Application of multivariate statistics and Geographic Information Systems (GIS) to map groundwater quality in the Beaufort West area, Western Cape, South Africa
(UWC, 2013)Groundwater in arid and semi-arid areas like the Karoo region of South Africa is an important source of domestic, agricultural and industrial source of fresh water. As a scarce resource, it requires extensive quality control ... -
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 river-aquifer interaction for sustained water abstraction, Lower Vaal Catchment, South Africa
(University of the Western Cape, 2022)Several methods are available in the literature for the estimations of river-aquifer interactions. However, the selection of which depends on available data, local geographic and topographic conditions, the spatial and ... -
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 ... -
Assessment of the water quality and quantity of the upper Liesbeek River dominated by Cannon Spring discharges: Ecological considerations for the Cannon Spring developmen
(University of Western Cape, 2021)The ecology of spring fed rivers has been under-studied in South Africa. As a result, little is known or documented on the effects of seasonal variation of flows on the species diversity, distribution and abundance of ... -
A comparison of SAAS and chemical monitoring of the rivers of the Lesotho Highlands Water Project
(University of the Western Cape, 2004)The Lesotho Highlands Development Authority routinely uses the South African Scoring System version 4 (SASS4) in conjunction with water chemistry to monitor water quality of rivers in the Lesotho Highlands Water Project ... -
Determining the efficiency of in situ iron remediation (ISIR) technology using ozonation in the Atlantis primary aquifer, Western Cape, South Africa
(University of the Western Cape, 2022)In situ iron remediation (ISIR) applications has become a popular technique for reducing iron and manganese concentrations in boreholes that impose aesthetic and potable issues to groundwater quality and water supply ... -
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 ... -
Effects of catchment management on physical river condition, chemistry, hydrogeomorphology and ecosystem service provision in small coastal rivers of the Western Cape
(University of the Western Cape, 2019)River systems are by nature complex and dynamic systems, which vary in structure and therefore function, and are closely connected to their landscapes. The primary aim of this thesis was to develop a systems operational ... -
The effects of water transfer from Swakoppoort and Omatako Dams on the water quality of Von Bach Dam, Namibia
(University of the Western Cape, 2011)In the Otjozondjupa Region, Namibia, water is transferred from Swakoppoort and Omatako Dams into Von Bach Dam to limit evaporation losses and bring water closer to the purification plant. There is a gap in the knowledge ... -
Geochemical assessment of groundwater quality and suitability for drinking and irrigation purposes in Newcastle, Kwazulu-Natal, South Africa
(University of the Western Cape, 2016)Groundwater is one of the most valuable natural resources on earth and it forms an important part of the total water resources of South Africa. For this reason, this resource should be monitored and controlled on a regular ... -
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 ... -
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 ... -
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 ... -
Investigating the effects of nutrients and chlorophyll concentrations on the water quality of the Nuwejaars River, Cape Agulhas, Western Cape
(University of Western Cape, 2021)The Nuwejaars River flows into the largest natural freshwater lake in South Africa, Soetendalsvlei, which relies on and interacts with the Nuwejaars River. Therefore, the water quality of the Nuwejaars River plays a role ... -
Investigating the impact of effluent from wastewater treatment works on river water quality, Baths River, Caledon, Western Cape, South Africa
(University of Western Cape, 2021)South Africa is facing a problem of many municipal waste water treatment works (WWTW) not working efficiently. The environmental impacts of poorly treated effluents on receiving water bodies have required special attention ... -
Investigating the natural groundwater recharge and discharge processes of the Saldanha Bay aquifer systems along the West Coast of South Africa
(University of the Western Cape, 2022)Saldanha Bay Local Municipality is partially dependent on groundwater as part of its bulk water supply as surface water resources in the area are extremely limited and fully allocated. Due to this, there is lots of ... -
