A comparative analysis of long-term variations of temperature and rainfall in rural and urban areas, and their effects on the estimation of design storms in Kenya
Gachahi, Lydiah Wangechi (University of the Western Cape, 2016)My Thesis aimed at expanding the current knowledge on how variations of temperature characteristics including the possible existence of urban heat islands (UHI) over urban areas of Kenya could be influencing rainfall ... -
An analysis of sustainability of communally-managed rural water supply systems in Zimbabwe
Kativhu, Tendai (University of the Western Cape, 2016)Sustainability of rural water supply systems is a major development challenge in most developing countries including Zimbabwe. This thesis aimed to analyse the sustainability of communally managed rural water supply systems ... -
Assessing land use-land cover changes and their effects on the hydrological responses within the Nyangores River Catchment, Kenya
Ndungo, Margaret Njoki (University of Western Cape, 2021)This thesis aimed at contributing knowledge on how the widespread changes in land use/cover resulting from increasing human population and their associated activities, are influencing hydrological responses in a sub-humid ... -
An assessment of the influence of water allocation on sustainable water resources management: A case study of the Nyando river basin, Kenya
Sungu, Ronald O. (University of the Western Cape, 2018)Water problems prevalent in the Nyando River Basin are due to an ineffective water allocation system and lack of adequate conditions for implementation of sustainable integrated water resources management (IWRM) strategies. ... -
An assessment of water use by riparian and non-riparian invasive alien plants and the effects on water resources at the catchment scale
Mkunyana, Yonela Princess (University of the Western Cape, 2023)The diversity and increasing extent of invasive alien plants (IAPs) are currently a global ecological and economic problem, especially in semi-arid regions. The introduction of IAPs worsens the strain in South Africa’s ... -
Characterization of flowpaths to improve the prediction of vegetation impacts on hydrological processes in semi-arid mountainous catchments of the Cape Fold Belt
Jumbi, Faith Tatenda (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 ... -
Effects of land-cover - land-use on water quality within the kuils - Eerste River Catchment
Chingombe, Wisemen (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 ... -
Groundwater resource evaluation and protection in the Cape Flats, South Africa
Adelana, Segun Michael Adegboyega (University of the Western Cape, 2010)The analysis of geologic, hydrologic and hydrogeologic data interpreted to give the characteristics of the Cape Flats aquifer showed the quality of groundwater from the aquifer is suitable for development as a water resource. ... -
The partitioning of evapotranspiration in apple orchards from planting until full-bearing age and implications for water resources management
Ntshidi, Zanele (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 ... -
Spatial and temporal variation of inundation in the Okavango Delta, Botswana; with special reference to areas used for flood recession cultivation
Dikgola, Kobamelo (University of the Western Cape, 2015)The Okavango Delta is recognized as one of the famous inland wetlands and its sustainable use is important for socio-economic development of Botswana. The Okavango delta comprises permanent swamps, seasonal swamps, and ... -
Spatial and temporal variations of inundation and their influence on ecosystem services from a shallow coastal lake. A case study of Soetendalsvlei in the Nuwejaars catchment, South Africa
Carolissen, Mandy (University of Western Cape, 2021)Enhancing our understanding of wetland properties and the ecosystem services provided by wetlands within a dynamic landscape, is fundamental to ensuring appropriate management strategies for enhanced biodiversity and ... -
Streamflow generating mechanisms in a mountainous Jonkershoek catchment, South Africa
Mokua, Retang Anna Lapalemabu (University of the Western Cape, 2022)The Jonkershoek valley catchment in a mountain region that forms the headwaters of the Eerste River, which contributes water to the Cape Winelands District Municipality and parts of the City of Cape Town in the Western ...
