Groundwater Dependence of Aquatic Ecosystems associated with the Table Mountain Group Aquifer
(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 management model for the Spitskop area in South Africa
(University of the Western Cape, 2014)The thesis investigates the potential of the Rietfontein and Spitskop aquifer to meet a demand of 1000 m3/d (12 Lis) as an alternative water resource for the Rietfontein and Spitskop Community. Increasing demand for clean ... -
Groundwater occurrence of Table Mountain area in Cape Town, South Africa
(University of the Western Cape, 2009)Groundwater is an important water resource to be used to supplement the water demand for the City of Cape Town for present and future generations. Understanding the groundwater occurrence of the Table Mountain area is very ... -
Groundwater quality monitoring : An approach to groundwater resource quality protection
(University of the Western Cape, 2002)Resource protection is considered by the National Water Act (Act No. 36, 1998) of South Africa as one of the methods that can lead to resource management. Furthermore, the Water Services Act (Act No. 108, 1997) regards ... -
Groundwater recharge estimation in Table Mountain Group aquifer systems with a case study of Kammanassie area
(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
(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
(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 ... -
Groupoids of homogeneous factorisations of graphs
(University of the Western Cape, 2009)This thesis is a study on the confluence of algebraic structures and graph theory. Its aim is to consider groupoids from factorisations of complete graphs. We are especially interested in the cases where the factors are ... -
Growth and characterization of FeSi nanowires by chemical vapor deposition for gas sensing applications
(University of the Western Cape, 2014)FeSi nanowires were synthesized via a chemical vapor deposition method. Anhydrous FeCl3 powder in this case served as the Fe source and was evaporated at a temperature of 1100oC to interact with silicon substrates which ... -
