Remote sensing and multispectral imaging of hydrological responses to land use/land cover and climate variability in contrasting agro-ecological systems in Mountainous catchment, Western Cape
(University of the Western Cape, 2022)Water is a fundamental resource and key in the provision of energy, food and health. However, water resources are currently under severe pressure as a consequence of climate change and variability, population growth and ... -
Determining crop coefficients for irrigated fruit tree crops using readily available data sources
(University of the Western Cape, 2022)The climate variability and climate change-induced events experienced worldwide have caused a significant decrease in the rainfall volume. South Africa is considered to be one of the driest countries in the world, as it ... -
Spatial characterization of vegetation diversity with satellite remote sensing in the khakea-bray transboundary aquifer
(University of Western Cape, 2022)There have been increasing calls to monitor Groundwater-Dependent Ecosystems (GDEs) more effectively, since they are biodiversity hotspots that provide several ecosystem services. The accurate monitoring of GDEs is an ... -
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 ... -
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 ... -
The Use of Treated Effluent for Agricultural Irrigation in the Bottelary River Area: Effluent Quality, Farmers Perception and Potential Extent
(University of the Western Cape, 2005)The Bottelary River area is located in a Mediterranean climate region, where the agricultural sector plays an important role. During the dry summer season, there is not enough precipitation to meet the agricultural irrigation ... -
Hydrosalinity Fluxes in a Small Scale Catchment of the Berg River (Western Cape)
(University of the Western Cape, 2008)The occurrence of dryland salinity is widespread throughout semi-arid regions of the world. The sources of salts may be either rock weathering or rain deposition. Clearing of natural scrubland to make way for cultivated ... -
Towards understanding the Groundwater Dependent Ecosystems within the Table Mountain Group Aquifer: A conceptual approach
(University of the Western Cape, 2006)Understanding of Groundwater Dependent Ecosystems (GDEs) and their extent within the Table Mountain Group (TMG) aquifer is poor. To understand the dependence to basic ecological and hydrogeological concepts need explanation. ... -
The Use of Treated Effluent for Agricultural IrrigatiOn!n the Bottelary River Area: Effluent Quality, Farmers Perception and Potential Extent
(University of the Western Cape, 2005)The Bottelary River area is located in a Mediterranean climate region, where the agricultural sector plays an important role. During the dry summer season, there is not enough precipitation to meet the agricultural irrigation ... -
Hydraulic properties of the vadose zone at two typical sites in the Western Cape for the assessment of groundwater vulnerabilitv to pollution
(University of the Western Cape, 2007)Aquifer vulnerability assessment is increasingly becoming a very significant basis in order to fulfil the water demands in South Africa. Knowledge of soil hydraulic properties that consists of the soil water retention and ... -
The effect of particle size separation on the enrichment and recovery of rare earth elements from South African coal fly ash
(University of Western Cape, 2021)There has been increasing interest in finding alternative sources for Rare Earth Elements (REEs) due to their application in green energy and Coal Fly Ash (CFA) has been found to be a viable potential source. Thus ... -
Porosity and Permeability Distribution in the Deep Marine Play of the Central Bredasdorp Basin, Block 9, Offshore South Africa
(University of the Western Cape, 2006)This study describes porosity and permeability distribution in the deep marine play of the central Bredasdorp Basin, Block 9, offshore South Africa using methods that include thin section petrography, X-ray diffraction, ... -
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 ... -
Structural controls on groundwater flow in the Clanwilliam area
(University of the Western Cape, 2005)Deformation of the western part of the Table Mountain Group rocks during the Cape Orogeny created a series of folds and associated fractures. The subsequent continental break-up of Gondwana led to the development of large ... -
Preferential flow modelling in a vadose zone using macro 5.0 - Cape Flats porous sands and Mpumalanga highveld clays case studies
(University of the Western Cape, 2008)Understanding fluid flow and solute transport within the vadose (unsaturated) zone is an essential prerequisite for protection of groundwater from contaminant sources occurring overland. Preferential flow paths in the ... -
The use of constructed wetlands to ameliorate discharge water from coal mines in the Witbank Coalfield
(University of Western Cape, 2021)Mining has a lengthy history in South Africa, and subsequent beneficiation processes have been conducted with little regard for the environment, thus leaving the land with un-rehabilitated abandoned mines. Currently, most ... -
Comparative Study of the Chemostratigraphic and Petrophysical characteristics of Wells A-Al, A-Ll, A-Ul and A-Il in the Orange Basin, South Atlantic Margin, Offshore South Africa.
(University of the Western Cape, 2009)Many hydrocarbon reservoirs are situated in barren sequences that display poor stratigraphic control. Correlation between the wells can become extremely difficult and traditional correlation techniques can prove to be ... -
Multispectral remote sensing of vegetation responses to groundwater variability in the greater floristic region of the Western Cape, South Africa
(University of Western Cape, 2021)Groundwater dependent vegetation (GDV) communities are increasingly threatened by the transformation of the natural environment to different land use/land cover, over-exploitation of groundwater resources and the proliferation ... -
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 ... -
