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 ... -
Assessing the effect of the Kars Wetland on flow attenuation in the Cape Agulhas, South Africa
Hans, Damian Trevor (University of the Western Cape, 2019)The Kars has a well-defined channel along the 62 km stretch from its sources in the Bredasdorp Mountains. After entering the Agulhas plain which has a very low gradient, this river changes into a triangular shaped wetland. ... -
Assessment of the contributions of water allocation reforms to achieving equitable access to water by smallholder emerging farmers in the Breede-Gouritz catchment management agency
Mnyaka, Sinazo (University of the Western Cape, 2018)The National Water Act of (1998) of South Africa has a goal of achieving equitable access to water resources, as well as achieving environmental sustainability and efficient use of water. Consequently, water resources ... -
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 the river flow contributions of tributaries and the effects of floodplain wetlands on spatio-temporal variations of river flows in the Nuwejaars river catchment, Cape Agulhas
Mehl, Daniel James Gustav (University of the Western Cape, 2019)Improved knowledge is required on the quantity and source of water resources, particularly evident during periods of drought currently being faced in South Africa. There is inadequate knowledge with regards to the flood ... -
Assessment of the water quality and quantity of the upper Liesbeek River dominated by Cannon Spring discharges: Ecological considerations for the Cannon Spring developmen
Magutywa, Sizeka Felicia (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 ... -
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 ... -
Delineation of groundwater protection zone in a fractured rock aquifer setting: A case study of Rawsonville
Dustay, Shuaib (University of Western Cape, 2020)The Department of Water and Sanitation (DWS) is considering the implementation of an Aquifer Protection Strategy to protect the country’s critical groundwater resources. This study will assist in filling the knowledge gap ... -
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 ... -
The effects of water transfer from Swakoppoort and Omatako Dams on the water quality of Von Bach Dam, Namibia
Sirunda, Johannes Jaime (University of the Western Cape, 2011)In the Otjozondjupa Region, Namibia, water is transferred from Swakoppoort and Omatako Dams into Von Bach Dam to limit evaporation losses and bring water closer to the purification plant. There is a gap in the knowledge ... -
Flood alleviation and restoration on the Lourens river, Somerset west, South Africa
Campher, Dirk Jacobus Martins (University of Western Cape, 2021)Somerset West and Strand in the Western Cape, South Africa, were developed on the Lourens River floodplain. This hardened the catchment and reduced the capacity of the river to transport and store floodwaters. The result ... -
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. ... -
Identification and estimation of ecologically relevant flow indices for non-perennial rivers, South Africa
Schacht, Bernhard Stuart (University of the Western Cape, 2019)The importance of environmental flows and establishing the balance between hydrological response and ecological functioning of rivers has been globally recognised. Methods for determining environmental flows range from ... -
Investigating the effects of nutrients and chlorophyll concentrations on the water quality of the Nuwejaars River, Cape Agulhas, Western Cape
Khungwayo, Agnes Nolitha (University of Western Cape, 2021)The Nuwejaars River flows into the largest natural freshwater lake in South Africa, Soetendalsvlei, which relies on and interacts with the Nuwejaars River. Therefore, the water quality of the Nuwejaars River plays a role ... -
