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 ...
Estimation of recharge using a revised CRD method
(Water Research Commission, 2001)
The cumulative rainfall departure (CRD) method, based on the water-balance principle, is often used for mimicking of
water level fluctuations. Because of its simplicity and minimal requirement of spatial data, the CRD ...
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 water balance approach to the sustainable management of groundwater in South Africa
(Water Research Commission, 2000)
The water balance approach, based on the principles of conservation of mass, is applied to the issue of sustainable groundwater
management in South Africa, incorporating the ethos of the National Water Act of 1998, ...
Conservation status of large branchiopods in the Western Cape, South Africa
(Springer Verlag, 2007)
Temporary wetlands are an ecologically and economically important habitat in South Africa. They harbor large branchiopods, known to be flagship species of nonpermanent aquatic habitats, and sensitive to land use changes. ...
Groundwater discharges to aquatic ecosystems associated with the Table Mountain Group (TMG) aquifer: a conceptual model
(Water Research Commission, 2008)
This paper reports on a conceptual model that was developed to describe the different groundwater discharge ‘types’ from
the Table Mountain Group (TMG) aquifer, that contributes to the different components of the flow ...
Snow impact on groundwater recharge in Table Mountain Group aquifer systems with a case study of the Kommissiekraal River catchment South Africa
(Water Research Commission, 2005)
Snowmelt in the mountainous areas of the Table Mountain Group (TMG) in South Africa is believed to be one of sources of
groundwater recharge in some winter seasons. This paper provides a scientific assessment of snow ...
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 ...
