Characterization of flowpaths to improve the prediction of vegetation impacts on hydrological processes in semi-arid mountainous catchments of the Cape Fold Belt
(University of Western Cape, 2021)Mountainous areas are important water sources in many landscapes. An understanding of how mountainous catchments function is important particularly in semi-arid areas, where water shortages are prevalent. In addition to ... -
Citizen participation and water services delivery in Khayelitsha, Cape Town
(University of the Western Cape, 2011)This study analyses the relationship between the manner of citizens’ engagement with the state and the level of service delivery they experience in their everyday lives, as residents of Khayelitsha. The phenomena of so-called ... -
Constraints on the genesis of the Sandamap gold prospect, Namibia: fluid inclusion, geochronology and stable isotope studies
(University of the Western Cape, 2020)The Sandamap gold prospect is a metaturbidite shear zone-hosted gold mineralization located in the Neoproterozoic Damara Orogen 30 km northwest of the town of Usakos in Namibia with an estimated gold content of 240 000 t ... -
A decision-making framework for groundwater management in arid zones (with a case study in Namaqualand).
(University of the Western Cape, 2004)The main aim of the work on which this thesis is based was to develop a framework for sustainable management of groundwater resources in arid zones with emphasis on Namaqualand in the north western region of South Africa. ... -
Developing a citizen science framework for water resources protection to facilitate operationalization of resource directed measures at catchment level, South Africa
(University of Western Cape, 2021)Maintenance of water resources protection practice for water availability, uninterrupted water utilization, and for ecosystem integrity is critical for sustainable achievement of resource security for all. Therefore, ... -

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 ... -
Effects of land-cover - land-use on water quality within the kuils - Eerste River Catchment
(University of Western Cape, 2012)The most significant human impacts on the hydrological system are due to land-use change. The conversion of land to agricultural, mining, industrial, or residential uses significantly alters the hydrological characteristics ... -
Evaluation of groundwater flow theories and aquifer parameters estimation
(University of the Western Cape, 2014)This thesis deals with some fundamental aspects of groundwater models. Deterministic mathematical models of groundwater are usually used to simulate flow and transport processes in aquifer systems by means of partial ... -
Geochemical and mineralogical evaluation of toxic contaminants mobility in weathered coal fly ash: as a case study, Tutuka dump site, South Africa
(University of the Western Cape, 2011)The management and disposal of huge volumes of coal combustion by products such as fly ash has constituted a major challenge to the environment. In most cases due to the inadequate alternative use of coal fly ash, the ... -
Geochemical evaluation of source rock potential and characterization of hydrocarbon occurrences in the Eastern Dahomey Basin, Nigeria
(University of Western Cape, 2020)Nigeria is endowed with significant oil sand and heavy oil reserves. These reserves are found within the Cretaceous Afowo Formation in the Eastern Dahomey Basin. The petroleum systems and quality of these reserves are ... -
Geochemical, Sedimentological and Mineralogical Study of Sediments along Coastal Areas of Abu Dhabi, United Arab Emirates (UAE): Implications for Provenance, Depositional Environment, Heavy Minerals and Radiogenic Elements Contamination
(University of the Western Cape, 2017)This study describes sedimentological, geochemical and mineralogical results of the beach sediments of Abu Dhabi in the United Arab Emirates in order to understand the provenance, depositional environment and the level of ... -
Geological and hydrgeological characteristics of acid mine drainage from an abandoned coal mine: A case study of Shandi coal mine in Niangziguan spring catchment, Shanxi
(University of Western Cape, 2022)As Shanxi Province is rich in coal resources, the output of raw coal approximately accounts for one quarter of China's production. It is one of the most important energy and heavy chemical bases and plays a significant ... -
GIS and remote sensing-based integrated modelling of climate and land use change impacts on groundwater quality: Cape Flats Aquifer, South Africa
(University of Western Cape, 2021)The need to ensure groundwater security is vital, particularly in urban areas. Assessing the impact of land use and climate variables on groundwater quality can help improve sustainable management. The vulnerability mapping ... -
Greywater reuse - An assessment of health and nutritional quality of home gardens produce in rural South Africa
(University of Western Cape, 2021)The majority of rural communities in sub-Saharan Africa are predominantly poor and depend largely on small-scale subsistence farming. To date, various farming mechanisms (e.g. organic farming, crop rotation, agroforestry ... -
Groundwater assessment and sustainable management of the coastal alluvial aquifers in Namib Desert, Namibia: Omdel Aquifer as case study
(University of Western Cape, 2020)The study addressed the groundwater assessment and sustainable management of the coastal alluvial aquifers in Namib Desert, the Omaruru River Delta Aquifer (Omdel Aquifer) was used as a case study. Sustainable utilization ... -
