An integrated study of the early cretaceous (Valanginian) reservoir from the Gamtoos Basin, offshore South Africa with special reference to seismic facies, formation evaluation and static reservoir modeling
(University of the Western Cape, 2019)Integrated approaches in the study of petroleum exploration are increasingly becoming significant in recent times and have yielded much better result as oil exploration is a combination of different related topics. The ... -
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. ... -
Investigation of the acoustic impedance variations of the upper shallow marine sandstone reservoirs in the Bredasdorp basin, offshore South Africa
(University of the Western Cape, 2019)Investigation of the acoustic impedance variations in the upper shallow marine sandstone reservoirs was extensively studied from 10 selected wells, namely: F-O1, F-O2, E-M4, E-CN1, E-G1, E-W1, F-A10, F-A11, F-A13, and F-L1 ... -

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) ... -
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 ... -
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 ... -

(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 ... -
