Application of enviromental and hydrochemical analysis to characterize flow dynamics in the Sakumo Wetland, Ghana
Laar, Cynthia (University of the Western Cape, 2018)This research focused on understanding the current hydrogeology of the Sakumo wetland by developing a conceptual flow model and simulating the groundwater flow system. The purpose of the model is to assist in understanding ... -
Assessment of groundwater management for domestic use from IWRM perspective in upper Limphasa river catchment, Malawi
Kanyerere, T. (University of the Western Cape, 2012)The research problem for this study is the limited and unsuccessful implementation of the IWRM concept. This thesis has argued that comprehensive assessment of physical and socioeconomic conditions is essential to provide ... -
Assessment of managed aquifer recharge using GIS based modeling approach in West Coast, South Africa
Zhang, Heng (University of the Western Cape, 2019)Due to climate change, rapid urbanization, and population expansion, the water demand and supply is showing increasing fluctuations, especially in the arid or semi-arid regions. One of the most important water resource ... -
Assessment of sustainable groundwater utilization with case studies from semi-arid Namibia
Sarma, Diganta (University of the Western Cape, 2016)The thesis addresses sustainability of groundwater utilization in arid and semiarid regions of Namibia. Recharge in this hydrogeological setting occurs as discrete events to aquifers that are bounded in extent. Case studies ... -
Evaluation of groundwater flow theories and aquifer parameters estimation
Xiao, Liang (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 ... -
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
Wang, Zhaoliang (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 ... -

Groundwater Dependence of Aquatic Ecosystems associated with the Table Mountain Group Aquifer
Roets, Wietsche (University of the Western Cape, 2008)Results from this study enables a better understanding of groundwater surface water interactions in the TMG, particularly regarding aquatic ecosystems. It has also highlighted the necessity to do proper impact assessments ... -
Groundwater recharge estimation in Table Mountain Group aquifer systems with a case study of Kammanassie area
Wu, Yong (University of the Western Cape, 2005)The focus of this study was on recharge mechanisms and recharge estimation within the Table Mountain Group area. The study evaluated recharge processes and recharge estimation methods in the Table Mountain Group aquifer systems. -
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. ... -
Groundwater resource evaluation in Table Mountain group aquifer systems
Jia, Haili (University of the Western Cape, 2007)Table Muntain Group has been identified as one of the major Regional Aquifers in South Africa. the vast distribution of it leads to a great diversity in its hydrogeological properties, which influences the dynamics of ... -
Hydraulic properties of the Table Mountain Group (TMG) aquifers
Lin, Lixiang (University of Western Cape, 2008)Research findings in current study provide a new insight into the fractured rock aquifers in the TMG area. Some of the results will have wide implications on the groundwater management and forms a solid basis the further ... -
Hydraulic properties of the Table Mountain group (TMG) aquifers
Lin, Lixiang (University of the Western Cape, 2006)The Table Mountain Group (TMG), located at the southmost cape of African Continent, is one out of three major regional aquifer systems in South Africa, which has a potential of bulk water supply to meet the requirements ... -
Opportunity for implementing reclaimed water for domestic applications in South Africa: institutional engagement and public perceptions
Ndoh Owen, Bella Germaine (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 ... -
