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 ... -
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 ... -
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 ... -
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. ... -
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 ... -
Using citizen science in monitoring groundwater levels to improve local groundwater governance, West coast, South Africa
(University of the Western Cape, 2019)Monitoring of groundwater levels provides a basis for assessing the availability of water in aquifers, thereby informing the decisions on abstraction and uses of such water for various purposes. It provides an understanding ... -
Characterizing water quality of rivers and underlying aquifers in the Nuwejaars Catchment, South Africa
(University of Western Cape, 2020)Non-perennial rivers are the main source of surface water in drylands. These rivers are unpredictable and highly variable in terms of flow regime and water quality. Despite their abundance, and importance in the landscape, ... -
Investigating hydrogeochemical processes of groundwater, Heuningnes Catchment, South Africa
(University of the Western Cape, 2020)This study was conducted to investigate hydrogeochemical processes controlling the evolution of groundwater chemistry and their influence on water quality in the Heuningnes Catchment. The role or influence of hydrogeochemical ... -
The use of derivative analysis and aquifer parameter estimation to refine a conceptual model: A case study approach, Western Cape, South Africa
(University of Western Cape, 2021)Hydrogeological characterization of an aquifer system is a first step to determine groundwater quantity, yield potential, socio-economic value, storage capacity and aquifer transmissivity properties of an aquifer as a water ... -
Environmental modelling of wetland distribution in the Western Cape, South Africa: A climate change perspective
(University of Western Cape, 2021)Wetlands have been recognised as one of the most intrinsically valuable and threatened ecosystems in the world. Global estimates indicate that wetlands are being lost or transformed at a rapid rate, exacerbated by projected ... -
Effects of flood dynamics on island geomorphology in a large mixed bedrock-alluvial anabranching river: a case study of the Vaal River near Parys.
(University of the Western Cape, 2021)Rare-infrequent magnitude floods of shorter duration events are significant natural hazards and play a key role in shaping river channel and island geomorphology. For a given river or channel, there is a relationship between ... -
Multispectral remote sensing of the impacts of drought and climate variability on water resources in semi-arid regions of the Western Cape, South Africa
(University of Western Cape, 2021)The occurrence of droughts is a threat to global water resources and natural ecosystems, with the impact being more profound in semi-arid environments. The frequency of droughts is likely to increase because of climate ... -
Evaluating telemetry system of the Phalaborwa water treatment works process in Lepelle northern water
(University of Western Cape, 2021)Water is a strategic resource critical for basic human needs and for sustaining key economic sectors, including various emerging small businesses. The significance of water to everyday life become apparent mainly during ... -
The use of remote sensing data for assessing water quality in wetlands within the Limpopo River Basin
(University of the Western Cape, 2021)Wetlands are unique ecosystems that are acknowledged among the world’s most productive and valuable ecosystems. They are recognized as being essential to sustainable development and human welfare due to their unique ... -
Remote sensing drought impacts on wetland vegetation productivity at the Soetendalsvlei in the Heuningnes Catchment, South Africa
(University of Western Cape, 2021)This work aimed at assessing the response of wetland vegetation productivity to the 2014-2017 climate-induced drought at the Soetendalsvlei wetland system in the Western Cape province of South Africa. To achieve this ... -
Developing a remotely-sensed framework for fire monitoring in the Western Cape, South Africa
(University of Western Cape, 2021)For a long time, fire dynamics has been misunderstood and viewed as either a destructive force or an ecological necessity. The Western Cape Province in South Africa experiences the frequent occurrence of fires, due to the ... -
Understanding spatial patterns of dispersal and deposition of fine sediment and adsorbed phosphates in the Wiesdrift Wetland on the Nuwejaars River, Cape Agulhas
(University of the Western Cape, 2021)River catchments in agricultural areas are strongly influenced by runoff from cultivated or grazed fields, and nutrient loading of these fields can result in large quantities of nitrates and phosphates being transported ... -
Effects of acid concentration on the extraction of rare earth elements from South African Coal Fly Ash
(University of Western Cape, 2021)Coal is seen as a reliable and secure energy source in many countries around the world despite the development of a number of alternative sources of energy. A rise in global energy demand has led to an increase in coal ... -
