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 ... -
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 ... -
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 ... -
Designing a dewatering plan for the Ruashi mine in the Democratic Republic of Congo
(University of the Free State, 2013-09)This dissertation describes the results of field based investigations on groundwater flow at Ruashi Mine located in Katanga Province of Democratic Republic of Congo (DRC). The core objectives of the study were to simulate ... -
Development of a groundwater recharge model
(University of the Free State, 2017-01)English: Existing groundwater recharge estimation methods appear to mainly generate site specific groundwater recharge estimates. These methods fail to yield reliable recharge estimates on a regional scale. This is due ... -
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 ... -
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 ... -
Development of guidelines for the management of groundwater in and around rehabilitated coal discard facilities
(University of the Free State, 2017-05)No abstract -
Enviromental impact of point pollution sources
(University of the Free State, 1999-07)English: Due to the importance of groundwater as an alternative for supplementing existing sources of this precious fluid, any study that may help in understanding the complexity of the groundwater environment is an ... -
The environmental impacts of the groundwater on the St. Lucia wetland
(University of the Free State, 2013-04)Abstract not available -
Estimation of the preliminary groundwater reserve using numerical models
(University of the Free State, 2000-06)English: The Water Act requires the determination of the Groundwater Reserve to secure the basic human needs and to protect the environment (aquatic ecosystems in terms of the Act). In other words, it is necessary to ... -
Evaluation of acid-base accounting methods and the prediction of acid-mine drainage in the Middelburg area
(University of the Free State, 2012-02)English: South Africa has several coal mines of which promised economic wealth since the 1700, however the exploitation of this commodity has a negative effect to the environment. Mining operations are a source of Acid ... -

(University of the Free State, 2003-09)This study aimed at assessing the ground water resources potential in Pallisa district, which is found in the eastern part of Uganda. The aims of the investigation can be Iisted as follows: ~ To determine the reliability ... -
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 ... -
An evaluation of the suitability of different electrode arrays for geohydrological studies in Karoo rocks using electrical resistivity tomography
(University of the Free State, 2013-01)The suitability of different electrodes arrays used during electrical resistivity tomography surveys for geohydrological studies in the Karoo rocks is evaluated through theoretical considerations, numerical modelling and ... -
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 ... -
