Prefeasibility study for managed aquifer recharge within the Greater Kruger National Park, Limpopo province, South Africa
(University of the Free State, 2022-02)The Greater Kruger National Park (GKNP) is located in South Africa, which is a relatively dry country and among the 20 most water-scarce countries in the world. Two study sites for a prefeasibility study are situated along ... -
Evaluation of a training manual for groundwater resource management and groundwater governance for municipalities in South Africa
(University of the Free State, 2021-11)Groundwater knowledge is crucial in water scarce countries like South Africa. The management of groundwater resources are often neglected, and there is a lack of proper knowledge in groundwater as a discipline. It is vital ... -
Characterisation of the deep aquifers of South Africa - the Karoo Supergroup and Table Mountain Group
(University of the Free State, 2019-06)Abstract not available -
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, ... -
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 ... -
Investigation of hydrogeochemical processes and groundwater quality in the Chókwè district, Mozambique
(University of the Free State, 2016-06)Groundwater has been recognised in Sub-Saharan countries as the main source of potable water in rural areas. In semi-arid regions, the climatic and anthropogenic factors both significantly affect groundwater quality. The ... -
Evaluation of management options for intermine flow and associated impacts in the Central Witbank Coalfield
(University of the Free State, 2003-07)English: Research into the identification, quantification and impact assessment of the intermine flow on the groundwater and surface water quality of the Witbank and Highveld coalfields was undertaken as part of broader ... -
Site characterisation of LNAPL-contaminated fractured-rock aquifer
(University of the Free State, 2009-08)English: 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 ... -
An investigation into the temporal and spatial mobility of leachate production in a fly-ash dam
(University of the Free State, 2013-07) -
Evolution of fluid electrical conductivity (FEC) profiles associated with a contaminant plume in a horizontal single-plane fractured rock aquifer system
(University of the Free State, 2017-07)Fluid electrical conductivity (FEC) profiling is a simple and efficient technique used to determine properties such as flow rate, salinity and hydraulic characteristics such as transmissivity. The method is also commonly ... -
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 ... -
The development of a pre-mining groundwater monitoring network for open pit mines in South Africa
(University of the Free State, 2017-05)English: After the discovery of minerals mining formed the backbone of the South African economy for more than a century. The contribution that mining had on the economy is probably best reflected when the country’s ... -
A feasibility study of in-situ iron removal in the atlantis primary aquifer, Western Cape province, South Africa
(University of the Free State, 2014-06)English: The sustainability of many wellfield is threatened due to elevated iron (Fe2+) and manganese (MN2+) concentrations in groundwater. Their presence causes aesthetic and potability problems but the greatest concern ... -

Geohydrological characteristics of the Msikaba, Dwyka and Ecca groups in the Lisikisiki area, Eastern Cape
(University of the Free State, 2007-11)English: The study focused on the three major geological units, namely the Natal Group Sandstone (NGS or also called Msikaba Sandstone), the Dwyka Formation and the Ecca Group and was aimed at investigation the geohydrological ... -
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 description of physico-chemical processes in coal mine spoils and associated production of acid mine drainage
(University of the Free State, 2007-05)English: In the first part of this study the typical physico-chemical processes involved in Acid Mine Drainage (AMD) generation were discussed. This included a detailed description of mineralogical reactions, oxygen migration ... -
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 ...
