A tensor approach to the estimation of hydraulic conductivities in Table Mountain Group aquifers of South Africa
(Water Research Commission, 2006)Based on the field measurements of the physical properties of fractured rocks, the anisotropic properties of hydraulic conductivity (HC) of the fractured rock aquifer can be assessed and presented using a tensor approach ... -
A hydrogeomorphological approach to quantification of groundwater discharge to streams in South Africa
(Water Research Commission, 2002)In South Africa, the flow requirements for maintaining the normal functioning of aquatic ecosystems is termed the “ecological reserve”, and these should be determined when a licence application for water allocation is ... -
Capture zone simulation for boreholes located in fractured dykes using the linesink concept
(Water Research Commission, 2002)Delineation of capture zones for groundwater source protection is normally performed by using numerical codes which are based on the porous medium flow equation. However, boreholes are often sited in or along permeable ... -

On the use of electrical resistivity methods in monitoring infiltration of salt fluxes in dry coal ash dumps in Mpumalanga, South Africa
(Water Research Commission, 2013)One of the principal environmental concerns relating to coal combustion waste disposal is the potential for groundwater contamination from salt fluxes and trace elements that may be leached into the underlying groundwater ... -
Sustainable groundwater use, the capture principle, and adaptive management
(Water Research Commission, 2006)The purpose of this paper is to review the case for using ‘capture’ rather than recharge as the conceptual basis for sustainable groundwater use in South Africa. Capture refers to the sum of the increase in recharge and ... -
Groundwater management issues in Southern Africa – An IWRM perspective
(Water Research Commission, 2008)In contrast to its strategic role as essential resource to help achieve community development and poverty alleviation in the Southern African Development Community (SADC), groundwater has remained a poorly understood and ... -
Assessment of microbial contamination of groundwater in upper Limphasa River catchment, located in a rural area of northern Malawi
(Water Research Commission, 2012)In rural Africa, scientific evidence is often lacking to guide the scaling-up of groundwater as the safest source of potable water. An investigation was conducted in the Upper Limphasa Catchment in northern Malawi to ... -
Salinity of irrigation water in the Philippi farming area of the Cape Flats, Cape Town, South Africa
(Water Research Commission, 2013)This paper explores the nature, source and spatial variation of the salinity of water used for irrigation in a coastal urban farming area in Cape Town, South Africa, where water from the Cape Flats aquifer is drawn into ...
