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 ... -
The influence of clay diagenesis on the petrophysical properties of sandstone reservoirs in the Pletmos Basin Offshore South Africa
(University of Western Cape, 2020)Pletmos Basin is a Mesozoic half graben located in the southern part of South Africa and has undergone numerous tectonic changes which involve alteration of structure and reworking of sediments. Clay diagenesis has become ... -
Influences of river flows on recruitment success of Fynbos riparian vegetation along selected high gradient streams in the Western Cape, South Africa
(University of the Western Cape, 2014)Riparian vegetation occurs in two distinct zones, the wet bank and the dry bank. Knowledge on how the flow regime influences the zonal structure of riparian vegetation is required to mitigate the adverse effects of water ... -
Institutional overlaps in water management in the Eerste River catchment
(University of the Western Cape, 2005)In this minithesis I have investigated overlapping mandates as a source of management failure in water management in South Africa in general and Eerste River Catchment in particular. I analysed major legislation which deals ... -
Integrated approach to solving reservoir problems and evaluations using sequence stratigraphy, geological structures and diagenesis in Orange Basin, South Africa
(University of the Western Cape, 2010)Sandstone and shale samples were selected within the systems tracts for laboratory analyses. The sidewall and core samples were subjected to petrographic thin section analysis, mineralogical analyses which include x-ray ... -
Integrated approach to solving reservoir problems and evaluations using Sequence Stratigraphy, Geological Structures and Diagenesis in Orange Basin, South Africa"
(University of the Western Cape, 2010)The use of integrated approach to evaluate reservoir rock quality and source rock potential is becoming increasingly important in petroleum geology. This approach was employed to unravel the reason for variable reservoir ... -
