    Groundwater discharges to aquatic ecosystems associated with the Table Mountain Group (TMG) aquifer: a conceptual model 

    Roets, Wietsche; Xu, Yongxin; Raitt, Lincoln; Brendonck, Luc (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 

    Wu, Yong; Xu, Yongxin (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 ...

    On the use of electrical resistivity methods in monitoring infiltration of salt fluxes in dry coal ash dumps in Mpumalanga, South Africa 

    Muchingami, Innocent; Nel, Jacobus; Xu, Yongxin; Steyl, Gideon; Reynolds, Kelley (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 ...

    Borehole dilution experiment in a Karoo aquifer in Bloemfontein 

    Xu, Yongxin; van Tonder, Gerrit J.; van Wyk, B.; van Wyk, E.; Aleobua, B. (Water Research Commission, 1997)
    This paper shows that a borehole dilution experiment using common salt is a useful technique for better understanding of some hydrogeological features of a fractured aquifer. A sense of such tracer experiments was performed ...

    Sustainable groundwater use, the capture principle, and adaptive management 

    Seward, Paul; Xu, Yongxin; Brendonck, Luc (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 ...

    A tensor approach to the estimation of hydraulic conductivities in Table Mountain Group aquifers of South Africa 

    Lin, Lixiang; Xu, Yongxin (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 three-tier approach to protect groundwater resources in South Africa 

    Xu, Yongxin; Reynders, A.G. (Water Research Commission, 1995)
    The quality of groundwater is affected by many activities occurring on the surface of the earth. A pro-active protection approach is required to avoid the costly and technology difficult exercise of groundwater remediation. ...

    Review: groundwater management and groundwater/surface-water interaction in the context of South African water policy 

    Levy, Jonathan; Xu, Yongxin (Springer Verlag, 2011)
    Groundwater/surface-water interaction is receiv¬ing increasing focus in Africa due to its importance to ecologic systems and sustainability. In South Africa's 1998 National Water Act (NWA), water-use licenses, including ...
