Understanding spatial patterns of dispersal and deposition of fine sediment and adsorbed phosphates in the Wiesdrift Wetland on the Nuwejaars River, Cape Agulhas
(University of the Western Cape, 2021)River catchments in agricultural areas are strongly influenced by runoff from cultivated or grazed fields, and nutrient loading of these fields can result in large quantities of nitrates and phosphates being transported ... -
Understanding Striga occurrence and risk under changing climatic conditions across different agroecological farming systems at local and regional scales122
(University of Western Cape, 2020)The invasion by Striga in most cereal crop fields in Africa has posed an acute threat to food security and socioeconomic integrity. Consequently, numerous technological and research developments have been made to minimize ... -
The use of chemostratigraphy and geochemical vectoring as an exploration tool for platinum group metals in the Platreef, Bushveld Igneous Complex, South Africa : a case study on the Tweefontein and Sandsloot farms
(University of the Western Cape, 2015)The Platreef is known for its complexity and its heterogeneous lithologies, coupled with an unpredictable PGE and BMS mineralisation. The motivation behind this study was to aid mining geologists in targeting mineralisation ... -
The use of chemostratigraphy and geochemical vectoring as an exploration tool for platinum group metals in the Platreef, Bushveld Igneous Complex, South Africa: a case study on the sandsloot & overysel farms
(University of the Western Cape, 2014)The paucity of geochemical criteria for stratigraphic correlations and defining the styles of mineralisation pose serious problems in locating PGE-rich zones in the Platreef. This study is therefore aimed at identifying ... -
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 ... -
The use of derivative analysis and aquifer parameter estimation to refine a conceptual model: A case study approach, Western Cape, South Africa
(University of Western Cape, 2021)Hydrogeological characterization of an aquifer system is a first step to determine groundwater quantity, yield potential, socio-economic value, storage capacity and aquifer transmissivity properties of an aquifer as a water ... -
The use of GIS, statistical and risk assessment tools to evaluate aquifer vulnerability to potential contaminants
(The University of the Western Cape, 2017)An aquifer is a body of permeable rock which can contain or transmit groundwater. It is a low cost water supply for domestic and agricultural use. Routine monitoring of aquifers is important to prevent contamination and ... -
The use of remote sensing data for assessing water quality in wetlands within the Limpopo River Basin
(University of the Western Cape, 2021)Wetlands are unique ecosystems that are acknowledged among the world’s most productive and valuable ecosystems. They are recognized as being essential to sustainable development and human welfare due to their unique ... -

The use of remote sensing data to monitor pools along non-perennial rivers in the Western Cape, South Africa.
(University of the Western Cape, 2019)The lack of monitoring of non-perennial rivers is a major problem for water resources management, despite their significance in satisfying agricultural, economic and recreational needs. Pools in non-perennial rivers are ... -
The use of remote sensing for soil moisture estimation using downscaling and soil water balance modelling in Malmesbury and the Riebeek Valley
(University of the Western Cape, 2014)Soil moisture forms an integral part of the hydrological cycle and exerts considerable influence on hydrological processes at or near the earth’s surface. Knowledge of soil moisture is important for planning and decision-making ... -
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 ... -
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 ... -

The use of well log data in the creation of 3D geological maps
(University of the Western Cape, 2021)Three-dimensional (3D) graphic representations of geographic environments have become commonplace in a range of elds. These representations are often an attempt to represent both geographic forms, as well as the ... -
Using citizen science in monitoring groundwater levels to improve local groundwater governance, West coast, South Africa
(University of the Western Cape, 2019)Monitoring of groundwater levels provides a basis for assessing the availability of water in aquifers, thereby informing the decisions on abstraction and uses of such water for various purposes. It provides an understanding ... -
Using coupled atmospheric-unsaturated zone model to quantify groundwater recharge to the Table Mountain Group Aquifer system, George, South Africa
(University of the Western Cape, 2019)The current study aimed at providing groundwater recharge estimates in a fractured rock aquifer environment that is occupied by pine plantation and indigenous forests in order to improve the understanding of the effect of ... -
Using geostatistical-hydrogeological approach to develop groundwater monitoring system in South Western Karoo, South Africa
(University of the Western Cape, 2017)Groundwater in the South Western Karoo plays a vital role in the overall water supply in the region. However, this resource is vulnerable to impacts from anthropogenic and natural activities. Mitigating the impacts on ... -
Using hydrogeochemistry and geophysical techniques to determine the extent of connectivity between Langerban road and Elandsfontein aquifer system, West Coast, South Africa
