High-grade metamorphism, anatexis and deformation of metasedimentary rocks from the Kamiesberg Group near Kliprand, Southern Bushmanland Domain, Namaqua Metamorphic Province
(University of the Western Cape, 2022)Migmatitic metapelites of the Kamiesberg Group are distributed throughout the central Bushmanland Domain (Namaqua Metamorphic Province) which is otherwise dominated by felsic gneisses. This study focusses on an outcrop ... -
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 ... -
Hydraulic properties of the Table Mountain group (TMG) aquifers
(University of the Western Cape, 2006)The Table Mountain Group (TMG), located at the southmost cape of African Continent, is one out of three major regional aquifer systems in South Africa, which has a potential of bulk water supply to meet the requirements ... -
Hydraulic properties of the vadose zone at two typical sites in the Western Cape for the assessment of groundwater vulnerabilitv to pollution
(University of the Western Cape, 2007)Aquifer vulnerability assessment is increasingly becoming a very significant basis in order to fulfil the water demands in South Africa. Knowledge of soil hydraulic properties that consists of the soil water retention and ... -

(University of the Western Cape, 2007)Aquifer vulnerability assessment is increasingly becoming a very significant basis in order to fulfill the water demands in South Africa. Knowledge of soil hydraulic properties that consists of the soil water retention and ... -
Hydro geochemical characteristics of the basement aquifers in namaqualand
(University of the Western Cape, 2003)At the onset of this research programme it became apparent that there is a dearth of research studies focusing on the groundwater resources of the region. As a result, a conceptual representation of the hydrogeological ... -
Hydrocarbon potential of the Prince Albert Formation, Ecca Group in the main Karoo Basin, South Africa.
(University of the Western Cape, 2020)<Note: This thesis has been placed under permanent embargo.> -
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 ... -
Hydrogeophysical characterization of coastal aquifers for solution-based modeling, West Coast, South Africa
(University of Western Cape, 2021)The need to improve groundwater security remains critical especially in urban areas where demand for groundwater as an alternative source of water supply increases. Declining trends in availability of surface water because ... -
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 ... -
Hydrosalinity fluxes in a small scale catchment of the berg river (Western Cape)
(2008)The objective of this study was to determine the hydrosalinity fluxes associated with overland and subsurface (vadose zone) flow for different soils and land uses. For this purpose, the following data were collected during ... -
Hydrosalinity Fluxes in a Small Scale Catchment of the Berg River (Western Cape)
(University of the Western Cape, 2008)The occurrence of dryland salinity is widespread throughout semi-arid regions of the world. The sources of salts may be either rock weathering or rain deposition. Clearing of natural scrubland to make way for cultivated ... -
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 ... -
Identification and prioritization of areas for riparian buffer restoration in the Sout River catchment, Overberg District, Western Cape
(University of the Western Cape, 2023)River catchments in areas dominated by agricultural activities are prone to contamination by nutrient-rich sediments whereby phosphorus is most concern. Phosphorus binds to fine sediments and gets transported to the ... -
The identification of potential groundwater zones in the Kamiesberg region, Northern Cape province, South Africa
(University of the Western Cape, 2003)The aim of the study is to apply remote sensing techniques to identify potential groundwater resources for the Kamiesberg region. This region, with vast water shortages relies solely on groundwater and is characterized by ... -
Identifying potential areas suitable for managed aquifer recharge in Saldanha bay, Western Cape
(University of the Western Cape, 2022)The West Coast in the Western Cape of South Africa is a water-scarce area. Pressure from population and industrial growth, recurring droughts and climate change has resulted in an increasing urgency in the West Coast to ... -
Ideologies and discourses underpinning paradigms of small-scale farmer development: a critical analysis of state and non-governmental extension support programmes in uPhongolo, KwaZulu-Natal
(2013)As a means to reduce poverty particularly in rural areas, the South African government has placed great emphasis on the development of small-scale farmers into becoming commercial farmers. Central to this effort is the ... -
The impact of land use and land cover changes on wetland productivity and hydrological systems in the Limpopo transboundary river basin, South Africa
(University of Western Cape, 2021)Wetlands are highly productive systems that act as habitats for a variety of flora and fauna. Despite their ecohydrological significance, wetland ecosystems are under severe threat as a result of environmental changes (e.g. ... -
The impacts of channelisation on the geomorphology and ecology of the Kuils River, Western Cape, South Africa
(University of Western Cape, 2003)Urbanisation and storm water input in the Kuils River catchment changed the flow of the river from ephemeral to perennial. This led to flooding problems in the Kuilsrivier central business district. The river was channelised ... -
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) ...
