A holistic hydrogeological environmental site risk assessment methodology for the fertilizer industry in South Africa
(University of the Free State, 2013-04)
English: There has been a definitive increase in environmental legislation over the past decade. These new environmental laws established principles such as duty of care and the polluter pay principle. Numerous companies ...
Investigating the possibility of targeting major dolerite intrusives to supplement municipal water supply in Bloemfontein: a geophysical approach
(University of the Free State, 2017-02)
The city of Bloemfontein is currently relying on surface water sources for its potable water supply. However, Bloemfontein is located in a semi-arid area, which means that the surface water resources are unreliable and ...
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 ...
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 ...
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 ...
Experimental determination of rock hydrological properties using elastic parameters
(University of the Free State, 2007-11)
English: As groundwater becomes increasingly vital as a viable source of fresh water in arid or remote areas, where surface water supplies are insufficient to sustain life, agriculture and industry, it has become important ...
The occurrance of groundwater in the Limpopo Province north of latitude 23⁰S
(University of the Free State, 2012-04)
Abstract not available
Application of electroseismic techniques to geohydrological investigations in Karoo rocks
(University of the Free State, 2003-11)
English: The possibility of using surface electroseismic (ES) methods for groundwater exploration in fractured Karoo rocks is studied by investigating the criteria of vertical and lateral resolution of surface ES data and ...
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 ...
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 ...
