Applicability of big data analytics to support groundwater management in Southern Africa
(University of the Western Cape, 2022)Groundwater is a vital resources for member states in the Southern African Development Community (SADC). However, sustainable managing groundwater resources in SADC is a challenge. Amongst the many issues facing groundwater ... -
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 ... -
Assessing effectiveness of groundwater remediation technologies to a coastal aquifer within an urban environment in South Africa
(University of the Western Cape, 2022)The study aimed to assess the effectiveness of Reverse Osmosis technology as an example of ex-situ groundwater remediation technologies. The Cape Flats Aquifer System, an urban coastal system, was used as a case study. ... -
Assessing hydrogeology of springs in Heuningnes Catchment in South Africa
(University of the Western Cape, 2022)Springs have been a significant source of water for flora and fauna since the beginning of human history and, in some circumstances, the only source capable of supplying enough water to sustain domestic and agricultural ... -
Assessment of groundwater level fluctuation trends in Grootfontein dolomite Aquifer, North West Province, South Africa
(University of the Western Cape, 2022)Groundwater level decline is a problem experienced in aquifers with more than one groundwater user such as the Grootfontein dolomite aquifer in the North West Province of South Africa. This study assessed groundwater ... -
Constraining the stratigraphy and paleotectonic development of the Cango Caves and Kansa Groups (Western Cape, South Africa) using detrital zircon and whole-rock geochemistry
(University of the Western Cape, 2022)The Saldania Belt is a Neoproterozoic to early Paleozoic low-grade orogenic belt that borders the southern and southwestern margins of the Kalahari Carton. It forms part of the Neoproterozoic Pan-African and Brasiliano ... -
Developing an integrated remotely sensed framework for the detection and monitoring of seasonally-flooded wetlands in semi-arid environments of southern Africa
(University of the Western Cape, 2022)Wetlands are among the most important ecosystems on earth; they cover approximately 4-6% of the earth’s surface and offer critical eco-hydrological services. However, these ecosystems are under threat from anthropogenic ... -
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 ... -
The establishment of the long-term rainfall trends in the annual rainfall patterns in the Jonkershoek Valley, Western Cape, South Africa
(University of the Western Cape, 2008)The overall aim of this project was to establish whether there is a long-term decline of rainfall collected in rainfall gauges within the Jonkershoek Valley that have the longest and best quality records. -
Geomorphic analysis of river character and behaviour in three semi-arid, mountainous catchments in the Eastern Cape, South Africa
(University of Western Cape, 2019)The analysis of what controls why rivers are the way they are, and how and why they change is crucial in predicting river dynamics and deriving classification systems that can assist management. A variety of factors control ... -
GIS and remote sensing-based integrated modelling of climate and land use change impacts on groundwater quality: Cape Flats Aquifer, South Africa
(University of Western Cape, 2021)The need to ensure groundwater security is vital, particularly in urban areas. Assessing the impact of land use and climate variables on groundwater quality can help improve sustainable management. The vulnerability mapping ... -
Green drop programme in South Africa: The role of institutional commitment in sustainable water resources management: Western Cape, South Africa
(University of the Western Cape, 2022)Incentive-based regulation is a key driver of change to improve wastewater management and sustainable water resource management. Although the Green Drop Certification program has existed since 2009, no academic studies ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
Rainfall induced transient pressure wave mechanisms and pore water pressure dynamics in tailings
(University of the Western Cape, 2023)Tailings Storage Facilities are some of the largest engineered structures responsible for the containment of mining waste, yet some physical/hydrological processes causing slope instability are still poorly understood. ... -
