Managing the impact of irrigation on the Tosca-Molopo groundwater resource
(University of the Free State, 2005-05)From 1990 to 2000 rapid development of irrigation from groundwater resources in dolomite aquifers took place in the Tosca Molopo area. This abstraction lead to water levels declining 10 to 20m regionally and up to 60m ... -
Manual on pumping test analysis in fractured rock aquifers
(University of the Free State, 2000-11)English: With the depletion of surface water resources in South Africa the utilisation of groundwater as the only potable water resource for communities in some rural areas is quickly becoming a reality. Failure of this ... -
Modelling reactive pollutant transport in ground water: the case of two species
(University of the Free State, 2019-06)The locations of a significant number of industrial facilities, landfills and almost all mineral ore bodies are characterised by high in situ stresses and fractures and fissures act as flow paths for fluids underground. ... -
A new method for modeling groundwater flow problems: fractional-stochastic modeling
(University of the Free State, 2019-06)To date, groundwater flow problems are still increasingly becoming a great environmental concern worldwide. This is among some of the reasons that many researchers from various fields of science have focused much of their ... -

The occurrence and evaluation of LNAPLs contamination in urban areas of South Africa
(University of the Free State, 2005-11)Petroleum liquids are a basic building block of our modern lives. Uses include fuels, lubricants, and the raw material for manufactured products. The by-product of these uses has been the inadvertent release of petroleum ... -
Open pit flooding as a post-closure option: a geochemical approach
(University of the Free State, 2014-07-16)Australasian, European, Canadian and American geo-environmental specialists have long been involved with pit lake studies in the physical processes and dynamics as well as the geochemical aspects of these mitigation methods ... -
Open pit flooding as a post-closure option: a geochemical approach
(University of the Free State, 2013-05)English: Australasian, European, Canadian and American geo-environmental specialists have long been involved with pit lake studies in the physical processes and dynamics as well as the geochemical aspects of these ... -
Quantification of the impact of irrigation on the aquifer underlying the Vaalharts irrigation scheme
(University of the Free State, 2003-11)Abstract not available -
Quantification of the impacts of a domestic waste site on a Karoo aquifer
(University of the Free State, 2008-05)Waste generation is a widespread phenomenon around the world, of which the majority is disposed by landfilling. In landfills, waste constitutes an integral part of the hydrological system, and thus poses a threat to ... -
A quantitative approach in mine water balances and strategic management
(University of the Free State, 2014-04)English: The vital role of water within the mining industry, both as an asset which generates value as well as a shared natural resource requiring responsible stewardship, have long been recognised. Due to extreme climate ... -
Reactive transport modelling of fertilizer waste in a dual porosity aquifer
(University of the Free State, 2011-11-16)English: The fertilizer production facility had a negative impact on the soil, groundwater and surface water environment due to the handling / storage and production activities at the site. Observations and numerical ... -
Reconceptualization of the extended groundwater regime of the Vaalputs radioactive waste site
(University of the Free State, 2015-08)Vaalputs Radioactive Waste Site is the only nuclear waste facility in South Africa that stores Low- and Intermediate Level Radioactive Waste. Disposal of waste is carried out under the authorization granted by the National ... -
The relation between South African geology and geohydrology

Site characterization and risk assessment of organic groundwater contaminants in South Africa
(University of the Free State, 2004-11)English: South Africa has only recently realized that organic groundwater contamination occurs in this country and that it can have a serious effect on the groundwater quality. The Water Research Commission (WRC) recently ... -
Stochastic groundwater flow models in confined and leaky aquifers
(University of the Free State, 2019-06)This dissertation proposes an application of stochastic modeling of groundwater flow in confined and leaky aquifers. We are estimating that aquifer parameters such as transmissivity, storativity and leakage factor vary, ...
