Investigating subsurface heterogeneities and its impact on the variation in interval velocities : implications to velocity modelling in the Bredasdorp basin
(University of the Western Cape, 2015)Velocity modelling forms an integral part of the seismic interpretation process initially completed in two-way time. In order for a representative depth conversion, it is obligatory to construct a velocity model that serves ... -
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 ... -
Investigating the role of groundwater - surface water connectivity in supporting non-perennial river systems, Sandveld, Western Cape, South Africa
(University of the Western Cape, 2021)Non-perennial rivers are characterised by a discontinuous and variable hydrological flow regime which may retreat to form isolated pools along the watercourse during prolonged dry periods. The resulting spatio-temporal ... -
Investigation of deep groundwater flow systems in the Main Karoo Basin of South Africa
(University of the Western Cape, 2017)The improvement in hydraulic fracturing techniques resulted in the exploitation of natural gas associated with low-permeability of organic-rich shale formations in the United States. South Africa has prospective shale gas ... -
Investigation of the acoustic impedance variations of the upper shallow marine sandstone reservoirs in the Bredasdorp basin, offshore South Africa
(University of the Western Cape, 2019)Investigation of the acoustic impedance variations in the upper shallow marine sandstone reservoirs was extensively studied from 10 selected wells, namely: F-O1, F-O2, E-M4, E-CN1, E-G1, E-W1, F-A10, F-A11, F-A13, and F-L1 ... -
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 ... -
Land use practices and their impact on the water quality of the Upper Kuils River (Western Cape Province, South Africa)
(University of Western Cape, 2014)The water quality in many Cape Town Rivers and streams is a major challenge. Kuils River is subject to multiple land use impacts from upstream to downstream because of rapid urbanization in its catchment area. The main ... -
The lithogeochemical characterization of the Hondekloof nickel mineralization, Kliprand area, Garies Terrane, Namaqualand, South Africa
(University of the Western Cape, 2015)A magmatic Ni-Cu (±Co-Zn) sulphide deposit, named the Hondekloof prospect, is present in the Kliprand area at the border between the Northern Cape and Western Cape Provinces of South Africa. The deposit occurs in the central ... -
Magmatic-petrogenetic & structural relationships of the peninsula granite of the Cape Granite Suite (CGS) with the Malmesbury group, sea point contact, Saldania belt, South Africa
(University of Western Cape, 2021)The Sea Point contact, Cape Town, South Africa, exposes the contact between the Neoproterozoic Malmesbury Group metasedimentary rocks of the Pan-African Saldania belt and the intrusive S-type Peninsula Granite of the ... -
Magmatic-petrogenetic & structural relationships of the Peninsula Granite of the Cape Granite Suite (CGS) with the Malmesbury Group, Sea Point contact, Saldania Belt, South Africa
(University of the Western Cape, 2020)The Sea Point contact, Cape Town, South Africa, exposes the contact between the Neoproterozoic Malmesbury Group metasedimentary rocks of the Pan-African Saldania belt and the intrusive S-type Peninsula Granite of the ... -
Mapping Break-Back Thrust Sequence Developments of the Orange Basin (offshore South Africa)
(University of the Western Cape, 2017)In the present study thrust sequence developments in the sediments below the deep-waters of the Orange Basin are mapped. Four seismic sections are interpreted from four different locations of the study area. The interpreted ... -
Measurement and modelling of catchment erosion dynamics under different land cover types, Jonkershoek Catchment, Western Cape
(University of the Western Cape, 2020)Several attempts have been made to assess the impact of post-fire soil erosion; however, erosion occurs as a result of the complex interplay between many factors, such as climate, land cover, soil and topography, making ... -
Modelling of nonpoint source pollution in the Kuils River catchment, Western Cape - South Africa
(University of the Western Cape, 2008)The Kuils River Catchment is an urban river catchment that forms part of the larger Kuils-Eerste River system draining the eastern half of the Cape Metropolitan Authority area and Stellenbosch Municipality. Rapid urbanisation ... -
Modelling the behaviour and fate of priority pesticides in South Africa
(University of the Western Cape, 2005)The use of pesticides poses a serious threat to the limited water resources of South Africa. The amounts which are not taken up by crop plants, are often washed away by runoff into surface waters, or leached through the ... -
The morphodynamic characteristics of erosional headcuts in Palmiet (Prionium serratum) wetlands
(University of the Western Cape, 2018)Gully erosion and headcut migration has been at the crux of wetland degradation in South Africa. The resulting erosion and draining effect has seen more than 50% of wetlands in the country degraded. This study investigated ... -
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 ... -
