Hydraulic properties of the vadose zone at two typical sites in the Western Cape for the assessment of groundwater vulnerability to pollution
(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)This thesis focusses on the hydrocarbon potential of the Prince Albert Formation in terms of its shale gas potential. Unconventional gas production from hydrocarbon-rich shale formations, known as “shale gas”, is one of ... -
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) ... -
Implications of the geological structure of the Qoqodala dolerite ring complex for groundwater dynamics
(University of the Western Cape, 2008)The chief aim of this project is to investigate the groundwater flow dynamics of the various fractured-rock aquifers (deep and shallow) associated with Karoo dolerite ring complexes in the Qoqodala area (northeast of ... -
Improving estimation of precipitation and prediction of river flows in the Jonkershoek mountain catchment
(University of the Western Cape, 2016)Rainfall is the main input into the land phase of the hydrological cycle which greatly determines the available water resources. Accurate precipitation information is critical for mountain catchments as they are the main ... -
Infiltration, runoff and particle mobilization on canola fields at langgewens experimental farm, Mooreesburg, Western Cape
(2013)The primary origin of this project is due to a high demand for freshwater supply in the Berg Water Management Area (WMA). Most of the Berg WMA`s freshwater supply does not live up to the high ecological standards. This is ... -
The influence of canopy cover and cultivar on rates of water use in apple orchards in the Western Cape Province, South Africa
(University of the Western Cape, 2020)Water availability and climate related issues are some of the greatest crop production risks to irrigated agriculture in arid regions. In South Africa, for example, the increasing frequency and severity of droughts related ...
