An assessment of water use by riparian and non-riparian invasive alien plants and the effects on water resources at the catchment scale
(University of the Western Cape, 2023)The diversity and increasing extent of invasive alien plants (IAPs) are currently a global ecological and economic problem, especially in semi-arid regions. The introduction of IAPs worsens the strain in South Africa’s ... -
A lab based experimental study of a bioretention system to remove selected pharmaceuticals in stormwater
(University of the Western Cape, 2023)The use of treated stormwater as an alternative source of water supply in urban areas is receiving global recognition. This approach is being supported as an innovative initiative that improves urban water security and ... -
The fate and occurrence of pharmaceuticals in Cape Town’s water network
(University of the Western Cape, 2022)Thousands of pharmaceuticals, pesticides and microplastics are consumed and disposed of directly or indirectly into various water bodies globally. Which are collectively termed “contaminants of emerging concern” or CECs. ... -
A study of high-grade calc-silicate rocks in the Southern Bushmanland Domain, Namaqua Metamorphic province, including the garies wollastonite deposit
(University of the Western Cape, 2023)In the Namaqualand region, Northern Cape, South Africa, calc-silicate rocks are present in the highest-grade metamorphic zone (upper amphibolite to granulite facies) of the southern Bushmanland Domain, Namaqua Province. ... -
Spatial and temporal dynamics of flows and pools along non-perennial rivers in arid and semi-arid areas, South Africa
(University of the Western Cape, 2023)This study aimed to assess the use of multi-source remotely sensed data for monitoring the spatial distribution and dynamics of pools in two distinct sites (Touws and Molototsi) in South Africa. Various water extraction ... -
Use of remotely sensed data and spatial modelling techniques to assess impacts of different land management practices on surface water quality
(University of the Western Cape, 2023)The study uses remote sensing and statistical techniques in assessing land use land cover impacts on surface water quality in the Heuningnes Catchment, Cape Agulhas, South Africa. Firstly, a review of the advancements made ... -
Assessing the surface water - groundwater interaction and its influence on the water quality from headwaters to lowlands
(University of the Western Cape, 2023)The connections between surface water and groundwater systems remain poorly understood in many catchments throughout the world and yet they are fundamental in effectively managing water resources. Managing water resources ... -
The presence and concentration of antiretroviral drugs in different water bodies around the Western Cape
(University of the Western Cape, 2023)Concerns regarding the prevalence of chemicals from medicines and personal care goods, such as cosmetics, in streams and rivers have grown in recent years. Water quality experts and environmentalists are becoming increasingly ... -
Geochemical and petrographic evidence for the vredefort proximal impact ejecta in the Northern Cape, South Africa
(University of the Western Cape, 2022)The advancement of the understanding of hypervelocity impacts lies in discovering impact structures and both proximal and distal impact ejecta. This study uses petrographic and geochemical techniques to investigate the ... -
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 ... -
The chemical groundwater characteristics of the Sutherland area, Northern Cape
(University of the Western Cape, 1998)The objectives of the project were to establish, identify, interpret and map the chemical groundwater composition of the area surrounding the town of sutherland' Processes that govern the groundwater chemistry of the area ... -
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 ... -
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 ... -
An approach to acquifer test pumping in fractured crystalline aquifers with a case study in Namaqualand
(University of the Western Cape, 2002)Water resources in South Africa are being stressed. Due to this concern more emphasis should be placed on determining where we can improve our existing methods for the calculation of sustainable yield. Current approaches ... -
An approach to groundwater targeting in the Springbok region, Central Namaqualand, Northern Cape Province, South Africa
(University of the Western Cape, 2003)Namaqualand is a semi-arid region where water is not only a necessity and basic need but also very much a luxury. As a consequence, various studies were undertaken to find water sources, whether surface or groundwater, (by ... -
Groundwater quality monitoring : An approach to groundwater resource quality protection
(University of the Western Cape, 2002)Resource protection is considered by the National Water Act (Act No. 36, 1998) of South Africa as one of the methods that can lead to resource management. Furthermore, the Water Services Act (Act No. 108, 1997) regards ... -
A decision-making framework for groundwater management in arid zones (with a case study in Namaqualand).
(University of the Western Cape, 2004)The main aim of the work on which this thesis is based was to develop a framework for sustainable management of groundwater resources in arid zones with emphasis on Namaqualand in the north western region of South Africa. ... -
Rapid geomorphological change in an urban estuary: a case study of the Eerste River, Cape Town, South Africa.
(University of the Western Cape, 2002)The Eerste River estuary is one of eleven estuaries draining into False Bay. lt is an urban river system and has therefore been subjected to human interference, which has resulted in degradation. This study focuses on ... -
