Acid-base potential characterisation in the Southern highveld coalfield of Mpumalanga
(University of the Free State, 2017-07)Pyrite, iron disulphide is the most common mineral in the metal sulphite and coal deposit. The oxidation of Pyrite and other metal-sulphide minerals by oxygen has a large environmental impact and plays a key role in Acid ... -
Application of artificial neural networks in the field of geohydrology
(University of the Free State, 2009-03)English: Groundwater has been identified as a viable alternative for future freshwater production in South Africa. The management thereof is steadily gaining more recognition from governmental institutions. A significant ... -
Application of the Mixing Cell Model to the quantification of groundwater – surface water interaction
(University of the Free State, 2013-07)English: The significance of a reliable groundwater resource assessment is of growing importance as water resources are stretched to accommodate the growing population. An essential component of a groundwater resource ... -
Aquaponics as a productive rehabilitation alternative in Mpumalanga Highveld coalfields
(University of the Free State, 2016-03-11)The Mpumalanga Highveld Region is commonly known for its coal mining activities, especially surface mines. South Africa is still reliant on coal as its main energy source. A dilemma identified is that most of the coal ... -
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 ... -
Assessment of groundwater resource in the Tsineng area, Northern Cape: a geophysical survey perspective
(University of the Free State, 2016-07)English: In this study the groundwater resource the in Tsineng area, Northern Cape was assessed in terms of the volumes of water that may be sustainably abstracted from the aquifer system, and the quality of the available ... -
Assessment of the groundwater potential of the Middel Kop/Appleby aquifer, Stella District, Northwest Region
(University of the Free State, 2001-08)English: The importance of groundwater is strongly reflected in the new South African water policy and legislation. All water resources, including groundwater, are now seen as an indivisible asset, with the National ... -
Baseline study of Kendal Power Station
(University of the Free State, 2011-05)Abstract not available -
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 ... -
Characterisation of the dolomitic aquifer in the Copperbelt Province, Northern Zambia
(University of the Free State, 2005-02)English: External factors that influence the aquifer characteristics of, and sustainable yield from, the dolomitic aquifer include topography, rainfall, surface drainage, evapotranspiration, plant growth, geology, and ... -
Comparing model calculated groundwater volumes with alternative methods in a mining enviroment
(University of the Free State, 2012-09)English: A new opencast coal mining operation is proposed in the Belfast region in Mpumalanga, South Africa. This proposed operation is the study site that was investigated in this thesis. The Belfast opencast operation ... -
Composition and performance of multi-layer liner systems to inhibit contaminant transport in a fly-ash dump
(University of the Free State, 2013-07)English: The engineering properties of a South African class F fly ash were studied as a potential base liner for a dry coal ash dump. In order to increase the unconfined compression strength, lime and gypsum were added ... -
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 ... -
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 ... -
Decant of sigma colliery
(University of the Free State, 2013-06)English: This study of Sigma Colliery was intended: • To determine the water quality of each aquifer associated with the mining area. • To determine the overall electrical conductivity profile of the mine to aid in the ... -
A decision support system to assess climate change impacts on rural communities
(University of the Free State, 2016-01)English: Climate change is likely to affect the way in which people live. Natural resources such as groundwater, surface water and wood form a vital component of the livelihood in rural communities and are used extensively ... -
