(University of the Western Cape, 2011)The management and disposal of huge volumes of coal combustion by products such as fly ash has constituted a major challenge to the environment. In most cases due to the inadequate alternative use of coal fly ash, the ... -
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 ... -
Groundwater Dependence of Aquatic Ecosystems associated with the Table Mountain Group Aquifer
(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
(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
(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. ... -
Groundwater resource evaluation in Table Mountain group aquifer systems
(University of the Western Cape, 2007)Table Muntain Group has been identified as one of the major Regional Aquifers in South Africa. the vast distribution of it leads to a great diversity in its hydrogeological properties, which influences the dynamics of ... -
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 ... -
The implications of Sr and Nd isotope data on the genesis of the Platreef and associated BMS and PGE mineralisation, Bushveld Igneous Complex, South Africa
(University of the Western Cape, 2019)The Platreef is a platinum group elements (PGE) deposit located in the Northern limb of the Bushveld Igneous Complex (BIC). It is a series of mafic and ultramafic sills that are overlain by rocks from the Main Zone (MZ) ...
