The influence of canopy cover and cultivar on rates of water use in apple orchards in the Western Cape Province, South Africa
(University of the Western Cape, 2020)Water availability and climate related issues are some of the greatest crop production risks to irrigated agriculture in arid regions. In South Africa, for example, the increasing frequency and severity of droughts related ... -
Integrated approach to solving reservoir problems and evaluations using sequence stratigraphy, geological structures and diagenesis in Orange Basin, South Africa
(University of the Western Cape, 2010)Sandstone and shale samples were selected within the systems tracts for laboratory analyses. The sidewall and core samples were subjected to petrographic thin section analysis, mineralogical analyses which include x-ray ... -
Integrated approach to solving reservoir problems and evaluations using Sequence Stratigraphy, Geological Structures and Diagenesis in Orange Basin, South Africa"
(University of the Western Cape, 2010)The use of integrated approach to evaluate reservoir rock quality and source rock potential is becoming increasingly important in petroleum geology. This approach was employed to unravel the reason for variable reservoir ... -
An integrated study of the early cretaceous (Valanginian) reservoir from the Gamtoos Basin, offshore South Africa with special reference to seismic cacies, formation evaluation and static reservoir modeling
(University of the Western Cape, 2019)Integrated approaches in the study of petroleum exploration are increasingly becoming significant in recent times and have yielded much better result as oil exploration is a combination of different related topics. The ... -

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 ... -
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 ... -
NON-INVASIVE CHARACTERIZATION OF UNSATURATED ZONE TRANSPORT IN DRY COAL ASH DUMPS: A CASE STUDY OF TUTUKA, SOUTH AFRICA
(University of the Western Cape, 2013)The management of the large volumes of solid wastes produced as coal combustion residue is of particular concern due to the presence of leachable metals and salts which may constitute a long term environmental risk and ... -
Novel approach of using Hydrogeochemistry, Hydrogeologic and Hydrostratigraphic techniques in evaluating coastal aquifers in Heuningnes catchment, South Africa
(University of the Western Cape, 2019)The increasing population in search for better social and economic development in coastal areas puts groundwater resources under pressure because of the high fresh water demand for domestic and agriculture use. Seawater ... -
Opportunity for implementing reclaimed water for domestic applications in South Africa: institutional engagement and public perceptions
(University of the Western Cape, 2017)Water scarcity which impacts negatively on humans, as well as on the natural environment, is a real problem facing developed and developing countries. The reuse of wastewater is a critical component of the effective and ... -
The partitioning of evapotranspiration in apple orchards from planting until full-bearing age and implications for water resources management
(University of Western Cape, 2021)Orchard evapotranspiration (ET) is a complex flux which has been the subject of many studies. It often includes transpiration from the trees, cover crops and weeds, evaporation from the soil, mulches, and other orchard ... -
