Site characterisation of LNAPL-contaminated fractured-rock aquifer
(University of the Free State, 2009-08)Site characterisation aims to obtain fundamental data needed to describe the subsurface flow pathways and distribution of contaminants. The study describes the application of various geohydrological techniques as complimentary ... -
Site characterisation for LNAPLs investigation using electrical resistivity tomography (ERT) survey
(University of the Free State, 2009-11) -
Characterisation and management of a LNAPL pollution site along the coastal regions of South Africa
(University of the Free State, 2009-11)English: The project site experienced LNAPL spills in the recent past. In the characterisation of the site it was necessary to investigate the physical properties of the vadose and saturated zones. It was found that ... -
The influence of the irrigation on groundwater at the Vaalharts Irrigation Scheme
(University of the Free State, 2009-11-20)English: Vaalharts Irrigation Scheme is not only the largest in the country it is known as “The Food Basket”. In 1875, Mr Ford, a Government Surveyor got the idea that the Vaalharts area has irrigation scheme possibilities ... -
The groundwater flow regime of the Kombat Aquifer, Namibia
(University of the Free State, 2009-11-27)The Kombat Aquifer, as investigated in this study, comprises the dolomite of the upper and lower Otavi Group, encompassing a radius of about 10 km around Kombat Mine. Groundwater flow controls, structural influence, and ... -
Investigation into the groundwater interaction between a deep coal mine and a deeper lying gold mine
(University of the Free State, 2010-11)After the closure of mines, it is expected that water in the mined-out areas will flow along preferred pathways and accumulate in lower-lying areas (Grobbelaar, 2001). Over time, these man-made voids will fill up with ... -
Decant calculations and groundwater: surface water interaction in an opencast coal mining environment
(University of the Free State, 2010-11)English: Acid mine drainage is by far the most significant long term groundwater quality impact associated with both opencast and underground coal mining, in both a local and international context. The modern day ... -
The impacts of fertilizer manufacturing on groundwater in South Africa
(University of the Free State, 2010-11)English: As a result of the fertilizer industry’s rapid growth, and the increasing global awareness concerning environmental issues, fertilizer production facilities have come under growing pressure to comply with ever ... -
Development of decision-support guidelines for groundwater related vulnerability assessments
(University of the Free State, 2010-11)Climate change is major threat to our world particularly poor countries. Climate change is driven by changes in the atmospheric concentrations of Greenhouse Gases and aerosols. These gases affect the absorption, scattering ... -
Ground water dependence of ecological sites located in the Table Mountain group
(University of the Free State, 2010-11)Abstract not available -
The feasibility of numerical models in LNAPL related ground-water studies
(University of the Free State, 2010-11-25)English: Groundwater contamination as a result of Light Non Aqueous Phase Liquid (LNAPL) releases into the subsurface is a widespread occurrence across South Africa which threatens current and future water resources within ... -
Impact and risk assessment of chromium contaminated groundwater sites in saturated and unsaturated zones
(University of the Free State, 2011)English: A key challenge for chromium related activities, such as in ferrochromium industries, is the disposal of waste containing chromium slag or dust with hexavalent chromium (Cr(VI)). Various investigations have shown ... -
Flow characteristics of groundwater systems: an investigation of hydraulic parameters
(University of the Free State, 2011-05)The Institute for Groundwater Studies (IGS) undertook a groundwater surface water interaction project under the funding of Water Research Commission starting July 2010. The Modder River was identified as an appropriate ... -
Assessing the feasibility of constructing a groundwater contaminant fate and transport model for an LNAPL affected fractured rock aquifer
(University of the Free State, 2011-05)English: Groundwater contamination as a result of Light Non Aqueous Phase Liquid (LNAPL) releases into the subsurface is a widespread occurrence across South Africa which threatens current and future water resources within ... -
Baseline study of Kendal Power Station
(University of the Free State, 2011-05)Abstract not available -
Coupled flow in groundwater systems : the study of bulkflow parameters
(University of the Free State, 2011-08)This study was aimed at studying bulkflow parameters in groundwater systems at littoral zone of the Modder River. In this thesis, all the aspects were synthesised and exemplified by incorporating a multidisciplinary ... -
Groundwater monitoring guidelines for the coal industry
(University of the Free State, 2011-10)Abstract not available -
Design optimisation of hazardous waste disposal facilities through the application of water balance and mass transport modelling
(University of the Free State, 2011-11)Although the country’s legislation emphasizes the importance of waste prevention, recovery and re-use, waste disposal currently forms the basis of waste management within South Africa. Due to the lack of facilities as well ... -
Towards a conceptual hydrogeological model of the Chimiwungo ore body, Lumwana Mine, Northwestern Zambia
(University of the Free State, 2011-11)A deep and clear understanding of the hydrogeology of an area is paramount in any dewatering project. The development of a detailed conceptual hydrogeological model goes a long way in creating an appreciation of the ... -
The influence of flooding on underground coal mines
(University of the Free State, 2011-11)English: The purpose of the study is to investigate the influence of flooding on underground coal mines. Two case studies were investigated the shallow underground Klibarchan coal mine and the deep underground Usutu mine. ...
