Application Of environmental tracer methods to conceptualize groundwater recharge, West Coast, South Africa
(University of the Western Cape, 2019)Drought and climate change will have adverse consequence for freshwater resources in water stressed South Africa. Diminishing surface water reserves increases the demand to exploit groundwater resources. The drought ... -
Investigating associations between fluvial style and the characteristics and distribution of geomorphic units in non-perennial rivers
(University of the Western Cape, 2019)Although non-perennial rivers are the most dominant river type in arid and semi-arid areas, far outnumbering perennial rivers, recent reviews have shown that the knowledge base supporting non-perennial river research is ... -
Identification and estimation of ecologically relevant flow indices for non-perennial rivers, South Africa
(University of the Western Cape, 2019)The importance of environmental flows and establishing the balance between hydrological response and ecological functioning of rivers has been globally recognised. Methods for determining environmental flows range from ... -
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 ... -
Using coupled atmospheric-unsaturated zone model to quantify groundwater recharge to the Table Mountain Group Aquifer system, George, South Africa
(University of the Western Cape, 2019)The current study aimed at providing groundwater recharge estimates in a fractured rock aquifer environment that is occupied by pine plantation and indigenous forests in order to improve the understanding of the effect of ... -
The use of remote sensing data to monitor pools along non-perennial rivers in the Western Cape, South Africa.
(University of the Western Cape, 2019)The lack of monitoring of non-perennial rivers is a major problem for water resources management, despite their significance in satisfying agricultural, economic and recreational needs. Pools in non-perennial rivers are ... -
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. ... -
Assessing the influence of groundwater recharge mechanism on non-perennial river systems, Tankwa Karoo, South Africa
(University of the Western Cape, 2019)In South Africa and neighbouring countries such as Zimbabwe, Botswana, Angola, and Namibia, most river systems are non-perennial due to semi-arid or arid climatic characteristics. In such river systems, the interaction ... -
An assessment of the river flow contributions of tributaries and the effects of floodplain wetlands on spatio-temporal variations of river flows in the Nuwejaars river catchment, Cape Agulhas
(University of the Western Cape, 2019)Improved knowledge is required on the quantity and source of water resources, particularly evident during periods of drought currently being faced in South Africa. There is inadequate knowledge with regards to the flood ... -
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 ... -
Geological modelling for carbon storage opportunities in the Orange Basin South Africa
(University of the Western Cape, 2019)This study investigates the viability of the sedimentary deposits in the Northern Orange basin for carbon storage and sequestration. A combination of geological modelling, petrographic and geochemical techniques are used ... -
Assessing hydrogeological characteristics to establish influence of aquifer-river interaction in non-perennial river systems, Heuningnes catchment
(University of the Western Cape, 2019)Over half of total flows in the global river network are composed of non-perennial rivers. This indicates the importance of non-perennial river systems in supporting the biodiversity. It has been established that groundwater ... -
Assessing the effect of the Kars Wetland on flow attenuation in the Cape Agulhas, South Africa
(University of the Western Cape, 2019)The Kars has a well-defined channel along the 62 km stretch from its sources in the Bredasdorp Mountains. After entering the Agulhas plain which has a very low gradient, this river changes into a triangular shaped wetland. ... -
An integrated study of the early cretaceous (Valanginian) reservoir from the Gamtoos Basin, offshore South Africa with special reference to seismic cacies, 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 ... -
Assessing the change in hydro-geochemical properties of fly ash over time when disposed into opencast coal mines in Mpumalanga, South Africa
(University of the Western Cape, 2019)Eskom supplies to 95% of South Africa’s energy needs and it primarily comes from coal combustion at their coal–fired power stations. Large volumes of fly ash are generated at these coal-fired power stations as a by-product ... -
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 ... -
The morphodynamic characteristics of erosional headcuts in Palmiet (Prionium serratum) wetlands
(University of the Western Cape, 2018)Gully erosion and headcut migration has been at the crux of wetland degradation in South Africa. The resulting erosion and draining effect has seen more than 50% of wetlands in the country degraded. This study investigated ... -
The effects of minerals on reservoir properties in block 3A and 2C, within the orange basin, South Africa.
(University of the Western Cape, 2018)The reservoir quality of the Orange Basin, offshore South Africa is known to be immensely impaired by the presence of authigenic minerals. The collective effects of burial, bioturbation, compaction and chemical reactions ... -
